The pharmacokinetic interaction between lansoprazole with phenytoin and ciprofloxacin in healthy male volunteers was evaluated. In two separate experiments, a single dose of 30 mg lansoprazole was administered alone or in combination with phenytoin or ciprofloxacin to 11, respectively 18 healthy volunteers in two stages treatment of study design, separated by a period in which the phenytoin or ...

Abnormal synchronized neuronal discharges mediated by gap junctions have an important role in epileptic seizures. The analysis of anticonvulsant drugs acting on gap junctions is still a priority in epilepsy research. Therefore, the present study was designed to investigate the effect of carbenoxolone, a gap junction blocker, on the anticonvulsant efficacy of phenytoin in pentylenetetrazole kind...

BACKGROUND Phenytoin, one of the most commonly used antiepileptic drug, is associated with a wide spectrum of adverse drug eruptions. It is metabolized by the hepatic microsomal enzymes. The intermediate metabolites are arene oxides which accumulate due to deficiency of the enzyme epoxide hydrolase. These are postulated to be associated with phenytoin induced hepatotoxicity and antiepileptic hy...

OBJECTIVE To examine the effectiveness of topical phenytoin in preserving the skin viability and increasing acceptance rate of autograft. METHODS We conducted this study in the Central Laboratory Animal House of Jordan University of Science and Technology, Irbid, Jordan during the period from September 2004 to June 2005. Forty-two rats were divided into 2 equal groups; full thickness dorsal s...

OBJECTIVES/HYPOTHESIS Impaired postoperative wound healing is the second most common morbidity after synechia formation in endoscopic sinus surgery. The aim of this experimental study was to investigate the potential effects of topical phenytoin on wound healing after nasal mucosal trauma in rats. STUDY DESIGN An experimental study at the Inonu University Faculty of Medicine. METHODS Twenty...

Toxic epidermal necrolysis (TEN) is a severe drug induced type IV hypersensitivity syndrome that can be caused by anticonvulsant drugs, especially the aromatic anticonvulsants such as phenytoin. Most patients with brain metastasis receive whole brain radiotherapy along with anti-edema measures and anticonvulsants either as prophylactic or for symptom control; phenytoin being the most commonly u...

Pancreatic fistulas are among the most devastating complications after pancreatic surgery. Their subsequent development can be lethal. We report two cases of pancreatic fistulas treated with phenytoin. Fistula tract healing consists of several processes, including cell migration and the formation of a new extracellular matrix. Multiple studies have shown that phenytoin can promote wound healing...

Objective(s): Phenytoin is an antiepileptic drug that is used worldwide. The whole-body pharmacokinetics of this drug have been extensively studied using 11C-phenytoin in small animals. However, because of the limited production amounts that are presently available, clinical 11C-phenytoin PET studies to examine the pharmacokinetics of phenytoin in humans have not yet been performed. We aimed to...

OBJECTIVES To perform MRI cerebellum volumetry in patients exposed to phenytoin and to identify factors associated with cerebellar atrophy (CA). METHODS From 100 consecutive epilepsy patients we selected those with phenytoin use for more than 2 months and with MRI scan available for volumetric studies. We obtained cerebellar volumes corrected for total intracranial volume. Volumes below 2 sta...

This study was performed to investigate whether the anticonvulsant phenytoin has neuroprotective effect in a model of hypoxia-ischemia with neonatal rats. The left carotid artery of each rat was ligated, followed by 3 h of hypoxic exposure (8% O2) in a temperature-regulated environment (36 degrees C). Two weeks later, brain damage was assessed by measuring loss of brain hemisphere weight. Pheny...
