Market Dynamics for Anthelmintic Drugs
The global anthelmintic drug market is driven by increasing parasitic infections, particularly in developing countries where diseases such as schistosomiasis, soil-transmitted helminths, and lymphatic filariasis remain prevalent. The market size was valued at approximately USD 3.2 billion in 2022 and is projected to grow at a compound annual growth rate (CAGR) of around 4.5% from 2023 to 2030 (source: Grand View Research).
Major factors influencing market growth include:
- Rising disease burden in tropical regions.
- Enhanced distribution channels and access in low-income areas.
- Introduction of combination therapies to combat drug resistance.
- Support from WHO and global health initiatives targeting parasitic diseases.
Leading companies such as Johnson & Johnson, Merck & Co., and Sanofi dominate the market, with the majority of revenue generated through established drugs like albendazole, mebendazole, and praziquantel.
The COVID-19 pandemic impacted supply chains and delayed some drug development activities but did not significantly hinder overall market growth due to increased focus from health agencies on disease elimination efforts.
Patent Landscape of Anthelmintic Drugs
The patent landscape for anthelmintic drugs reflects a wave of expirations, with key patents for widely used drugs now expired or close to expiration, creating opportunities for generic entry.

Recent Patent Filings and Focus
- Combination Therapies: Recent patents focus on combinations like albendazole with ivermectin or praziquantel to improve efficacy and resistance management (filed from 2015 to 2022).
- Novel Delivery Systems: Patents on sustained-release formulations and targeted delivery methods have increased, aiming to improve compliance and pharmacokinetics (2018 - 2022).
- New Chemical Entities: Efforts to develop drugs with activity against resistant parasite strains are ongoing, though few recent patents have been granted in this area.
Patent Trends Analysis
Since 2010, patent filings for new anthelmintic compounds declined, aligning with patent expirations. The market now heavily relies on generic manufacturers once patents expire, leading to price reductions and increased access.
Active patent protection remains mostly for combination formulations and formulations with novel delivery methods. The focus on drug resistance and treatment adherence has increased patent filings within these niches.
