ZONEGRAN 50MG CAP

Zonisamide, a sulfonamide derivative, primarily exerts its pharmacological effects through action as a voltage-gated sodium channel blocker and a carbonic anhydrase inhibitor. By blocking sodium channels, zonisamide stabilizes neuronal membranes and inhibits excessive neuronal firing, thereby reducing seizure activity. This mechanism is particularly relevant to its anticonvulsant effects. Additionally, its ability to inhibit carbonic anhydrase may contribute to its anticonvulsant properties, although the exact role of this inhibition in seizure control is not fully understood. The combined effects on these targets contribute to the therapeutic actions of zonisamide in managing certain types of seizures.

It is important to seek medical assistance promptly, as the severity of the overdose can vary based on the amount ingested. Medical professionals will be able to provide appropriate treatment, which may include monitoring vital signs, administering activated charcoal, and providing supportive care to manage symptoms and ensure the patient's well-being.

In the case of a missed dose of Zonisamide 50MG Capsule, it is generally advised to take the medication as soon as you remember. However, if it is almost time for your next scheduled dose, it is best to skip the missed dose and continue with your regular dosing schedule. It is important not to double the dose to make up for a missed one, as this may increase the risk of side effects. If you frequently miss doses, consider setting reminders or using a pill organizer to help you stay on track with your medication regimen. Consult your healthcare provider if you have any concerns or questions regarding missed doses.

• Carbamazepine, phenytoin, and other enzyme-inducing antiepileptic drugs may decrease Zonisamide levels, potentially reducing its effectiveness.
• Drugs metabolized by the liver, such as warfarin, may have their effects altered by Zonisamide, requiring close monitoring.
• Zonisamide may decrease the efficacy of levothyroxine, requiring dosage adjustments.
• It may increase the risk of nephrolithiasis when used with carbonic anhydrase inhibitors like topiramate or acetazolamide.
• The combination of Zonisamide with other carbonic anhydrase inhibitors or sulfonamides may increase the risk of renal calculi.

Following are the food interactions for Zonisamide 50MG Capsule:

• Avoid consuming alcohol as it can increase the risk of side effects and may cause dizziness, drowsiness, and impaired coordination.
• Grapefruit and grapefruit juice should be consumed with caution as they may alter the blood levels of Zonisamide, potentially leading to increased side effects.
