Adverse Drug Reactions in Patients with Bronchial Asthma

Adverse reactions to drugs are very common in everyday medical practice. Adverse drug reaction (ADR) is defined as any noxious, unintended and undesired effect to a drug that is administrated in standard doses by the proper route for the purpose of prophylaxis, diagnosis, or treatment . Some drug reactions may occur in everyone whereas others occur only in susceptible patients. These are factors that may impact on clinical practice. Asthmatics have a greater risk of developing ADRs. The majority of asthma patients are atopic. The most common drugs that induce ADRs in asthmatics are: aspirin and non-steroidal anti-inflammatory agents. Avoidance of a drug responsible for adverse reactions is the most important to prevent ADRs .
