Abstract
A sustained release dosage form includes a capsule made of a thermoplastic polymer having a softening point below 200° C. and an orifice formed or formable within the capsule, an emulsion formulation contained within the capsule, and an expandable composition within the capsule remote from the orifice. The emulsion formulation comprises a drug, an emulsifying surfactant, and an oil. The expandable composition is configured to expand and expel the emulsion formulation through the orifice.
Claims17
A sustained release dosage form, comprising:
- a capsule made of a thermoplastic polymer composition having a softening point below 200° C. and an orifice formed or formable within the capsule wherein the capsule contains components consisting essentially of:
- (a) a self-emulsifying formulation contained within a first portion of the capsule in contact with the orifice, the formulation comprising a drug, an emulsifying surfactant, and an oil;
- and
- (b) in an expandable composition contained within a second portion of the capsule separated from the orifice, by the self-emulsifying formulation of (a),
- wherein there is no layer separating the self-emulsifying formulation from the expandable composition,
- wherein the expandable composition is configured to expand and expel the self-emulsifying formulation through the orifice.
