🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAmodiaquine is rapidly absorbed from the gastrointestinal tract after oral administration. Bioavailability is approximately 70-80%.
DistributionAmodiaquine is widely distributed in body tissues, with high concentrations in the liver, spleen, and kidneys. It also crosses the placenta and is excreted in breast milk.
Protein BindingApproximately 90% bound to plasma proteins.
MetabolismAmodiaquine is extensively metabolized in the liver, primarily by cytochrome P450 enzyme CYP2C8, to its active metabolite desethylamodiaquine.
Half-LifeThe elimination half-life of amodiaquine is approximately 5 hours, while its active metabolite desethylamodiaquine has a longer half-life of 6-10 days.
ExcretionAmodiaquine and its metabolites are excreted mainly in the urine and feces.
BioavailabilityApproximately 70-80%.
Onset of ActionRapid, within 1-2 hours after oral administration.
Peak Plasma Time1-2 hours for amodiaquine; 2-4 hours for desethylamodiaquine.
Duration of ActionThe antimalarial effect lasts for several days due to the long half-life of the active metabolite.

How It Works

Amodiaquine accumulates in the acidic food vacuole of the malaria parasite, where it interferes with the polymerization of toxic heme into inert hemozoin. This leads to the accumulation of free heme, which is toxic to the parasite and causes its death. Additionally, amodiaquine may inhibit the parasite's DNA and RNA synthesis.

Mechanism Steps

1
Accumulation in food vacuole: Amodiaquine enters the parasite's food vacuole and becomes protonated, trapping it inside.
2
Inhibition of heme detoxification: It prevents the conversion of toxic heme into hemozoin, leading to heme accumulation.
3
Parasite death: The toxic heme and other effects cause oxidative damage and death of the parasite.
