RESUMO
Red yeast rice (RYR) is a dietary supplement containing monacolins obtained by fermentation of Monascus purpureus strains. Because of its structural homology with lovastatin, monacolin K inhibits HMG-CoA reductase and shows hypocholesterolemic properties comparable to synthetic statins. We studied all cases of myopathy involving RYR reported in the French national pharmacovigilance database (6 cases) and in scientific literature (9 cases). Among these cases, 9 showed elevated creatine kinase, 3 rhabdomyolysis and 2 myalgia. Recent studies seem to show good efficacy of the RYR, however, our work reports the existence of related muscular disorders. In addition, dietary supplements currently available on the market may show considerable variability of formulation and/or the presence of contaminants. When clinicobiological disorders occur, physicians should consider the eventual use of an herbal treatment.
RESUMO
Antidepressant treatments, including selective serotonin reuptake inhibitors, are associated in older adults with an increased risk of adverse effects compared to younger adults. This is partly explained by multiple drug use causing drug-drug interactions. In the present report, we describe a case of serotonin syndrome in an 88-year-old woman receiving a low dose of escitalopram. The onset of this episode could have been induced by a drug-drug interaction with an acute treatment by miconazole gingival adhesive tablets. The lack of pharmacokinetic data in the elderly population should prompt us to be especially cautious about prescription of this new formulation of miconazole in association with drugs metabolized by cytochromes P450 isoenzymes.
