Why two NDCs? The FDA registers this code as 70121-1647-7 — a 5-4-1 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the package segment → 70121-1647-07. Same drug, same package — only the format differs.

🩺 Clinical

Label name TIGECYCLINE 50 MG VIAL Ingredient Tigecycline
📖 What it is MedlinePlus · NLM

Tigecycline injection used to treat certain serious infections caused by bacteria.  Tigecycline injection is in a class of medications called tetracycline antibiotics. It works by killing bacteria that cause infection. Antibiotics such as tigecycline injection will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🔒Generic approved by FDA, but pharmacy availability is not confirmed

The FDA lists approved generic versions of this medicine, but that does not always mean a pharmacy can get one today. Patent rules, launch agreements, supply and pricing can affect when generics actually arrive.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through Apr 2033. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.
📅 FDA approved Aug 2, 2018 AP TE-rated RLD RS ⏳ ~6.6 yr to latest listed protection

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

LOE
Substance patent Formulation patent Method-of-use patent Exclusivity Pediatric +6mo
🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of TIGECYCLINE 50 MG VIAL?
Yes — an FDA-approved generic equivalent is listed in the FDA Orange Book for TIGECYCLINE 50 MG VIAL. See the alternatives section for substitutable, lower-cost products.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

🗺️ Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for 70121-1647-07, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Tigecycline — the program that covers self-administered drugs. 3 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Tigecycline. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 70121-1647-7, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 70121-1647-07, written without dashes as 70121164707. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 70121-1647-07, the first segment (70121) is the labeler code FDA assigned to Amneal Pharmaceuticals LLC; the middle segment (1647) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (07) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Amneal Pharmaceuticals LLC. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Amneal Pharmaceuticals LLC is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J3243 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

1.4Limitations of Use Tigecycline for injection is not indicated for the treatment of diabetic foot infections. A clinical trial failed to demonstrate non-inferiority of tigecycline for treatment of diabetic foot infections. Tigecycline for injection is not indicated for the treatment of hospital-acquired or ventilator-associated pneumonia.

In a comparative clinical trial, greater mortality and decreased efficacy were reported in tigecycline-treated patients [see Warnings and Precautions (5.2) ].

1.5Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of tigecycline for injection and other antibacterial drugs, tigecycline for injection should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Appropriate specimens for bacteriological examination should be obtained in order to isolate and identify the causative organisms and to determine their susceptibility to tigecycline. Tigecycline for injection may be initiated as empiric monotherapy before results of these tests are known.

2.1Recommended Adult Dosage The recommended dosage regimen for tigecycline for injection is an initial dose of 100 mg, followed by 50 mg every 12 hours. Intravenous infusions of tigecycline for injection should be administered over approximately 30 minutes to 60 minutes every 12 hours. The recommended duration of treatment with tigecycline for injection for complicated skin and skin structure infections or for complicated intra-abdominal infections is 5 days to 14 days.

The recommended duration of treatment with tigecycline for injection for community-acquired bacterial pneumonia is 7 days to 14 days. The duration of therapy should be guided by the severity and site of the infection and the patient’s clinical and bacteriological progress.

2.2Dosage in Patients With Hepatic Impairment No dosage adjustment is warranted in patients with mild to moderate hepatic impairment (Child Pugh A and Child Pugh B). In patients with severe hepatic impairment (Child Pugh C), the initial dose of tigecycline for injection should be 100 mg followed by a reduced maintenance dose of 25 mg every 12 hours. Patients with severe hepatic impairment (Child Pugh C) should be treated with caution and monitored for treatment response [see Clinical Pharmacology (12.3) and Use in Specific Populations (8.6) ] .

2.3Dosage in Pediatric Patients The safety and efficacy of the proposed pediatric dosing regimens have not been evaluated due to the observed increase in mortality associated with tigecycline for injection in adult patients. Avoid use of tigecycline for injection in pediatric patients unless no alternative antibacterial drugs are available. Under these circumstances, the following doses are suggested: Pediatric patients aged 8 years to 11 years should receive 1.2 mg/kg of tigecycline for injection every 12 hours by intravenous infusion over approximately 30 minutes to 60 minutes to a maximum dose of 50 mg of tigecycline for injection every 12 hours.

Pediatric patients aged 12 years to 17 years should receive 50 mg of tigecycline for injection every 12 hours by intravenous infusion over approximately 30 minutes to 60 minutes. The proposed pediatric doses of tigecycline for injection were chosen based on exposures observed in pharmacokinetic trials, which included small numbers of pediatric patients [see Use in Specific Populations (8.4) and Clinical Pharmacology (12.3) ] . There are no data to provide dosing recommendations in pediatric patients with hepatic impairment.

2.4Monitoring of Blood Coagulation Parameters Obtain baseline blood coagulation parameters, including fibrinogen, and continue to monitor regularly during treatment with tigecycline [see Warnings and Precautions (5.6) ] .

2.5Preparation and Administration Reconstitution and Dilution: Each vial of tigecycline for injection should be reconstituted with 5.3 mL of 0.9% Sodium Chloride Injection, USP, 5% Dextrose Injection, USP, or Lactated Ringer’s Injection, USP to achieve a concentration of 10 mg/mL of tigecycline. (Note: Each vial contains a 6% overage. Thus, 5 mL of reconstituted solution is equivalent to 50 mg of the drug.) The vial should be gently swirled until the drug dissolves.

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS All-Cause Mortality : A meta-analysis of Phase 3 and 4 clinical trials demonstrated an increase in all-cause mortality in tigecycline-treated patients compared to controls with a risk difference of 0.6% (95% CI 0.1, 1.2). The cause of this increase has not been established. An increase was also seen in a meta-analysis limited to the approved indications [0.6% (95% CI 0.0, 1.2)].

The greatest difference in mortality was seen in tigecycline-treated patients with ventilator-associated pneumonia. (5.1 , 5.2) Anaphylactic Reactions : have been reported with tigecycline, and may be life-threatening. Avoid use in patients with known hypersensitivity to tetracyclines.

(5.3) Hepatic Adverse Effects : have been reported with tigecycline. Patients who develop abnormal liver function tests during tigecycline therapy should be monitored for evidence of worsening hepatic function and evaluated for risk/benefit of continuing tigecycline therapy. (5.4) Pancreatitis : including fatalities, has been reported with tigecycline.

If pancreatitis is suspected, then consider stopping tigecycline. (5.5) Monitoring of Blood Coagulation Parameters: Hypofibrinogenemia has been reported with tigecycline for injection. Monitor blood coagulation parameters, including fibrinogen, at baseline and regularly during treatment with tigecycline for injection.

(5.6) Tooth Discoloration and Enamel Hypoplasia : The use of tigecycline for injection during tooth development (last half of pregnancy, infancy, and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown) and enamel hypoplasia. (5.7) Inhibition of Bone Growth : The use of tigecycline for injection during the second and third trimester of pregnancy, infancy, and childhood up to the age of 8 years may cause reversible inhibition of bone growth. (5.8) Clostridioides difficile- Associated Diarrhea (CDAD) : evaluate if diarrhea occurs.

(5.9)

5.1All-Cause Mortality An increase in all-cause mortality has been observed in a meta-analysis of Phase 3 and 4 clinical trials in tigecycline-treated patients versus comparator-treated patients. In all 13 Phase 3 and 4 trials that included a comparator, death occurred in 4.0% (150/3788) of patients receiving tigecycline and 3.0% (110/3646) of patients receiving comparator drugs. In a pooled analysis of these trials, based on a random effects model by trial weight, the adjusted risk difference of all-cause mortality was 0.6% (95% CI 0.1, 1.2) between tigecycline and comparator-treated patients.

An analysis of mortality in all trials conducted for approved indications (cSSSI, cIAI, and CABP), including post-market trials showed an adjusted mortality rate of 2.5% (66/2640) for tigecycline and 1.8% (48/2628) for comparator, respectively. The adjusted risk difference for mortality stratified by trial weight was 0.6% (95% CI 0.0, 1.2). The cause of this mortality difference has not been established.

Generally, deaths were the result of worsening infection, complications of infection or underlying co-morbidities. Tigecycline for injection should be reserved for use in situations when alternative treatments are not suitable [see Boxed Warning , Indications and Usage (1.4) , Warnings and Precautions (5.2) and Adverse Reactions (6.1) ].

5.2Mortality Imbalance and Lower Cure Rates in Hospital-Acquired Pneumonia A trial of patients with hospital acquired, including ventilator-associated, pneumonia failed to demonstrate the efficacy of tigecycline. In this trial, patients were randomized to receive tigecycline (100 mg initially, then 50 mg every 12 hours) or a comparator. In addition, patients were allowed to receive specified adjunctive therapies.

The sub-group of patients with ventilator-associated pneumonia who received tigecycline had lower cure rates (47.9% versus 70.1% for the clinically evaluable population). In this trial, greater mortality was seen in patients with ventilator-associated pneumonia who receiv…

7 DRUG INTERACTIONS Warfarin : Suitable anticoagulation test should be monitored if tigecycline for injection is administered to patients receiving warfarin. (7.1) Calcineurin Inhibitors : Serum concentrations of calcineurin inhibitors (e.g., tacrolimus, cyclosporine) should be monitored during treatment with tigecycline for injection due to risk of toxicity. (7.2)

7.1Warfarin Prothrombin time or other suitable anticoagulation test should be monitored if tigecycline for injection is administered with warfarin [see Clinical Pharmacology (12.3) ] .

7.2Calcineurin Inhibitors Concomitant use of tigecycline for injection and calcineurin inhibitors such as tacrolimus or cyclosporine may lead to an increase in serum trough concentrations of the calcineurin inhibitors. Therefore, serum concentrations of the calcineurin inhibitor should be monitored during treatment with tigecycline for injection to avoid drug toxicity.

7.3Oral Contraceptives Concurrent use of antibacterial drugs with oral contraceptives may render oral contraceptives less effective.

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS Lactation: Avoid breastfeeding for longer than 3 weeks while taking tigecycline for injection. A lactating woman may pump and discard breast milk during treatment and for 9 days after the last dose of tigecycline. (8.2) Pediatrics: Use in patients under 18 years of age is not recommended. Pediatric trials were not conducted because of the higher risk of mortality seen in adult trials (8.4)

8.1Pregnancy Risk Summary Tigecycline for injection, like other tetracycline class antibacterial drugs, may cause permanent discoloration of deciduous teeth and reversible inhibition of bone growth when administered during the second and third trimesters of pregnancy [see Warnings and Precautions (5.7) , (5.8) , Data , and Use in Specific Populations (8.4) ]. There are no available data on the risk of major birth defects or miscarriage following the use of tigecycline for injection during pregnancy. Administration of intravenous tigecycline in pregnant rats and rabbits during the period of organogenesis was associated with reduction in fetal weights and an increased incidence of skeletal anomalies (delays in bone ossification) at exposures of 5 and 1 times the human exposure at the recommended clinical dose in rats and rabbits, respectively.

Advise the patient of the potential risk to the fetus if tigecycline for injection is used during the second or third trimester. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

In the U. S. general population, the estimated background risk in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data The use of tetracycline-class antibacterial drugs, that includes tigecycline for injection, during tooth development (second and third trimester of pregnancy) may cause permanent discoloration of deciduous teeth.

This adverse reaction is more common during long-term use of tetracyclines but has been observed following repeated short-term courses. Tigecycline for injection may cause reversible inhibition of bone growth when administered during the second and third trimesters of pregnancy. A decrease in fibula growth rate has been observed in premature infants given oral tetracycline in doses of 25 mg/kg every 6 hours.

Animal Data In embryo-fetal development studies, tigecycline was administered during the period of organogenesis at doses up to 12 mg/kg/day in rats and 4 mg/kg in rabbits or 5 and 1 times the systemic exposure at the recommended clinical dose, respectively. In the rat study, decreased fetal weight and fetal skeletal variations (reduced ossification of the pubic, ischial, and supraoccipital bones and increased incidences of rudimentary 14 th rib) were observed in the presence of maternal toxicity at 12 mg/kg/day (5 times the recommended clinical dose based on systemic exposure).

In rabbits, decreased fetal weights were observed in the presence of maternal toxicity at 4 mg/kg (equivalent to the human exposure at the recommended clinical dose). In preclinical safety studies, 14 C-labeled tigecycline crossed the placenta and was found in fetal tissues.

8.2Lactation Risk Summary There are no data on the presence of tigecycline in human milk; however, tetracycline-class antibacterial drugs are present in breast milk. It is not known whether tigecycline has an effect on the breastfed infant or on milk production. Tigecycline has low oral bioavailability; therefore, infant exposure is expected to be low.

Tigecycline is present in rat milk with little or no systemic exposure to tigecycline in nursing pups as a result of exposure via maternal milk. When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for tigecycline for injection and any…

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Tigecycline is a tetracycline class antibacterial drug [see Microbiology (12.4) ].

12.2Pharmacodynamics Cardiac Electrophysiology No significant effect of a single intravenous dose of tigecycline 50 mg or 200 mg on QTc interval was detected in a randomized, placebo- and active-controlled four-arm crossover thorough QTc study of 46 healthy subjects.

12.3Pharmacokinetics The mean pharmacokinetic parameters of tigecycline after single and multiple intravenous doses based on pooled data from clinical pharmacology studies are summarized in Table 3. Intravenous infusions of tigecycline were administered over approximately 30 to 60 minutes. Table 3.

Mean (CV%) Pharmacokinetic Parameters of Tigecycline Single Dose Multiple Dose a 100 mg 50 mg every 12h (N=224) (N=103) C max (mcg/mL) b 1.45 (22%) 0.87 (27%) C max (mcg/mL) c 0.90 (30%) 0.63 (15%) AUC (mcg·h/mL) 5.19 (36%) - - AUC 0-24h (mcg·h/mL) - - 4.70 (36%) C min (mcg/mL) - - 0.13 (59%) t 1/2 (h) 27.1 (53%) 42.4 (83%) CL (L/h) 21.8 (40%) 23.8 (33%) CL r (mL/min) 38.0 (82%) 51.0 (58%) V ss (L) 568 (43%) 639 (48%) a 100 mg initially, followed by 50 mg every 12 hours b 30-minute infusion c 60-minute infusion Distribution The in vitro plasma protein binding of tigecycline ranges from approximately 71% to 89% at concentrations observed in clinical studies (0.1 to 1 mcg/mL).

The steady-state volume of distribution of tigecycline averaged 500 to 700 L (7 to 9 L/kg), indicating tigecycline is extensively distributed beyond the plasma volume and into the tissues. Following the administration of tigecycline 100 mg followed by 50 mg every 12 hours to 33 healthy volunteers, the tigecycline AUC 0-12h (134 mcg·h/mL) in alveolar cells was approximately 78-fold higher than the AUC 0-12h in the serum, and the AUC 0-12h (2.28 mcg·h/mL) in epithelial lining fluid was approximately 32% higher than the AUC 0-12h in serum.

The AUC 0-12h (1.61 mcg·h/mL) of tigecycline in skin blister fluid was approximately 26% lower than the AUC 0-12h in the serum of 10 healthy subjects. In a single-dose study, tigecycline 100 mg was administered to subjects prior to undergoing elective surgery or medical procedure for tissue extraction. Concentrations at 4 hours after tigecycline administration were higher in gallbladder (38-fold, n=6), lung (3.7-fold, n=5), and colon (2.3-fold, n=6), and lower in synovial fluid (0.58-fold, n=5), and bone (0.35-fold, n=6) relative to serum.

The concentration of tigecycline in these tissues after multiple doses has not been studied. Elimination Metabolism Tigecycline is not extensively metabolized. In vitro studies with tigecycline using human liver microsomes, liver slices, and hepatocytes led to the formation of only trace amounts of metabolites.

In healthy male volunteers receiving 14 C-tigecycline, tigecycline was the primary 14 C-labeled material recovered in urine and feces, but a glucuronide, an N-acetyl metabolite, and a tigecycline epimer (each at no more than 10% of the administered dose) were also present. Tigecycline is a substrate of P-glycoprotein (P-gp) based on an in vitro study using a cell line overexpressing P-gp. The potential contribution of P-gp-mediated transport to the in vivo disposition of tigecycline is not known.

Excretion The recovery of total radioactivity in feces and urine following administration of 14 C-tigecycline indicates that 59% of the dose is eliminated by biliary/fecal excretion, and 33% is excreted in urine. Approximately 22% of the total dose is excreted as unchanged tigecycline in urine. Overall, the primary route of elimination for tigecycline is biliary excretion of unchanged tigecycline and its metabolites.

Glucuronidation and renal excretion of unchanged tigecycline are secondary routes. Specific Populations Hepatic Impairment In a study comparing 10 patients with mild hepatic impairment (Child Pugh A), 10 patients with moderate hepatic impairment (Child Pugh B), and 5 patients with severe…

💬 Information for Patients ~2 min read ▾

17 PATIENT COUNSELING INFORMATION Tooth Discoloration and Inhibition of Bone Growth Advise pregnant women that tigecycline for injection may cause permanent discoloration of deciduous teeth and reversible inhibition of bone growth when administered during the second and third trimesters of pregnancy [see Warnings and Precautions (5.7 , 5.8) and Use in Specific Populations (8.1 , 8.4) ]. Lactation Advise a woman not to breastfeed for longer than 3 weeks while taking tigecycline for injection because of the lack of data on effects due to prolonged breastfeeding, and the theoretical risk of dental discoloration and inhibition of bone growth.

Women may also consider reducing infant exposure through pumping and discarding breastmilk during and for 9 days after the last dose of tigecycline [see Use in Specific Populations (8.2) ] . Diarrhea Advise patients, their families, or caregivers that diarrhea is a common problem caused by antibacterial drugs, including tigecycline for injection. Sometimes, frequent watery or bloody diarrhea may occur and may be a sign of a more serious intestinal infection.

If severe watery or bloody diarrhea develops, advise patients to contact his or her healthcare provider [see Warnings and Precautions (5.9) ]. Development of Resistance Patients should be counseled that antibacterial drugs including tigecycline for injection should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold).

When tigecycline for injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by tigecycline for injection or other antibacterial drugs in the future.
