The debrisoquine/sparteine phenotype was determined in 51 patients with depression, who were subdivided into 3 groups in terms of their drug treatment. Log (MR) for each group was compared. Patients treated with benzodiazepines had the same distribution of log (MR) as the healthy population, but the distribution was shifted towards higher values in patients treated with neuroleptics and antidepressants. It appears that the phenotypic expression of debrisoquine oxidation may be modified by drugs whose metabolism follows the same route as debrisoquine. The debrisoquine test must be carefully interpreted in patients receiving several drugs in the same time.

UI MeSH Term Description Entries
D007546 Isoquinolines A group of compounds with the heterocyclic ring structure of benzo(c)pyridine. The ring structure is characteristic of the group of opium alkaloids such as papaverine. (From Stedman, 25th ed)
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
D003647 Debrisoquin An adrenergic neuron-blocking drug similar in effects to GUANETHIDINE. It is also noteworthy in being a substrate for a polymorphic cytochrome P-450 enzyme. Persons with certain isoforms of this enzyme are unable to properly metabolize this and many other clinically important drugs. They are commonly referred to as having a debrisoquin 4-hydroxylase polymorphism. Debrisoquine,Tendor
