Therapeutic drug monitoring of docetaxel administered for breast cancer in a patient receiving rifampicin and clarithromycin to treat nontuberculous mycobacteriosis: A case report.

Docetaxel is metabolized by cytochrome P450 3A4 (CYP3A4), and is transported by organic anion transporting peptides (OATPs) and ABCB1, and its blood concentration is known to affect the risk of some docetaxel-related adverse drug reactions (ADRs). Thus, the concomitant use of docetaxel with drugs that inhibit or induce these transporters or CYP3A4 requires careful attention. A 58-year-old woman was receiving clarithromycin (400 mg twice daily), rifampicin (450 mg once daily) and ethambutol (500 mg once daily) for nontuberculous mycobacteriosis.

Characteristics of the drinking habits of people who overdose over-the-counter drugs: Insights from a nationwide Japanese survey.

Aim: To analyze the drinking habits of individuals who overdosed on over-the-counter (OTC) drugs, such as cough suppressants, antitussives, antipyretic analgesics, and combination cold medications, in Japan.

Methods: This cross-sectional study analyzed data collected from 2881 participants through a national survey conducted in Japan in 2023. Through a self-administered questionnaire, the participants were categorized into OTC (overdosed OTC drugs in the past year) and control (did not overdose OTC drugs) groups.

The onset and the development of cardiometabolic aging: an insight into the underlying mechanisms.

Metabolic compromise is crucial in aggravating age-associated chronic inflammation, oxidative stress, mitochondrial damage, increased LDL and triglycerides, and elevated blood pressure. Excessive adiposity, hyperglycemia, and insulin resistance due to aging are associated with elevated levels of damaging free radicals, inducing a proinflammatory state and hampering immune cell activity, leading to a malfunctioning cardiometabolic condition. The age-associated oxidative load and redox imbalance are contributing factors for cardiometabolic morbidities via vascular remodelling and endothelial damage.

Research on the quality evaluation of crude drugs.

As crude drugs are natural products, their quality may vary. However, the degradation of the active ingredients in the compositional changes that occur during processing and preparation also affects the medicinal properties of the Kampo formula, which uses herbal medicines; therefore, a detailed investigation of the effects of compositional changes during preparation is required. Plant constituents vary in content depending on the year of cultivation and the plant part; however, detailed studies have rarely been reported for some crude drugs.
