INBRIJA

In the presence of carbidopa, the pharmacokinetics of levodopa are dose-proportional in healthy subjects taking up to 84 mg of INBRIJA. In the presence of carbidopa, the terminal elimination half-life (t 1/2 ) of levodopa following a single administration of INBRIJA 84 mg was 2.3 hours.

AbsorptionAfter a single dose of INBRIJA 84 mg (two 42 mg capsules), the median T max for plasma levodopa was approximately 0.5 hours (range 0.17–2.00 hours). In fasted healthy volunteers the bioavailability of ...

The efficacy and safety of INBRIJA for the treatment of OFF episodes in patients with Parkinson's disease treated with oral carbidopa/levodopa was evaluated in a 12-week, randomized, placebo-controlled, double-blind study (Study 1; NCT02240030).

Study 1In Study 1, a total of 114 patients were treated with INBRIJA 84 mg (two 42 mg capsules), and 112 patients received placebo. Study medication could be administered up to five times a day. At baseline, patients had at least 2 hours of OFF time per day, and carbidopa/levodopa medication did not exceed 1600 mg levodopa per day. The mean UPDRS Par...

INBRIJA is contraindicated in patients currently taking a nonselective monoamine oxidase (MAO) inhibitor (e.g., phenelzine and tranylcypromine) or who have recently (within 2 weeks) taken a nonselective MAO inhibitor. Hypertension can occur if these drugs are used concurrently [see Drug Interactions (7.1) ]. INBRIJA is contraindicated in patients currently taking a nonselective monoamine oxidase (...

May cause falling asleep during activities of daily living ( 5.1 ) Avoid sudden discontinuation or rapid dose reduction to reduce the risk of withdrawal-emergent hyperpyrexia and confusion ( 5.2 ) Hallucinations/exacerbation of psychosis may occur. Patients with a major psychotic disorder should not be treated with INBRIJA ( 5.3 , 7.2 ) Impulse Control Disorders: consider dose reduction or stopping INBRIJA ( 5.4 ) May cause or exacerbate dyskinesia: adjustment of levodopa therapy may be consider...
