Composition:

Active substance: diosmectite;

1 sachet contains 3 g of diosmectite (octahedral smectite);

Excipients: glucose monohydrate, sodium saccharin, vanillin.

Pharmacological Properties.

Pharmacodynamics.

In clinical pharmacology studies, diosmectite has demonstrated the ability to:

• adsorb intestinal gas in adults;
• restore normal mucosal permeability (in a clinical study conducted in children with gastroenteritis).

Due to its lamellar structure and high plastic viscosity, diosmectite exhibits strong coating properties on the mucosa of the gastrointestinal tract.

The combined results of two double-blind, randomized studies evaluating the efficacy of the medicinal product SMECTA® Vanilla compared to placebo in 602 patients aged 1 to 36 months with acute diarrhea showed a significant reduction in the frequency of bowel movements during the first 72 hours in the group receiving SMECTA® Vanilla in combination with oral rehydration therapy.

Pharmacokinetics.

Due to its structure, diosmectite in SMECTA® Vanilla remains on the luminal side of the epithelium, is neither absorbed nor metabolized. Diosmectite is excreted in the feces through normal intestinal transit.

Clinical characteristics.

Indications.

Treatment of acute diarrhea in children from 2 years of age (in addition to oral rehydration) and in adults.

Symptomatic treatment of chronic functional diarrhea in adults.

Symptomatic treatment of pain associated with functional intestinal disorders in adults.

Contraindications.

Hypersensitivity to diosmectite or to any of the excipients listed in the section "Composition".

Interaction with other medicinal products and other forms of interaction.

Due to the adsorptive properties of the medicinal product SMECTA® Vanilla, the extent and/or rate of absorption of other substances may be affected. Therefore, it is recommended not to administer other medicinal products simultaneously (an interval of at least 2 hours should be ensured, if possible).

Special precautions for use

Diosmectite should be used with caution in patients with a history of severe chronic constipation.

The use of the medicinal product SMECTA® Vanilla is not recommended for infants and children under 2 years of age. Oral rehydration solution (ORS) is the standard treatment for acute diarrhea.

In children aged 2 years and older, acute diarrhea should be treated in combination with early use of oral rehydration solution (ORS) to prevent dehydration. Chronic use of the medicinal product SMECTA® Vanilla should be avoided.

In adults, treatment does not exclude the need for rehydration when necessary.

The volume of rehydration using oral rehydration solution or intravenous rehydration depends on the severity of diarrhea, patient's age, and individual disease course.

The patient should be informed about the necessity of:

• rehydration using a significant amount of salty or sweet fluids to compensate fluid loss due to diarrhea (the average daily fluid requirement for an adult is 2 liters);
• maintaining food intake during the episode of diarrhea:
  • excluding certain foods, particularly raw vegetables and fruits, leafy greens, spicy dishes, as well as frozen food or beverages;
  • preferring baked meat and rice.
