aqueous solubility, there by posing problems in their formulation into delivery systems.&#13;
Because of their low aqueous solubility and high permeability, dissolution and/or release rate&#13;
from the delivery system forms the rate-limiting step in their absorption and systemic&#13;
availability. This frequently results in potentially important products not reaching the market or&#13;
not achieving their full potential. Transdermal drug delivery provides the promising delivery&#13;
system for those drugs. It provides better patient compliance by avoiding invasiveness,&#13;
prolonging plasma drug level, bypass first pass effect, reduced side effects and easy termination&#13;
of therapy. Interest in organogels has increased in a wide variety of fields including chemistry,&#13;
biotechnology and pharmaceutics. It is more reasonable to look for a carrier that interacts with&#13;
the skin such that it allows various molecules to pass into the skin. In this paper, which follows&#13;
a review on investigation of lecithin organogels as carriers for the transdermal transport of&#13;
drugs having problems mentioned above. The general properties of lecithin organogels, method&#13;
of preparation and its characterization have been discussed. The potential use of lecithin&#13;
organogels for the transdermal transport of many therapeutic agents have also been discussed in&#13;
the present review.&#13;
