Luna 10mg Tablet contains Flunarizine, a calcium channel blocker primarily used for the prophylaxis of migraine headaches and the management of vestibular disorders such as vertigo. Flunarizine exerts its therapeutic effects by inhibiting the influx of calcium ions into vascular smooth muscle and neuronal cells, thereby stabilizing vascular tone and reducing neuronal excitability. This action helps prevent the onset of migraine attacks and alleviates symptoms associated with vestibular dysfunction. Luna 10mg is indicated for patients experiencing frequent migraine episodes or chronic vertigo unresponsive to conventional treatments. The recommended dosage is typically one tablet daily, preferably taken at bedtime to minimize potential sedation. Common adverse effects may include drowsiness, weight gain, and gastrointestinal disturbances; therefore, caution is advised in patients with a history of depression or Parkinsonian symptoms. Flunarizine is contraindicated in individuals with hypersensitivity to the drug, severe hepatic impairment, or existing extrapyramidal disorders. Regular monitoring is recommended during prolonged therapy to assess efficacy and detect any adverse reactions. Luna 10mg Tablet should be used under medical supervision, ensuring appropriate evaluation of benefits versus risks in each patient.
