Lomerizine dihydrochloride is a voltage-dependent calcium channel blocker and selective cerebral vasodilator.
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.
After partial optic nerve (ON) injury, intact retinal ganglion cells (RGCs) undergo secondary death, but the topographic distribution of this death is unknown, and it is unclear which cell death pathways are involved. Although the calcium channel blocker lomerizine reduces
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

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
To investigate the modulatory effect of CJZ3, a lomerizine derivative, on P-glycoprotein (P-gp) function in rat brain microvessel endothelial cells (RBMEC). RBMEC were isolated and cultured in Dulbecco modified Eagle medium/F12 (1:1) medium, and the amount of intracellular rhodamine 123

Short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) is a rare primary headache syndrome. The diagnostic criteria include attacks of unilateral orbital, supraorbital or temporal stabbing pain accompanied by one of the following: conjunctival injection and/or tearing, nasal
