   • Combination therapy with corticosteroids for inflammatory fungal conditions.

Market Hindrances

1. Competitive Pressure

   • Dominance of oral antifungals (e.g., terbinafine) for severe cases.
   • OTC availability in some markets reducing prescriptions.

2. Limited Market Penetration in Certain Regions

   • High competition in North America and Europe limits growth.
   • Limited penetration in emerging markets due to regulatory and economic hurdles.

3. Pricing and Reimbursement Challenges

   • Cost considerations influence prescription patterns, especially in price-sensitive regions.

4. Regulatory and Patent Landscape
