Use of Methylxanthine
Therapies for the Treatment and Prevention of Apnea of Prematurity.
At present, such a mechanism is thought to be the most important for interpreting the change in pharmacokinetic parameters of aromatic antibiotics on the consumption of food; a typical example is the direct interaction of the drug and of methylxanthines
, which enter the organism in great amounts in food [37, 98, 99].
A later study by Saldana, et al, (21) looked at the extraction of methylxanthines
from guarana seeds, mate leaves, and cocoa beans using supercritical carbon dioxide and ethanol.
Fact: In the early 1980s, women with fibrocystic breast disease - a condition characterized by painful but noncancerous breast lumps - were told they could control or cure it by removing from their diets all methylxanthines
, a group of compounds that includes caffeine.
agonists ([beta.sub.2] agonists) and methylxanthines
were measured at 282-nm wavelength.
Previous papers have reported that artificial parthenogenesis in sea stars can be induced--for example, by treatment with thymol or methylxanthine
(Obata and Nemoto, 1984; Washitani-Nemoto et al., 1994).
theophylline is effective in COPD, but is used less often than inhaled bronchodilators because of the potential for toxicity, given its narrow therapeutic index.
Researchers from the National Heart and Lung Institute of the Imperial College, London, examined the effects of theobromine, a methylxanthine
derivative of cocoa, on cough.
Adding inhaled methylxanthine
to initial bronchodilator therapy offered a small benefit in just one of three studies.

Pentoxifylline (PTX) is a methylxanthine
derivative with chemical name of 1-5-oxohexyl-3,7-dimethylxanthine .
