Therapeutic Drug Monitoring and Pharmacogenetic Testing as Guides to Psychotropic Drug Dose Adjustment: An Observational Study.

To avoid the failures in therapy with psychotropic drugs, treatments can be personalized by applying the results of therapeutic drug monitoring and pharmacogenetic testing. The objective of the present single-center observational study was to describe the changes in psychotropic drug management prompted by therapeutic drug monitoring and pharmacogenetic testing, and to compare the effective drug concentration based on metabolic status with the dose predicted using an in silico decision tool for drug-drug interactions. The study was conducted in psychiatry wards at Lille University Hospital (Lille, France) between 2016 and 2020.

[Treatment options for drug-induced sialorrhea: Prescribing guidelines].

Objectives: Drug-induced hypersalivation is a frequent drug adverse event of psychotropic drugs. This excess salivary pooling in the mouth can cause an impairment of a patient's quality of life leading to low rates of medication adherence. The optimal management of hypersalivation is thus crucial to improve patient care.

Use of levodopa-carbidopa intestinal gel to treat patients with multiple system atrophy.

Background: Levodopa-carbidopa intestinal gel (LCIG) is an effective treatment for late-stage Parkinson's disease (PD) but had not been evaluated in levodopa-responsive patients with the parkinsonian variant of multiple system atrophy (MSA-P) and motor fluctuations. We aimed to assess the safety of LCIG in MSA-P patients.

Methods: In a retrospective, single-center study, we analyzed clinical and treatment-related data for all patients with MSA-P or PD treated with LCIG between December 2004 and November 2017.

[Oral drugs containing alcohol: Should we be careful?].

Ethanol is an excipient with known effect whose presence is regulated because it can cause adverse effects, notably a misuse. In order to raise awareness of this risk, this study searched all oral drugs with ethanol as an excipient from the Theriaque® database. All drugs marketed in France with a unit dose ethanol intake of 0.
