Using a non-invasive cardiac output monitor (Bo-Med NCCOM 3-R7), we have compared cardiovascular responses, degree of haemodilution and incidence of nausea during extradural Caesarean section in healthy non-labouring mothers given either ephedrine 17.5 mg and 3% Dextran 70 7.5 ml kg-1 before delivery (group A) or volume loading with Dextran 15 ml kg-1 without infusion of ephedrine (group B). Sm...

The Drug Enforcement Administration (DEA) is required, as part of the Methamphetamine Epidemic Elimination Act, to develop annual quotas for the manufacture and importation of ephedrine, pseudoephedrine, and phenylpropanolamine products for legitimate utilization in the U.S. At DEA’s request, IMS Health (IMS) identified an approach for generating estimates of 2005 usage for ephedrine and pseudo...

BACKGROUND The present investigation was designed to provide the first empirical examination of the effects of ephedrine sulfate, an alpha- and beta-adrenergic agonist, on subjective and physiological sexual arousal in women. The purpose was to help elucidate the effects of increased peripheral adrenergic activity on sexual response in women. METHODS Twenty sexually functional women participa...

BACKGROUND Recent studies support the use of alpha-agonists during regional anaesthesia in uncomplicated term pregnancies. We hypothesized that ephedrine and phenylephrine, administered for maternal hypotension following fetal hypoxaemia, are equal in respect of fetal outcome. METHODS At 117-132 days gestation, chronically instrumented, anaesthetized and mechanically ventilated ewes were rand...

In this work we demonstrate chiral recognition of (+)- and (-)-ephedrine using a cyclodextrin-containing polymer. The supramolecular structures obtained by complexation of ephedrine and cyclodextrin were verified by 2-D ROESY NMR measurements. Dynamic light scattering showed clear differences in the mean coil size.

UNLABELLED This study evaluated the effect of various beta-adrenergic agonists on (18)F-FDG uptake in brown adipose tissue (BAT) in rats using ex vivo biodistribution studies. METHODS Caffeine (10 mg/kg of body weight, n = 4), ephedrine (5 mg/kg of body weight, n = 4), nicotine (0.8 mg/kg of body weight, n = 9), or a mixture of nicotine and ephedrine (0.8 mg/kg of body weight and 5 mg/kg of b...

BACKGROUND Phenylephrine and ephedrine affect frontal lobe oxygenation ([Formula: see text]) differently when assessed by spatially resolved near infrared spectroscopy. We evaluated the effect of phenylephrine and ephedrine on extra- vs intra-cerebral blood flow and on [Formula: see text]. METHODS In 10 healthy males (age 20-54 yr), phenylephrine or ephedrine was infused for an ∼20 mm Hg incr...

the effect of daily oral administration of ephedrine (0, 1, 2, 4 or 8 mg kg-1 w0.75) on carcasscharacteristics of forty-four 2 yr old crossbred (mehraban x ghezel) fat-tailed ewes was studied. theewes were fed a fattening ration, and received ephedrine by using a drenching gun for either 50 or 70days. there was a significant interaction (p
