Pharmacological properties
Naizilat belongs to the group of non-steroidal anti-inflammatory drugs.
The active component of the drug exhibits an active anti-inflammatory, analgesic and antipyretic effect. This activity is due to the suppression of synthetic processes of prostaglandins by non-selective inhibition of cyclooxygenase (COX) enzymes. However, unlike other NSAIDs, the drug has gastroprotective, antisecretory and antioxidant activity.
These protective effects are due to two ways. Due to the structural features of amtolmetin guacylate, the concentration of antioxidant enzymes in the gastric membrane – superoxide dismutase, catalase, glutathione – increases. This decreases the concentration of superoxide anions, peroxynitrite or peroxychloride, malondialdehyde.
Amtolmetina guacil increases the level of gastric nitric oxide synthase.
It is known that nitric oxide plays an important role in the protective mechanisms in the gastroduodenal segment, which is extremely important in suppressing the synthesis of prostaglandins. By acting on the peripheral capsaicin receptors of amtolmetin, guacil is able to provide a local anesthetic effect.
