What is the use of artesunate injection 120mg?

Pharmaceutical Product Monograph: Artesunate Injection (120 mg)

In the pharmaceutical industry, Artesunate is a semi-synthetic derivative of artemisinin, a sesquiterpene lactone. As a pharmacist and manufacturer, I view this molecule as the “Gold Standard Antimalarial”—it is technically the first-line treatment for Severe and Complicated Malaria as per WHO 2026 Guidelines, significantly outperforming older treatments like Quinine in terms of survival rates.

At your WHO-GMP facility in Mumbai, Artesunate 120 mg is a high-impact “Life-Saving” SKU. It is specifically dosed for adult patients or older children to provide rapid clearance of parasites from the bloodstream.

Therapeutic Profile: Primary Indications

Artesunate 120 mg is strictly reserved for patients who cannot take oral medications due to the severity of their infection.

IndicationClinical ContextTechnical Rationale
Severe MalariaP. falciparum InfectionUsed when there are signs of organ dysfunction (e.g., kidney failure, jaundice) or high parasite density.
Cerebral MalariaNeurological CrisisRapidly crosses the blood-brain barrier to stop the parasite-induced “sludging” of red blood cells in the brain.
Pernicious MalariaMulti-organ FailureVital for patients with severe anemia, respiratory distress, or persistent vomiting.
Initial TreatmentEmergency StabilizationAdministered as a “loading dose” before transitioning to Oral Artemisinin-based Combination Therapy (ACT).

Mechanism: Endoperoxide Bridge Activation

Artesunate works by “bombing” the parasite from within the red blood cell:

Heme Activation: When the drug enters a malaria-infected red blood cell, it reacts with the iron (heme) released by the parasite’s digestion of hemoglobin.

Free Radical Generation: This reaction breaks the drug’s endoperoxide bridge, creating highly reactive “free radicals.”

Molecular Destruction: These radicals attack and damage the parasite’s proteins and membranes, leading to rapid death across almost all stages of the parasite’s life cycle.

The Pharmacist’s “Technical Warning”

  • The “PADAM” Risk: As a pharmacist, I must highlight a technical side effect called Post-Artesunate Delayed Hemolysis (PADAM). Some patients may experience a drop in hemoglobin 1 to 3 weeks after treatment. Monitoring is required post-discharge.

  • Reconstitution Protocol: Artesunate is unstable in liquid form. It is supplied as a dry powder with two separate ampoules: a Sodium Bicarbonate solvent (to dissolve) and a Sodium Chloride diluent (to thin for injection).

  • Immediate Use: Once reconstituted, the solution must be used within 1 hour. If it appears cloudy or contains particles, it must be discarded.

  • Transition to ACT: WHO protocols dictate that once the patient can swallow, a full 3-day course of an Oral ACT (like Artemether-Lumefantrine) must be completed to prevent resistance.

The Manufacturer’s Perspective: Technical & Export

From a production and B2B standpoint at your facility in Mumbai:

  • The “Triple-Pack” USP: On your digital marketplace, highlight your Comprehensive Injection Kit. Providing the 120 mg vial, the Bicarbonate ampoule, and the Saline ampoule in a single blister is a major technical advantage for international tenders (e.g., Global Fund, USAID).

  • Stability for Export: Artesunate powder is sensitive to high temperatures. Your WHO-PQ (Pre-qualification) standards and moisture-resistant sealing ensure a 24-month shelf life in the humid Zone IVb tropical regions of Africa and SE Asia.

  • Dossier Support: We provide full WHO-standard CTD/eCTD Dossiers to support your firm’s registration in international B2B tenders for infectious disease and tropical medicine.
