The following combinations of drug and their mechanism of action is correct: (1)1. Guaifenesin – stimulation of β2 receptor causing bronchodilation2. Acetylcysteine – mast cell stabilization3. Budesonide – leukotriene modulators4. Theophylline – non-selective β2 receptor stimulation causing bronchodilation 5. Xylometazoline – Vasoconstriction of the mucosal blood vessels, reducing oedema of the nasal mucosa
