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
