How It Works

Choline Theophyllinate inhibits phosphodiesterase, increasing cAMP; Terbutaline stimulates beta-2 adrenergic receptors, relaxing bronchial smooth muscle.

Mechanism Steps

1Choline Theophyllinate inhibits phosphodiesterase, reducing cAMP breakdown.
2Increased cAMP leads to relaxation of bronchial smooth muscle.
3Terbutaline selectively stimulates beta-2 adrenergic receptors on bronchial smooth muscle.
4Activation of beta-2 receptors increases adenylate cyclase activity, raising cAMP levels.
5Elevated cAMP causes bronchodilation and inhibits release of bronchoconstrictor mediators.
