Introduction
Primaquine is a potent antimalarial medication widely recognized for its efficacy in treating and preventing malaria caused by Plasmodium vivax and Plasmodium ovale. As a critical component in malaria eradication programs, Primaquine stands out due to its unique mechanism of action, targeting the dormant liver stages (hypnozoites) of the parasite. This expert-level review highlights its technical specifications, clinical advantages, and real-world performance to assist healthcare professionals in making informed decisions.
Technical Specifications
Active Ingredient & Pharmacology

- Bioavailability: ~96% (oral administration)
- Half-life: 3–7 hours
- Metabolism: Hepatic (CYP2D6 enzyme-dependent)
Dosage & Administration
- Standard Dose:
- Radical cure of P. vivax/ovale: 15–30 mg base/day for 14 days (with food).

Customer & Clinical Reviews
Healthcare Professionals
Dr. Elena M., TropMed Specialist (★★★★★):
“Primaquine remains indispensable in our malaria control toolkit. Its hypnozoitocidal action is unmatched, though G6PD testing is non-negotiable.”Clinical Trial Data (2023 Meta-Analysis):
- Relapse Prevention: 92% efficacy in G6PD-normal patients.
- Adverse Events: <5% discontinuation rate due to side effects.
Patient Feedback
- Traveler (★★★★☆):
“Used it post-trip to Southeast Asia—no relapse, mild stomach upset but worth it.”
Conclusion
Primaquine is a gold-standard antimalarial for eliminating dormant parasites and preventing relapse. Its proven efficacy, cost-effectiveness, and dual prophylactic-curative role make it a top recommendation for:
- Travel medicine (high-risk regions).
- Public health campaigns (mass drug administration).
- Hospital formularies (tertiary care for vivax malaria).
Take Action: Consult your supplier today to ensure stock availability or explore bulk procurement options for endemic zones.
“In malaria control, Primaquine isn’t just an option—it’s a necessity.” – WHO Guidelines, 2022.
Key Notes for Optimization
- SEO Keywords: antimalarial, Plasmodium vivax, hypnozoitocidal, G6PD deficiency, malaria prophylaxis.
- CTA: Emphasize consultation with a healthcare provider for G6PD testing before use.
- Compliance: Highlight adherence to regional regulatory approvals (FDA, EMA, WHO-PQ).
