BACKGROUND Theophylline causes potent cerebral vasoconstriction which decreases blood flow in the non-ischaemic areas of the brain and increases collateral blood flow surrounding the ischaemic region. OBJECTIVE The objective of this review was to assess the effect of theophylline and its analogues

Early reperfusion of brain tissue at risk of injury (penumbra salvage) is crucial in treating acute ischaemic stroke. Neuroprotective agents may extend the time window for the reperfusion. The vasoactive agent theophylline redistributes the perfusion to ischaemic brain tissue and thus

The neurophysiological effects of single-dose theophylline in patients with chronic stroke: A double-blind, placebo-controlled, randomized cross-over study.

Reducing inhibitory neurotransmission with pharmacological agents is a potential approach for augmenting plasticity after stroke. Previous work in healthy subjects showed diminished intracortical inhibition after administration of theophylline. We assessed the effect of single-dose theophylline on

In patients with acute ischemic stroke, dramatic but often transient improvements have been noticed after theophylline injections. Whether better results could be obtained by continuous infusion of the drug was evaluated in a double-blind study. Out of 46 patients with a mean age of 75 years, 22 got

A canine model of theophylline toxicity was used to study the cardiovascular effects seen in severe theophylline poisoning. Eight mongrel dogs were divided equally into two groups. The dogs were anesthetized with pentobarbital and paralyzed with pancuronium bromide. They were ventilated with 100%

To evaluate the chronic effects of theophylline on cardiac function, M-mode and pulsed Doppler derived variables were measured at rest and the suprasternal continuous wave Doppler measurement of ascending aortic flow was used during treadmill exercise testing. Subjects consisted of 13 children with

The cardiovascular effects of theophylline were studied in 11 clinically stable preterm infants. Theophylline was given as aminophylline using a loading dose of 6.8 mg/kg and a maintenance dose of 2 mg/kg every 8 hours intravenously. Cardiac output, stroke volume, and heart rate were measured using

The circulatory effects of plateau plasma theophylline concentrations of 5, 10 and 20 mg/l were examined in normal male volunteers using forearm plethysmography, systolic time intervals and echocardiography. Systemic arterial and forearm venous pressures were not significantly altered during

Sustained-release theophylline compounds given once (Uniphyl) or twice (Theodur) daily were compared in adult asthmatics. Following a single dose of oral medication, large and peripheral airways bronchodilation occurred; response to theophylline correlated significantly with the log plasma

The ambulance was called to a known asthmatic patient. On arrival, the team found a massively dyspnoeic, diaphoretic, non-cyanotic and somnolent patient. His medication consisted of oral theophylline (unknown dosage), fenoterol (metered-dose inhaler), as well as 8 mg oral prednisolone. On the day of
