Thermo Sensitive Polymers for Prolong Delivery of Contraceptive Hormones in Women

Priyanka Singh and Sibao Chen

Abstract

This review discusses the various available controlled release products for contraception in women as well as elaborates about the thermosensitive polymers, their characterization and application for controlled delivery of contraceptive hormones. The thermosensitive polymers are free flowing solutions in water at room temperature and turn into gel at body temperature and deliver the incorporated hormones at controlled rate for longer duration after a single subcutaneous injection. These polymers are biodegradable, biocompatible, and hold a great promise for prolonged delivery of contraceptive hormones.
