Biochem/physiol Actions

Lomerizine dihydrochloride is a voltage-dependent calcium channel blocker and selective cerebral vasodilator. It is one of the most selective calcium channel blockers for the CNS and cerebral arteries. It has been reported to inhibit both T-type and L-type Ca2+ currents in rat hippocampal CA1 pyramidal neurons, to prevent glutamate-induced neurotoxicity in rat hippocampal primary cell cultures, and to exhibit protective effects in animal models of migraine, ischemia and hypoxia. In Japan, lomerizine has been used as the first-line prophylactic drug for migraines.

Acquired resistance to chemotherapy is a major problem during cancer treatment. One mechanism for drug resistance is overexpression of the MDR (multidrug resistance)1 gene encoding the transmembrane efflux pump, P-glycoprotein (P-gp). Calcium channel blockers such as verapamil, nifedipine and nicardipine

Calcium channel antagonists have been employed in the prophylactic treatment of migraine. Their major action is the inhibition of Ca2+ influx into smooth muscle cells that is mediated through high voltage-sensitive Ca2+ channels. These drugs had been introduced for the

The effects of goshuyuto and chotosan, traditional Japanese medicines, on collagen-induced platelet aggregation were examined using guinea-pig blood. Goshuyuto at the concentration of 1,000 mug/mL inhibited collagen-induced platelet hyper-aggregation to the same degree as aspirin at the concentration of 100
