NTP Formal Name Pattern

  • No part of the NTP description will be capitalized (with the exception of the “L” as a symbol/abbreviation for “litre” and as in “mL” for millilitre, and for capitalization of single letters as appropriate in a substance name (e.g., penicillin G, abobotulinumtoxinA);

  • TALLman lettering will not be used;

  • Waters of hydration will not be described in NTP substance names (see Appendix C, Hydration and Solvation)

Formal Naming Pattern for Single Active Ingredient Substance NTPs

The following pattern will be used for products with a single active ingredient substance:

<<Basis of Strength Substance (Precise ingredient substance*)>> <<Strength value and unit of measure>> <<Dose Form>> <<Unit of presentation*>>

*included only if required

The following table gives the components required to build a single ingredient NTP formal name, as well as the corresponding NTP formal name:


Basis of Strength Substance (BoSS)

Precise Ingredient Substance

Strength

Dose form

Unit of presentation

NTP_Formal_Name

levothyroxine sodium

same as BoSS

25 mcg

oral tablet

not explicitly stated

levothyroxine sodium 25 mcg oral tablet

levothyroxine sodium

same as BoSS

500 mcg per vial

powder for solution for injection

not required – stated as part of strength (vial)

levothyroxine sodium 500 mcg per vial powder for solution for injection

atorvastatin 

(atorvastatin calcium)

20 mg

oral tablet

not explicitly stated

atorvastatin (atorvastatin calcium) 20 mg oral tablet

naproxen

(naproxen, naproxen sodium)*

200 mg

oral capsule

not explicitly stated

metoclopramide hydrochloride

same as BoSS

10 mg per 2 mL

solution for injection

vial

metoclopramide hydrochloride 10 mg per 2 mL solution for injection vial
 *If two forms of an active ingredient constitute the precise active ingredient, they will be in alpha-order separated by a comma within a single set of brackets


Formal Naming Pattern for Multiple Active Ingredient Substance NTPs

The early versions of the Canadian Clinical Drug Data Set will exclude products with greater than 5 active ingredients.  The following pattern will be used for products with multiple ingredient substances:

<<Basis of Strength Substance A (Precise ingredient substance A)*>> <<Strength value and unit of measure>> <<and>> <<Basis of Strength Substance B (Precise ingredient substance B*) >> <<Strength value and unit of measure>> <<Dose Form>> <<Unit of presentation*>>

*included only if required


The following table gives the components required to build a multi-ingredient NTP formal name, as well as the corresponding NTP formal name:


Basis of Strength Substance

Precise Ingredient Substance

Strength

Dose form

Unit of presentation

NTP_Formal_Name

atorvastatin  

(amlodipine besylate)
(atorvastatin calcium)

ampoule

sulfamethoxazole 400 mg per 5 mL and trimethoprim 80 mg per 5 mL solution for injection ampoule


The following rules will be applied to all multi-ingredient NTPs:

  • “and” will be used as the conjunction between active ingredient substances/strengths;
  • The order of active ingredient substances in a multi-ingredient NTP will be alphabetical for the formal name;  the order of active substances in the French description will follow the order for the corresponding English ingredient names, and therefore ingredients might not appear in alphabetical order in French within multi-ingredient NTPs.
  • No labels
