What is Mistol?
Mistol, available as 200 mcg, 100 mcg and 50 mcg tablets, contains Misoprostol, which is used to reduce the risk of NSAID related ulcers, manage miscarriages, prevent post partum hemorrhage, and also for medical termination of pregnancy.
In what conditions Mistol can be used?
· Incomplete Abortion
· In combination with mifepristone it can be used for medical termination of pregnancy.
· For protection of the lining of the stomach from NSAID-induced ulcers
How does Mistol work?
Misoprostol is a prostaglandin analog; the stimulation of prostaglandin receptors in the stomach reduces gastric acid secretion, while stimulating these receptors in the uterus and cervix can increase the strength and frequency of contractions and decrease cervical tone.
How to take Mistol?
Route of administration: Vaginally, orally, bucally 400 mcg or 800 mcg. (Smaller dose while given vaginally.)
1. Pregnancy Termination (0-12 weeks): 800 mcg of Mistol orally/vaginally/buccally administered within 48 hours following mifeprostone (Pregno) administration.
2. Missed abortion (0-12 weeks): In the absence of vaginal bleeding, 800mcg vaginally every three hours until pregnancy expulsion (generally 1-3 doses).
3. Incomplete abortion (0-12 weeks): 600 mcg buccally/orally or 400mcg vaginally in the absence of vaginal bleeding.
4. Postpartum Hemorrhage
i. Prophylaxis: 600 mcg orally within 1 minute of delivery
ii. Treatment: 800 mcg orally once; use caution if prophylactic dose already given and adverse effects present or observed
5. Induction of Labor
Vaginal low-dose misoprostol (25 mcg, 6-hourly) is recommended for induction of labour.
Not to be used in patients with previous cesarean delivery or major uterine surgery.
6. Stress Ulcer Prophylaxis
100-200 mcg orally every 4-6hr
7. NSAID-Induced Ulcer
Prophylaxis: 200 mcg orally every 6hr with food; may be decreased to 100 mcg every 6hr if higher dose is not tolerated; last dose to be administered at bedtime.
Take Mistol exactly as directed by your healthcare provider. Do not take more or less of it or take it more often or for a longer period of time than prescribed by your doctor.
What to do if a dose is missed?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What do you need to know before you take Mistol?
Tell your healthcare provider:
· If you are allergic to any component of the formulation.
· If you are getting oxytocin
· About all of your drugs (prescription or OTC, natural products, vitamins).
Do not hesitate to provide information to your healthcare provider about the underlying health conditions that you have and also about other medicines that you are currently taking.
Warnings and Precautions:
· Do not take mistol to prevent ulcers if you are pregnant or plan to become pregnant. Mistol may cause miscarriages, premature labor, or birth defects.
· If you are a woman of childbearing age, you may take mistol to prevent ulcers only if you have had a negative pregnancy test in the past 2 weeks and if you use a reliable method of birth control while taking mistol. You must begin taking misoprostol on the second or third day of your menstrual period. If you become pregnant while taking mistol, stop taking it and call your doctor immediately.
· Do not let anyone else take your medication, especially a woman who is or may become pregnant.
· Mistol is a very powerful stimulator of uterine contractions in late pregnancy and can cause fetal death and uterine rupture if used in high doses. Follow the dosage regimens carefully and do not exceed those doses.
Can Mistol be taken during pregnancy?
Use of Mistol is contraindicated in case of wanted pregnancies.
Can lactating mothers consume Mistol?
Mistol passes into breast milk. However, it is unlikely to harm a nursing infant. Consult with your healthcare provider before breast-feeding.
Should Mistol be taken with or without food?
Take Mistol with food. Food decreases incidence of diarrhea particularly when it is used for protection of the lining of the stomach from NSAID-induced ulcers.
Possible Side effects:
Mistol may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away
· stomach pain
· upset stomach
If you experience any of the following symptoms, call your doctor immediately:
· vomiting blood
bloody or black, tarry stools
Misoprostol is a prostaglandin E1 analog used to reduce the risk of NSAID induced gastric ulcers by reducing secretion of gastric acid from parietal cells. Being a synthetic prostaglandin E1 analog, it stimulates prostaglandin E1 receptors on parietal cells in the stomach to reduce gastric acid secretion. Mucus and bicarbonate secretion are also increased along with thickening of the mucosal bilayer, so the mucosa can generate new cells.
Misoprostol is also used to manage miscarriages and used alone or in combination with mifepristone for first trimester abortions. Misoprostol binds to smooth muscle cells in the uterine lining to increase the strength and frequency of contractions as well as degrade collagen and reduce cervical tone.
Absorption: Rapid absorption
Volume of distribution: Data regarding the volume of distribution of misoprostol is scarce.
Protein binding: Approximately 85%
Route of elimination: Urine
Half-life: The half life of elimination is 20-40 minutes.
