Abstract :
Polymers are crucial to rapid and modified release dosage formulation. Some drug delivery systems use polymers to provide dosage forms that release the therapeutic ingredient at a steady dose over lengthy periods of time, reducing cyclic dosing. Many dose formulations use it as an excipient to capture the medicine in the bulk amount. Tablets and capsules are immediate-release, whereas extended-release and gastro-retentive release are modified-release. Polymers are modified to generate conjugates, such as polymer-drug and polymer-protein, which are employed as biological carriers. Pharmacy medication delivery relies on polymers to manage drug release through implants and other medical devices. Due to their biocompatibility with other medicinal agents and biodegradability, biodegradable polymers are frequently used in biological applications. It resists medications from the biological environment and prolongs their release to stabilise them. In vivo and in vitro biocompatibility testing are conducted for natural and synthetic biodegradable polymers utilised in biomedical applications and dosage forms. Polymers are made of many tiny molecules. Cotton, wool, rubber, Teflon (TM), and all polymers are used in most industries. A cosmic infrared absorption spectrum matches cellulose’s, proving its existence. The surface film is a cellulose pellicle. Most elastic materials, including spring metals, are elastic due to bond distortions. Rubber is long, coiled polymer chains interconnected at several locations when relaxed. Polymeric drug delivery systems aim for controlled or sustained distribution. Polysaccharides can also target oral medications to the colon. The future holds many fascinating possibilities for polymeric materials. Many applications for polymers are being developed.
