PIKORATE

PIKORATE Syrup
Sodium Picosulfate 5 mg

Pharmacodynamics

Sodium Picosulfate is a locally acting laxative from the triarylmethane group, which after bacterial cleavage in
the colon, has the dual action of stimulating the mucosa of both the large intestine causing peristalsis and of
the rectum causing increased motility and a feeling of rectal fullness. The rectal effect may help to restore the
“call to stool” although its clinical relevance remains to be established.

Pharmacokinetics

After oral ingestion, sodium picosulfate reaches the colon without any appreciable absorption. Therefore,
enterohepatic circulation is avoided. By bacterial cleavage the active form, the free diphenol, is formed in the
colon. Consequently, there is an onset of action between 6 — 12 hours, which is determined by the release of
the active substance from the preparation. After administration, only small amounts of the drug are
systemically available. Urinary excretion reflects low systemic burden after oral administration. There is no
relationship between the laxative effect and plasma levels of the active diphenol.

INDICATIONS

Constipation of any aetiology and bowel clearance before surgery, childbirth or radiological investigations.
