CYP3A subfamily activity affects the equilibrium concentration of Phenazepam in patients with anxiety disorders and comorbid alcohol use disorder.

Phenazepam is prescribed to relieve anxiety and sleep disorders during alcohol withdrawal, although it is associated with undesirable side effects. To demonstrate changes in the safety and efficacy profiles of Phenazepam in patients with anxiety disorders and comorbid alcohol use disorder. A total of 94 Russian patients with alcohol use disorder received 4.

Influence of and gene polymorphisms on pharmacokinetics of apixaban in patients with atrial fibrillation and acute stroke.

Introduction: Difficulties in non-vitamin K anticoagulant (NOAC) administration in acute stroke can be associated with changes in pharmacokinetic parameters of NOAC such as biotransformation, distribution, and excretion. Therefore, obtaining data on pharmacokinetics of NOAC and factors that affect it may help develop algorithms for personalized use of this drug class in patients with acute cardioembolic stroke.

Patients And Methods: Pharmacokinetics of apixaban in patients with acute stroke was studied earlier by Kryukov et al.

The influence of CYP3A5 polymorphisms on haloperidol treatment in patients with alcohol addiction.

Background: Isoenzymes CYP2D6 and CYP3A4, the activity of which varies widely, are involved in metabolism of haloperidol and may influence its profile of efficacy and safety.

Objective: The primary aim of this study was to estimate the relationship between CYP3A5 gene polymorphism, activity of the CYP3A isoenzyme, and the risk of development of adverse drug reactions by haloperidol in patients with alcohol abuse.

Methods: Sixty-six male alcohol-addicted patients participated in the study.

Pharmacodynamic genetic polymorphisms affect adverse drug reactions of haloperidol in patients with alcohol-use disorder.

Background: Antipsychotic action of haloperidol is due to blockade of D receptors in the mesolimbic dopamine pathway, while the adverse drug reactions are associated with striatal D receptor blockade. Contradictory data concerning the effects of genetic polymorphisms of genes encoding these receptors and associated structures (catechol-O-methyltransferase [COMT], glycine transporter and gene encoding the density of D receptors on the neuronal membrane) are described.

Objective: The objectives of this study were to evaluate the correlation between DRD2, SLC6A3 (DAT) and COMT genetic polymorphisms and to investigate their effect on the development of adverse drug reactions in patients with alcohol-use disorder who received haloperidol.
