Pharmaceutical Applications of Polymers

Polymers are very versatile for a series of applications including pharmaceutical applications. Natural polymers, modified natural polymers and synthetic polymers are employed as excipients in the manufacture of cosmetics and systems for conventional and modified delivery of drugs. More recently, polymers have been developed to be able to modulate and deliver drugs to target places. Biodegradable polymers, bioadhesives, biomimetic materials and responsive hydrogels have been included in pharmaceutical formulations. The advances in the concept of new drug delivery systems will only be possible with the development of polymers specifically designed for the pharmaceutical field. Therefore, this manuscript intends to review and report information regarding the use of polymers in pharmaceutical applications that can be useful in designing new systems with improved performance.
