How It Works

Salbutamol stimulates beta-2 adrenergic receptors, relaxing bronchial smooth muscle; Etofylline inhibits phosphodiesterase, increasing cAMP, and blocks adenosine receptors, leading to bronchodilation.

Mechanism Steps

1Salbutamol binds to beta-2 adrenergic receptors on bronchial smooth muscle.
2Activation of Gs protein increases adenylate cyclase activity.
3Increased cAMP leads to protein kinase A activation.
