Respiratory drugs are medicinal agents used to relieve, treat, or prevent respiratory diseases such as asthma, chronic bronchitis, chronic obstructive pulmonary disease (COPD) and pneumonia. They can be ingested orally in the form of tablets and liquids, injections and inhalations, deploying the medication directly to the lungs thereby increasing its potency and effectiveness.
