Y55: Agents primarily acting on smooth and skeletal muscles and the respiratory system

Y55.6: Antiasthmatics, not elsewhere classified

The term "Antiasthmatics, not elsewhere classified" refers to medications that are primarily used to manage and treat asthma. Asthma is a chronic disease that affects the airways of the lungs, causing them to swell, narrow, and produce excess mucus. This can result in difficulty breathing, chest tightness, coughing, and wheezing. Antiasthmatics help alleviate these symptoms by reducing inflammation, opening narrowed airways, and decreasing mucus production. However, an adverse reaction to these medications may occur, causing new symptoms or worsening existing ones. Symptoms of an adverse reaction can range from mild, such as a rash or stomach pain, to severe, such as difficulty breathing or a rapid heartbeat. If you suspect you're experiencing an adverse reaction to antiasthmatic medication, it's crucial to report these symptoms to your healthcare provider immediately.
