Thirty-two fatty acids (99.9%) have actually been determined in the fixed oil. The significant fats were linoleic acid (50.2%), oleic acid (19.9%), margaric acid (10.3%), cis-11,14- eicosadienoic acid (7.7%) and stearic acid (2.5%). The impact of black cumin oil on in vitro percutaneous absorption of the design lipophilic drug carvedilol was examined utilizing excised rat abdominal skin. Transdermal flux, permeability coefficient and enhancement factor were computed for different concentrations of oil in isopropyl alcohol. Black cumin oil (5% v/v) exhibited the greatest enhancement in permeation. The boost 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 fatty acids) in the oil has actually been postulated to be responsible for the enhancement of in vitro percutaneous absorption of the drug.
