Pharmacokinetics of theophylline in Guinea pig tears.
It is well recognized that the theophylline (TP) concentration in human tears correlates well with the free TP concentration in human plasma. However this correlation was found only in a very narrow range of concentrations of TP, and pharmacokinetic analysis of TP in tears has not been carried out for a wide range of concentrations of TP. The aims of this investigation were to develop a simple ...
متن کاملEffect of terbinafine on theophylline pharmacokinetics in healthy volunteers.
Twelve healthy volunteers were enrolled in an open-label, randomized, crossover study. Subjects received single doses of theophylline (5 mg/kg) with and without multiple-dose terbinafine, and 11 blood samples were collected over 24 h. The study phases were separated by a 4-week washout period. Theophylline serum data were modeled via noncompartmental analysis. When the control phase (i.e., no t...
متن کاملThe effect of erythromycin on theophylline pharmacokinetics at steady state.
We compared steady-state theophylline pharmacokinetics in 13 healthy adults before and immediately after erythromycin therapy. All subjects received a five-day course of oral aminophylline 3 mg/kg every six hours prior to and during a five-day course of oral erythromycin stearate (1 g daily). Each subject acted as his own control. Multiple serum samples were collected over ten hours following t...
متن کاملUpdate on the pharmacodynamics and pharmacokinetics of theophylline.
Theophylline has emerged as a major prophylactic agent for controlling the symptoms of chronic asthma, but it provides little if any relief of pulmonary symptoms caused by irreversible chronic airways obstruction. Although in vitro it inhibits phosphodiesterase and antagonizes adenosine receptors, theophylline's mechanism of action in asthma is unknown. Often, 10 to 20 micrograms/ml is used as ...
