Note: The CDC reports that approximately 50% of the global population under 50 harbor genital HSV infection, fueling demand for antivirals like acyclovir.
2.2 Expanded Clinical Utility
Acyclovir’s therapeutic scope extends to:
- Severe herpes simplex infections, including encephalitis
- Herpes keratitis, requiring ophthalmic formulations
- Off-label uses in neonatal herpes
2.3 Growth of Hospital and Outpatient Settings
Increased hospital admissions and outpatient treatments post-COVID-19 have expanded use. The growth in immunocompromised populations (HIV/AIDS, transplant recipients) enhances prescriptions.
2.4 Patent Expiry and Generic Competition
Acyclovir sodium's patent expiry in major markets (e.g., US patent expired in 2009) enabled a proliferative generic market, reducing costs and broadening access. The proportion of generic formulations now exceeds 85% of global sales, impacting revenue but boosting volume sales.
