🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionArtesunate is rapidly absorbed after oral administration, but it undergoes extensive first-pass metabolism. Peak plasma concentrations are typically reached within 1 to 2 hours.
DistributionArtesunate and its active metabolite dihydroartemisinin are widely distributed in the body, including into infected red blood cells. Protein binding is moderate.
Protein BindingArtesunate is approximately 60-70% bound to plasma proteins.
MetabolismArtesunate is rapidly hydrolyzed to dihydroartemisinin, which is further metabolized in the liver by glucuronidation.
Half-LifeThe elimination half-life of artesunate is very short, about 20-45 minutes, while its active metabolite dihydroartemisinin has a half-life of about 40-60 minutes.
ExcretionMetabolites are primarily excreted in the urine and bile.
BioavailabilityOral bioavailability of artesunate is approximately 60-80%, but it varies due to first-pass metabolism.
Onset of ActionRapid, within 1-2 hours after administration.
Peak Plasma Time1-2 hours for artesunate and its metabolite.
Duration of ActionThe parasiticidal effect lasts for several hours, but repeated dosing is required to maintain efficacy.

How It Works

Artesunate is a derivative of artemisinin, which is activated by heme iron within the malaria parasite. The activated drug generates free radicals that damage parasite proteins and membranes, leading to rapid parasite death. It primarily targets the asexual blood stages of the parasite, reducing parasitemia quickly.

Mechanism Steps

1
Activation by heme iron: Artesunate is activated when it encounters heme iron within the malaria parasite's digestive vacuole.
2
Free radical generation: The activated drug generates reactive oxygen species and free radicals that alkylate and damage parasite proteins.
3
Parasite death: The damage leads to disruption of parasite metabolism and membrane integrity, causing rapid parasite death.
