[Effect of the sympatholytic pirroxan on catecholamine excretion in experimental tetanus]

Excretion of catecholamines and vanilylmandelic acid was studied in rabbits with tetanic intoxication. It was found that catecholamine excretion increases up to 173% in the initial stages of the disease and falls to 51% at the height of the disease whereas excretion of vanilylmandelic acid progressively decreases down to 40% against normal. Pirroxan (10 mg/kg a day) reduces excretion of catecholamines and vanilylmandelic acid by three times, concurrently producing a definite cholinolytic effect.
