Talk:Theophylline

message: * Is theophyline naturally derived from plant sources, or is it synthesized in test tube?
** Both. There's no difference between natural and artificial theophylline - they're 100% exactly the same.12:12, 10 Nov 2004 (UTC)
thread_title: Is theophyline naturally derived

message: Recent research at Imperial College London under Prof Peter Barnes has demonstrated that low doses of theophylline raise the level of the enzyme HDAC2, which may then allow glucocorticoids to reduce lung inflamation, which they are not normally effective at with COPD patients. The doses used in the trials were much less than used when theophylline was once a commonly prescribed bronchodilator for COPD treatment.
:Steroids are normally quite effective in COPD patients. Theophylline is still in fairly common use in patients refractory on short- and longterm bronchodilators and inhaled steroids. JFW | T@lk 17:08, 7 March 2006 (UTC)

message: From the article: 'Bioavailability is 100%. However, taking the drug late in the evening may slow the absorption process, without affecting the bioavailability. Taking the drug after a meal high in fat content will also slow down the absorption process, without affecting the bioavailability. There is one exception. Taking UniphylTM, a long-acting theophylline formulation, after a meal high in fat content will increase its bioavailability.'
I am completely ignorant of what bioavailability means, but I'm guessing that it isn't supposed to exceed 100%, making this a rather curious statement, since it implies > 100% bioavailability w/ the use of some product. --anonymous, 31 March, 2008  —Preceding unsigned comment added by 75.172.48.115 (talk) 17:44, 31 March 2008 (UTC)

message: I have had acute extreme tachycardia and elevated BP twice from accumulated cocoa, presumably due to theophylline toxicity, and both times it was reversed starting in 10 minutes and completely in 2 hours with 50 mg orally chewed atenolol. In other words, as the reference in the article says, cardioselective beta blockers do work. Note that a drug such as atenolol of course won't address any CNS issues. --IO Device (talk) 18:11, 11 July 2015 (UTC)
