Labelling Standard

I) Description:

This Labelling Standard applies to products, intended to be taken by mouth in the form of capsules, tablets, or oral suspension, for the symptomatic relief of flatulence.

II) Pharmaceutical Quality:

  1. All ingredient (medicinal and nonmedicinal) and finished product specifications should, as a minimum, meet the standards described in the publications referred to in Schedule B to the Food and Drugs Act, or equivalent standards. Where no Schedule B monograph exists for the dosage form, specifications should be similar to those of a comparable compendial dosage form. In the absence of a Schedule B standard for any dosage form, testing must be adequate to demonstrate the product's identity, potency, purity and quality.

  2. Special Notes:

    1. Pharmacopoeial standards (Schedule B) for formulated single and multiple ingredient antiflatulent preparations are shown in Appendix I. Note that this list is intended only as a guide and is not necessarily current or all inclusive.

    2. Finished product specifications should include tests for identification and an assay with suitable limits for the medicinal ingredient(s) including its components. The specifications for all dosage forms should include a description of the dosage form including organoleptic properties as well as physico-chemical testing e.g., pH, specific gravity, viscosity, appropriate to the dosage form. Where antimicrobial preservatives are added, an assay with suitable limits should be included. Antimicrobial preservative effectiveness should be determined in order to establish that the product is capable of resisting microbial contamination.

III) Ingredients:

  1. Single Medicinal ingredients:

    Ingredient Unit
    Simethicone mg
    Activated Charcoal mg

  2. Combinations of Medicinal Ingredients:

    Simethicone may be combined with those antacid ingredient(s) which are listed in the Antacid Labelling Standard, provided the requirements of both labelling standards are met.

  3. Nonmedicinal Ingredients:

    Nonmedicinal ingredients should be restricted to those substances, necessary for the formulation of the dosage form. Their concentration must not exceed the minimum required to provide their intended effect. They must be harmless in the amounts used, their presence must not affect the therapeutic efficacy or safety of the medicinal ingredients and they must not interfere with assays and tests for the medicinal ingredients and, if present, antimicrobial preservatives.

IV) Labelling:

  1. This labelling standard describes those requirements that are specific to this class of drugs. Other requirements described in the Regulations to the Food and Drugs Act and in the Guide for the Labelling of Drugs for Human Use must also be met.
