Clinical
Triptorelin injection is used to treat certain types of prostate cancer. It is also used to treat central precocious puberty (CPP; a condition causing children to enter puberty too soon, resulting in faster than normal bone growth and development of sexual characteristics). Triptorelin injection is in a class of medications called gonadotropin-releasing hormone (GnRH) agonists. It works by decreasing the amount of certain hormones in the body.

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.

Full prescribing information FDA SPL
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE TRIPTODUR is indicated for the treatment of pediatric patients 2 years of age and older with central precocious puberty (CPP). TRIPTODUR is a gonadotropin releasing hormone (GnRH) agonist indicated for the treatment of pediatric patients 2 years and older with central precocious puberty. ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Must only be administered by a healthcare provider. ( 2.1 ) Administer TRIPTODUR as a single intramuscular injection of 22.5 mg once every 24 weeks. ( 2.1 ) Monitor response with LH levels after a GnRH or GnRH agonist stimulation test, basal LH, or serum concentration of sex steroid levels beginning 1 to 2 months following initiation of therapy, during therapy as necessary to confirm maintenance of efficacy, and with each subsequent dose.
( 2.2 ) Measure height every 3-6 months and monitor bone age periodically. ( 2.2 ) See FPI for complete reconstitution and administration instructions. ( 2.3 ) Once TRIPTODUR is mixed, proceed to the next steps and administer without delay.
( 2.3 ) The injection of the suspension should be performed rapidly and in a steady and uninterrupted manner in order to avoid any potential blockage of the needle. ( 2.3 )
2.1Dosing Information TRIPTODUR must only be administered by a healthcare provider. The dosage of TRIPTODUR is 22.5 mg reconstituted with accompanying diluent (Sterile Water) 2 mL, and administered as a single intramuscular injection once every 24 weeks. TRIPTODUR treatment should be discontinued at the appropriate age of onset of puberty at the discretion of the physician.
2.2Monitoring Monitor response to TRIPTODUR with LH levels after a GnRH or GnRH agonist stimulation test, basal LH, or serum concentration of sex steroid levels beginning 1 to 2 months following initiation of therapy, during therapy as necessary to confirm maintenance of efficacy, and with each subsequent dose. Measure height (for calculation of growth rate) every 3-6 months and monitor bone age periodically. Noncompliance with drug regimen or inadequate dosing may result in inadequate control of the pubertal process with gonadotropins and/or sex steroids increasing above prepubertal levels.
If the dose of TRIPTODUR is not adequate switching to an alternative GnRH agonist for the treatment of CPP with the ability for dose adjustment may be necessary.
2.3Reconstitution and Administration Instructions Read these instructions completely before you begin. • Triptodur suspension will sediment very quickly and should be injected immediately after reconstitution in accordance with the detailed instructions below. • If the sequence of steps to prepare the suspension is interrupted and/or the vial is put aside, the suspension will start to separate into diluent and microgranules. • To minimize the risk of needle blockage during the injection, ensure that the preparation of the injection is not interrupted and/or the mixed suspension syringe is not put aside because the suspension will sediment quickly.
1. Use appropriate aseptic technique for preparation and administration. 2.
Screw the plunger rod into the barrel end of the prefilled sterile water diluent syringe. 3. To remove the cap, twist counterclockwise to separate from the Luer lock on the syringe barrel.
4. Firmly attach one of the 21-gauge sterile safety needles onto the prefilled sterile water diluent syringe with a push and clockwise twist. This 21-gauge needle will only be used for reconstitution of the product. a.
Remove the plastic Flip-off from the vial. Disinfect the visible part of the stopper b. Pull back on the safety cover towards the syringe and away from the 21-gauge needle.
Then pull the clear needle shield off. 5. Insert the 21-gauge needle through the stopper.
Inject the Sterile Water diluent into the vial, ensuring the diluent rinses the sides of the vial. Do not release the plunger rod. 6.
If the syringe plunger is not maintained in position, it will naturally withdraw product into the syringe. Thoroughly mix the vial with agitation for 30 to 60 seconds, ensuring the diluent rinses the sides of the vial. 7.
Before moving on to the next step, check visually that the suspension appears milky and homogeneous without any visible aggregates or precipitates. a. If the suspension DOES NOT appear milky and homogeneous without…

⛔ Contraindications ▾
4 CONTRAINDICATIONS Hypersensitivity: TRIPTODUR is contraindicated in individuals with a known hypersensitivity to triptorelin, any other component of the product, or other GnRH agonists or GnRH [see Adverse Reactions (6.2) ] . Pregnancy: TRIPTODUR may cause fetal harm [see Use in Specific Populations (8.1) ] . Hypersensitivity reactions ( 4 ) Pregnancy ( 4 , 8.1 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Initial Rise of Gonadotropins and Sex Steroid Levels: An increase in clinical signs and symptoms of puberty may be observed during the first 2-4 weeks of therapy since gonadotropins and sex steroids rise above baseline because of the initial stimulatory effect of the drug. ( 5.1 ) Psychiatric events: Have been reported in patients taking GnRH agonists. Events include emotional lability, such as crying, irritability, impatience, anger, and aggression.
Monitor for development or worsening of psychiatric symptoms. ( 5.2 ) Convulsions: Have been observed in patients with or without a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and in patients on concomitant medications that have been associated with convulsions. ( 5.3 ) Severe Cutaneous Adverse Reactions (SCARs): Have been reported in patients receiving GnRH agonists, including triptorelin products.
Interrupt TRIPTODUR if signs or symptoms of SCARs develop. Permanently discontinue TRIPTODUR if a SCAR is confirmed. ( 5.4 ) Pseudotumor Cerebri (Idiopathic Intracranial Hypertension): Have been reported in pediatric patients receiving GnRH agonists, including triptorelin.
Monitor patients for headache, papilledema, and blurred vision. ( 5.5 )
5.1Initial Rise of Gonadotropins and Sex Steroid Levels During the early phase of initial therapy or after subsequent doses, gonadotropins and sex steroids may rise above baseline because of a transient stimulatory effect of the drug [see Clinical Pharmacology (12.2) ] . Therefore, a transient increase in clinical signs and symptoms of puberty, including vaginal bleeding, may be observed during the first weeks of therapy or after subsequent doses.
5.2Psychiatric Events Psychiatric events have been reported in patients taking GnRH agonists, including triptorelin. Post-marketing reports with this class of drugs include symptoms of emotional lability, such as crying, irritability, impatience, anger, and aggression. Monitor for development or worsening of psychiatric symptoms during treatment with TRIPTODUR [see Adverse Reactions (6) ] .
5.3Convulsions Post-marketing reports of convulsions have been observed in patients receiving GnRH agonists, including triptorelin. These included patients with a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and patients on concomitant medications that have been associated with convulsions such as bupropion and SSRIs. Convulsions have also been reported in patients in the absence of any of the conditions mentioned above [ see Adverse Reactions (6) ].
5.4Severe Cutaneous Adverse Reactions (SCARs) Severe cutaneous adverse reactions (SCARs) have been reported in patients receiving GnRH agonists, including triptorelin products [see Adverse Reactions ( 6.2 )] . These reactions include Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), including cases with visceral involvement and/or requiring skin grafts. Monitor patients for signs and symptoms of SCARs such as fever, flu-like symptoms, mucosal lesions, progressive skin rash or lymphadenopathy.
Advise patients and caregivers of the signs and symptoms of SCARs. If a SCAR is suspected, interrupt TRIPTODUR. Consult a healthcare provider with expertise in the diagnosis and management of SCARS.
If a diagnosis is confirmed permanently discontinue TRIPTODUR.
5.5Pseudotumor Cerebri (Idiopathic Intracranial Hypertension) Pseudotumor cerebri (idiopathic intracranial hypertension) has been reported in pediatric patients receiving GnRH agonists, including triptorelin. Monitor patients for signs and symptoms of pseudotumor cerebri, including headache, papilledema, blurred vision, diplopia, loss of vision, pain behind the eye or pain with eye movement, tinnitus, dizziness, and nausea.

6 ADVERSE REACTIONS The following serious adverse reactions are described here and elsewhere in the label: Initial Rise of Gonadotropins and Sex Steroid Levels [ see Warnings and Precautions ( 5.1 ) ] Psychiatric Events [ see Warnings and Precautions ( 5.2 ) ] Convulsions [ see Warnings and Precautions ( 5.3 ) ] Severe Cutaneous Adverse Reactions [ see Warnings and Precautions ( 5.4 ) ] Pseudotumor Cerebri (Idiopathic Intracranial Hypertension) [ see Warnings and Precautions ( 5.5 ) ] In clinical trials for TRIPTODUR, the most common adverse reactions (≥4.5%) are injection site reactions, menstrual (vaginal) bleeding, hot flush, headache, cough, and infections (bronchitis, gastroenteritis, influenza, nasopharyngitis, otitis externa, pharyngitis, sinusitis, and upper respiratory tract infection).
( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Azurity Pharmaceuticals, Inc. at 1-800-461-7449 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
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. The safety of TRIPTODUR was evaluated in one uncontrolled, open-label single-arm clinical trial in which 44 children with central precocious puberty received two doses of TRIPTODUR and were observed for 12 months. The median age of the study population was 8 years (range 2-9 years) at treatment start; 88.6% of subjects were female, 59.1% were White, 27.3% were Black and 4.5% were Asian.
Table 1 shows all the adverse reactions that occurred in at least 2 patients (≥4.5%) during the open-label single-arm trial. Table 1: Adverse Reactions1 Occurring in ≥ 2 Patients Treated with TRIPTODUR in an Open-Label Single-Arm Trial Adverse Reactions Number of Patients Reporting Event (%) (Total N=44) Infections & Infestations Bronchitis 2 (4.5) Gastroenteritis 3 (6.8) Influenza 2 (4.5) Nasopharyngitis 6 (13.6) Otitis externa 2 (4.5) Pharyngitis 2 (4.5) Sinusitis 2 (4.5) Upper respiratory tract infection 4 (9.1) Nervous System Disorders Headache 6 (13.6) Reproductive System & Breast Disorders Menstrual (Vaginal bleeding) 2 3 (7.7) Respiratory, Thoracic & Mediastinal Disorder Cough 3 (6.8) Vascular Disorders Hot flush 2 (4.5) 1 Injection site reactions are presented separately 2 Includes % of patients with vaginal bleeding or menstrual disorder (“menstrual cycle returned”) in 39 females out of N=44.
Other Selected Adverse Reactions: Injection Site Reactions Injection site reactions occurring in patients immediately and/or 2 hours after injection include pain (45%), redness (14%), pruritus (2.3%) and swelling (2.3%). Psychiatric Disorders Anxiety (2.3%) and mood altered (2.3%)
6.2Post-marketing Experience The following adverse reactions have been identified during post-approval use of triptorelin or GnRH agonists. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Hypersensitivity Reactions: Anaphylactic shock, anaphylactoid reaction, angioedema, urticaria.
Cardiovascular: Hypertension. Psychiatric: Emotional lability, such as crying, irritability, impatience, anger, and aggression . Depression, including rare reports of suicidal ideation and attempt.
Many, but not all, of these patients had a history of psychiatric illness or other comorbidities with an increased risk of depression. Nervous System: Convulsions , pseudotumor cerebri (idiopathic intracranial hypertension) Vision Disorders: Visual impairment, visual disturbance Skin Reactions: erythema multiforme, bullous dermatitis, dermatitis exfoliative, drug reaction with eosinophilia and systemic symptoms, Stevens-Johnson syndrome and toxic epidermal necrolysis, and acute generalized exanthematous pustulosis
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS
7.1Drug-Drug Interactions Results of in vitro studies show that drug-drug interactions with triptorelin are unlikely [see Clinical Pharmacology (12.3)] . However, in the absence of relevant data and as a precaution, hyperprolactinemic drugs should not be used concomitantly with triptorelin since hyperprolactinemia reduces the number of pituitary GnRH receptors.
7.2Drug-Laboratory Test Interactions Administration of TRIPTODUR results in suppression of the pituitary-gonadal system. The effect of TRIPTODUR on pituitary and gonadal function is expected to disappear within six to twelve months after treatment discontinuation. Therefore, diagnostic tests of pituitary gonadotropic and gonadal functions conducted during treatment or after discontinuation of treatment may be affected.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary TRIPTODUR is contraindicated in women who are pregnant [ see Contraindications ( 4 ) ] since expected hormonal changes that occur with TRIPTODUR treatment increase the risk for pregnancy loss. Available data with triptorelin use in pregnant women are insufficient to determine a drug-associated risk of adverse developmental outcomes. Based on mechanism of action in humans and findings of increased pregnancy loss in animal studies, TRIPTODUR may cause fetal harm when administered to pregnant women.
Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% - 4% and 15% -20%, respectively.
Data Animal Data In pregnant rats administered triptorelin at doses of 2, 10, and 100 mcg/kg/day during the period of organogenesis, maternal toxicity (decrease in body weight) and embryo-fetal toxicities (pre-implantation loss, increased resorption, and reduced number of viable fetuses) were observed at 100 mcg/kg, approximately 4 times the clinical dose based on body surface area. No embryonic and fetal developmental toxicities were observed in mice at doses up to 4 times the clinical dose. Teratogenic effects were not observed in viable fetuses in rats or mice.
8.2Lactation Risk Summary There are no data on the presence of triptorelin in human milk, or the effects of the drug on the breastfed infant, or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TRIPTODUR and any potential adverse effects on the breastfed child from TRIPTODUR or from the underlying maternal condition
8.6Renal Impairment TRIPTODUR has not been studied in children with renal impairment. Adult subjects with renal impairment had higher exposure than young healthy adult males [see Clinical Pharmacology (12.3) ].
8.4Pediatric Use The safety and effectiveness of TRIPTODUR have been established in pediatric patients 2 years of age and older based on a single-arm open-label study of 44 children 2-9 years of age with CPP [see Clinical Studies (14) ] . The safety and effectiveness of TRIPTODUR have not been established in pediatric patients less than 2 years old.
8.7Hepatic Impairment TRIPTODUR has not been studied in children with hepatic impairment. Adult subjects with hepatic impairment had higher exposure than young healthy adult males [see Clinical Pharmacology (12.3) ].

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Triptorelin is a GnRH agonist.
12.2Pharmacodynamics Following the first administration, there is a transient surge in circulating levels of LH, FSH, testosterone, and estradiol [see Warnings and Precautions (5.2) ] . After chronic and continuous administration, by 4 weeks after initiation of therapy, a sustained decrease in LH and FSH secretion and marked reduction in sex steroids are observed.
12.3Pharmacokinetics Absorption After an initial intramuscular TRIPTODUR 22.5 mg injection and a second 22.5 mg intramuscular injection 24 weeks later in children 2 to 9 years old with CPP, triptorelin peaked 4 hours postdose with a geometric mean C max of 39.9 and 36.5 ng/mL, respectively. No apparent accumulation of triptorelin occurred after the second injection. Absorption occurred in two phases, a burst phase followed by a maintenance release phase.
In children with CPP, following the burst phase after the first 22.5 mg injection, geometric mean serum triptorelin levels were 0.11, 0.17, 0.05 and 0.03 ng/mL at Months 1, 2, 3, and 6, respectively. Distribution There is no evidence that triptorelin, at clinically relevant concentrations, binds to plasma proteins. Elimination Metabolism The metabolism of triptorelin in humans is unknown, but is unlikely to involve hepatic microsomal enzymes (cytochrome P450).
Thus far no metabolites of triptorelin have been identified. Pharmacokinetic data suggest that C-terminal fragments produced by tissue degradation are either completely degraded in the tissues, or rapidly degraded in plasma, or cleared by the kidneys. Excretion Triptorelin is eliminated by both the liver and the kidneys.
Following intravenous administration of 0.5 mg triptorelin peptide to six healthy male volunteers with a creatinine clearance of 149.9 mL/min, 41.7% of the dose was excreted in urine as intact peptide with a total triptorelin clearance of 211.9 mL/min. This percentage increased to 62.3% in patients with liver disease who have a lower creatinine clearance (89.9 mL/min). It has also been observed that the nonrenal clearance of triptorelin (patient anuric, Cl creat = 0) was 76.2 mL/min, thus indicating that the nonrenal elimination of triptorelin is mainly dependent on the liver.
Specific Populations Renal Impairment After intravenous bolus injection of 0.5 mg triptorelin in adults, the two distribution half-lives were unaffected by renal impairment. However, renal insufficiency led to a decrease in total triptorelin clearance proportional to the decrease in creatinine clearance as well as increases in volume of distribution and consequently, an increase in the elimination half-life. Adult male subjects with moderate or severe renal impairment had approximately 2-fold higher exposure (AUC values) than young healthy adult males (see Table 1) [ see Use in Specific Populations ( 8.6 ) ].
Hepatic Impairment After intravenous bolus injection of 0.5 mg triptorelin in adults, the two distribution half-lives were unaffected by hepatic impairment.
