PHARMACHOLOGIC EFFECT

Preparation with local irritating and analgesic action.
It causes muscle relaxation, increases blood flow, facilitates the removal of irritating metabolic products (primarily lactic acid), allows you to increase the duration of exercise and improves their tolerability.
The irritating effect of racemetol helps reduce pain.
The local action is accompanied by the expansion of the vessels, causing a sensation of cooling, turning into a feeling of slight burning and tingling, followed by an analgesic effect.
Methylsalicylate is an anti-inflammatory analgesic.
Nonselectively inhibits cyclooxygenase, reducing the synthesis of prostaglandins. Normalizes the increased permeability of capillaries, improves microcirculation processes, reduces edema and infiltration of inflamed tissues. Provides only local action.
PHARMACOKINETICS

With external application, the concentration of racemetol in the systemic circulation is negligible.

Methyl salicylate, when applied externally, penetrates the tissues through unchanged skin, while analgesic concentration in the systemic blood flow is not achieved.Salicylates are excreted mainly by the kidneys;
the rate of excretion depends on the plasma concentration and pH of the urine.
INDICATIONS

- to reduce pain and stiffness in the joints and muscles in damage, sprains and inflammation;

- to reduce pain in the lower back;

- with myalgia (muscle pain) before and after sports.

DOSING MODE
