EFFECT OF ADMINISTRATION OF ETIZOLAM ON THE DEVELOPMENT OF THE CHICK EMBRYO

There are various drugs used in daily life. Some of them show hazardous effect on various organs and some of them shows even lethal effect. Such drugs are required to banned. One of them is Etizolam   (marketed  under  the  brand  name  Sedekopan, Pasaden or Depas)  is a drug   which is a thiebenzothiodiazepines  analog. The aim of this work is done to compare the effect of administration of the etizolam drug at (Zero-day) before incubation and at the (5-day) first week of incubation, to get an idea about the extent of the teratogenic effect of this drug on the development of chick embryo. So that morphological and biochemical studies were done on the chick embryo of 8- and 16-days old chick embryos treated with (0.5mg/ml egg) of etizolam on the (zero and 5-th days) of incubation. Etizolam caused abnormality in concentration dependent manner. Enlarged remains of primitive streak was seen at 0.1mg/ml and o.3mg/ml concentration of Etizolam embryo dies. Etizolam inhibit development of somites of the development of 5-day at of incubation also it does not allow the development of notochord. The toxic effects of the drug was seen also more at 16-days treated chick embryos and the drug induced death of chick embryo at  both 8- and 16-days treated with 0.1mg/ml and o.3mg/ml. The conclusion from this study was the etizolam drug has dangerous effects on tissues and with powerful toxicity on the cells, because the drug absorbed rapidly with peak plasma levels achieved between 30 minutes and 2 hours and has a mean elimination half life of about 3 and a half hours.
