Primaquine-–-Expert-Medical-Overview
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
- Active Compound: Primaquine phosphate
- Mechanism of Action: Disrupts mitochondrial electron transport in plasmodia, leading to oxidative damage.
- 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).
- Malaria prophylaxis: 30 mg base/day for 14 days post-exposure.
- Formulations:
- Tablets: 7.5 mg, 15 mg (base equivalent).
- Storage: Room temperature (15–30°C), protect from light.
Compatibility & Interactions
- Contraindications: G6PD deficiency, pregnancy (1st trimester), severe renal/hepatic impairment.
- Drug Interactions:
- Increased toxicity: Other hemolytic agents (e.g., dapsone).
- Reduced efficacy: CYP2D6 inhibitors (e.g., fluoxetine).
Key Advantages of Primaquine
Hypnozoitocidal Activity
- The only FDA-approved drug effective against dormant liver-stage parasites, preventing relapse.

“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.
