Two xanthine derivatives, aminophylline and enprofylline, were tested on the protective activity of phenobarbital, 20 mg/kg i.p. (60 min before the test) against amygdala-kindled seizures in female rats. Enprofylline, 27.8 mg/kg i.p. (0.143 mmol/kg) 30 min, and aminophylline, 10 mg/kg i.p. (0.043
Electroconvulsive therapy (ECT) is considered to be one of the most effective treatments for patients with major depression and persistent psychosis. Seizure characteristics probably determine the therapeutic effect of ECT; as a consequence, short seizures are accepted as one of the factors of poor
The aim of this study was to evaluate the effects of H(1) (antazoline and astemizole) or H(2) (cimetidine and famotidine) histamine receptor antagonists on the clonic phase, tonic seizures and morality of mice challenged with aminophylline to induce convulsions in mice. Moreover, the total plasma
Aminophylline reversed the protective action of both, D-3-(2-carboxypiperazine-4-yl)-1-propenyl-1-phosphonic acid (D-CPP-ene-a competitive NMDA antagonist) and valproate (used as a conventional antiepileptic drug for comparative purposes) against maximal electroshock-induced seizures. The respective
The mechanism of action of aminophylline in prolonging seizures was tested in amygdala-kindled rats. Aminophylline prolonged the afterdischarge duration of kindled seizures. This seizure-prolonging action of aminophylline was strongly antagonized by the adenosine A1 agonist cyclohexyladenosine and
The aim of this study was to determine the influence of acute (single) and chronic (twice daily for 14 consecutive days) treatments with aminophylline (theophylline(2).ethylenediamine) on the anticonvulsant potential of topiramate (a broad-spectrum antiepileptic drug) in the mouse maximal
Accumulating evidence indicates that aminophylline [theophylline(2) x ethylenediamine] markedly attenuates the anticonvulsant action of conventional antiepileptic drugs in experimental animal models of epilepsy and evokes severe seizure activity in patients treated with this methylxanthine. The
Aminophylline, 285.7 +/- 2.19 mg/kg infused intravenously in unanaesthetized rats produced onset of seizures within 3.2 +/- 0.99 minutes. Seizures were repetitive and death occurred in 10.5 +/- 1.75 minutes. Pretreatment of rats with carbamazepine, sodium valproate and diazepam at doses that
Theophylline-associated convulsions are frequently exacerbated by fever, but the mechanisms behind it are still not completely understood. We investigated whether N-methyl-D-aspartic acid (NMDA) and gamma aminobutyric acid (GABA) receptors are involved in aminophylline
The authors sought to determine whether different responsiveness to seizures induced by aminophylline existed between the genetically epilepsy-prone and normal rats. It was found that the seizure latency was consistently shorter in the genetically epilepsy-prone rats than in normal ones. A different
1. The effects of a chronic treatment with several quinolone derivatives on on the aminophylline-induced convulsions in the genetically epilepsy-prone rat have been investigated. 2. Two series of experiments have been performed: in the first one animals received the quinolone twice a day for 5 days,
Intravenous aminophylline therapy for acute exacerbation of chronic obstructive pulmonary disease may trigger prolonged and difficult to control focal motor seizures with generalization. This can occur in previously neurologically asymptomatic patients and be associated with a poor outcome. Most
BACKGROUND
Aminophylline can trigger seizures in patients without known underlying epilepsy or added risk factor for seizure exacerbation in epilepsy. Most of these seizures are difficult to control and are underappreciated compared to other drug toxicities. Despite a long clinical history of
The present study was undertaken to identify protective drugs against aminophylline (240 mg/kg i.p.)-induced convulsions and lethality in mice. Diazepam (10 mg/kg) and valproic acid significantly prevented the convulsions, but were not effective in preventing mortality. Phenytoin, atropine,
Common antiepileptic drugs and agents affecting different neurotransmitter systems were studied against aminophylline (280 mg/kg i.p.)-induced convulsions in mice. All drugs and agents were administered i.p. Diazepam and phenobarbital antagonized the whole seizure pattern and the respective ED50
