The effect of black cumin oil on in vitro percutaneous absorption of the model lipophilic drug carvedilol was examined utilizing excised rat abdominal skin. Transdermal flux, permeability coefficient and improvement element were determined for various concentrations of oil in isopropyl alcohol. Black cumin oil (5% v/v) showed the greatest enhancement in permeation. The increase in the permeability of the drug is because of increased drug diffusivity through the stratum corneum under the influence of black cumin oil. A greater material of linoleic acid (and other unsaturated fats) in the oil has been postulated to be responsible for the improvement of in vitro percutaneous absorption of the drug. (2 ).
