1. Almitrine bismesylate displays wide inter-subject variation in peak plasma concentrations and can induce peripheral polyneuropathy. 2. The phenotyped volunteer panel approach was used to examine whether almitrine oxidation displayed a genetic polymorphism of the debrisoquine/sparteine type. 3. There was no difference between poor and extensive metabolisers of debrisoquine with respect to the pharmacokinetics and metabolism of almitrine.

UI MeSH Term Description Entries
D008297 Male Males
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
D011110 Polymorphism, Genetic The regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. The concept includes differences in genotypes ranging in size from a single nucleotide site (POLYMORPHISM, SINGLE NUCLEOTIDE) to large nucleotide sequences visible at a chromosomal level.

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

D013034 Sparteine A quinolizidine alkaloid isolated from several FABACEAE including LUPINUS; SPARTIUM; and CYTISUS. It has been used as an oxytocic and an anti-arrhythmia agent. It has also been of interest as an indicator of CYP2D6 genotype. 7,14-Methano-2H,6H-dipyrido(1,2-a:1',2'-e)(1,5)diazocine, dodecahydro-, (7S-(7alpha,7aalpha,14alpha,14abeta))-,Lupinidin,Lupinidine,Pachycarpine,D-sparteine,Depasan Retard,Genisteine Alkaloid,L-Sparteine,Pachycarpine Sulfate (1:1), Pentahydrate, (7S-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine Hydrochloride, (7R-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine Hydrochloride, (7S-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine Hydroiodide, (7R-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine Monohydrochloride, (7R-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine Monohydroiodide, (7R-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine Sulfate,Sparteine Sulfate (1:1), (7S-(7alpha,7aalpha,14alpha,14aalpha))-Isomer,Sparteine Sulfate (1:1), (7S-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine Sulfate Anhydrous,Sparteine, (+)-Isomer,Sparteine, (-)-Isomer,Sparteine, (7R-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine, (7R-(7alpha,7abeta,14alpha,14abeta))-Isomer,Sparteine, (7S-(7alpha,7aalpha,14alpha,14aalpha))-Isomer,Sparteine, (7S-(7alpha,7aalpha,14alpha,14abeta))-Isomer,Sparteine, (7S-(7alpha,7abeta,14alpha,14abeta))-Isomer,alpha-Isosparteine,beta-Isosparteine,Anhydrous, Sparteine Sulfate,Sulfate Anhydrous, Sparteine,alpha Isosparteine,beta Isosparteine
