Effect of propranolol hydrochloride on blood cell lipids in relation to partition coefficient and biological activity.
Considering the high lipophilicity of propranolol (log P = 3.56), its interactions with the cell membrane lipids of goat blood have been investigated. It is observed that lipid loss after incubation of blood cells with propranolol hydrochloride in salt glucose medium for varying periods of time was accompanied with significant increases in PUFAs. Amongst the PUFAs studied the omega 3 and omega 6 fatty acids, the two important precursors of eicosenoids, have shown increase in varying amounts. This phenomenon is presumably responsible for the significant cardiovascular activity of this drug.
