Efficacy of Fluoxetine in Reducing Ictal Hypoventilation in Patients With Partial Epilepsy

2014-08-27 03:18:59 | BioPortfolio

Summary

The purpose of this study is to determine the effects of fluoxetine on breathing mechanisms during seizures. Patients with partial epilepsy commonly have changes in their breathing mechanisms during seizures. These changes may increase the risk of serious side effects from seizures, including sudden unexplained death in epilepsy (SUDEP), which affects 2-10 per 1000 patients with epilepsy each year. Fluoxetine (Prozac) may help to stimulate breathing through its actions in the brain and has been shown to improve breathing changes seen with seizures in certain animals. Fluoxetine is in a class of medications called selective serotonin reuptake inhibitors (SSRIs). It works by increasing the amount of serotonin, a natural substance in the brain, at synapses, the junctions at which nerve cells in the brain communicate. Fluoxetine is currently approved by the United States Food and Drug Administration (FDA) for the treatment of patients with Major Depressive Disorder, Obsessive Compulsive Disorder, Bulimia Nervosa, Panic Disorder and Premenstrual Dysphoric Disorder.

Description

Patients who consent to participate in the study will come to the clinic one week prior to the scheduled date of hospitalization in the Epilepsy Monitoring Unit (EMU). At this visit a complete physical examination including vital signs and complete neurological examination, mental status, cranial nerves, motor examination, deep tendon reflexes, sensory examination, coordinator and gait will be performed. Baseline laboratory studies including complete blood count, serum electrolytes, renal and liver function studies and serum pregnancy test for female patients will also be performed. Study medication will be dispensed at this visit.

Patients will be randomized to receive either 20 mg/day of fluoxetine (one pill) or placebo (one pill), to be started one week prior to the scheduled hospital admission date. The dose will be increased to two pills per day on day 1 of hospitalization bringing the total dose of fluoxetine to 40 mg/day in patients randomized to receive this medication. On the day of discharge from the hospital, the study medication will be reduced to 1 pill per day and the patient will be instructed to stop the medication one week following discharge. A follow-up clinic visit for the patient will be scheduled 1 month following hospital discharge, as is the usual protocol for patients undergoing VET at our institution.

Medical and Biotech [MESH] Definitions

A disorder characterized by recurrent focal onset seizures which have sensory (i.e., olfactory, visual, tactile, gustatory, or auditory) manifestations. Partial seizures that feature alterations of consciousness are referred to as complex partial seizures (EPILEPSY, COMPLEX PARTIAL).

A disorder characterized by recurrent partial seizures marked by impairment of cognition. During the seizure the individual may experience a wide variety of psychic phenomenon including formed hallucinations, illusions, deja vu, intense emotional feelings, confusion, and spatial disorientation. Focal motor activity, sensory alterations and AUTOMATISM may also occur. Complex partial seizures often originate from foci in one or both temporal lobes. The etiology may be idiopathic (cryptogenic partial complex epilepsy) or occur as a secondary manifestation of a focal cortical lesion (symptomatic partial complex epilepsy). (From Adams et al., Principles of Neurology, 6th ed, pp317-8)

A localization-related (focal) form of epilepsy characterized by recurrent seizures that arise from foci within the temporal lobe, most commonly from its mesial aspect. A wide variety of psychic phenomena may be associated, including illusions, hallucinations, dyscognitive states, and affective experiences. The majority of complex partial seizures (see EPILEPSY, COMPLEX PARTIAL) originate from the temporal lobes. Temporal lobe seizures may be classified by etiology as cryptogenic, familial, or symptomatic (i.e., related to an identified disease process or lesion). (From Adams et al., Principles of Neurology, 6th ed, p321)

A disorder characterized by recurrent localized paroxysmal discharges of cerebral neurons that give rise to seizures that have motor manifestations. The majority of partial motor seizures originate in the FRONTAL LOBE (see also EPILEPSY, FRONTAL LOBE). Motor seizures may manifest as tonic or clonic movements involving the face, one limb or one side of the body. A variety of more complex patterns of movement, including abnormal posturing of extremities, may also occur.

An autosomal dominant inherited partial epilepsy syndrome with onset between age 3 and 13 years. Seizures are characterized by PARESTHESIA and tonic or clonic activity of the lower face associated with drooling and dysarthria. In most cases, affected children are neurologically and developmentally normal. (From Epilepsia 1998 39;Suppl 4:S32-S41)
