The result of black cumin oil on in vitro percutaneous absorption of the model lipophilic drug carvedilol was investigated utilizing excised rat abdominal skin. Transdermal flux, permeability coefficient and improvement factor were calculated for different concentrations of oil in isopropyl alcohol. Black cumin oil (5% v/v) exhibited the highest 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 higher material of linoleic acid (and other unsaturated fats) in the oil has been postulated to be responsible for the enhancement of in vitro percutaneous absorption of the drug. (2 ).
