SERC-16, also known by its generic name betahistine, is a medication primarily used to manage and treat symptoms associated with Ménière's disease, a disorder of the inner ear that can lead to dizziness (vertigo), ringing in the ears (tinnitus), hearing loss, and a feeling of fullness or congestion in the ear. Betahistine works by improving blood flow in the inner ear, which reduces the buildup of pressure. Its exact mechanism of action is not fully understood, but it is thought to mimic the action of histamine, thereby dilating blood vessels and improving microcirculation within the ear. SERC-16 refers to the 16 mg dosage form of betahistine, which is taken orally. It is widely prescribed due to its efficacy in reducing the frequency and severity of vertigo attacks associated with Ménière's disease. Patients are advised to follow their healthcare provider's instructions regarding dosage and duration of treatment with SERC-16.
