Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
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.
🛈 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.

⛔ Contraindications ▾
4 CONTRAINDICATIONS NUZYRA is contraindicated in patients with known hypersensitivity to omadacycline or tetracycline class antibacterial drugs, or to any of the excipients [see Warnings andPrecautions (5.3) and Adverse Reactions (6.1) ]. Known hypersensitivity to omadacycline, tetracycline class antibacterial drugs or any of the excipients in NUZYRA ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Tooth Discoloration and Enamel Hypoplasia : The use of NUZYRA 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. ( 5.1 , 8.1 , 8.4 ) Inhibition of Bone Growth: The use of NUZYRA 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. ( 5.2 , 8.1 , 8.4 ) Clostridioides difficile -Associated Diarrhea : Evaluate if diarrhea occurs.
( 5.4 )
5.1Tooth Discoloration and Enamel Hypoplasia The use of NUZYRA during tooth development (last half of pregnancy, infancy, and childhood up to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown). This adverse reaction is more common during long-term use of the tetracycline class drugs, but it has been observed following repeated short-term courses. Enamel hypoplasia has also been reported with tetracycline class drugs.
Advise the patient of the potential risk to the fetus if NUZYRA is used during the second or third trimester of pregnancy [see Use in Specific Populations (8.1 , 8.4) ].
5.2Inhibition of Bone Growth The use of NUZYRA 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. All tetracyclines form a stable calcium complex in any bone-forming tissue. A decrease in fibula growth rate has been observed in premature infants given oral tetracycline in doses of 25 mg/kg every 6 hours.
This reaction was shown to be reversible when the drug was discontinued. Advise the patient of the potential risk to the fetus if NUZYRA is used during the second or third trimester of pregnancy [see Use in Specific Populations (8.1 , 8.4) ] .
5.3Hypersensitivity Reactions Hypersensitivity reactions have been reported with NUZYRA [see Adverse Reactions (6.1) ]. Life-threatening hypersensitivity (anaphylactic) reactions have been reported with other tetracycline class antibacterial drugs. NUZYRA is structurally similar to other tetracycline class antibacterial drugs and is contraindicated in patients with known hypersensitivity to tetracycline class antibacterial drugs [see Contraindications (4) ] .
Discontinue NUZYRA if an allergic reaction occurs.
5.4Clostridioides difficile- Associated Diarrhea Clostridioides difficile- associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile . C. difficile produces toxins A and B which contribute to the development of CDAD.
Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial drug treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated.
5.5Tetracycline Class Effects NUZYRA is structurally similar to tetracycline class of antibacterial drugs and may have similar adverse reactions. Adverse reactions including photosensitivity, fixed drug eruption, pseudotumor cerebri, and anti-anabolic action which has led to increased BUN, azotemia, acidosis, hyperphosphatemia, pancreatitis, and abnormal liver function tests, have been reported for other tetracycline class antibacterial drugs, and may occu… [Excerpted — this section continues on DailyMed.]
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described in greater detail in the Warnings and Precautions section of labeling: Tooth Development and Enamel Hypoplasia [see Warnings and Precautions (5.1) ] Inhibition of Bone Growth [see Warnings and Precautions (5.2) ] Hypersensitivity Reactions [see Warnings and Precautions (5.3) ] Tetracycline Class Effects [see Warnings and Precautions ( 5.5 )] ABSSSI: The most common adverse reactions (incidence ≥2%) are nausea, vomiting, infusion site reactions, alanine aminotransferase increased, aspartate aminotransferase increased, headache and diarrhea.
CABP : The most common adverse reactions (incidence ≥2%) are alanine aminotransferase increased, headache, hypertension, and aspartate aminotransferase increased.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Overview of the Safety Evaluation of NUZYRA NUZYRA was evaluated in three Phase 3 pivotal clinical trials (Trial 1, Trial 2 and Trial 3) and one Phase 3 postmarketing clinical trial (Trial 4). These trials included one pivotal Phase 3 trial in CABP patients (Trial 1), one Phase 3 postmarketing trial in CABP patients (Trial 4), and two pivotal Phase 3 trials in ABSSSI patients (Trial 2 and Trial 3).
Across all Phase 3 trials, a total of 1409 patients were treated with NUZYRA. In Trials 2 and 3, 691 patients with ABSSSI received NUZYRA, of which 368 patients were treated with only oral NUZYRA. In Trials 1 and 4, 718 patients with CABP were treated with NUZYRA.
Clinical Trial Experience in Patients with Community-Acquired Bacterial Pneumonia Trial 1 was a Phase 3 CABP trial that enrolled 774 adult patients, 386 randomized to NUZYRA (382 received at least one dose of NUZYRA and 4 patients did not receive the study drug) and 388 randomized to moxifloxacin (all 388 received at least one dose of moxifloxacin). The mean age of patients treated with NUZYRA was 61 years (range 19 to 97 years) and 42% were greater than or equal to 65 years of age. Overall, patients treated with NUZYRA were predominantly male (53.7%), white (92.4%), and had a mean body mass index (BMI) of 27.3 kg/m 2 .
Approximately 47% of NUZYRA treated patients had CrCl <90 ml/min. Patients were administered an IV to oral switch dosage regimen of NUZYRA. The total treatment duration was 7 to 14 days.
Mean duration of IV treatment was 5.7 days and mean total duration of treatment was 9.6 days in both treatment arms. Trial 4 was a Phase 3 CABP trial that enrolled 670 adult patients, 336 randomized to NUZYRA (all 336 received at least one dose of NUZYRA) and 334 randomized to moxifloxacin (332 received at least one dose of moxifloxacin and 2 patients did not receive the study drug). The mean age of patients treated with NUZYRA was 63.3 years (range 23 to 96 years) and 47.6% were greater than or equal to 65 years of age.
Overall, patients treated with NUZYRA were predominantly male (53.0%), white (99.7%), and had a mean body mass index (BMI) of 27.0 kg/m 2 . Approximately 54% of NUZYRA treated patients had CrCl <90 ml/min. Patients were administered an IV to oral switch dosage regimen of NUZYRA.
The total treatment duration was 7 to 10 days with up to 14 days allowed for patients with positive blood cultures at the Screening visit. Mean duration of IV treatment was 6.6 days and mean total duration of treatment was 9.0 days in both treatment arms. Serious Adverse Reactions and Adverse Reactions Leading to Discontinuation In Trial 1, a total of 23/382 (6.0%) patients treated with NUZYRA and 26/388 (6.7%) patients treated with moxifloxacin experienced ser… [Excerpted — this section continues on DailyMed.]
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage while taking NUZYRA. ( 7.1 ) Absorption of tetracyclines, including NUZYRA, is impaired by antacids containing aluminum, calcium, or magnesium, bismuth subsalicylate and iron containing preparations. ( 2.1 , 7.2 )
7.1Anticoagulant Drugs Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage while also taking NUZYRA.
7.2Antacids and Iron Preparations Absorption of oral tetracyclines, including NUZYRA, is impaired by antacids containing aluminum, calcium, or magnesium, bismuth subsalicylate, and iron containing preparations [see Dosage and Administration (2.1) ].
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation : Breastfeeding is not recommended during treatment with NUZYRA. ( 8.2 )
8.1Pregnancy Risk Summary NUZYRA, like other tetracycline class antibacterial drugs, may cause discoloration of deciduous teeth and reversible inhibition of bone growth when administered during the second and third trimester of pregnancy [see Warnings and Precautions ( 5.1 , 5.2) , Data, Use in Specific Populations ( 8.4 )]. The limited available data of NUZYRA use in pregnant women is insufficient to inform drug associated risk of major birth defects and miscarriages. Animal studies indicate that administration of omadacycline during the period of organogenesis resulted in fetal loss and/or congenital malformations in pregnant rats and rabbits at 7 times and 3 times the mean AUC exposure, respectively, of the clinical intravenous dose of 100 mg and the oral dose of 300 mg.
Reductions in fetal weight occurred in rats at all administered doses (see Data ). In a fertility study, administration to rats during mating and early pregnancy resulted in embryo loss at 20 mg/kg/day; systemic exposure based on AUC was approximately equal to the clinical exposure level [see Nonclinical Toxicology ( 13.1) ] . Results of studies in rats with omadacycline have shown tooth discoloration.
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 of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15-20%.
Data Animal Data Intravenous infusion of omadacycline to pregnant rats during organogenesis (gestation days 6-17) at doses of 5 to 80 mg/kg/day resulted in maternal lethality at 80 mg/kg/day. Increased embryo-fetal lethality and fetal malformations (whole body edema) occurred at 60 mg/kg/day (7 times the clinical AUC), dose-dependent reductions in fetal body weight occurred at all doses, and delayed skeletal ossification occurred at doses as low as 10 mg/kg/day (Systemic exposure based on AUC at a similar dose in unmated female rats in a separate study was approximately half the clinical exposure).
In pregnant rabbits, intravenous infusion of 5, 10 or 20 mg/kg/day during organogenesis (gestation days 7-18) resulted in maternal lethality and body weight loss at 20 mg/kg/day. Embryo-fetal lethality, congenital malformations of the skeleton, and reduced fetal weight also occurred at 20 mg/kg/day (7 times the clinical AUC). Cardiac and lung malformations were present in dose-related incidence at 10 and 20 mg/kg/day.
The fetal no-adverse-effect-level in the rabbit embryo-fetal development study was 5 mg/kg/day, at approximately 1.2 times the clinical steady state AUC. Intravenous infusion of omadacycline to pregnant and lactating rats at doses of 7.5, 15 and 30 mg/kg/day did not adversely affect survival, growth (other than lower pup body weights and/or gains at the high dose that were only statistically significant at sporadic intervals), postnatal development, behavior, or reproductive capability of offspring at maternal doses up to 30 mg/kg/day (approximately equivalent to 3 times the IV clinical dose of 100 mg/day, based on doses normalized for total body surface area), the highest dose tested, although dosing was discontinued early in a number of animals in this group due to injection site intolerance.
Results of animal studies indicate that tetracyclines cross the placenta, are found in fetal tissues, and can have toxic effects on the developing fetus (often related to retardation of skeletal development). Evidence of embryotoxicity also has been noted in animals treated early in pregnancy.

🤰 Pregnancy ▾
8.1Pregnancy Risk Summary NUZYRA, like other tetracycline class antibacterial drugs, may cause discoloration of deciduous teeth and reversible inhibition of bone growth when administered during the second and third trimester of pregnancy [see Warnings and Precautions ( 5.1 , 5.2) , Data, Use in Specific Populations ( 8.4 )]. The limited available data of NUZYRA use in pregnant women is insufficient to inform drug associated risk of major birth defects and miscarriages. Animal studies indicate that administration of omadacycline during the period of organogenesis resulted in fetal loss and/or congenital malformations in pregnant rats and rabbits at 7 times and 3 times the mean AUC exposure, respectively, of the clinical intravenous dose of 100 mg and the oral dose of 300 mg.
Reductions in fetal weight occurred in rats at all administered doses (see Data ). In a fertility study, administration to rats during mating and early pregnancy resulted in embryo loss at 20 mg/kg/day; systemic exposure based on AUC was approximately equal to the clinical exposure level [see Nonclinical Toxicology ( 13.1) ] . Results of studies in rats with omadacycline have shown tooth discoloration.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of NUZYRA in pediatric patients below the age of 18 years have not been established. Due to the adverse effects of the tetracycline class of drugs, including NUZYRA on tooth development and bone growth, use of NUZYRA in pediatric patients less than 8 years of age is not recommended [see Warnings and Precautions (5.1 , 5.2) ].
🧓 Geriatric Use ▾
8.5Geriatric Use Of the total number of patients who received NUZYRA for ABSSSI in clinical trials 2 and 3 (n=691), 57 (8.2%) patients were ≥65 years of age, including 20 (2.9%) patients who were ≥75 years of age. Of the total number of patients who received NUZYRA for CABP in clinical trials 1 and 4 (n=718), 330 (46%) patients were ≥65 years of age, including 156 (21.7%) patients who were ≥75 years of age [see Clinical Studies (14)] . No overall differences in safety or effectiveness were observed between these patients and younger adult patients.
However, greater sensitivity of some older individuals cannot be ruled out. No significant difference in NUZYRA exposure was observed between healthy elderly subjects and younger subjects following a single 100 mg IV dose of NUZYRA [see Clinical Pharmacology (12.3) ] .
🆘 Overdosage ▾
10 OVERDOSAGE No specific information is available on the treatment of overdosage with NUZYRA. Following a 100 mg single dose intravenous administration of omadacycline, 8.9% of dose is recovered in the dialysate.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action NUZYRA is an antibacterial drug [see Microbiology (12.4) ].
12.2Pharmacodynamics Cardiac Electrophysiology Based on the nonclinical and clinical data, including electrocardiogram evaluation in the phase 3 clinical trials, one of which had moxifloxacin as a control group, no clinically relevant QTc prolongation was observed at the maximum recommended dose of omadacycline. Cardiac Physiology-Increase in Heart Rate In phase 1 studies conducted in healthy volunteers, reversible dose-dependent increases in heart rate have been observed following administration of single and multiple doses of omadacycline.
The clinical implication of this finding is unknown [see Adverse Reactions (6.1) ]. In a standard radiolabeled ligand binding assays, omadacycline was shown to inhibit binding of H-scopolamine to the M2 subtype of the muscarinic acetylcholine receptor. In the heart, muscarinic M2 receptors serve as mediators of the parasympathetic input that normally is received via the vagus nerve and stimulation of the receptor increases membrane potassium conductance through the acetylcholine-dependent channel, which slows depolarization and reduces pacemaker activity in the sinoatrial node.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Nausea and Vomiting Advise patients that nausea and vomiting can be an adverse reaction to NUZYRA. Advise patients that a greater proportion of patients who received the oral loading dose of NUZYRA for treatment of ABSSSI experienced nausea and vomiting. Allergic Reactions Advise patients that allergic reactions, including serious allergic reactions, could occur and that serious allergic reactions require immediate treatment.
Ask the patient about any previous hypersensitivity reactions to NUZYRA, or other tetracycline class antibacterials [see Warnings and Precautions (5.3) ] . Administration with Food Instruct patients to fast 4 hours before and 2 hours after taking NUZYRA tablets and not to consume dairy products, antacids, or multivitamins for 4 hours after taking NUZYRA tablets [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) ] . Tooth Discoloration and Inhibition of Bone Growth Advise patients that NUZYRA, like other tetracycline class drugs, may cause permanent tooth discoloration of deciduous teeth and reversible inhibition of bone growth when administered during the second and third trimesters of pregnancy.
Tell your healthcare provider right away if you become pregnant during treatment [see Warnings and Precautions (5.1 , 5.2) and Use in Specific Populations (8.1 , 8.4) ]. Lactation Advise women not to breastfeed during treatment with NUZYRA and for 4 days after the last dose [see Use in Specific Populations (8.2) ]. Diarrhea Advise patients that diarrhea is a common problem caused by antibacterial drugs, including NUZYRA, which usually ends when the antibacterial drugs is discontinued.
Sometimes after starting treatment with antibacterial drugs, patients can develop watery or bloody stools (with or without stomach cramps and fever). If this occurs, patients should contact their physician as soon as possible. Tetracycline Class Adverse Reactions Inform patients that NUZYRA is similar to tetracycline class antibacterial drugs and may have similar adverse reactions [see Warnings and Precautions (5.5) ] .
Antibacterial Resistance Patients should be counseled that antibacterial drugs including NUZYRA should only be used to treat bacterial infections. They do not treat viral infections ( e.g. , the common cold). When NUZYRA 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 NUZYRA or other antibacterial drugs in the future.

14 CLINICAL STUDIES
14.1Community-Acquired Bacterial Pneumonia A total of 1444 adults with CABP were randomized in two multinational, double-blind, double-dummy trials (Trial 1 NCT02531438 and Trial 4 NCT04779242) comparing NUZYRA to moxifloxacin. NUZYRA was administered 100 mg intravenously every 12 hours for two doses on Day 1, followed by 100 mg intravenously daily, or 300 mg orally, daily. Moxifloxacin 400 mg was administered intravenously or orally daily.
Total treatment duration was 7-14 days. All enrolled patients were expected to require a minimum of at least 3 days of intravenous treatment. Efficacy and safety of an oral loading dose was not evaluated in CABP.
In Trial 1, a total of 386 patients were randomized to NUZYRA and 388 patients were randomized to moxifloxacin. Patient demographic and baseline characteristics were balanced between the treatment groups. Patients were predominantly male (55%) and white (92%).
Approximately 60% of patients in each group belonged to PORT Risk Class III, 26% were PORT Risk Class IV and 14.5% were PORT Risk Class II. The median age was 62 years, mean BMI was 27.34 kg/m2, and approximately 47% of NUZYRA treated patients had CrCl <90 ml/min. Among NUZYRA-treated patients, common comorbid conditions included hypertension (49.5%), diabetes mellitus (16.3%), chronic lung disease (21.2%), atrial fibrillation (10.1%), and coronary artery disease (9.1%).
The majority of sites were in Eastern Europe, which accounted for 82% of enrollment; 3 patients were enrolled in the US. In Trial 4, a total of 336 patients were randomized to NUZYRA and 334 patients were randomized to moxifloxacin. Patient demographic and baseline characteristics were balanced between the treatment groups.
Patients were predominantly male (51.6%) and white (99.7%). Approximately 76% of patients belonged to PORT Risk Class III, and 24% were PORT Risk Class IV. The median age was 65.0 years, mean BMI was 27.0 kg/m2, and approximately 56% of NUZYRA treated patients had CrCl <90 ml/min.
Among NUZYRA-treated patients, common comorbid conditions included hypertension (49.4%), diabetes mellitus (19.6%), chronic lung disease (11.9%), atrial fibrillation (6.5%), and coronary artery disease (1.2%). All sites were in Eastern Europe. Clinical success at the early clinical response (ECR) timepoint, 72 to 120 hours after the first dose, was defined as survival with improvement in at least two of four symptoms (cough, sputum production, chest pain, dyspnea) without deterioration in any of these four symptoms in the intent to treat population (ITT), which consisted of all randomized patients.

🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Carcinogenicity studies with omadacycline have not been conducted. However, there has been evidence of oncogenic activity in rats in studies with the related antibacterial drugs, oxytetracycline (adrenal and pituitary tumors), and minocycline (thyroid tumors). In a 9-month chronic toxicity study in monkeys, there were no observations of hyperplasia or neoplasia at doses up to 300 mg/kg/day (4-times the clinical AUC exposure).
Mutagenesis Omadacycline was positive for clastogenicity and aneugenicity in an in vitro chromosome aberration assay in Chinese hamster ovary (CHO) cells and for mutagenicity in an in vitro forward mutation assay in mouse lymphoma cells. These effects were seen in the presence of metabolizing enzymes. Omadacycline was negative in a chromosomal aberration test in Chinese hamster V79 cells and in vivo micronucleus assays administered intraperitoneally to ICR mice or intravenously to HanRcc: WIST rats.
Impairment of Fertility Omadacycline administration to male rats in a fertility study caused reduced sperm counts and sperm motility at 20-mg/kg/day (approximately 1.3 times clinical systemic exposure, based on AUC in a separate study in rats at a similar dose), but had no effect on male fertility parameters. In general toxicity studies, inhibition of spermatogenesis occurred after administration of 45-mg/kg/day omadacycline (6 to 8 times the clinical AUC exposure) for 37 days or longer, but not at lower doses (15-mg/kg/day, ≤ 2 times clinical AUC exposure) or shorter treatment periods (4 weeks or less).
In female rats, fertility was reduced at the 20-mg/kg/day dose (approximately equivalent to human exposures in a separate study in unmated females), characterized by reduced ovulation and increased embryonic loss when treatment occurred from before mating through early pregnancy.
13.2Animal Toxicology and/or Pharmacology In a 9-month study, omadacycline at oral doses of 30 to 300 mg/kg/day in monkeys (approximately 1-to 4-times the clinical AUC exposure) resulted in hyperpigmentation of lymphoid, reproductive, endocrine, including thyroid, and duodenum tissues. Hyperpigmentation of the thyroid has been produced by members of the tetracycline class in the following species: in rats by omadacycline, oxytetracycline, doxycycline, tetracycline PO4, and methacycline; in minipigs by doxycycline, minocycline, tetracycline PO4, and methacycline; in dogs by doxycycline and minocycline; in monkeys by omadacycline and minocycline.
Minocycline, tetracycline PO4, methacycline, doxycycline, tetracycline base, oxytetracycline HCl, and tetracycline HCl were goitrogenic in rats fed a low iodine diet. This goitrogenic effect was accompanied by high radioactive iodine uptake. Administration of minocycline also produced a large goiter with high radioiodine uptake in rats fed a relatively high iodine diet.
Treatment of various animal species with this class of drugs has also resulted in the induction of thyroid hyperplasia in the following: in rats and dogs (minocycline); in chickens (chlortetracycline); and in rats and mice (oxytetracycline). Adrenal gland hyperplasia has been observed in goats and rats treated with oxytetracycline.
📄 Carcinogenesis, Mutagenesis, Impairment of Fertility ▾
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Carcinogenicity studies with omadacycline have not been conducted. However, there has been evidence of oncogenic activity in rats in studies with the related antibacterial drugs, oxytetracycline (adrenal and pituitary tumors), and minocycline (thyroid tumors). In a 9-month chronic toxicity study in monkeys, there were no observations of hyperplasia or neoplasia at doses up to 300 mg/kg/day (4-times the clinical AUC exposure).
Mutagenesis Omadacycline was positive for clastogenicity and aneugenicity in an in vitro chromosome aberration assay in Chinese hamster ovary (CHO) cells and for mutagenicity in an in vitro forward mutation assay in mouse lymphoma cells. These effects were seen in the presence of metabolizing enzymes. Omadacycline was negative in a chromosomal aberration test in Chinese hamster V79 cells and in vivo micronucleus assays administered intraperitoneally to ICR mice or intravenously to HanRcc: WIST rats.
