Improved Diagnostic Tools

Better diagnostic instruments and greater knowledge about epilepsy enable earlier and more precise diagnoses, leading to more prescriptions for zonisamide[4].

Expanded Indications

Zonisamide is being investigated for the treatment of other neurological and mental disorders, such as bipolar disorder and Parkinson’s disease, which can significantly expand its market[4].

Healthcare Spending and Insurance

Increased healthcare spending and better insurance coverage allow more patients to afford and receive treatment with zonisamide[4].

Market Penetration in Developing Nations
