Tributine

Tributine Uses, Dosage, Side Effects, Food Interaction and all others data.

Tributine maleate is a noncompetitive spasmolytic agent. It possesses moderate opiate receptor affinity and has marked anti-serotonin activity especially on 'mu' receptors. It induces regulation of spontaneous activity and increases synchronization between electrophysiological spikes and contractions in isolated guinea pig strips of colon and ileum. However, it does not alter normal motility, but regulates abnormal intestinal activity.

Tributine is a spasmolytic agent that acts directly on smooth muscle to modulate gastric motility. It shows a "dual function" that stimulates or inhibits spontaneous contractions depending on the concentration and prior contractile activity in the preparation. Targeting ion conductance that regulates GI motility, trimebutine inhibits the inward calcium currents and calcium-dependent potassium currents in a concentration-dependent manner . At lower concentrations (1-10uM), trimebutine depolarizes the resting membrane potential without affecting the amplitude of contractions, which is thought to be mediated by inhibition of outward potassium currents. It is also shown to activate T-type Ca2+ channel and increase gastric emptying, intestinal and colonic contractility . At higher concentrations (100-300uM), reduced amplitude of spontaneous contractions and action potentials is thought to be mediated by inhibition of L-type Ca2+ channels and inward calcium current . Tributine mediates a local anesthetic action by acting as a weak agonist at mu opioid receptors.

Uses

Treatment and relief of symptoms associated with irritable bowel syndrome (spastic colon). Postoperative paralytic ileus in order to accelerate the resumption of the intestinal transit following abdominal surgery.

Tributine is also used to associated treatment for these conditions: Irritable Bowel Syndrome (IBS), Gastrointestinal spasms, Postoperative paralytic ileus

How Tributine works

At high concentrations, trimebutine is shown to inhibit the extracellular Ca2+ influx in the smooth muscle cells through voltage dependent L-type Ca2+ channels and further Ca2+ release from intracellular Ca2+ stores . Tributine is suggested to bind to the inactivated state of the calcium channel with high affinity. Reduced calcium influx attenuates membrane depolarization and decrease colon peristalsis. It also inhibits outward K+ currents in response to membrane depolarization of the GI smooth muscle cells at resting conditions through inhibition of delayed rectifier K+ channels and Ca2+ dependent K+ channels, which results in induced muscle contractions . Tributine binds to mu opioid receptors with more selectivity compared to delta or kappa opioid receptors but with lower affinity than their natural ligands. Its metabolites (N-monodesmethyl-trimebutine or nor-trimebutine), are also shown to bind to opoid receptors on brain membranes and myenteric synaptosomes .

Dosage

Tributine dosage

For adults: 100 mg to 200 mg, 3 times per day before meals.

Side Effects

Tributine maleate is generally well tolerated. The infrequently reported adverse effects are as follows: dry mouth, foul taste, diarrhea, dyspepsia, epigastric pain, nausea, constipation, drowsiness, fatigue, dizziness, hot/cold sensations, headache etc.

Toxicity

Common gastrointestinal adverse effects include dry mouth, foul taste, diarrhea, dyspepsia, epigastric pain, nausea and constipation. Some CNS effects include drowsiness, fatigue, dizziness, hot/cold sensations and headaches. In case of overdosage, gastric lavage is recommended. Oral LD50 in mouse and rats is >5000 mg/kg and 2500 mg/kg in rabbits, respectively. Tributine is not reported to display teratogenic, mutagenic or carcinogenic potential .

Precaution

Elderly, pregnancy and lactation

Interaction

Tributine maleate increases the duration of d-tubocurarine-induced curarization. No other druginteractions have been observed during clinical trial or otherwise reported.

Food Interaction

  • Take before a meal.

Volume of Distribution

Tributine is most likely to be accumulated in the stomach and the intestinal walls in highest concentrations. The fetal transfer is reported to be low .

Elimination Route

The free base form or salt form of trimebutine are rapidly absorbed after oral administration, with the peak plasma concentration reached after 1 hour of ingestion . The time to reach peak plasma concentration following a single oral dose of 200mg trimebutine is 0.80 hours .

Half Life

The elimination half life is approximately 1 hour following a single oral dose of 2mg/kg , and 2.77 hours following a single oral dose 200 mg .

Elimination Route

Renal elimination is predominant while excretion into feces is also observed (5-12%). About 94% of an oral dose of trimebutine is eliminated by the kidneys in the form of various metabolites and less than 2.4% of total ingested drug is recovered as unchanged parent drug in the urine .

Pregnancy & Breastfeeding use

Although teratological studies have not shown any drug related adverse effects on the course and outcome of pregnancy, the use of trimebutine maleate in pregnant women is not recommended.

Elderly, pregnancy and lactationIt is not known if trimebutine maleate passes into breast milk. This medication should be used while breast feeding only if the potential benefits outweigh risks to the nursing infants.

Contraindication

Patients with known hypersensitivity to trimebutine maleate or any excipient.

Acute Overdose

No evidence of overdosage have been reported to date. However, if overdosage should occur following oral administration, gastric lavage is recommended. Treatment should be made according to the symptoms observed.

Storage Condition

Store in a cool and dry place, protected from light and moisture. Keep out of the reach of children.
