Warnings and precautions
-

-
Atypical electrolyte and fluid conditions:
- Fluid and electrolyte disturbances may occur, especially in patients at higher risk (eg, kidney impairment, concomitant medication that alters electrolyte balance).
- Any electrolyte abnormalities that may have existed prior to the use of this product should be rectified. Patients should also be properly hydrated before, throughout, and after each use.
- Patients who experience significant vomiting, dehydration or orthostatic hypotension should be evaluated and treated for electrolyte abnormalities after colonoscopy.
-
GI effects
- Osmotic laxatives can cause colonic mucosal and aphthous ulcerations. This includes cases of ischemic or colitis.
- When interpreting the colonoscopy results of patients suffering from inflammatory bowel disease, be cautious.
-
Seizures:
- There have been seizures associated with electrolyte abnormalities, such as hyponatremia and hypocalcemia.
- Patients with electrolyte disorders or patients at high risk of seizures should be cautious.
-
Gagging reflex in the impaired
- Watch out for semiconscious patients who have impaired gag reflex, or are prone to regurgitation during administration.
-
Renal impairment
- Patients with kidney impairment or those taking medication that can adversely affect their renal function (eg, diuretics and NSAIDs), should be cautious.
- These patients need to be hydrated properly.
- Patients with impaired renal function should be closely monitored for severe vomiting, including electrolyte measurement.
- In severe renal impairment (CrCl 30mL/minute), use is not recommended.
-
Ulcerative colitis
- Patients with severe active ulcerative colitis should be cautious.
- To rule out obstruction or perforation, it is important to perform diagnostic tests before initiating therapy.

Mechanism of action of prepopik (Sodium picosulfate, magnesium oxide, and citric acid):
- Prodrug sodium picosulfate is hydrolyzed to an active metabolite by colonic bacteria. This stimulates colonic peristalsis.
- Magnesium citrate is formed when magnesium oxide and citric acid react. This induces catharsis through the osmotic effects the unabsorbed ions within the GI tract.
Absorption:
- Magnesium cation: ≥20%
Metabolism: Sodium picosulfate:
- Hydrolyzed by colonic bacteria to the active compound bis-(phydroxy-phenyl)-pyridyl-2-methane (BHPM)
Half-life elimination:
- Sodium picosulfate: ~7.5 hours.
Time to peak:
- Sodium picosulfate: ~7 hours;
- Magnesium: 10 hours
Excretion:
- Urine
