What is xanthine bronchodilator?
Xanthine derivatives are a group of alkaloids that work as mild stimulants and bronchodilators. Xanthine derivatives ease symptoms of bronchospasm and make breathing easier by relaxing the smooth muscles of the respiratory tract and reducing the airway’s hypersensitive response to stimuli.
What are xanthines used for?
The major use of xanthine derivatives are for relief of bronchospasm caused by asthma or chronic obstructive lung disease. The most widely used xanthine is theophylline.
Which of the following is a xanthine bronchodilator?
Xanthines such as theophylline, doxophylline, and aminophylline have been used for many years as treatments for asthma and chronic obstructive pulmonary disease (COPD). They have both bronchodilator and antiinflammatory actions.
How do xanthines work in asthma?
Xanthines inhibit late phase airway reactions induced by allergen or chemical sensitizers. But, they offer little protection against methacholine-, histamine, or allergen-induced immediate bronchoconstriction and any protection seen is unrelated to the extent of the initial bronchodilatation.

What are the classes of bronchodilators?
Classifications of bronchodilators include beta 2-agonists, anticholinergics, and xanthine derivatives. These medications open the airways, but they work on different receptors in the body. Beta 2-agonists stimulate beta-adrenoceptors in the airway.
What is the meaning of Xanthin?

Are xanthine bronchodilators?

How do Xanthines work in asthma?
What is xanthine used for?
Xanthines are sometimes used to treat asthma. Xanthine is an important intermediate in purine degradation, and is subsequently found in most fluids and tissues of the human body. Uric acid is the final product of the breakdown of purines and is normally expelled in urine.
What are the side effects of bronchodilators?
Bronchodilators can have side effects like these: Nervous or shaky feeling. Increased heart rate or palpitations. Upset stomach. Trouble sleeping. Muscle aches or cramps. When should bronchodilators be used? The rescue inhalers are best for treating sudden asthma symptoms.
What to know about bronchodilators?
Bronchodilators are medications that cause the bronchial muscles to relax and, as a result, the bronchial tubes to open wider or dilate. When these muscles relax, the bronchial tubes can usually open fully again and breathing can become normal. We say “usually” because sometimes the bronchial tubes themselves are swollen and filled with mucus.
How to use a bronchodilator inhaler properly?
To prime the inhaler: Unscrew the cover of the inhaler and lift it off.
