In Vitro Alvameline is metabolized by human liver microsomes to Lu 31-126 mainly by CYP2D6; to Lu 29-297 and Lu 25-077 mainly by CYP1A2, CYP2A6, CYP2C19, and CYP3A4; and to Lu 32-181 by CYP1A2 and possibly by CYP2C19. One metabolite, Lu 32-181, could be reduced back to alvameline, a reaction not inhibited by the applied cytochrome P-450 inhibitors[1].
In Vivo Alvameline competitively and effectively antagonizes carbachol-induced contractions and contractions induced by electrical field stimulation in human detrusor muscle. Alvameline produces a concentration-dependent rightward shift of the concentration-response curves for carbachol in both human and pig detrusor, the pKb values being 6.2 and 5.8. Contractions induced by electrical field stimulation in human detrusor are almost completely inhibited by 100 μM alvameline. In contrast, electrical field stimulation-induced contractions in pig detrusor are less sensitive to alvameline, resulting in a final inhibition of 32% with the highest concentration used (100 μM)[2]. Alvameline has been shown to improve cognitivefunction following traumatic brain injury in rats. Alvameline treated rats causes a 13% and 5% decrease in the medial septal nucleus, a 48 and 23% decrease in the vertical limb nucleus of the diagonal band, and a 51 and 28% decrease in the nucleus basalis magnocellularis, respectively[3].
Animal Admin Rats: Treatment with alvameline is initiated 24 h following TBI and rats are injected (sc) once daily for the first 15 days after injury or sham injury. Injured rats are injected daily with either saline or 15 μmol/kg of alvameline. Sham-injured rats are injected (sc) daily with either saline or 15 μmol/kg of alvameline-T[2].
