Extended release products are designed to release their medication in a controlled manner at a predetermined rate, duration, and location to achieve and maintain optimum therapeutic blood levels of a drug. The objective of the study is to formulate and evaluate Ilaprazole Controlled release tablets comparable to the innovator product. F1-F9 formulations were prepared using varying concentrations of super disintegrates like Crospovidone, Croscarmellose sodium and Sodium starch glycolate in different concentrations. Based on the hardness, friability, weight variation, drug content, F6 formulation was found to be optimised. The selected F6 formulation was sub coated with HPMC P 50 and followed by enteric coating with Acryl-EZE-80 (Eudragit L100-55). 3 formulations (F10-F12) were prepared by using coating. Among the three formulations, F11 formulation was found to be best. FTIR studies were carried out to find out drug and excipient compatibility studies, the studies revealed that there were no interactions. DSC studies also carried out to demonstrate any changes in physical forms of the drug molecule. Keywords: Ilaprazole, Extended release tablets, Crospovidone, Croscarmellose sodium, Sodium starch glycolate, HPMC P 50, Acryl-EZE-80.

For thousands of years, human civilizations have applied substances to the skin as cosmetic and medicinal agents. However, it was not until the twentieth century that the skin came to be used as a drug delivery route. In fact, Merriam Webster dates the word “transdermal” to 1944 highlighting that it is a relatively recent concept in medical and pharmaceutical practice. Transdermal drugs are self‐contained, discrete dosage form. Drug delivery through the skin to achieve a systemic effect without producing any fluctuations in plasma concentration of the drug. Topical administration of therapeutic agents offers many advantages over conventional oral and invasive methods of drug delivery. And also provide controlled release of the drug for extended period of the time. This review article covers brief outline advantages, skin pathways for transdermal drug delivery systems (TDDS), various components of transdermal patch, and approaches for preparation of transdermal patches, evaluation of transdermal system, general clinical considerations in the use of tdds and limitation of tdds. Key words: Transdermal, Permeation pathways, Drug delivery, Matrix, ReservoirÂ
