The present invention is directed to methods of treating psychiatric diseases and disorders comprising administering to a subject in need thereof an injectable formulation comprising risperidone, triblock and diblock copolymers wherein the concentration of the risperidone is 250-400 mg/mL and injection volume is 1 mL or less.

Drug delivery formulations

The present invention provides a biodegradable drug delivery composition comprising: (i) a mixture of at least three different block copolymers, wherein each block copolymer is: (a) a biodegradable triblock copolymer having the formula: A-B-Awherein A is a polyester and B is polyethylene glycol and v and x are the number of repeat units from 1 to 3,000 and w is the number of repeat units from 3 to 300 and v=x or v&#x2260;x; or (b) a biodegradable diblock copolymer having the formula: C-Awherein A is a polyester and C is an end-capped polyethylene glycol and y and z are the number of repeat units with y=2 to 250 and z=1 to 3,000; and wherein the mixture comprises at least one (a) and at least one (b); and the weight ratio between (a) and (b) is 1:19 to 5:1; and (ii) at least one pharmaceutically active ingredient.

Biodegradable block copolymer drug delivery composition

Provided is a biodegradable drug delivery composition comprising: (i) a mixture of at least three different block copolymers, wherein each block copolymer is: (a) a biodegradable triblock copolymer having the formula: A-B-Awherein A is a polyester and B is polyethylene glycol and v and x are from 1 to 3,000 and w is from 3 to 300 and v=x or v&#x2260;x; or (b) a biodegradable diblock copolymer having the formula: C-Awherein A is a polyester and C is an end-capped polyethylene glycol and y=2 to 250 and z=1 to 3,000; and wherein the mixture comprises at least one (a) and at least one (b); and the weight ratio between (a) and (b) is 1:19 to 5:1; and for at least one of the copolymers according to (a) or (b) A is poly(lactic-co-glycolic acid) (PLGA); and (ii) at least one pharmaceutically active ingredient.

The present invention provides a biodegradable drug delivery composition comprising a mixture of at least two block copolymers taken among triblock and diblock copolymers comprising: (a) a biodegradable triblock copolymer having the formula: A-B-Awherein A is a polyester and B is polyethylene glycol and v and x are from 1 to 3,000 and w is from 3 to 300 and v=x or v&#x2260;x; (b) a biodegradable diblock copolymer having the formula: C-Awherein A is a polyester and C is an end-capped polyethylene glycol and y and z are the number of repeat units with y=2 to 250 and z=1 to 3,000; wherein the weight ratio between (a) and (b) is 1:19 to 5:1; and for at least one of the copolymers according to (a) or (b) A is poly(&#x3b5;-caprolactone-co-lactide); and (c) at least one pharmaceutically active ingredient.
