Anti-asthmatic agents, also known as anti-asthma drugs, refer to drugs that can aid in airway smooth muscle dilation to allow normal breathing during an asthma attack or reduce inflammation on the airway to decrease airway resistance for asthmatic patients, or both. The goal of asthmatic agents is to reduce asthma exacerbation frequencies and ...
Theophylline, also known as 1,3-dimethylxanthine, is a drug that inhibits phosphodiesterase and blocks adenosine receptors. [1] It is used to treat chronic obstructive pulmonary disease (COPD) and asthma. [2] Its pharmacology is similar to other methylxanthine drugs (e.g., theobromine and caffeine). [1]
It belongs to the chemical class methylxanthines (along with caffeine). It is prescribed in severe cases of asthma or those that are difficult to control. It must be taken 1–4 times daily, and doses cannot be missed. Blood tests are required to monitor therapy and to indicate when dosage adjustment is necessary.
Xanthine (/ ˈ z æ n θ iː n / or / ˈ z æ n θ aɪ n /, from Ancient Greek ξανθός xanthós ' yellow ' for its yellowish-white appearance; archaically xanthic acid; systematic name 3,7-dihydropurine-2,6-dione) is a purine base found in most human body tissues and fluids, as well as in other organisms.

Treatment for exercise-induced asthma is similar to other forms of the condition; the main difference is that you will take your medication before exercising as a preventive measure.
Doxofylline (also known as doxophylline) is a phosphodiesterase inhibiting bronchodilator used in the treatment of chronic respiratory diseases such as asthma [1] and COPD. [2] Like theophylline, it is a xanthine derivative. [3] [4]
7-Methylxanthine (7-MX), also known as heteroxanthine, is an active metabolite of caffeine (1,3,7-trimethylxanthine) and theobromine (3,7-dimethylxanthine). [1] [2] It is a non-selective antagonist of the adenosine receptors. [1] [2] The compound may slow the progression of myopia (nearsightedness).
Methylxanthines are chemical compounds which are derivatives of xanthine with one or more methyl groups, including: One methyl group: 1-Methylxanthine; 3-Methylxanthine; 7-Methylxanthine; Two methyl groups: Theophylline (1,3-dimethylxanthine) Paraxanthine (1,7-dimethylxanthine) Theobromine (3,7-dimethylxanthine) Three methyl groups:
