LIQUID CRYSTAL AS ACCELERANT IN DRUG ABSORPTION FROM TOPICAL FORMULATIONS
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2011, Vol 2, Issue 4
Abstract
Topical drug delivery has been one of the major research fields in the area of drug therapy for last few decades. However inspite of its large therapeutic potential market success has been limited. It provides the several advantages over the oral drug delivery. Percutaneous absorption involves the passage of the drug molecule from the skin surface into the stratum corneum under the influence of a concentration gradient and its subsequent diffusion through the stratum corneum and underlying epidermis, through the dermis, and into the blood circulation. Liquid crystal phase has emerged as a novel material for preparation of topical drug delivery systems. It fulfills the requirements for making drug loading and drug absorption faster from the site of application of topical formulations. Liquid crystal has got many phases in itself which can be further exploited to get a better and more efficient drug delivery system. Also a variety of areas in medical and electronics streamline can find its application. There is also a wide scope in respect to the methods by which these liquid crystals can be prepared. Different methods give rise to different kinds of liquid crystals. Topical formulations have emerged as a very useful drug delivery system as it bypasses the first pass metabolism. Also the absorption of drugs depends on the percutaneous absorption of drug from the area of application. Hence it’s required to choose such a vehicle which enhances the absorption of drug from the formulation.
