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

In the colon it is broken down to short chain organic acids and increases osmotic pressure in the colon, thereby causing an increase in the stool water content and stool volume.

Oponaf helps to facilitate bowel movements by drawing water into the gastrointestinal tract. The oral administration of lactitol may reduce the absorption of concomitant medications - other oral medications should be administered at least 2 hours before or 2 hours after lactitol.

How Oponaf works

Oponaf is an osmotic laxative - it exerts its pharmacologic effect by creating a hyperosmotic environment within the small intestine. The osmotic effect generated by lactitol draws water into the small intestine, which loosens stools and ultimately facilitates bowel movements.

Dosage

Oponaf dosage

2 teaspoonfuls (20 gm) once or twice daily with plenty of water

Side Effects

Abdominal distension, flatulance and abdominal cramp.

Toxicity

The LD50 is 23 g/kg in mice and >30 g/kg in rats.

Experience with acute overdosage is limited, but is likely to involve significant gastrointestinal upset and diarrhea consistent with the pharmacologic profile of lactitol. Overdosage should be managed with symptomatic and supportive measures, where necessary.

Precaution

Lactose intolerance.

Food Interaction

  • Take with food. The manufacturer recommends administration with meals.

[Moderate] ADJUST DOSING INTERVAL: Oponaf may decrease the absorption of concomitantly administered oral medications.

MANAGEMENT: Oponaf should be administered at least 2 hours before or 2 hours after concomitant oral medications.

Volume of Distribution

Data regarding the volume of distribution of lactitol are unavailable.

Elimination Route

In healthy subjects under fed conditions, oral administration of 20 grams of lactitol resulted in a mean Tmax of 3.6 ± 1.2 hours, Cmax of 776 ± 253 ng/mL, and a mean AUC of 6,019 ± 1,771 ng*hr/mL.

Half Life

The average half-life of orally administered lactitol is 2.4 hours.

Clearance

Data regarding the clearance of lactitol are unavailable.

Elimination Route

Oponaf is not absorbed in the gastrointestinal tract to any significant extent. The vast majority of an ingested dose is likely degraded into organic acids in the colon and eliminated in the feces.

Pregnancy & Breastfeeding use

Pregnancy Category - Not Classified. FDA has not yet classified the drug into a specified pregnancy category.

Contraindication
