The result of black cumin oil on in vitro percutaneous absorption of the model lipophilic drug carvedilol was examined using excised rat stomach skin. Transdermal flux, permeability coefficient and improvement aspect were computed for different concentrations of oil in isopropyl alcohol. Black cumin oil (5% v/v) showed the highest 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.
