A REVIEW ON CONTROLLED RELEASE BEADS OF ANTI-MICROBIAL DRUG

Abstract

Alginate and chitosan polymers are widely used in the preparation of drug release. These two polymers can be used together or separately to form modified drug-loaded release beads. A method of ionotropic gelation and subtle modification in various ways is used to fix these beads of different characteristics. Bead characteristics such as morphology, buoyancy, inflammatory environment, drug efficacy, marketing, and liberal behavior are important and the therapeutic use of various bead modifications can be great for underwater soluble drugs, half-life biological Health, requires direct organ guidance, and has natural protein. The need for longer and better control over drug administration has increased the need for stitched polymers. Hydrocolloids such as alginate can play an important role in the production of a controlled by-product. At low pH the flow of, alginic acid leads to the formation of a high-viscosity ‘‘acid gel.’’ Alginate is also easily applied to the gel in the presence of a divalent cation like calcium ion. This review discusses the current use the future opportunities for alginate as a tool in drug development. Keywords: Alginate, chitosan, Controlled Release, Drug Delivery, ionotropic gelation, beads
