SELF MICRO EMULSIFYING DRUG DELIVERY SYSTEM

Novel drug delivery and controlled release dosage forms cover a wide range of prolonged action of formulations which provide continuous release of their active ingredients at a predetermined rate and for a predetermined time. The majority of these formulations are designed for oral administration; however recently such devices have also been introduced for parental administration ocular insertion and for transdermal application. The most important objective for development of these systems is to furnish an extended duration of action and thus assure greater patient compliance.
