FREE-FLOWING SOLID FORMULATIONS WITH IMPROVED BIO-AVAILABILITY OF POORLY WATER SOLUBLE DRUGS AND PROCESS FOR MAKING THE SAME

摘要

A free-flowing solid formulations of drugs or pharmaceutical agents which have poor aqueous solubility are obtained by admixing a liquid or gel composition that includes 1 to 30 per cent by weight of the drug, 5 to 60 per cent by weight of a surfactant, 10 to 40 per cent by weight of water; 1 to 20 per cent by weight of unsaturated fatty acid ester, 0 to 50 per cent by weight water miscible pharmaceutically acceptable polyol and 1 to 10 per cent by weight of phospholipid with a pharmaceutically acceptable suitable solid carrier and thereafter drying the admixture. The free­flowing powder is suitable for being formed into tablets or capsules. The drug or pharmaceutical agent is solubilized in the formulation and has significantly improved bio-availability when compared to the drug tested in its pure form.
