Abstract Microspheres play a very important role as particulate drug delivery system because of their small size and other efficient properties. These have been proved to be a suitable bridge to scale the distance over to formulate an effective dosage form, so simulate controlled drag release. These microspheres are used for drug delivery, wherein the drug can be encapsulated or in entrapped form Polymeric microspheres are ideal vehicles for many controlled delivery applications due to their ability to encapsulate a variety of drugs, biocompatibility, high bioavailability and sustained drug release characteristics Controlled release drug delivery employs drug-encapsulating devices from which therapeutic agents may be released at controlled rates for long periods of time, ranging from days to months. Such systems offer numerous advantages over traditional methods of drug delivery, including tailoring of drug release rates protection of fragile drugs and increased patient comfort and compliance.
The present research work is aimed at the formulation and evaluation of novel drug delivery system for Dalbergia sissoo extract.
