Asthma: Causes, Pathophysiology, Symptoms, Diagnosis, Treatment, and Prevention

by

Asthma is a chronic inflammatory disease of the airways characterized by recurrent episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or early in the morning. These episodes are associated with widespread but variable airflow obstruction within the lungs that is often reversible either spontaneously or with treatment. Understanding asthma involves exploring its … Read more

Sympathomimetics or adrenergic agonists or adrenergic drugs

by

Sympathomimetics, also known as adrenergic agonists or adrenergic drugs, are a class of medications that mimic the effects of the sympathetic nervous system’s neurotransmitters, particularly norepinephrine and epinephrine. These drugs primarily act on adrenergic receptors, exerting effects similar to those of the sympathetic nervous system. Classification of Sympathomimetics Sympathomimetics can be classified based on their … Read more

Emergency Drugs: Definition, Categories, and Uses

Chronic Obstructive Pulmonary Disease (COPD): Definition, etiopathogenesis, clinical manifestations, non-pharmacological and pharmacological management

by

Definition: COPD is a progressive respiratory disease characterized by chronic airflow limitation due to inflammation of the airways and destruction of lung tissue. The term COPD encompasses two main conditions: chronic bronchitis and emphysema. It is often associated with exposure to harmful gases or particles, primarily cigarette smoke, but also environmental pollutants. Etiopathogenesis: 1. Smoking: … Read more

Asthma: Definition, etiopathogenesis, clinical manifestations, non-pharmacological and pharmacological management

by

Definition: Asthma is a chronic inflammatory disorder of the airways characterized by reversible airflow obstruction, bronchospasm, and increased airway responsiveness to various stimuli. It is a common respiratory condition that can affect individuals of all ages. Etiopathogenesis: The exact cause of asthma is not fully understood, but it is likely to involve a combination of … Read more

Bronchodilators: Definition, classification, pharmacological actions, dose, indications, and contraindications

by

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 their mechanisms of action: 1. … Read more

Bronchodilators- Definition, Classification, Uses, Indications and contraindications

by

Bronchodilators are medications used to relax and widen the airways in the lungs, making breathing easier. They primarily manage respiratory conditions characterized by airway constriction, such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis. Bronchodilators are classified into three main categories based on their mechanisms of action: beta-2 adrenergic agonists, anticholinergics, and xanthine derivatives. … Read more

Salbutamol- Definition, Uses, Storage

by

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, leading to the relaxation of … Read more

Adrenergic drugs

by

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 or flight” response. These drugs … Read more
