symbicort is a steroid as is fluticasone (flovent), and fluticasone is a component of advair. advair also contains a long acting beta agonist, which can keep the airways open for longer <img src="i/expressions/face-icon-small-smile.gif" border="0">
looks like bricanyl is a long acting beta agonist, so using symbicort & bricanyl together could feasibly give you the same outcome.
