Furosemide (Lasix) is a powerful diuretic, one of the most powerful diuretics. In fact, the drug is not doping, but it is widely used in unofficial sports medicine, is listed in the list of drugs banned for admission by athletes.

Read the pharmacological action of furosemide will be interesting and understandable only to professionals, so we will get acquainted in general terms.

Sensations (based on the personal experience of the author) are approximately the following: every five minutes I want to go to the bathroom, as if the whole day was not possible to do it. The volumes of the effluent are commensurate with the sensations.
The effect lasts for 3-4 hours. In this case, calcium, magnesium and potassium are washed out of the body. In sport, the drug solves two problems. First: Furosemide (Lasix) removes traces of prohibited substances from the body. But, as said above, he himself is a prohibited drug, so his detection in the analyzes threatens with disqualification. Secondly: it is used to reduce weight and remove excess fluid (“drying”). On this, from the point of view of sports application, all the pluses end and a huge list of side effects begins.
