Hot-melt extrusion for producing solid solution comprising nanoparticle formulation of decoquinate is disclosed. Aqueous phase comprising the nanoparticles of hot-melt extruding products is homogeneous and stable. Provided is the composition comprising the solid solution of decoquinate and a method of hot-melt extrusion for producing this composition comprising the solid dispersion of decoquinate. Furthermore, provided is the solid solution comprising nanosized decoquinate formulation having improved water solubility and enhanced delivery of decoquinate in digestive system for absorption, increasing bioavailability, and the efficacy against malaria at the liver stage.

Nanoparticle formulations of decoquinate in the form of solid solution

Implants comprising an antimalarial agent such as decoquinate or another therapeutic drug are disclosed. The implants can be in the form of a complex comprising a drug, a lipid or lipids and optionally a polymer carrier. The present invention provides methods for preparing implants wherein the implants comprise decoquinate or another therapeutic drug, and a lipid or lipids such as cholesterol, monoglycerides, or diglycerides, and optionally a small percentage of a biocompatible polymer based on the total implant weight. The implants are useful for releasing a therapeutic drug at a constant level and maintaining a prophylactic or therapeutic level of the drug in a subject, for preventing a malarial infection or treating other diseases or disorders.
