Following a single oral dose of 150 mg/m 2 , the mean C max value for temozolomide was 7.5 mcg/mL and for MTIC was 282 ng/mL. The mean AUC value for temozolomide was 23.4 mcg·hr/mL and for MTIC was 864 ng·hr/mL. Temozolomide exhibits linear kinetics over the therapeutic dosing range of 75 mg/m 2 /day to 250 mg/m 2 /day.

AbsorptionThe median T max is 1 hour. Effect of Food The mean C max and AUC decreased by 32% and 9%, respectively, and median T max increased by 2-fold (from 1-2.25 hours) when ...

14.1 Newly Diagnosed Glioblastoma The efficacy of Temozolomide was evaluated in Study MK-7365-051, a randomized (1:1), multicenter, open-label trial. Eligible patients were required to have newly diagnosed glioblastoma. Patients were randomized to receive either radiation therapy alone or concomitant Temozolomide 75 mg/m 2 once daily starting the first day of radiation therapy and continuing until the last day of radiation therapy for 42 days (with a maximum of 49 days), followed by Temozolomide 150 mg/m 2 or 200 mg/m 2 once daily on Days 1 to 5 of each 28-day cycle, starting 4 weeks after the...

Temozolomide capsules, USP is contraindicated in patients with a history of hypersensitivity reactions to: temozolomide or any other ingredients in Temozolomide capsules, USP; and dacarbazine, since both temozolomide and dacarbazine are metabolized to the same active metabolite 5-(3­-methyltriazen-1-yl)-imidazole-4-carboxamide. Reactions to Temozolomide have included anaphylaxis [see Adverse React...

Myelosuppression : Monitor absolute neutrophil count (ANC) and platelet count prior to each cycle and during treatment. Geriatric patients and women have a higher risk of developing myelosuppression. ( 5.1 ) Myelodysplastic Syndrome and Secondary Malignancies , including myeloid leukemia, have been observed. ( 5.2 ) Pneumocystis P neumonia (PCP): Closely monitor all patients, particularly those receiving steroids, for the development of lymphopenia and PCP. ( 5.3 ) Hepatotoxicity: Fatal and seve...
