Antihistamine is a drug that blocks the effects of histamine released during an allergy attack to treat allergic reaction symptoms. Side effects may include vision changes, confusion, irregular heartbeat, tremors, trouble urinating, unusual bleeding or bruising, and weakness. Bronchodilators open airways to treat asthma by clearing mucus and allowing more air flow through bronchial tubes. Different bronchodilators include beta-agonists administered via inhaler or orally, and anticholinergics for some individuals who cannot tolerate short-acting beta-agonists. Antibiotics are substances derived from microorganisms that can destroy or inhibit other microorganisms and are used to treat bacterial infections. Common

4. bronchodilatorBronchodilators are drugs used to treat asthma. Bronchodilators open up the bronchial tubes so that more air can move through. Bronchodilators also help clear mucus from the lungs. As the airways open, the mucus moves more freely and can be coughed out more easily.

5. Different bronchodilators for treating asthma symptoms Beta-agonists- Beta-agonists can be administered by inhalers or orally. They are called "agonists" because they activate the beta-2 receptor on the muscles surrounding the airways. Anticholinergics- Anticholinergics provide some bronchodilatation ,airway opening, in certain individuals. Although not generally the first choice of rescue medicines for acute symptoms, some asthmatics cannot tolerate short acting beta2-agonists and thus an anticholinergic
