The Role of Allopurinol in Improving Muscle Energetics in Sarcopenia
A Prospective Study to Evaluate the Effect of Allopurinol on Muscle Energetics in Primary Sarcopenia

Sarcopenia is defined as the presence of low muscle mass and either decreased muscle strength or function. It is increasingly becoming a significant cause of frailty, loss of independence and physical disability in ageing western populations. Recent experimental evidence has revealed that skeletal muscle is particularly susceptible to damaging molecules that result in oxidative stress and that oxidative stress plays a prominent role in the development and progression of sarcopenia. The investigators have previously shown that the xanthine oxidase inhibitor allopurinol is able to abolish vascular oxidative stress and improve endothelial function in cohorts such as optimally treated chronic heart failure and chronic kidney disease. Recently, the investigators have also shown that allopurinol improves exercise tolerance and time to ST-depression in optimally treated coronary artery disease, suggesting that allopurinol could also exert its effects through ATP and/or oxygen sparing mechanisms.

Therefore, we propose a randomised double blind placebo-controlled parallel group trial of allopurinol in patients with primary sarcopenia using MR-spectroscopy and Flow Mediated Dilatation to investigate the possible mechanisms that underlie this exciting possibility

Inclusion Criteria:

  • Age 65 and over
  • Muscle strength (grip strength<20kg women;<30kg men) AND physical performance (Short Physical Performance Battery test score less than or equal to 8/12)2 This will ensure both that the study population have sarcopenia according to European consensus guidelines
  • Gait speed less than 0.8m/s

Exclusion Criteria:

  • Previously enrolled into the study
  • Pre-existing diagnosis of heart failure or any malignancy (excluding basal cell carcinoma)
  • Documented intolerance to Allopurinol
  • Immobility that would render the patient incapable of doing the Short performance Battery Test (SPBT)
