Uzma J. Sikilkar*
Novel drug delivery system has led to many advances in pharmaceutical industries. Newer drug delivery techniques has largely influenced the medical field. There are various drug delivery systems which are broadly categorized as conventional drug delivery system and modified drug delivery system. Conventional drug delivery systems includes certain limitations due to which new system was developed named modified drug delivery system i.e. novel drug delivery system. Novel drug delivery system many such techniques such as microencapsulation, targeted drug delivery system and nanotechnology. The pharmaceutical industries has went far away in manufacturing new medicines which eventually develops a medical practice. The main advantage of these novel drug delivery is that it gives patient compliance. Patient gets many advantages through this system because it consists of certain such as targeting receptor, controlled drug delivery, nanotechnology which helps a patient to a greater extent. Conventional drug delivery system may cause many adverse reactions due to high dose or may cause reduced therapeutic effect due to reduced dose. Also, every individual can show different pharmacological actions to same drug and dose. Hence, novel drug delivery maintains the drug concentration as well as delivers a dug to a particular site of action.
Keywords: Drug delivery, conventional drug delivery, novel drug delivery, therapeutic effect, site of action.
