BACKGROUND Despite increasing clinical use, there is limited data regarding regadenoson in stress perfusion cardiovascular magnetic resonance (CMR). In particular, given its long half-life the optimal stress protocol remains unclear. Although Myocardial Perfusion Reserve (MPR) may provide additive prognostic information, current techniques for its measurement are cumbersome and challenging for ...

Introduction. Urinary stone is a common cause of urinary tract disease. Stone excretion using ureteroscope is effective in inferior ureter. The aim of this study was to investigate the effects of aminophylline on ureteral spasm during ureteroscopy in acute phase of renal colic. Methods. In this double-blind randomized clinical trial, 120 patients with ureteral stones were enrolled and randomize...

CONTEXT Dyspnea is one of the most common and distressing symptoms that occurs in terminal cancer patients. However, there are no existing treatment guidelines for this condition in China. OBJECTIVE This single-center, retrospective, observational study aimed to compare the efficacy of using morphine, methylprednisolone, or aminophylline to relieve the symptom of breathlessness in patients wi...

15 preterm infants were treated for recurrent apnoea with theophylline. 5 were given oral choline theophyllinate, but this was erratically absorbed. 14 were given IV aminophylline on 23 occasions. Apparent volume of distribution of theophylline in 12 infants was 0.71 +/- 0.18 1/kg (mean +/- SD). Plasma clearance rate measured in 11 infants at steady state was 18.6 +/- 4.8 ml/kg per hour. Calcul...

Physical and chemical stability of suppositories containing aminophylline and various bases prepared in our hospital pharmacy was investigated. Ethylenediamine in aminophylline decreased, the melting points of the suppositories rose, and the disintegration and liquefaction times were prolonged in suppositories with Witepsol base when stored at room temperature. Thin-layer chromatography produce...

SUMMARY The excretion of catecholamines and the changes in plasma concentration of free fatty acids during aminophylline administration were explored. The relationships be tween cardiac arrhythmia, cardiac rate, and change in blood pressure under the conditions of these experiments were defined. Eighteen experiments were performed on eight volunteers. Blood pressures and heart rates before and ...

many premature neonates suffer from apnea, and aminophylline is administrated for them. the objective of this study was to reveal pharmacokinetic (pk) parameters of theophylline in iranian premature neonates. premature neonates (68) who were admitted in the neonatal intensive care unit (nicu) of namazi, hafez, and zeinabieh hospitals were included in the study. all of them received 5 mg/kg amin...

abstract aim and background:   this study is aimed to assess the effect of aminophylline (1mg/kg) on reversal of the sedative effects of propofol and the recovery time in patients under propofol anesthesia. due to the known effects of aminophylline on myocardial contractility and the increase in cardiac output, its effects on hemodynamic changes of propofol are also assessed. methods and materi...
