Pharmacological properties.

Pharmacodynamics.

Trimebutine is a synthetic agonist of peripheral m, d, and k opioid receptors. Its mechanism of action involves direct effects on the smooth muscle of the gastrointestinal tract and regulation of motility disorders without affecting the central nervous system. Unlike other opioids, trimebutine does not exhibit selectivity for any of the three receptor types, enabling it to either enhance or suppress peristalsis. The normalization of motility begins within 30 minutes after administration.

Pharmacokinetics.

Absorption.

After oral administration, trimebutine is almost completely absorbed.

Maximum concentration is reached within 30 minutes.

Distribution.

Plasma protein binding is approximately 5%. After oral administration, it crosses the placental barrier in an amount of approximately 0.05% and is excreted into breast milk at about 0.04%.

Metabolism.

Trimebutine is metabolized in the liver.

Elimination.

It is eliminated in the form of metabolites via urine.

Clinical characteristics.

Indications.

Irritable bowel syndrome; functional gastrointestinal disorders accompanied by abdominal pain, spasms, feeling of fullness, bloating, constipation, or diarrhea.

Contraindications.

Hypersensitivity to trimebutine or to any of the excipients of the medicinal product.

Interaction with other medicinal products and other forms of interaction.

Concomitant use of zotepine may prolong the anticholinergic effect. Trimebutine prolongs the effect of d-tubocurarine.

Special precautions for use.

The medicinal product Tribudate may cause drowsiness; therefore, it should be used with caution in patients with central nervous system depression.

Tribudate may enhance the sedative effect of medicinal products that depress the central nervous system and of ethanol.

The preparation contains lactose and therefore should not be used in patients with rare hereditary disorders such as galactose intolerance, lactase deficiency, or glucose-galactose malabsorption syndrome.
