Pharmaceutical invention and research are increasingly focusing on delivery systems which enhance desirable therapeutic objectives while minimizing side effects. Recent trends indicate that multiparticulate drug delivery systems are especially suitable for achieving controlled or delayed release oral formulations with low risk of dose dumping, flexibility of blending to attain different release patterns as well as reproducible and short gastric residence time. The release of drug from multiparticulates depends on a variety of factors including the carrier used to form the multiparticulates...

In the book, chapter-1 deals with brief introduction of Tripterygium wilfordii. Chapter-2 focuses upon basic knowledge about phytochemistry, views of different researchers about basic chemical constituents. Chapter-3 describes Pharmacological functions of triptolide. Chapter-4 mainly deals with different pharmacological activity of the plant and its importance to develop therapeutically active agent for the treatment of life threading disease.

1,3,4-thiadiazole is one of the most potent heterocyclic containing carbonic anhydrase and antibacterial inhibitor from the natural and synthetic origin. It possessed potent anticonvulsant activity in wide range preclinical in vitro and in vivo models. Recently, various 1,3,4-thiadiazole derivatives have been synthesized and evaluated their anticonvulsant activity. This review is a demonstration to compile the medicinal chemistry, anticonvulsant screening and their structural activity relationship as well as pharmacophoric pattern of various synthesized 1,3,4-thiadiazole derivatives.
