β¦ Synopsis
The lethal doses, neurotoxic doses, anticonvulsant potencies, and protective indices for two chlorinated barbiturates, 5-(4-chlorophenyl)-5-ethylbarbituric acid (monochloro) and 5-(3,4-dichlorophenyl)-5-ethylbarbituric acid (dichloro), were determined in mice and the results compared with similar values concomitantly determined for phenobarbital. Chlorination was found to delay markedly the time for peak anticonvulsant effect and to prolong duration of action. The lethal dose for

Phenobarbital was observed to produce cardiovascular malformations in embryonic chicks. Malformations included simple ventricular septal defect, ventricular septal defect associated with dextroposition of the aorta, double outlet right ventricle, and several types of aortic arch anomalies.

## Abstract In order to determine interaction of smoking with single dose pharmacokinetics of phenobarbital, a 60 mg tablet of the drug was given to 12 healthy male subjects in two groups (6 smokers and 6 nonβsmokers) in a double blind study. An HPLC method using UV detection was developed to asses
