About Biomaterials in Drug Delivery

Drug delivery decribes the formulations or technologies of transfering or administering a drug or pharmaceutical product in desired amount inside the body to achieve the desired therapeutic effect.It should be safe and reliable with proper dosage.Drug release is from diffusion, degradation, swelling, and affinity-based mechanisms. The rapid growth of nanoscale materials led the existance of injectable targeted drug delivery systems in the form of inserts (vaginal,ophthalmic), implants (intramuscular),topical(skin patches), surface coated (oral tablets),injected nanocarrier ( polymer-drug conjugates) etc.
