The purpose of the drug Loperamide is to inhibit intestinal motility. The drug reduces gastrointestinal motility and slows down the movement of intestinal contents. Loperamide is used during diarrhea to relieve symptoms. Diarrhea is frequent bowel movements (more than 2 times a day) with liquid stool. Diarrhea syndrome is common even without the presence of infection. Diarrhea can be provoked by non-specific inflammatory reactions in the stomach, intestines, liver, pancreas. It appears with endocrine diseases, diseases of the nervous system, oncology. It is a reaction to drugs:
- antibiotics;
- beta blockers;
- NSAIDs (non-steroidal anti-inflammatory drugs).

Pharmacodynamics
A medicine for normalizing bowel movements. It has the ability to reduce the speed of wave-like movements of the intestine and slows down the movement of chyme (food bolus) through the gastrointestinal tract, exerting an antisecretory effect. The medicine prolongs the time of absorption of fluid and electrolytes, due to the fact that the active ingredient binds opiate receptors of the intestinal walls and inhibits the synthesis of prostaglandins and acetylcholine. The medicine activates the anal-rectal area, reducing the number of urges to empty the intestines, and thereby promotes fecal retention. It binds calmodulin (a special type of protein), which is responsible for the transport of ions in the intestinal tract. Loperamide does not have an effect similar to morphine, which distinguishes this medicine from other opioid drugs.
Pharmacokinetics
When taken orally, it is rapidly absorbed. 60 minutes (1 hour) after administration, more than 80% of the active substance is absorbed by the gastrointestinal tract, 5% by the liver. More than 96% of the drug is combined with plasma proteins. The highest content in the bloodstream accumulates after 4 hours. The half-life is 17-40 hours. Loperamide is excreted from the body with feces and bile. With stable liver function, the content of loperamide in the bloodstream and urine is low. In liver diseases, an increase in the level of loperamide in the blood plasma is noted.
Dosing and administration
Among different age groups, manufacturers recommend using an individual dosage and duration of use, which are prescribed by a therapist or pediatrician. Adults and adolescents in the acute period should take, according to the manufacturer's instructions, 4 mg of the drug (2 capsules or 2 tablets) once. The maximum permitted amount of the drug per day is 16 mg, which corresponds to 8 tablets or 8 capsules.
For therapeutic measures in chronic diarrheal syndrome, adult patients are recommended to use 2 capsules or 2 tablets daily. The drug is taken until the number of bowel movements is reduced to one or two times a day.
For elderly patients, the dose is prescribed taking into account the history of diseases and the severity of their course. The duration of treatment, dosage and administration regimen are recommended by the attending physician.
Loperamide is stopped after the stool consistency has normalized or there have been no bowel movements for 12 hours. The standard treatment cycle lasts from 1 to 2 days. If flatulence occurs during Loperamide treatment, the drug is stopped. During treatment, there is a need to replenish the fluids and microelements lost as a result of frequent bowel movements. Dietary nutrition and medications that normalize water and electrolyte balance (for example, Regidron) are required.
Patients with liver diseases take the drug with extreme caution, under close control of the organ's function. It is also necessary to monitor the condition and pay attention to clinical syndromes of nervous system intoxication.
During therapy with the drug, it is necessary to exclude activities that require:
- concentration of attention;
- concentration;
- composure;
- reaction speed.
Loperamide for diarrhea in children
Taking Loperamide by children under 6 years of age is permitted in the form of drops or tablets. Manufacturers of the drug do not recommend prescribing Loperamide to children under 2 years of age. According to statistics, there have been cases of death among children caused by paralysis of the smooth muscles of the intestine. All incidents that occurred were associated with self-prescription of Loperamide by parents, where the dosage of the drug was inadequately prescribed, and contraindications were not taken into account.
In many cases, paralytic ileus developed during the use of Loperamide for the treatment of diarrhea of infectious genesis. The result of uncontrolled use of the drug in a child's body is a violation of the water-electrolyte balance, which leads to a deterioration in the child's condition. During this period, it is necessary to saturate the child's body with liquid and microelements, because they are lost in large quantities with frequent bowel movements. All of these measures were not carried out by the parents. Given the above, WHO decided to exclude Loperamide from the list of drugs for the treatment of diarrhea syndrome in children under two years of age.
Children aged 6-8 years can take 2 mg of the medicine (1 capsule or 1 tablet) once. If the stool is liquid after defecation, the child should be given Loperamide at a dosage of 1 mg (1⁄2 tablet or 1⁄2 capsule). The maximum permissible daily dose is 3 tablets (6 mg). For the treatment of chronic diarrheal syndrome, 2 mg of Loperamide per day is prescribed.
Children aged 9-12 years are allowed to use the drug at 2 mg three times a day.
Loperamide does not help with diarrhea, what should I do?
If the stool has not returned to normal within 2 days, then the diagnosis needs to be clarified. Most often, this situation is possible if the patient has acute intestinal infection (AII). The main symptoms of this disease are:
- weakness and lethargy;
- paleness of the skin;
- loss of appetite;
- diarrhea (in severe cases with blood and mucus);
- feeling of chills;
- cramping pain in the abdomen;
- vomit.
Any reaction of the body is physiologically necessary. In case of poisoning, vomiting and diarrhea remove toxins and infected contents from the gastrointestinal tract. Using Loperamide for diarrhea caused by infection, the patient can harm himself. The contents affected by toxins will not be evacuated and will begin to poison the body from the inside, being absorbed and spreading with the bloodstream throughout the body. If the diarrhea issue has been resolved, but there is no improvement in well-being and the temperature has begun to rise, it is necessary to stop taking Loperamide. The drug does not cure, but only relieves the symptoms of diarrhea.
