The AIG is comprised of three portions: \r\n\r\n * the first portion (2 digits) identifies the number of active ingredients\r\n * the second portion(5 digits) identifies the unique groups of active ingredients(s);\r\n * the last portion (3 digits) identifies the active ingredient group strength. The strength group has a tolerance of -2% to +10%.\r\n \r\n\r\nFurther information about this Code System can be found at https://www.canada.ca/en/health-canada/services/drugs-health-products/drug-products/drug-product-database/terminology.html
