Pharmacokinetic validation of a new protocol of chronic oral administration of aripiprazole in male C57 Bl/6 mice through drinking solution.

Schizophrenia is a chronic mental illness, with a prevalence of about 1%. The symptoms are classified in three categories: positive symptoms, negative symptoms and deficits in cognitive function. Regarding the pharmacological treatment, current antipsychotics mainly improve positive symptoms while negative and cognitive symptoms remain inadequately treated.

Association between antidepressant use and delirium in older adults: an analysis of the World Health Organization's global pharmacovigilance database.

Background: Psychoactive drugs frequently cause delirium adverse events in older adults. However, few data on the relationship between antidepressants and delirium are available. Here, we investigated the association between antidepressant prescription and pharmacovigilance reports of delirium in older adults.

Micropipette-guided Drug Administration (MDA) as a non-invasive chronic oral administration method in male rats.

Background: In preclinical studies resorting to rodents, the effects of prolonged oral intake of active substances are difficult to evaluate. Indeed, to get closer to clinical reality, oral gavage (OG) is frequently used but the repetition of administrations induces risks of lesions of the digestive tract, and stress for animals which can compromise the quality of the results.

New Method: This study describes the development of a non-invasive oral administration method in male Sprague Dawley rats, as a safe alternative of OG, more faithful to clinical reality and limiting biases in pharmacokinetics and/or pharmacodynamics interpretation.
