Respiratory drugs are medications designed to treat conditions affecting the lungs and airways, such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis. These drugs can help open airways, reduce inflammation, and relieve symptoms like wheezing and shortness of breath. Common types include bronchodilators, corticosteroids, and antihistamines. These medications can be administered in various forms, including inhalers, nebulizers, and oral tablets. Inhalers deliver medication directly to the lungs, providing quick relief, while oral tablets may be used for long-term management. Proper use of respiratory drugs is essential for effective treatment and improved quality of life for patients.
