The impact of black cumin oil on in vitro percutaneous absorption of the model lipophilic drug carvedilol was investigated using excised rat stomach skin. Transdermal flux, permeability coefficient and improvement element were calculated for different concentrations of oil in isopropyl alcohol. Black cumin oil (5% v/v) displayed the greatest improvement in permeation. The increase in the permeability of the drug is due to increased drug diffusivity through the stratum corneum under the influence of black cumin oil. A greater content 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 ).
