Polymers have played an integral role in the advancement of drug delivery technology by providing controlled release of therapeutic agents in constant doses over long periods, cyclic dosage, and tunable release of each hydrophilic and hydrophobic medication. From early beginnings using off-the-shelf materials, the field has grown tremendously, driven partially by the innovations of chemical engineers. modern advances in drug delivery square measure currently predicated upon the rational design of polymers tailored for specific cargo and engineered to exert distinct biological functions.
Polymers play a major role in the development of drug delivery technology by release of two types of drugs like hydrophilic and hydrophobic. in a synchronized manner and constant release of formulations over extended periods. There are numerous advantages of polymers acting as an inert carrier to that a drug are often conjugated, for example the polymer improves the pharmacokinetic and pharmacodynamic properties of biopharmaceuticals through varied ways, like plasma ½ life, decreases the immunogenicity, build ups the steadiness of biopharmaceuticals, improves the solubility of low molecular weight drugs, and has a potential of targeted drug delivery.
