Flunarizine 10 tablets is a medication that belongs to a class of drugs called calcium channel blockers. It is primarily used for the prevention and treatment of migraine headaches. Flunarizine works by blocking calcium channels in the brain, which reduces the sensitivity of the blood vessels to various triggers that can cause migraines. This helps to prevent the dilation of blood vessels in the brain, which is believed to be a contributing factor in migraine headaches. Higrin-10 tablet is typically taken once a day, mainly before bedtime.
