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 ]
Other mechanisms of action of theophylline have also been proposed. [3] These include the inhibition of nuclear factor-kappaB prevents the translocation of the pro-inflammatory transcription factor (NF-kappaB) to the nucleus, thereby reducing the expression of known inflammatory genes in conditions such as COPD and asthma.
Theophylline (4%): Relaxes smooth muscles of the bronchi, and is used to treat asthma. The therapeutic dose of theophylline, however, is many times greater than the levels attained from caffeine metabolism. [46] 1,3,7-Trimethyluric acid is a minor caffeine metabolite. [5] 7-Methylxanthine is also a metabolite of caffeine.
Theophylline is a non-selective adenosine receptor antagonist. It is also an anti-asthmatic agent and a demethylated metabolite of caffeine. Small open-label trials suggest that theophylline has anti-parkinsonian benefit but a double-blind, placebo-controlled trial did not clearly establish relief from symptoms. [3]
A combination of theophylline, ephedrine, and hydroxyzine has been marketed under the brand name Marax among others as well. [16] [17] [18] Combinations of theophylline, ephedrine, and a barbiturate were later phased out in favor of combinations of theophylline and ephedrine alone (e.g., brand name Franol).

But in the U.S., doctors cannot treat more than 100 buprenorphine patients at a time. Nearly half of all 3,100 counties in America have no doctors certified to prescribe buprenorphine by the Substance Abuse and Mental Health Services Administration and the Drug Enforcement Administration, according to a Huffington Post analysis.
Aminophylline is a compound of the bronchodilator theophylline with ethylenediamine in 2:1 ratio. The ethylenediamine improves solubility, and the aminophylline is usually found as a dihydrate. [2] Aminophylline is less potent and shorter-acting than theophylline. Its most common use is in the treatment of airway obstruction from asthma or COPD.
