Flunarizine
Flunarizine (pronounced: flu-nar-i-zine) is a pharmacological drug primarily used as a calcium channel blocker. It is often prescribed for the prevention of migraine and for the treatment of vertigo.
Etymology
The term "Flunarizine" is derived from its chemical structure, which includes a fluorine atom (Flu-), a nitrogen atom (-nar-), and an azine group (-izine).
Pharmacology
Flunarizine is a non-selective calcium antagonist that inhibits calcium influx into cells, which prevents the contraction of smooth muscle cells and dilates blood vessels. This action can help to prevent migraines and alleviate vertigo symptoms.
Usage
Flunarizine is primarily used for the prevention of migraines. It is also used to treat vertigo and other conditions related to poor blood flow in the brain. It is not typically used for acute treatment of a migraine attack, but rather for prevention of future attacks.
Side Effects
Like all medications, Flunarizine can cause side effects. Common side effects include drowsiness, weight gain, nausea, and depression. It is important to consult with a healthcare provider before starting any new medication.
