Mechanism and action
Ventolin: Albuterol selectively activates beta-2 adrenergic receptors on bronchial smooth muscle, leading to relaxation of the airways and rapid bronchodilation within five to fifteen minutes. Prilosec: Omeprazole is a substituted benzimidazole prodrug activated in the acidic environment of the gastric parietal cell, where it irreversibly inhibits the H+/K+-ATPase enzyme — the proton pump responsible for the final step…
When Ventolin is preferred
