Cinnarizine
Cinnarizine (pronounced: sin-nuh-rih-zeen) is a medication primarily used to treat issues related to the inner ear and circulatory system. It is classified as an antihistamine and calcium channel blocker.
Etymology
The term "Cinnarizine" is derived from the chemical compound class piperazine, to which it belongs. The prefix "Cinna-" is likely a reference to its chemical structure, which includes a cinnamyl group.
Usage
Cinnarizine is primarily used to treat conditions such as vertigo, tinnitus, Meniere's disease, and motion sickness. It works by inhibiting the influx of calcium ions into cells, which helps to regulate contractions in the arterial smooth muscle.
Side Effects
Potential side effects of Cinnarizine may include drowsiness, nausea, headache, and dry mouth. In rare cases, it can cause depression or extrapyramidal symptoms.
