Betahistine Hydrochloride, commonly known as Serc, is a medication primarily used to treat vestibular disorders and related symptoms. This compound serves as a histamine analog, targeting specific receptors in the inner ear and central nervous system. By doing so, it can alleviate various conditions related to balance and vertigo.

Betahistine Hydrochloride’s mechanism of action revolves around its interaction with histamine receptors, specifically H1 and H3 receptors. This interaction results in a complex cascade of events that ultimately leads to increased blood flow in the inner ear, reduced neural firing, and an overall improvement in vestibular function.

Betahistine Hydrochloride is primarily prescribed for individuals suffering from Meniere’s disease, a condition characterized by recurrent episodes of vertigo, hearing loss, tinnitus, and a feeling of fullness in the ear. Additionally, it can be beneficial for those with vestibular disorders, such as vestibular migraine and labyrinthitis.

Meniere’s Disease

Meniere’s Disease is a disorder of the inner ear, named after the French physician Prosper Ménière, who first described it in 1861. It is characterized by sudden attacks of vertigo, which is a sensation of spinning or whirling, along with other symptoms like fluctuating hearing loss, tinnitus, and a feeling of congestion in the ear.

The exact cause of Meniere’s Disease remains elusive, but several factors are believed to contribute to its development. Some of these factors include Inner Ear Fluid Imbalance, Viral Infections, Genetics, Autoimmune Factors, and Allergies.
