摘要：
A carrier formulation for controlled release of injectable drugs is disclosed. The formulation comprises a pharmaceutical active agent, a high viscosity liquid carrier material (HVLCM) like sucrose acetate isobutyrate, a lactic acid-based polymer like poly(lactic acid)(glycolic acid), and an organic solvent which maintains the composition in a monophasic form at 25°C in one atmosphere. The drug is released upon administration such that less than 10% (e.g. 2-8%) of drug is released in the first 5 hours 10% to 80% of the drug is released during a period of 5 hours to 7 days after administration and 10% to 40% of the drug is released gradually over a period of 7 days to 28 days from initial administration. The drug may be an anti- schizophrenia agent delivered by injection.
