Disclosed is a pharmaceutical composition for extended release of an erythromycin derivative in the gastrointestinal environment. The composition comprises an erythromycin derivative and a pharmaceutically acceptable polymer so that, when ingested orally, the composition induces statistically significantly lower Cmax in the plasma than an immediate release composition of the erythromycin derivative while maintaining bioavailability and minimum concentration substantially equivalent to that of the immediate release composition of the erythromycin derivative upon multiple dosing. The compositions of the invention have an improved taste profile and reduced gastrointestinal side effects as compared to those for the immediate release composition.

Tranexamic acid formulated in an oral dosage form with at least one agent that decreases tranexamic acid release in the stomach. Such formulations minimize nausea, vomiting, and other adverse gastric effects that may accompany tranexamic acid therapy, for example, to treat heavy menstrual bleeding. One embodiment is an extended release formulation with waxes, polymers, etc. that prevent a bolus release of tranexamic acid in the stomach. An alternative embodiment is a delayed release formulation with polymers that prevent release of tranexamic acid in the acid environment of the stomach and delay its release until the formulation reaches the less acid environment of the intestines. Such formulations enhance patient compliance with therapy because adverse effects of tranexamic acid therapy are reduced.

The present invention relates, in part, to the discovery that a pharmaceutical composition comprising aripiprazole and a carrier administered in a bolus injection resulted in an extended release profile similar to that obtained by the injection of a poly lactide-co-glycolide microsphere formulation containing the active agent. This surprising result suggests that pharmacologically beneficial extended release formulations without the complexities and expense associated with the manufacture microspheres.
