Dear Editor:

I was reading with much pleasure the protocols done by the Medical Service of FC Barcelona.1 Alhough I am not a team physician, the primary care physician often has to deal with amateur athletes, and being from the Philippines, it means a lot of basketball-related injuries. The article ably discusses issues useful to a primary physician, too. The guidelines on when to give the «all clear to play» is particularly enlightening and so is the section on preventive exercises. The list of consultants and authors is also impressive, listing some well-known doctors among them. However, I am surprised that the article lists losartan as a diuretic. Reviewing the effects of the angiotensin II receptor antagonists, being a diuretic is not even mentioned. Also, its inhibition of aldosterone production and secretion may be considered as a «diuretic effect», still it is not used primarily in the clinics as a diuretic.
