ClassificationDigestive system drugs> Promote diarrhea drugs

Pharmacological effectsPhenolphthalein irritating laxatives, the main role in the large intestine. After oral administration in the intestinal alkaline environment to form soluble sodium salt, stimulate the plexus wall plexus, a direct role in the intestinal smooth muscle, so that peristalsis increased.At the same time phenolphthalein and inhibit intestinal absorption of water, so that water and electrolyte accumulation in the colon,resulting in laxation effect. The role of strength and intestinal size of alkaline, and its role in mild, rarely cause intestinal spasm.

PharmacokineticsPhenolphthalein after oral 6 ~ 8h effect. About 15% of oral absorption after absorption of drugs mainly in the form of glucuronide by the kidneys or excretion of excreted, some can also be excreted to the intestine by the bile, was reabsorbed in the intestine to form enterohepatic circulation, thereby prolonging the duration of action, So the role of a single administration of sustainable 3 to 4 days. The unabsorbed part is excreted via feces. Phenolphthalein can also be secreted by milk.

Indications1 for habitual intractable constipation.2. In the colon, rectal endoscopy or X-ray examination for cleaning the intestine.

Contraindications1. Allergic to phenolphthalein.2. Baby3. Appendicitis4. Rectal bleeding is not diagnosed.5. Congestive heart failure.6. Hypertension.7. Intestinal obstruction.8. Renal insufficiency.9. fecal blockage.

Precautions1. Young children and pregnant women with caution.2. Should be taken before going to bed, to avoid abuse of phenolphthalein.

Adverse reactionsPhenolphthalein is a widely accepted laxative that is readily accepted by patients. Occasionally intestinal cramps, bleeding tendency,a rare allergic reaction. Overdose or long-term drug disorders, induced arrhythmia, confusion, muscle spasms, and fatigue, and other symptoms.

DosageEach 50 ~ 200mg, Dayton clothing before going to bed. Bedridden each time 200mg. The amount of each 500mg, 1g daily. Increaseor decrease according to the patient's condition.

Medicine interactionsPhenolphthalein and sodium bicarbonate, magnesium oxide, and other alkaline drugs can cause discoloration of urine.

PoisoningPhenolphthalein (Fenofutin; fruit guide for the drug-containing tablets) as a laxative agent, due to the small amount of absorption after the results of enterohepatic circulation, the role of sustainable 3 ~ 4d. Commonly used before going to bed 0.05 ~ 0.2g. When poisoning mainlydamage the liver and kidneys.
