๐ฟ What is Topiramate 200 mg (Topaz)?
Topaz 200 mg by Intas delivers a high-dose formulation of Topiramate, a broad-spectrum antiepileptic and migraine prophylactic. It modulates voltage-gated sodium channels, enhances GABAergic activity, antagonizes AMPA receptors, and inhibits carbonic anhydrase.
Clinical studies indicate that 200 mg daily provides robust seizure control, reducing frequency by over 70%, and decreases migraine days significantly in refractory cases. Starting at 25 mg and titrating weekly helps mitigate cognitive and weight loss side effects.
For prescribing details and safety information, refer to the FDA label for Topamax, the Drugs.com monograph, the NHS Medicines AโZ entry, and the WHO Essential Medicines List.
