🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLevamisole is rapidly absorbed from the gastrointestinal tract after oral administration. Peak plasma concentrations are typically reached within 1 to 2 hours.
DistributionLevamisole is distributed widely throughout the body, including into tissues and body fluids. It crosses the blood-brain barrier and placenta.
Protein BindingApproximately 20% of Levamisole is bound to plasma proteins.
MetabolismLevamisole is extensively metabolized in the liver, primarily through oxidation and glucuronidation. The main metabolite is 4-hydroxylevamisole.
Half-LifeThe elimination half-life of Levamisole is approximately 4 to 6 hours.
ExcretionLevamisole and its metabolites are primarily excreted in the urine, with a small amount eliminated in the feces.
BioavailabilityThe oral bioavailability of Levamisole is approximately 70-80%.
Onset of ActionThe onset of action for anthelmintic effect is typically within a few hours after oral administration.
Peak Plasma Time1 to 2 hours after oral administration.
Duration of ActionThe anthelmintic effect lasts until the worms are expelled, usually within 24 to 48 hours after a single dose.

How It Works

Levamisole acts by stimulating the nicotinic acetylcholine receptors on the muscle cells of susceptible parasitic worms. This leads to sustained muscle contraction and paralysis of the worms. The paralyzed worms are then unable to maintain their position in the host's intestine and are expelled through normal bowel movements. Additionally, Levamisole has immunomodulatory properties that may enhance the body's immune response against certain infections.

Mechanism Steps

1
Binding to nicotinic acetylcholine receptors: Levamisole binds to nicotinic acetylcholine receptors on the surface of parasite muscle cells, mimicking the action of acetylcholine.
2
Depolarization and muscle contraction: This binding causes depolarization of the muscle membrane, leading to sustained contraction of the worm's muscles.
3
Paralysis of the worm: The sustained contraction results in spastic paralysis, rendering the worm unable to move or maintain its position in the intestine.
4
Expulsion of the worm: The paralyzed worm is then expelled from the body through normal peristaltic movements and defecation.
