Bronchodilators: Definition, classification, pharmacological actions, dose, indications, and contraindications
Bronchodilators are a class of medications that relax and dilate the airways in the respiratory system. They are primarily used to manage various respiratory conditions characterized by bronchoconstriction, such as asthma and chronic obstructive pulmonary disease (COPD). Classification of Bronchodilators Bronchodilators are broadly classified into three main categories based on …
Bronchodilators- Definition, Classification, Uses, Indications and contraindications
Bronchodilators are medications used to relax and widen the airways in the lungs, making breathing easier.

Bronchodilators are classified into three main categories based on their mechanisms of action: beta-2 adrenergic …
Salbutamol- Definition, Uses, Storage
Salbutamol, also known as albuterol in the United States, is a medication that belongs to the class of beta-2 adrenergic agonists. It is commonly used as a bronchodilator to treat various respiratory conditions, particularly asthma and chronic obstructive pulmonary disease (COPD). Salbutamol works by stimulating beta-2 receptors in the airways, …
Adrenergic drugs
Adrenergic drugs, also known as adrenergic agonists or sympathomimetic drugs, are medications that mimic or enhance the effects of norepinephrine and epinephrine, which are neurotransmitters and hormones that activate adrenergic receptors in the body. Adrenergic receptors are part of the sympathetic nervous system and play a role in the “fight …
