CRUZ-JENTOFT, Alfonso J.. Sarcopenia: what should a pharmacist know?. Farm Hosp. [online]. 2017, vol.41, n.4, pp.543-549. ISSN 2171-8695.  https://dx.doi.org/10.7399/fh.2017.41.4.10802.

Sarcopenia (or muscle insufficiency) is a geriatric syndrome characterized by a progressive and generalized loss of skeletal muscle mass and function which has adverse consequences, particularly physical disability, falls and death. It can develop slowly, as a chronic condition that emerges over many years, or acutely, generally due to immobilization associated with an acute disease.

The physiopathology of sarcopenia is complex, and affects both the muscle and its neurological and hormonal regulation.

The prevalence of sarcopenia increases with age and in certain healthcare settings (nursing homes, hospitals, rehabilitation centres). Its diagnosis is based on the documentation of a low muscle mass associated with low muscle strength and/or low physical performance. Once confirmed, a syndromic approach is needed, based on a comprehensive geriatric assessment in order to determine its causes and prepare a treatment plan which addresses the treatment of symptoms as well as the etiology.

Prevention of sarcopenia starts in the adult age, through the promotion of adequate nutritional habits, an increase in physical activity and, ideally, resistance exercise. Sarcopenia treatment must necessarily include resistance exercises (that can be associated with other types of exercise) and an improvement in diet, increasing protein intake up to 1.2-1.5 g/kg/day and covering caloric requirements. In some cases, this will require the use of nutritional supplements, which can contain leucine, beta-hydroxy beta-methylbutyrate acid (HMB) and vitamin D, in order to optimize its effects on the muscle. There are still no medications available to treat sarcopenia.
