Product properties

Composition

Each ml contains 40mg of tolfenamic Acid.

Mechanism of Action:

Tolfenamic Acid is a non-steroidal anti-inflammatory drug (NSAID) belonging to the fenamate group. Tolfenamic Acid exerts anti-inflammatory, analgesic and antipyretic activities. The anti inflammatory activity of Tolfenamic Acid is mainly due to an inhibition of cyclooxygenase and thus to a reduction in the synthesis of prostaglandins and thromboxanes, which are important inflammatory mediators .Tolfenamic Acid is distributed in all the organs with a high concentration in the plasma, digestive tract, liver, lungs and kidneys. However, the concentration in the brain is low. Tolfenamic Acid and its metabolites do not cross the placental barrier to any great extent. Tolfenamic Acid undergoes extensive enterohepatic recirculation and, as a result, prolonged concentrations are found in plasma.

The elimination half life varies from 8-15 hours in cattle. In cattle, Tolfenamic Acid is eliminated mainly unchanged in faeces (~30%) and urine (~70%).
