🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is minimally absorbed from the small intestine. It is converted to its active form by colonic bacteria, and only a small fraction is absorbed systemically.
DistributionNot established from the available information.
Protein BindingNot established from the available information.
MetabolismThis medicine is metabolized by intestinal bacteria and liver enzymes into its active metabolite, which is responsible for its laxative effect.
Half-LifeNot established from the available information.
ExcretionThis medicine and its metabolites are primarily excreted in the feces, with a small amount eliminated in the urine.
BioavailabilityNot established from the available information.
Onset of ActionOral tablets typically produce a bowel movement within 6 to 12 hours.
Peak Plasma TimeNot established from the available information.
Duration of ActionThe laxative effect usually lasts for a few hours until the bowel is emptied.

How It Works

This medicine is a stimulant laxative that acts primarily on the large intestine. It stimulates the enteric nervous system and promotes colonic motility, leading to increased peristalsis. It also enhances the accumulation of water and electrolytes in the colon, which softens the stool and facilitates defecation.

Mechanism Steps

1
Activation in the colon: After oral intake, this medicine is converted by colonic bacteria into its active metabolite, which directly stimulates the nerve endings in the colon.
2
Stimulation of peristalsis: The active metabolite triggers strong wave-like contractions (peristalsis) in the large intestine, propelling stool forward.
3
Increased fluid secretion: This medicine also promotes the secretion of water and electrolytes into the colon, softening the stool and making it easier to pass.
