Spaquine
Spaquine Uses, Dosage, Side Effects, Food Interaction and all others data.
A 4-aminoquinoquinoline compound with anti-inflammatory properties.
Spaquine, a 4-aminoquinoline similar to chloroquine in structure and activity, has been used as both an antimalarial and an anti-inflammatory agent for more than 40 years. Spaquine is at least as effective as chloroquine, and is effective against some chloroquine-resistant strains, although resistance to amodiaquine has been reported. The mode of action of amodiaquine has not yet been determined. 4-Aminoquinolines depress cardiac muscle, impair cardiac conductivity, and produce vasodilatation with resultant hypotension. They depress respiration and cause diplopia, dizziness and nausea.

Uses
Spaquine is an antimalarial drug.
For treatment of acute malarial attacks in non-immune subjects.
How Spaquine works
The mechanism of plasmodicidal action of amodiaquine is not completely certain. Like other quinoline derivatives, it is thought to inhibit heme polymerase activity. This results in accumulation of free heme, which is toxic to the parasites. The drug binds the free heme preventing the parasite from converting it to a form less toxic. This drug-heme complex is toxic and disrupts membrane function.
Toxicity
LD50 (mouse, intraperitoneal) 225 mg/kg, LD50 (mouse, oral) 550 mg/kg. Symptoms of overdose include headache, drowsiness, visual disturbances, vomiting, hypokalaemia, cardiovascular collapse and cardiac and respiratory arrest. Hypotension, if not treated, may progress rapidly to shock. Electrocardiograms (ECG) may reveal atrial standstill, nodal rhythm, prolonged intraventricular conduction time, broadening of the QRS complex, and progressive bradycardia leading to ventricular fibrillation and/or arrest.
Elimination Route
Rapidly absorbed following oral administration.
Half Life
