A Review on Polymers for In situ Drug Delivery System

In situ gels have become one of the most popular and widely used techniques. These systems offer a number of benefits, including simple manufacturing, ease of use, improved adherence, and patient comfort by reducing drug administration frequency thanks to the unique characteristics of the sol to gel transition. The 'sol-gel' process involves hydrolysis, polymerization, or condensation of the precursor to form a colloidal suspension or solution. These in situ gelling methods gel at the accomplishment site since they can be administered in solution form. This review focused mostly on the introduction, advantages, disadvantages and types of polymers used to prepare in situ gels.
