The chemical structure of terbutaline sulfate is: Molecular formula: (C 12 H 19 NO 3 ) 2 .H 2 SO 4 CAS number: 23031-32-5 DESCRIPTION BRICANYL TURBUHALER ® is a breath activated multiple dose powder inhaler free from propellant, lubricant, preservative, carrier substances or other additives. BRICANYL Elixir is a 0.3 mg/mL oral solution with sorbitol, glycerol, citric acid - monohydrate, sodium hydroxide, sodium benzoate, disodium edetate, ethanol, purified water and raspberry flavour as inactive ingredients. BRICANYL Injection solution for injection contains 0.5 mg/mL of terbutaline sulfate with sodium chloride, hydrochloric acid (for pH adjustment) and water for injections as the inactive ingredients. PHARMACOLOGY The tertiary butyl group attached to the terminal nitrogen of the terbutaline molecule is thought to confer selective stimulation of the pulmonary β 2 -receptors and only relatively minor stimulation of cardiac β 1 receptors. The presence of the two phenolic hydroxyl groups in the meta positions confers resistance to metabolism by the enzyme catechol-o-methyl transferase. The potent bronchospasmolytic effect is rapid in onset and reaches a maximum about 30 minutes after subcutaneous injection, 1 hour after aerosol and 2 - 3 hours after oral administration. The duration of action is between 4 and 5 hours. In addition to its bronchospasmolytic effect, terbutaline has also been shown to improve Bricanyl Product Information RITA.000-292-506 Read the complete document
