Experimental Evaluation of the Pharmacological Safety of a New Propagandic Acid Derivative with a Cardiotropic Action

We present the results of experimental studies into the pharmacological safety of a pharmaceutical substance 4-[(3-oxo-3-ethoxypropanoyl)amino]benzoic acid (Etmaben) under a single intragastric administration at various experimental doses (60–3000 mg/kg) to female laboratory outbred rats. A clinical examination of the experimental animals was carried out in order to identify signs of intoxication. To that end, the level of food and water consumption was assessed and biochemical blood tests were performed. In addition, the state of the central nervous and cardiovascular systems, physical endurance, and respiratory rate were assessed. The tested pharmaceutical substance in the studied doses after a single intragastric administration to female rats had no negative effect on the behavior, blood parameters, the state of the central nervous system and the cardiovascular system of experimental animals.
