🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is rapidly absorbed after oral administration. It is a prodrug that is converted to its active metabolite, thiorphan, in the body. The peak plasma concentration of the active metabolite is reached within about 1 hour after oral administration.
DistributionThe active metabolite of this medicine is distributed mainly in the gastrointestinal tract and to a lesser extent in other tissues. It does not cross the blood-brain barrier to a significant extent.
Protein BindingThe active metabolite of this medicine is highly bound to plasma proteins, approximately 90%.
MetabolismThis medicine is rapidly metabolized in the body to its active metabolite, thiorphan, and other inactive metabolites. The metabolism occurs mainly in the liver and intestines.
Half-LifeThe elimination half-life of the active metabolite is approximately 3 hours.
ExcretionThis medicine and its metabolites are excreted mainly through the urine and faeces. About 80% of the dose is excreted in the urine and about 20% in the faeces.
BioavailabilityThe oral bioavailability of this medicine is not well established from the available information.
Onset of ActionThe onset of action is usually within 1 to 2 hours after taking the medicine.
Peak Plasma TimeThe peak plasma concentration of the active metabolite is reached approximately 1 hour after oral administration.
Duration of ActionThe duration of action is approximately 8 to 12 hours, which is why it is usually taken two to three times a day.

How It Works

This medicine works by inhibiting the enzyme enkephalinase, which is responsible for breaking down enkephalins in the gastrointestinal tract. Enkephalins are natural opioid-like substances that help reduce the secretion of water and electrolytes into the intestine. By blocking enkephalinase, this medicine increases the levels of enkephalins, which leads to reduced intestinal secretion of water and electrolytes. This results in firmer stools and less frequent bowel movements. Unlike opioid antidiarrhoeals, this medicine does not slow down intestinal motility, so it does not prolong the presence of harmful bacteria or toxins in the gut. It also does not cross the blood-brain barrier significantly, so it does not cause central nervous system effects like sedation or respiratory depression.

Mechanism Steps

1
Inhibition of enkephalinase: This medicine binds to and inhibits the enzyme enkephalinase in the gastrointestinal tract.
2
Increased enkephalin levels: As a result of enzyme inhibition, the natural enkephalins are not broken down and their levels increase in the gut.
3
Reduced intestinal secretion: The increased enkephalins bind to opioid receptors in the intestine and reduce the secretion of water and electrolytes into the gut lumen.
4
Firmer stools: With less water and electrolyte secretion, the stools become less watery and more formed, reducing the frequency of diarrhoea.
