K027 is a promising new acetylcholinesterase reactivator with low acute toxicity and broad spectrum efficacy. The main aim was to compare the pharmacokinetics of K027 and trimedoxime (single i.m. application, equimolar doses). Near identical plasma profiles were obtained for both compounds. No differences were found in the Cmax mean ± SD values and AUC0-180min. However, the percent coefficient of variation of the first-order rate constant of absorption (ka) was 3-fold higher (p<0.01) providing evidence for more erratic absorption of trimedoxime.
