Abstract
In pharmaceutical formulation two main ingredients are required which is API and excipient. And excipient contains many components which plays vital role in manufacturing of dosage form as well as improve pharmaceutical parameters of the dosage form. Polymers used in any dosage form as excipient. Polymers have influencing capacity towards drug release and should be compatible, stable, non-toxic and economic etc. Generally, polymers are classified into three categories i.e natural, semi-synthetic and synthetic polymers. Nowadays, many pharmaceutical companies inclined towards using natural polymers due to many problems created with drug release and side effects. Polymers plays various application in formulation as excipient like to provide uniform drug delivery, rate controlling agent, taste masking agent, protective and stabilizing agents, etc. So that this review discuss about various natural polymers, there advantages over synthetic polymers and role of polymers in designing drug delivery system.
Highlights
Polymers are at the reason for noteworthy present-day items
For example, benzene (C6H6) to be a polymer of ethyne (C2H2). This definition experienced an unpretentious change (1) Polymers have been used as a principal contraption to control the drug release rate from the subtleties
Wide usage of polymers in drug transport has been recognized because polymers offer fascinating properties that have not been cultivated by some different materials
Summary
Polymers are at the reason for noteworthy present-day items Their speedy advancement in creation is caused, near social components, by the need to supersede conventional materials. He thought of, for example, benzene (C6H6) to be a polymer of ethyne (C2H2). The unprecedented wellspring of ordinary elastic, the gigantic woods tree Hevea Brasiliensis, occurs in the southern tropical district, on a very basic level in Malaysia, Indonesia, Thailand, Ceylon, India, Cambodia, Viet Nam, Brazil, Africa, and some various countries from Asia and South America. Such trees were assigned "Cau-much" or "wailing wood" in South-America. Blend holding (both covalent and non-covalent) between a filler and a polymer improves materials similitude, in this way improves certain properties of the polymeric system well past what is developed by straightforward doping with the filler.
