Reconstitutable teverelix-TFA composition
11633453 · 2023-04-25 · ·

The present invention relates to a reconstitutable teverelix-TFA composition having a predefined molar ratio of teverelix to trifluoroacetate which is below the molar ratio required for microcrystal formation. Said composition remains stable during storage e.g. at a temperature around 2-8° C. Upon reconstitution a fixed amount of trifluoroacetate can be added to said composition thereby effectively and simply achieving an exact and desired molar ratio in order to obtain a fluid, milky microcrystalline aqueous teverelix-TFA suspension.

Method for preparing biodegradable microspheres using stabilized single-phase mixed solution

The present invention relates to a method for preparing biodegradable microspheres using a single-phase mixed solution containing water, alcohol, and dichloromethane. Provided is a method for preparing a biodegradable microsphere having a uniform drug loading efficiency by preparing and using a single-phase mixed solution in which no phase separation occurs without using a thickener and a surfactant. The preparation method of the present invention has the feature of keeping the content of a loaded drug uniform until a final biodegradable microsphere is prepared, by using a single-phase mixed solution in which no phase separation by a solvent occurs in the preparation process. Thus, the preparation method of the present invention is remarkably useful for the preparation of biodegradable microspheres.
