In Vivo | Lomerizine (0.1 mg/kg and 1 mg/kg, i.v.) prior to ischemia and again immediately after reperfusion dose-dependently reduces the retinal damage in rat retina. Lomerizine (30 mg/kg, oral) reduces secondary necrosis at 2 weeks and secondary caspase-3 expression at 3 weeks in adult Piebald-Virol-Glaxo (PVG) rats. Lomerizine (30 mg/kg, oral) reduces morphological disruption, oxidative stress and phosphacan expression, and limits early increases in macrophage numbers in female PVG Hooded rats. Lomerizine (30 mg/kg, oral) protects RGCs from secondary death at 4 weeks but does not fully restore behavioural function (optokinetic nystagmus) in female PVG Hooded rats. Lomerizine (0.1 mg/kg or 0.3 mg/kg) significantly increases blood flow in the rabbit retina and optic nerve head (ONH), but blood flow changed little in the choroid or iris-ciliary body. Lomerizine (0.1 and 0.3 mg/kg, i.v.) significantly increases tissue blood flow in the optic nerve head and the putative blood flow in the long posterior ciliary artery with smaller reduction of blood pressure (0.3 mg/kg, i.v.) and without change in heart rate in rabbit. Lomerizine (0.1 and 0.3 mg/kg, i.v.) inhibits the hypoperfusion in the optic nerve head of rabbit. |
