Bioavailability Study of SYN006, Pulmicort pMDI and Meptin Air in Healthy Adult.

Study Overview
=================
Brief Summary
-----------------
Budesonide + Procaterol HFA MDI is a novel asthma product containing both budesonide and procaterol in a single inhaler. Budesonide is a corticosteroid that treats underlying airway inflammation in asthma. Procaterol is a direct acting sympathomimetic with predominantly Beta-adrenoceptor stimulant activity selective to Beta-2 receptors (a Beta-2 agonist). It is used as a bronchodilator in the management of reversible airways obstructive pulmonary disease. Budesonide and Procaterol therefore have complementary effects, treating two different components of asthma.

Detailed Description
-----------------
Test drug : SYN006 HFA MDI (Budesonide + Procaterol Hydrochloride) Strength: (Budesonide 180ug and Procaterol Hydrochloride 10ug/puff) Mode of administration: Orally inhaled administration, single dose (4 puffs) Reference drug 1 : Pulmicort pMDI (Budesonide) Strength: (Budesonide 200ug/puff) Mode of administration: Orally inhaled administration, single dose (4 puffs) Reference drug 2 : Meptin Air 10ug (Procaterol Hydrochloride) Strength: (Procaterol Hydrochloride 10ug/puff) Mode of administration: Orally inhaled administration, single dose (4 puffs) One dose for each drug (Test, Reference 1 and Reference 2)with an at least 6-day washout period.
