Piperaquine

Introduction

**Piperaquine** is an antimalarial medication commonly used in combination with other drugs like Dihydroartemisinin to treat uncomplicated Plasmodium falciparum malaria. It belongs to the class of antiprotozoal agents and is known for its long-acting effects, helping to clear the infection and prevent recurrence. Piperaquine is typically part of artemisinin-based combination therapies (ACTs), which are recommended by the World Health Organization for malaria treatment. This medicine is generally prescribed in areas with high resistance to other antimalarial drugs and is often used under strict medical supervision.

Uses of Piperaquine

• Treatment of uncomplicated malaria caused by Plasmodium falciparum
• Used in combination with artemisinin derivatives
• Prevention of malaria relapse in endemic regions

How Piperaquine works

Piperaquine works by interfering with the parasite’s ability to detoxify harmful byproducts created during the digestion of hemoglobin. It accumulates in the parasite’s food vacuole and disrupts its metabolic function, leading to parasite death. When used with artemisinin, it helps prevent resistance and provides a long-lasting antimalarial effect.

Benefits of Piperaquine

• Effective in treating resistant strains of malaria
• Provides long-term protection with fewer doses
• Reduces risk of malaria recurrence
• Can be used in artemisinin-based combination therapy (ACT)

How to take Piperaquine

Piperaquine should be taken orally, as directed by a healthcare professional. It is usually administered in fixed-dose combinations over a 3-day period. The medicine is taken with or without food, but consistency is important. Do not miss any doses, and complete the full course even if symptoms improve.
