NOVEL HERBAL DRUG DELIVERYSYSTEM: A REVIEW

Abstract

A Novel Drug Delivery System [NDDS] can be defined as new approach that combines innovative development, formulations, novel methodologies for delivering pharmaceutical compounds in the body as needed to safety achieve its desired pharmacological effects. Drug delivery is the method or process of administering pharmaceutical compound to achieve a therapeutic effect in humans or animals. Most common methods of delivery include the preferred non-invasive peroral (through the mouth), topical (skin), transmucosal (nasal, buccal, sublingual, vaginal, ocular and rectal) and inhalation routes. Many medications such as peptide and protein, antibody, vaccine and gene-based drugs, in general may not be administered using these routes because they might be susceptible to enzymatic degradation or cannot be absorbed into the systemic circulation efficiently due to molecular size and charge issues to be therapeutically effective. NDDS is advanced drug delivery system which improves drug potency, control drug release to give a sustained therapeutic effect, provide greater safety; finally, it is to target a drug specifically to a desired tissue. NDDS is a system for delivery of drug other than conventional drug delivery system. NDDS is a combination of advance technique and new dosage forms which are far better than conventional dosage forms
