pharmachologic effect - desensitizing, gastroprotective, analgesic, antipyretic, anti-inflammatory.

Pharmacodynamics

Amtolmetin guacil - NPVS, non-selective inhibitor of COX. Amtolmetin guacil is a precursor of tolmetin. It has anti-inflammatory, analgesic, antipyretic, desensitizing effect, has a gastroprotective effect. Suppresses pro-inflammatory factors, reduces platelet aggregation; inhibits COX-1 and COX-2, violates the metabolism of arachidonic acid, reduces the formation of PG (including in the inflammation), suppresses the exudative and proliferative phases of inflammation. Reduces capillary permeability; stabilizes lysosomal membranes; inhibits the synthesis or inactivates inflammatory mediators (PG, histamine, bradykinins, cytokines, complement factors). It blocks the interaction of bradykinin with tissue receptors, restores impaired microcirculation and reduces pain sensitivity in the inflammatory focus. Affects the thalamic centers of pain sensitivity; reduces the concentration of biogenic amines with algogenic properties; increases the threshold of pain sensitivity of the receptor apparatus. Eliminates or reduces the intensity of pain, reduces morning stiffness and swelling, increases the range of motion in the affected joints after 4 days of treatment.

The protective effect of amtolmetin guacil on the gastric mucosa is realized by stimulating the Capsaicin receptors (also called vanilloid receptors) present in the walls of the gastrointestinal tract. Due to the fact that amtolmetin guacil contains a vanillin group, it can stimulate capsaicin receptors, which in turn causes the release of the peptide encoded by the calcitonin gene and the subsequent increase in nitric oxide production (NO). Both of these actions create a counterbalance to the negative effect caused by a decrease in the number of PGs due to inhibition of COX. Amtolmetin guacil was well tolerated by patients with long-term use (for 6 months).

Pharmacokinetics

The absorption of amtolmetin guacil after oral administration is fast and complete. Basically, the drug is concentrated in the walls of the stomach and intestines, where a very high concentration is maintained for 2 hours after ingestion. After absorption of amtolmetin, guacil is immediately hydrolyzed by plasma esterases to form three metabolites: MED5, tolmetin and guviacol, which are transformed to the active metabolite of tolmetin, which penetrates into tissues, exerting a pharmacological effect. The main metabolic pathway of tolmetin is the oxidation of the methyl group on the benzene ring to the carboxyl. T_max after ingestion - 20–60 minutes.

Communication with plasma proteins - 99%. T_1/2 in adults, about 5 hours. Within 24 hours, the drug is almost completely excreted from the body in the form of glucuronides (80% with urine, 20% with bile).

Side effects

Side effects are classified according to the frequency of occurrence of a case: often 1–10%; infrequently - 0.1–1%; rarely, 0.01–0.1%; very rarely - <0.01%, including individual messages.

Gastrointestinal: often nausea; infrequently - dyspepsia, discomfort in the stomach and intestines, bloating; rarely - abdominal pain, diarrhea, vomiting, constipation, gastritis; very rarely - peptic ulcer, abnormal liver function.

Urogenital: increased urea nitrogen in the blood, urinary tract infections.

Special senses: rarely - tinnitus, visual disturbances.

Respiratory: rarely - bronchospasm, shortness of breath, rhinitis, laryngeal edema.

From the side of the central nervous system: often - dizziness, headache, drowsiness; rarely - depression.

Interaction

Inductors of microsomal oxidation in the liver (phenytoin, ethanol, barbiturates, rifampicin, phenylbutazone, tricyclic antidepressants) increase the production of hydroxylated active metabolites.

Reduces the effectiveness of uricosuric, antihypertensive drugs and diuretics.

Enhances the hypoglycemic effect of sulfonylurea derivatives, the action of anticoagulants, antiplatelet agents, fibrinolitikov, side effects of estrogen, GCS and mineralcorticoids.

Antacids and colestyramine reduce absorption.

Increases the blood concentration of drugs lithium, Methotrexate .

In some patients with impaired renal function, co-administration of NSAIDs and ACE inhibitors may lead to a further deterioration in the functioning of the kidneys.

Myelotoxic drugs increase the hematotoxicity of the drug.

Dosage and administration

Inside To preserve the gastroprotective action of the drug amtolmetin guacil should be taken on an empty stomach.
