🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

A current SPL was checked, but it does not contain a structured or narrative inactive-ingredient list for this product. This does not mean the product has no inactive ingredients.
Where does this data come from?
Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

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.

📊 Medicare Part D spend CMS · PART D · 2025 (Q1-Q4)

Medicare Part D (outpatient prescription) spending for Leuprolide Acetate — the program that covers self-administered drugs. 2 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 Leuprolide Acetate. 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.

🎯 Indications and Usage 16 words

INDICATIONS AND USAGE Leuprolide acetate injection is indicated in the palliative treatment of advanced prostatic cancer.

⏱️ Dosage and Administration 107 words

DOSAGE AND ADMINISTRATION The recommended dose is 1 mg (0.2 mL or 20 unit mark) administered as a single daily subcutaneous injection. As with other drugs administered chronically by subcutaneous injection, the injection site should be varied periodically. Each 0.2 mL contains 1 mg of leuprolide acetate, sodium chloride for tonicity adjustment, 1.8 mg of benzyl alcohol as preservative and water for injection.

The pH may have been adjusted with sodium hydroxide and/or glacial acetic acid. Follow the pictorial directions on the reverse side of this package insert for administration. NOTE: As with all parenteral products, inspect the solution for discoloration and particulate matter before each use.

Contraindications 41 words

CONTRAINDICATIONS Leuprolide acetate injection is contraindicated in patients known to be hypersensitive to GnRH, GnRH agonist analogs or any of the excipients in leuprolide acetate injection: Reports of anaphylactic reactions to GnRH agonist analogs have been reported in the medical literature.

⚠️ Warnings ~1 min read

WARNINGS Initially, leuprolide acetate injection, like other LH-RH agonists, causes increases in serum levels of testosterone. Transient worsening of symptoms, or the occurrence of additional signs and symptoms of prostate cancer, may develop during the first few weeks of leuprolide acetate injection treatment. Patients may experience a temporary increase in bone pain, which can be managed symptomatically.

As with other LH-RH agonists, ureteral obstruction and spinal cord compression have been observed, which may contribute to paralysis with or without fatal complications. Safe use of leuprolide acetate in pregnancy has not been established clinically. Leuprolide acetate injection may cause fetal harm.

Periodic monitoring of serum testosterone and prostate-specific antigen (PSA) levels is recommended, especially if the anticipated clinical or biochemical response to treatment has not been achieved. It should be noted that results of testosterone determinations are dependent on assay methodology. It is advisable to be aware of the type and precision of the assay methodology to make appropriate clinical and therapeutic decisions.

Severe Cutaneous Adverse Reactions Leuprolide acetate can cause severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). SCARs, including SJS/TEN, DRESS, and AGEP, occurred in patients receiving leuprolide acetate; including cases with visceral involvement and/or requiring skin grafts [see Adverse Reactions ]. Monitor patients for the development of SCARs.

If a SCAR is suspected, interrupt leuprolide acetate until the etiology of the reaction has been determined. Consultation with a dermatologist is recommended. If a SCAR is confirmed, or for other grade 4 skin reactions, permanently discontinue leuprolide acetate.

🤒 Adverse Reactions ~2 min read

ADVERSE REACTIONS Clinical Trials In the majority of patients testosterone levels increased above baseline during the first week, declining thereafter to baseline levels or below by the end of the second week of treatment. This transient increase was occasionally associated with a temporary worsening of signs and symptoms, usually manifested by an increase in bone pain (see WARNINGS section). Cases of temporary worsening of existing hematuria and urinary tract obstruction have occurred during the first week.

Temporary weakness and paresthesia of the lower limbs have been reported. Potential exacerbations of signs and symptoms during the first few weeks of treatment is a concern in patients with vertebral metastases and/or urinary obstruction which, if aggravated, may lead to neurological problems or increase the obstruction. In a comparative trial of leuprolide acetate injection versus DES, in 5% or more of the patients receiving either drug, the following adverse reactions were reported to have a possible or probable relationship to drug as ascribed by the treating physician.

Often, causality is difficult to assess in patients with metastatic prostate cancer. Reactions considered not drug related are excluded.

Drug/Laboratory Test Interactions Administration of leuprolide acetate in therapeutic doses results in suppression of the pituitary-gonadal system. Normal function is usually restored within 4 to 12 weeks after treatment is discontinued.

🤰 Pregnancy ~1 min read

Pregnancy Risk Summary Based on findings in animal studies and mechanism of action, leuprolide acetate injection may cause fetal harm when administered to a pregnant woman. There are no available data in pregnant women to inform the drug-associated risk. In animal developmental and reproductive toxicology studies, administration of a monthly formulation of leuprolide acetate on day 6 of pregnancy (sustained exposure was expected throughout the period of organogenesis) caused adverse embryo-fetal toxicity in animals at doses less than the human dose based on body surface area using an estimated daily dose (see data) .

Advise pregnant patients and females of reproductive potential of the potential risk to the fetus. Data Animal Data Major fetal malformations were observed in developmental and reproductive toxicology studies in rabbits after a single administration of the monthly formulation of leuprolide acetate administered on day 6 of pregnancy at test dosages of 0.00024, 0.0024, and 0.024 mg/kg (approximately 1/600 to 1/6 the human dose based on body surface area using an estimated daily dose in animals and humans). Since a depot formulation was utilized in the study, a sustained exposure to leuprolide was expected throughout the period of organogenesis and to the end of gestation.

Similar studies in rats did not demonstrate an increase in fetal malformations, however, there was increased fetal mortality and decreased fetal weights with the two higher doses of the monthly formulation of leuprolide acetate in rabbits and with the highest dose in rats.

🧓 Geriatric Use 39 words

Geriatric Use In the clinical trials for leuprolide acetate injection, the majority (69%) of subjects studied were at least 65 years of age. Therefore, the labeling reflects the pharmacokinetics, efficacy and safety of leuprolide acetate injection in this population.

🆘 Overdosage 79 words

OVERDOSAGE In rats subcutaneous administration of 250 to 500 times the recommended human dose, expressed on a per body weight basis, resulted in dyspnea, decreased activity, and local irritation at the injection site. There is no evidence at present that there is a clinical counterpart of this phenomenon. In early clinical trials with leuprolide acetate doses as high as 20 mg/day for up to two years caused no adverse effects differing from those observed with the 1 mg/day dose.

🧬 Clinical Pharmacology ~2 min read

CLINICAL PHARMACOLOGY Leuprolide acetate, a GnRH agonist, acts as an inhibitor of gonadotropin secretion. Animal studies indicate that following an initial stimulation, continuous administration of leuprolide acetate results in suppression of ovarian and testicular steroidogenesis. This effect was reversible upon discontinuation of drug therapy.

Administration of leuprolide acetate has resulted in inhibition of the growth of certain hormone dependent tumors (prostatic tumors in Noble and Dunning male rats and DMBA-induced mammary tumors in female rats) as well as atrophy of the reproductive organs. In humans, subcutaneous administration of single daily doses of leuprolide acetate results in an initial increase in circulating levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH), leading to a transient increase in levels of the gonadal steroids (testosterone and dihydrotestosterone in males, and estrone and estradiol in pre-menopausal females).

However, continuous daily administration of leuprolide acetate results in decreased levels of LH and FSH. In males, testosterone is reduced to castrate levels. In pre-menopausal females, estrogens are reduced to post-menopausal levels.

These decreases occur within two to four weeks after initiation of treatment, and castrate levels of testosterone in prostatic cancer patients have been demonstrated for periods of up to five years. Leuprolide acetate is not active when given orally. Pharmacokinetics Absorption Bioavailability by subcutaneous administration is comparable to that by intravenous administration.

Distribution The mean steady-state volume of distribution of leuprolide following intravenous bolus administration to healthy male volunteers was 27 L. In vitro binding to human plasma proteins ranged from 43% to 49%. Metabolism In healthy male volunteers, a 1 mg bolus of leuprolide administered intravenously revealed that the mean systemic clearance was

7.6L/h, with a terminal elimination half-life of approximately 3 hours based on a two compartment model. In rats and dogs, administration of 14 C-labeled leuprolide was shown to be metabolized to smaller inactive peptides, a pentapeptide (Metabolite I), tripeptides (Metabolites II and III) and a dipeptide (Metabolite IV). These fragments may be further catabolized.

The major metabolite (M-I) plasma concentrations measured in 5 prostate cancer patients reached maximum concentration 2 to 6 hours after dosing and were approximately 6% of the peak parent drug concentration. One week after dosing, mean plasma M-I concentrations were approximately 20% of mean leuprolide concentrations. Excretion Following administration of leuprolide acetate for depot suspension, 3.75 mg to 3 patients, less than 5% of the dose was recovered as parent and M-I metabolite in the urine.

Special Populations The pharmacokinetics of the drug in hepatically and renally impaired patients has not been determined. Drug Interactions No pharmacokinetic-based drug-drug interaction studies have been conducted with leuprolide acetate. However, because leuprolide acetate is a peptide that is primarily degraded by peptidase and not by cytochrome P-450 enzymes as noted in specific studies, and the drug is only about 46% bound to plasma proteins, drug interactions would not be expected to occur.

CLINICAL STUDIES In a controlled study comparing leuprolide acetate injection 1 mg/day given subcutaneously to DES (diethylstilbestrol), 3 mg/day, the survival rate for the two groups was comparable after two years of treatment. The objective response to treatment was also similar for the two groups.

DESCRIPTION Leuprolide acetate is a synthetic nonapeptide analog of naturally occurring gonadotropin releasing hormone (GnRH or LH-RH). The analog possesses greater potency than the natural hormone. The chemical name is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-D-­leucyl-L-leucyl-L-arginyl-N-ethyl-L-prolinamide acetate (salt) with the following structural formula: Leuprolide acetate injection is a sterile, aqueous clear colorless solution intended for subcutaneous injection.

It is available in a 2.8 mL multiple-dose vial containing leuprolide acetate, USP (5 mg/mL), sodium chloride, USP (6.3 mg/mL) for tonicity adjustment, benzyl alcohol, NF as a preservative (9 mg/mL), and water for injection, USP. The pH may have been adjusted with sodium hydroxide, NF and/or glacial acetic acid, USP. The pH range is 4.0 to 6.0.

INFORMATION FOR PATIENTS Be sure to consult your physician with any questions you may have or for information about leuprolide acetate injection and its use. WHAT IS LEUPROLIDE ACETATE INJECTION? Leuprolide acetate injection is chemically similar to gonadotropin releasing hormone (GnRH or LH-RH) a hormone which occurs naturally in your body.

Normally, your body releases small amounts of LH-RH and this leads to events which stimulate the production of sex hormones. However, when you inject leuprolide acetate injection, the normal events that lead to sex hormone production are interrupted and testosterone is no longer produced by the testes. Leuprolide acetate injection must be injected because, like insulin which is injected by diabetics, leuprolide acetate is inactive when taken by mouth.

If you were to discontinue the drug for any reason, your body would begin making testosterone again. DIRECTIONS FOR USING LEUPROLIDE ACETATE INJECTION Wash hands thoroughly with soap and water. When using a new vial of leuprolide acetate injection, flip off the plastic cover to expose the grey rubber stopper.

Wipe metal ring and rubber stopper with an alcohol wipe each time you use leuprolide acetate injection. Check the liquid in the vial for particulate matter and discoloration prior to use. DO NOT USE if the liquid is not clear or has particles and replace with a new vial.

Remove needle cap and inject the needle in the center of the rubber stopper on the leuprolide acetate injection vial. Take cover off needle. Push the needle through the center of the rubber stopper on the leuprolide acetate injection vial.

Push the plunger all the way in to inject air into the vial. Keep the needle in the vial and turn the vial upside down. Check to make sure the tip of the needle is in the liquid.

Slowly pull back on the plunger, until the syringe fills to the 0.2 mL or 20 unit mark. Toward the end of a two-week period, the amount of leuprolide acetate injection left in the vial will be small. Take special care to hold the vial straight and to keep the needle tip in liquid while pulling back on the plunger.

Keeping the needle in the vial and the vial upside down, check for air bubbles in the syringe. If you see any, push the plunger slowly in to push the air bubble back into the vial. Keep the tip of the needle in the liquid and pull the plunger back again to fill to the 0.2 mL or 20 unit mark.

Do this again if necessary to eliminate air bubbles. To protect your skin, inject each daily dose at a different injection site. Choose an injection site.

Cleanse the injection site with another alcohol wipe. Hold the syringe in one hand. Hold the skin taut, or pull up a little flesh with the other hand, as you were instructed.

Holding the syringe as you would a pencil, inject the needle all the way into the skin at a 90° angle. Push the plunger to administer the injection. Hold an alcohol wipe down on your skin where the needle is inserted and withdraw the needle at the same angle it was inserted.

Use the disposable syringe only once and dispose of it properly as you were instructed. Needles thrown into a garbage bag could accidentally stick someone. NEVER LEAVE SYRINGES, NEEDLES OR DRUGS WHERE CHILDREN CAN REACH THEM.

SOME SPECIAL ADVICE You may experience hot flashes when using leuprolide acetate injection. During the first few weeks of treatment you may experience increased bone pain, increased difficulty in urinating, and less commonly but most importantly, you may experience the onset or aggravation of nerve symptoms. In any of these events, discuss the symptoms with your doctor.

Like other treatment options, leuprolide acetate injection may cause impotence. Notify your doctor if you develop new or worsened symptoms after beginning leuprolide acetate injection treatment. You may experience some irritation at the injection site, such as burning, itching or swell…
