This document discusses contemporary pharmaceutics and preformulation concepts. It starts with an introduction to preformulation, which entails investigating a drug's Actual physical and chemical Qualities by yourself and with excipients.
The doc discusses sustained release dosage varieties. It commences by introducing drug delivery systems And exactly how more recent technologies have led to various strategies for delivering drugs. It then discusses The best Qualities of the drug delivery system, like protecting therapeutic drug degrees more than an extended time frame and concentrating on the site of motion.
