Abstract
Iontophoresis, a 250 years old technology for delivering the drug is simply based on the use of electrical potential. Being so old, it is still having too popped up just because of its unlimited aspects to work with. In the present review, I tried to compile the vast aspects of a drug delivery system termed as iontophoresis. Iontophoresis is one of the most interesting and challenging endeavors facing the pharmaceutical scientist. The systemic drug delivery systems often require large dose and are associated with gastrointestinal side effects, while topical application of solutions, suspensions, and ointments show variability in absorption patterns. Iontophoresis technique is capable of expanding the range of compounds that can be delivered through ocular, transdermal, ural, transungual, buccal or by nasal route.

INTRODUCTION
Amongst the various routes of drug delivery, oral route is perhaps the most preferred to the patient and the clinician alike. However, peroral administration of drugs has disadvantages such as hepatic first pass metabolism and enzymatic degradation within the GI tract, that prohibit oral administration of certain classes of drugs especially peptides and proteins. Consequently, other absorptive mucosae are considered as potential sites for drug administration. Transmucosal routes of drug delivery (i.e., the mucosal linings of the nasal, rectal, vaginal, ocular, and oral cavity) offer distinct advantages over peroral administration for systemic drug delivery. These advantages include possible bypass of first pass effect, avoidance of presystemic elimination within the GI tract, and, depending on the particular drug, a better enzymatic flora for drug absorption.
