์์ฉ ๊ธฐ์ : The exact antiprotozoal mechanism of action is not fully elucidated. - It is believed to **bind and alter protozoal DNA**. - **Pharmacological Pearl**: As an 8-aminoquinoline, it likely interferes with the parasite's mitochondrial function. It generates **reactive oxygen species (ROS)** โ disrupts electron transport โ causes severe cellular and oxidative damage to the protozoa.

- Quinacrine ยท May potentiate the toxicity of one another; use of primaquine within 3 months of quinacrine is not recommended.
- Bone Marrow Depressants (e.g., amphotericin B, azathioprine, chloramphenicol, antineoplastics) ยท Concurrent use may cause an increased risk for toxicity and severe myelosuppression.
- Hemolytic Drugs (e.g., acetohydroxamic acid, sulfonylureas, quinidine, sulfonamides) ยท Concurrent use may cause an increased risk for toxicity and hemolysis.

- CBC (mandatory, monitor weekly while treating)

> **CRITICAL**: In cats, dosages **greater than 1 mg/kg** can be lethal. - **Management**: Overdoses should initially be handled aggressively using standardized protocols for removal of the drug from the gut (emesis, activated charcoal) to prevent absorption. - Provide intensive supportive care for potential methemoglobinemia, hemolysis, and myelosuppression. - Because of the potential seriousness of overdoses, it is strongly recommended to contact an animal poison control center for guidance immediately.
