Effect of phenobarbitone on hepatic drug-metabolizing enzymes and urinary D-glucaric acid excretion in man

British Journal of Clinical Pharmacology

1 The activities of some hepatic drug-metabolizing enzymes representative of the four major pathways for the biotransformation of drugs were estimated in diagnostic wedge biopsy specimens obtained from 22 patients with Hodgkin's disease. Twelve patients (nine males and three females) were not on prolonged pre-operative treatment with any known inducing drugs. In this group, hexobarbitone oxidase activity, cytochrome P450 and microsomal protein contents were in the same range as those reported by other workers. 2 Ten patients (five males and five females) were pre-operatively treated with phenobarbitone (90 mg daily) for at least seven days. This resulted in a significant increase of hexobarbitone oxidase activity, cytochrome P450 and microsomal protein contents when the phenobarbitone untreated and treated groups were compared as a whole and provides direct evidence of induction of hepatic mixed function oxidase system. In respect of p-nitroreductase, 1-leucyl-beta-naphthylamide splitting enzyme and UDP glucuronyl transferase, there was no difference between the treated and untreated groups. 3 When untreated and treated patients were compared, the induction of the hepatic mixed function oxidase system, was associated with a sig...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
