μμ© κΈ°μ : The exact antiprotozoal mechanism against *Giardia* is not fully elucidated, but it involves multiple pathways: * **DNA Intercalation**: Binds to DNA by inserting itself between adjacent base pairs β inhibits **RNA transcription** and **translocation**. * **Metabolic Inhibition**: Interferes with electron transport and inhibits **succinate oxidation**. * **Enzyme Inhibition**: Inhibits **cholinesterase**. * In humans, it binds to nucleoproteins to suppress lupus erythematosus (LE) cell factor.

- Alcohol Β· May cause a 'disulfiram-like' reaction if used concurrently.
- Hepatotoxic Drugs Β· Quinacrine concentrates in the liver; use with caution with other hepatotoxic agents.
- Primaquine Β· Quinacrine increases the toxicity of primaquine; do not use simultaneously.

κ³Όμ©λ
**Acute Toxicity:** Overdosage can be severe and potentially fatal. * **Clinical Signs**: CNS excitation (including seizures), severe GI disturbances, vascular collapse, and cardiac arrhythmias. * **Treatment**: * Gut emptying protocols (emesis/lavage, activated charcoal). * Supportive and symptomatic therapies. * Urinary acidification (e.g., with ammonium chloride) and forced diuresis with adequate fluid therapy to enhance renal excretion.
