Abstract

Serum activities of gamma glutamyl transpeptidase, alanine and aspartate aminotransferases, and alkaline phosphatase were determined in children on long-term treatment with aminopyrine. Gamma glutamyl transpeptidase activity was increased up to 15 times above the upper normal limit in children, who received aminopyrine for two weeks or longer. Livers of rats treated with aminopyrine (600 mg/kg/day for 18 to 25 days) had an exceedingly increased activity of gamma glutamyl transpeptidase and a slightly elevated microsomal cytochrome P-450 content. Apparently isolated enhancement of serum gamma glutamyl transpeptidase during aminopyrine medication represents a drug-induced increase of microsomal liver enzymes without clinical relevance and without evidence of damage of liver cells.
