%0 Journal Article %T Formulation Development And Invitro Evaluation Of Matrix Type Transdermal Drug Delivery System Using Cetyl Pyridinium %J Biocoreopen %D 2017 %X At present, the most common form of delivery of drugs is the oral route, its advantage of easy administration. It also has significant drawbacks a£¿£¿poor bioavailability due to hepatic metabolism (first pass) and the tendency to produce rapid blood level spikes, which can be both cost prohibitive and inconvenient.To overcome these difficulties there is a need for the development of new drug delivery system; which will improve the therapeutic efficacy and safety of drugs. Hence in present work, an attempt is been made to provide development and optimization a matrix type Transdermal drug delivery system using water insoluble polymers with model drug as Cetylpyridinium and to study the effect of various concentration of polymers on In-vitro membrane permeation studies %K Cetylpyridinium %K TDDS. %U https://biocoreopen.org/ijnme/Formulation-Development-And-Invitro-Evaluation-Of-Matrix-Type-Transdermal-Drug-Delivery-System-Using-Cetyl-Pyridinium.php
