TRIPTODUR KIT

Results of pharmacokinetic investigations conducted in healthy men indicate that after intravenous bolus administration, triptorelin is distributed and eliminated according to a 3-compartment model and corresponding half-lives are approximately 6 minutes, 45 minutes, and 3 hours.

AbsorptionFollowing a single intramuscular injection of TRELSTAR to patients with prostate cancer, mean peak serum concentrations of 28.4 ng/mL, 38.5 ng/mL, and 44.1 ng/mL occurred in 1 to 3 hours after the 3.75 mg, 11...

TRELSTAR 3.75 mg TRELSTAR 3.75 mg was studied in a randomized, active control trial of 277 men with advanced prostate cancer. The clinical trial population consisted of 59.9% Caucasian, 39.3% Black, and 0.8% Other. There was no difference observed with triptorelin response between racial groups. Men were between 47 and 89 years of age (mean = 71 years). Patients received either TRELSTAR 3.75 mg (N = 140) or an approved GnRH agonist monthly for 9 months. The primary efficacy endpoints were both achievement of castration by Day 29 and maintenance of castration from Day 57 through Day 253. Castra...

Known hypersensitivity to triptorelin or any other component of the product, or other GnRH agonists or GnRH. ( 4 ) 4.1 Hypersensitivity TRELSTAR is contraindicated in individuals with a known hypersensitivity to triptorelin or any other component of the product, or other GnRH agonists or GnRH [see Warnings and Precautions (5.1) ].

Hypersensitivity: Anaphylactic shock, hypersensitivity, and angioedema have been reported. In the event of a reaction, discontinue TRELSTAR and initiate appropriate medical management. ( 5.1 ) Tumor Flare: Transient increase in serum testosterone levels can occur within the first few weeks of treatment. This may worsen prostate cancer and result in spinal cord compression and urinary tract obstruction. Monitor patients at risk and manage as appropriate. ( 5.2 ) Metabolic Syndrome: The use of GnR...

7 DRUG INTERACTIONS No drug-drug interaction studies involving TRELSTAR have been conducted. Human pharmacokinetic data with triptorelin suggest that C-terminal fragments produced by tissue degradation are either degraded completely within tissues, are rapidly degraded further in plasma, or cleared by the kidneys. Therefore, hepatic microsomal enzymes are unlikely to be involved in triptorelin met...
