Abstract

Acetaminophen is the most commonly used analgesic and antipyretic agent throughout the world. In Nigeria with large dog population it is used to control pain in veterinary clinics. This study is aimed at determining the acute toxicity of acetaminophen in Nigerian local dogs. Three dogs were used for the study using the up and down method. Blood samples were collected prior to acetaminophen administration orally and at day 14 post-administration. The blood was used for haematology and serum biochemistry. Post mortem was performed on the dead dog and tissue samples obtained for histo-pathological examination. The dog treated with acetaminophen (1000 mg/kg) died within 24 ± 3.5 hours, while those treated with 500 mg/kg survived. The oral median lethal dose (LD50) was calculated to be 629.96- mg/kg indicating moderate toxicity. The haematological (RBC, PVC and Hb) values obtained pre-treatment were higher than those obtained post-treatment. Elevated biochemical (liver enzymes, BUN and creatinine) values were obtained post-treatment compared to the values obtained pre-treatment. Histopathological lesions occurred in the liver, kidney and intestine of the dead dog. The presence of anaemia, elevated liver enzymes, increased BUN and creatinine, and lesions in organs and tissues is suggestive of generalized toxicity.
