The potential influence of clopidogrel on the pharmacokinetics of theophylline was evaluated in 15 healthy male subjects during the pharmacokinetic steady state of theophylline, after single and multiple doses. Theophylline was administered orally as one 300-mg capsule in the morning before
Impairments of primary hemostasis are frequently responsible for serious bleeding in sick infants in the neonatal intensive care unit (NICU). Therefore, a rational approach to these infants with hemorrhagic manifestations, in addition to an accurate medical history, a careful physical examination
OBJECTIVE
To determine effects of theophylline therapy for recurrent apnoea of prematurity and abnormal early (within the first 24 hours) cranial ultrasound abnormalities on protective neck turning response in preterm infants.
METHODS
A cross sectional descriptive study.
METHODS
The Neonatal Unit of
To determine the effect of phenobarbital sodium therapy and subependymal intraventricular hemorrhage (SEp-IVH) on the theophylline requirement of premature infants suffering with apnea and seizure activity, we compared three groups of patients as follows: group 1, those with apnea of prematurity
The effect of 7-(2-hydroxypropyl)theophylline (proxyphylline) and coumarin (Theokal) on cerebrocortical NAD/NADH redox state and vascular volume was investigated in cats in haemorrhagic shock. The influence of these drugs on cortical NADH and UV reflectance responses induced by nitrogen breathing
To make a comparison between standard doses of theophylline and caffeine for the treatment of apnea of prematurity.A randomised control trail was conducted in Department of Pediatrics Medicine Govt. Khawaja Muhammad Safdar Medical College and Govt. Allama OBJECTIVE
Oral theophylline treatment may be helpful in controlling severe asthma during pregnancy. This treatment, however, has been suspected of causing both complications and malformations. The objective of this investigation was to study the influence of theophylline treatment on the course of
Chronic hypertension causes the lower and upper limits of CBF autoregulation to reset to higher blood pressure levels. In the present study we examined whether the theophylline derivative P-23, which had lowered blood pressure in SHR, would influence CBF autoregulation. P-23 (10 mg/kg po) was
1. This study was carried out to assess the role of adenosine in the regulation of human erythropoietin (EPO) production. To this end we investigated in healthy volunteers whether the nonspecific adenosine antagonist theophylline increases and the adenosine uptake inhibitor dipyridamole decreases
Prostacyclin (PGI2) infused intravenously into anaesthetized rabbits inhibited electrically-induced thrombus formation in the carotid artery, increased bleeding time and inhibited ex vivo platelet aggregation induced by ADP or arachidonic acid. The increase in bleeding time and the inhibition of ex
The roots of Sophora flavescens (Sf) have been widely used as a herbal medicine for the treatment of diarrhea, gastrointestinal hemorrhage, and eczema. Cytochrome P450 (P450) forms including CYP1A2, CYP2B, CYP2E1, and CYP3A participate in the oxidative metabolism of theophylline, which is an
OBJECTIVE
Plantago major (P. major) is one of the medicinal crops in the world which has therapeutic properties for treatment of respiratory and gastrointestinal diseases. Theophylline is commonly used for the treatment of respiratory diseases. In this study, we investigated the protective effects
Selective stimulation of inhibitory A1 and facilitatory A2a adenosine receptor subtypes located in the nucleus of the solitary tract (NTS) powerfully inhibits cardiopulmonary chemoreflex (CCR) control of regional sympathetic outputs via different mechanisms: direct inhibition of glutamate release
OBJECTIVE
To determine the comparative efficacy of hemoperfusion and hemodialysis for severe theophylline toxicity in concurrent case series.
METHODS
A 10-year, prospective, observational study was performed of consecutive patients referred to a regional poison control center with severe
