HPMC – Hydroxypropylmethylcellulose

Metformin hydrochloride is a drug used in the treatment of type 2 diabetes. It shows very poor flowability and agglomeration under storage so that a direct compression of the material into tablets has not yet been successfully realized. In a previous study the authors showed that a quasi-emulsion…

A deep eutectic solvent (DES) is a eutectic system consisting of hydrogen bond donor and acceptor has been suggested as a promising formulation strategy for poorly soluble drugs. A DES consisting of choline chloride and levulinic acid in a 1:2  molar ratio was used to formulate a liquid solution of…

An efficacious topical treatment for cutaneous leishmaniasis (CL) is highly desirable but still an ongoing challenge. Systemic risedronate (Ris) has been reported to have anti-leishmanial properties and Eudragit EPO (EuE) has shown in vitro activity against L. (L.) amazonensis. The aim of this work…
