INVEGA SUSTENNA

Absorption and

DistributionDue to its extremely low water solubility, the 1-month formulation of paliperidone palmitate dissolves slowly after intramuscular injection before being hydrolyzed to paliperidone and absorbed into the systemic circulation. Following a single intramuscular dose, the plasma concentrations of paliperidone gradually rise to reach maximum plasma concentrations at a median T max of 13 days. The release of the drug starts as early as day 1 and lasts for as long as 126 days....

14.1 Schizophrenia Short-Term Monotherapy (Studies 1, 2, 3, 4) The efficacy of INVEGA SUSTENNA in the acute treatment of schizophrenia was evaluated in four short-term (one 9-week and three 13-week) double-blind, randomized, placebo-controlled, fixed-dose studies of acutely relapsed adult inpatients who met DSM-IV criteria for schizophrenia.

Efficac...
