Escalating helminth drug resistance
Resistance-conferring β-tubulin mutations—F167Y, Q134H, E198K/V and F200Y/L—are now widespread in regions with frequent MDA cycles. Albendazole efficacy against Trichuris trichiura has dropped to 38.6%, forcing higher doses and costlier combination regimens. Limited arrival of new mechanisms of action jeopardizes the WHO roadmap for neglected-disease elimination.
Integrated vector management dampening prophylactic volumes
Deployment of environmental and biological controls is lowering malaria incidence without proportional rises in antimalarial use. As public-health agencies prioritize integrated strategies, pharmaceutical firms shift focus toward therapeutic indications and multi-action combinations that complement rather than compete with vector-control tools.

Market Opportunities and Future Outlook
Large-scale public procurement continues to define volume opportunity in human antiparasitics, particularly where mass drug administration (MDA) and elimination roadmaps convert demand into repeat, cycle-based tenders. Reported MDA coverage exceeding 860 million people annually, alongside Ghana's 2025 community rollout of 250,000 moxidectin doses for onchocerciasis, points to a practical path for long-acting macrocyclic lactones to gain share through adherence and simplified logistics, rather than higher visit frequency. WHO activity in 2025, including publishing additional target product profiles (TPPs) for neglected tropical disease (NTD) tools and updating progress reporting on NTD interventions (about 1.495 billion people requiring interventions in 2023), also reinforces whitespace for products that match public health target profiles (pediatric-friendly dosing, field-stable presentations, and deployment-compatible regimens) and for integrated packages that connect diagnosis to therapy.
Formulation and channel shifts create parallel commercial whitespace in premium and self-administered formats, while helminth resistance raises the value of differentiated mechanisms and combination regimens. Topical and implant-style delivery aligns with the market's fastest-growing administration niche in this report (topical & implants), and online pharmacy and telemedicine-enabled access expands fulfillment options for chronic or repeat-course therapies outside acute hospital care. At the same time, resistance pressures increase the need for new anthelmintic classes, and supply resiliency becomes a competitive lever as buyers and programs scrutinize continuity for benzimidazole and praziquantel-class availability. This supports opportunities for dual-sourced APIs, quality-assured generics, and lifecycle extensions that improve bioavailability without changing active moieties.
Recent Industry Developments
- May 2026: GSK reported Phase 1 findings for its visceral leishmaniasis candidate GSK3494245, and discontinued the program because pharmacokinetics did not meet target product profile criteria.

Data Sources, Market Sizing, and Validation
Desk Research
Desk work starts with building a clean view of disease burden and treatment access, then mapping how those patterns translate into drug demand and pricing at a country and regional level. We rely on public, non-paywalled references such as the World Health Organization program dashboards and guidelines, the US CDC, the European Centre for Disease Prevention and Control, and national health ministry publications for notifiable diseases and treatment protocols.
To keep the commercial side grounded, we also review sources such as SEC filings, annual reports, investor presentations, and reputable press for product mix signals, launches, and supply commentary. We then cross-check resistance notes and regimen change signals through peer-reviewed journals. Where needed, paid subscriptions for company financials, patent lookups, and shipment-level import export checks are used to sanity check revenue pools and trade exposure. These examples are not exhaustive, and other public and paid sources were also referred to for data collection, validation, and clarification.
Primary Interviews and Surveys
Primary work is used to test the model inputs that are not always visible in public datasets, especially the split between public tenders and private channels, expected pricing movement, and how regimen duration affects volumes. We spoke with a balanced mix of stakeholders, including clinicians, pharmacists, procurement professionals, distributors, and public health program contacts across major regions, then used these inputs to confirm assumptions and adjust outliers before finalizing totals.
Distribution of primary research fieldwork respondents
| Company type | Respondent position | Region |
|---|---|---|
| Top tier: 32% | CXOs: 12% | APAC: 42% |
| Mid tier: 51% | Functional/Unit leaders: 40% | EMEA: 34% |
| Smaller Players: 17% | Managers: 48% | Americas: 24% |
Market-Sizing & Forecasting
Sizing starts with a top-down build where disease prevalence, treated patient pools, and program coverage are translated into therapy volumes, then priced using realistic ASP ranges by country income level and channel. To keep the output practical, we also run selective bottom-up checks, such as sampled revenue roll-ups for key product families, channel mix checks with distributors, and volume-to-value math for high-burden indications.
Key inputs used in the model include mass drug administration coverage and cadence, shifts in resistance that change line of therapy, public procurement intensity, route of administration mix, and expected ASP progression by market and genericization status. Where bottom-up visibility is limited, we close gaps using proxy indicators like treatment guideline adoption and tender frequency, then tighten ranges through interview feedback.
Forecasts use scenario analysis supported by primary expert views. The scenarios reflect changes in elimination program funding, climate-related vector expansion pressure, and the pace of new approvals or label expansions. After scenarios are set, annual demand is projected and then converted to value using inflation-aware ASP assumptions and currency normalization rules.
Data Validation & Update Cycle
Validation is done through multiple checks, starting with alignment to independent signals such as treatment coverage trends, procurement activity, and patient access indicators, before country totals are rolled up. If a country shows a sharp jump or drop, we re-review the drivers and trigger a re-contact with relevant interviewees so the assumption can be corrected or better explained.
A second analyst review is completed to challenge arithmetic, logic, and year-to-year movements, followed by final sign-off once variances are within an explainable range. The report is refreshed annually, with interim updates made when material events occur, such as major guideline shifts, large tender cycles, or notable supply disruptions. Before delivery, a fresh final pass is completed so clients receive the latest updated view.
Mordor Intelligence's Global Antiparasitic Drugs Market Sizing Compared With Other Published Estimates
Published market values for antiparasitic drugs can look far apart because groups often count different product baskets, mix human and animal use, or apply different rules for public program volumes versus retail sales. Differences also come from how pricing is handled over time, especially when generic entry and tender pricing change ASPs quickly.
In our checks, the largest gaps usually show up around whether mass drug administration procurement is modeled as steady multi-year coverage or only as observed tender cycles, and whether adjacent categories like veterinary parasiticides or API trading are added into the same pool. Currency conversion timing, the use of constant versus current dollars, and how frequently assumptions are refreshed can also widen the spread when demand is concentrated in a few high-burden countries.
Benchmark comparison
| Source | Market Size | Gaps in Research Methodology |
|---|---|---|
| Mordor Intelligence | USD 25.97 B (2025) | |
| Global Consultancy A | USD 29.10 B (2025) | Often uses a broader pool that can blend human and veterinary antiparasitics, and it may apply higher private channel ASPs without separating tender driven price floors in high volume public programs. |
| Industry Association B | USD 22.40 B (2025) | Commonly emphasizes reported procurement and program deliveries, which can undercount retail and hospital channel demand in middle income markets and may treat episodic tenders as the full demand baseline. |
The table shows that the spread is mostly explained by what gets included and how public program volumes are translated into annual demand, then priced across channels. By keeping veterinary products and API trading outside the totals and using coverage-based demand pools plus tender price checks, the estimate stays traceable to patient treatment and procurement reality, a consistency choice applied by Mordor Intelligence.
