Pharmacotherapeutic class: Other intestinal adsorbents. ATC code: A07BC05.
Pharmacology: Pharmacodynamics: It has been demonstrated in clinical pharmacology studies that dioctahedral smectite: Adsorbs intestinal gas in adults; Restores normal permeability of the mucous membrane, observed during a clinical study in children with gastroenteritis.
Due to its layered structure and high plastic viscosity, dioctahedral smectite covers the intestinal mucosa.
The combined results of 2 double-blind randomized controlled trials comparing the efficacy of dioctahedral smectite against a placebo, in 602 patients aged 1 to 36 months who were suffering from acute diarrhea, show a significant reduction in stool output during the first 72 hours in the patient group treated with dioctahedral smectite combined with oral rehydration.
Pharmacokinetics: Given the layered structure of dioctahedral smectite, it stays on the luminal side of intestinal epithelium. It is neither absorbed nor metabolized.
Dioctahedral smectite is eliminated in the stool by the natural process of intestinal transit.
Toxicology: Preclinical safety data: Preclinical safety data from conventional acute and repeated-dose toxicity and genotoxicity studies show no evidence of particular risk to humans.

For SmectaGo, the suspension can be liquefied by kneading the sachet between the fingers before opening it. The contents of the sachet may be swallowed undiluted or mixed into some water before drinking. Preferably administer between meals.
For Smecta Strawberry, the contents of the sachet must be mixed in suspension, just before use.
In children, the contents of the sachet may be mixed with or dissolved in water in a feeding bottle or mixed with semi-liquid food such as broth, compote, puree, baby food.
In adults, the contents of the sachet may be mixed/dissolved in half a glass of water.

An overdose may lead to severe constipation or a bezoar.

Hypersensitivity to dioctahedral smectite or to any of the excipients listed in Description.
Smecta: Due to the presence of glucose and saccharose, this medication is contraindicated for patients who are fructose intolerant.

Dioctahedral smectite should be used with caution in patients with a history of severe chronic constipation.
In adults, treatment does not dispense with rehydration, if this is considered to be necessary.
The amount of rehydration by oral rehydration solution or intravenous rehydration must be adapted according to the intensity of diarrhea, and the patient's age and characteristics.
The patient must be informed of the need to: Rehydrate by drinking plenty of salty or sweet fluids to compensate for fluid loss due to diarrhea (the average daily water requirement for an adult is 2 liters); Keep up food intake while diarrhea persists by excluding certain foods, particularly raw vegetables, fruits, green vegetables, spicy dishes, as well as frozen foods or drinks, and with emphasis on grilled meats and rice.
Smecta: In children, acute diarrhea must be treated in association with the early administration of an oral rehydration solution (ORS) to avoid dehydration.
SmectaGo: This drug contains small amounts of ethanol (alcohol), below 100 mg per daily dose.
This drug contains 22.4 mg of propylene glycol in each sachet.
Effects on ability to drive and use machines: SMECTAGO has no effect or a negligible effect on the ability to drive vehicles and operate machines.
Smecta Strawberry: This medicinal product contains glucose. Its use is not recommended in patients with glucose and galactose malabsorption syndrome.
This medicinal product contains 0.128 mg propylene glycol in each sachet.
Effects on ability to drive and use machines: No adequate studies on the effect on patients' ability to drive and use machines have been performed. However, the expected effect is zero or negligible.
SmectaGo/Smecta Strawberry: In infants and children below 2 years, the use of SMECTAGO/SMECTA STRAWBERRY should be avoided. The standard treatment for acute diarrhea is administration of an oral rehydration solution (ORS).
In children above 2 years, treatment for acute diarrhea must be carried out in combination with early administration of an oral rehydration solution (ORS) to avoid dehydration. The chronic use of SMECTAGO/SMECTA STRAWBERRY should be avoided.

Smecta: There is no reliable data of teratogenesis in animals.
Clinically, no malformation or foetotoxic effect has currently come to light. However, there is not enough evidence of pregnancies exposed to SMECTA to exclude any risk.
Consequently, given that SMECTA is not absorbed, its use could be envisaged during pregnancy only if necessary.
SmectaGo/Smecta Strawberry: Pregnancy: There are no data or limited data (less than 300 pregnancies) on the use of SMECTAGO/SMECTA STRAWBERRY in pregnant women.
Animal studies are insufficient for any conclusions on reproductive toxicity.
SMECTAGO/SMECTA STRAWBERRY is not recommended during pregnancy.
Breastfeeding/Lactation: There is limited data on the use of SMECTAGO during breastfeeding. There are no data or limited data on the use of SMECTA STRAWBERRY during lactation.
SMECTAGO/SMECTA STRAWBERRY is not recommended during breastfeeding/lactation.
Fertility: Effects on fertility in humans have not been studied.

Smecta: The following adverse effects have been reported during clinical trials carried out with children and adults. These adverse effects have usually been minor and temporary and were mainly related to the digestive system.
The frequencies of adverse events have been classified as follows: frequent (≥1/100, <1/10), infrequent (≥1/1,000, ≤1/100).
Gastrointestinal problems: Frequent: Constipation usually resulting with the reduction of the dose, but which, in rare cases, may result in the treatment being stopped.
Infrequent: Flatulence, vomiting.
During post-marketing experience, cases of hypersensitive reactions (unknown frequency), comprising urticarial, rashes, pruritus and angioedema have been reported. Cases of aggravation of the constipation have also been reported.
SmectaGo/Smecta Strawberry: The most commonly reported adverse reaction during treatment is constipation, occurring in approximately 7% of adults and 1% of children. If constipation occurs, treatment with dioctahedral smectite should be discontinued, and then re-started at a lower dose if necessary.
The following table lists adverse drug reactions reported from clinical studies and post-marketing surveillance. Their frequencies are defined according to the following convention: Very common (≥1/10), Common (≥1/100 to <1/10), Uncommon (≥1/1,000 to <1/100), Rare (≥1/10,000 to <1/1,000), Very rare (<1/10,000), Unknown (cannot be estimated from the available data). Frequency is estimated from rates of occurrence observed in the clinical studies. (See table.)
