phenobarbital and Erectile Dysfunction

phenobarbital has been researched along with Erectile Dysfunction in 4 studies

Phenobarbital: A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.
phenobarbital : A member of the class of barbiturates, the structure of which is that of barbituric acid substituted at C-5 by ethyl and phenyl groups.

Erectile Dysfunction: The inability in the male to have a PENILE ERECTION due to psychological or organ dysfunction.

Trial Outcomes

Change From Baseline in Adverse Event Profile (AEP) Score

Adverse Events Profile (AEP) is a 19-item scale used as a systematic measure of adverse effects from antiepileptic drugs (AEDs). Scores range from 19-76; higher scores indicate high prevelance and severity of adverse events. (NCT00522418)
Timeframe: Mean change from baseline AEP Score at 12 months

InterventionUnits on a scale (Mean)
VNS Therapy-6.0
Best Medical Practice-3.2

Change From Baseline in Center for Epidemiologic Studies Depression Scale (CES-D) Score

The Center for Epidemiologic Studies Depression Scale (CES-D) includes 20 items comprising six scales reflecting major dimensions of depression: depressed mood, feelings of guilt and worthlessness, feelings of helplessness and hopelessness, psychomotor retardation, loss of appetite, and sleep disturbance. Possible range of scores is 0 to 60, higher scores indicate more depressive symptoms. (NCT00522418)
Timeframe: Mean change from baseline CES-D Score at 12 months

VNS Therapy-2.2

Change From Baseline in Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) Score

The Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) is a 6-item questionnaire validated to screen for depression in people with epilepsy. Scores range from 6 to 24, with higher scores indicating more depressive symptoms. (NCT00522418)
Timeframe: Mean change from baseline NDDI-E Score at 12 months

InterventionUnits on a Scale (Mean)
VNS Therapy-1.0

Mean Change From Beginning of Intervention Clinical Global Impression-Improvement Scale (CGI-I) Score at 12 Months

The Clinical Global Impression scale (CGI-I) is a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention Scores range from 1-7: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse. (NCT00522418)
Timeframe: Mean change from baseline CGI-I Score at 12 months

Overall Quality of Life in Epilepsy-89 (QOLIE-89) Score in Patients With Baseline & at Least One Post-baseline QOLIE Assessment

QOLIE-89 contains 17 multi-item measures of overall quality of life, emotional well-being, role limitations due to emotional problems, social support, social isolation, energy/fatigue, worry about seizure, medication effects, health discouragement, work/driving/social function, attention/concentration, language, memory, physical function, pain, role limitations due to physical problems, and health perceptions. Range of values 0-100. Higher scores reflect better quality of life; lower ones, worse quality of life. (NCT00522418)
Timeframe: Mean change from baseline QOLIE-89 Overall Score at 12 months

Response Rate

Response Rate is defined as the percent of participants who are responders. A Responder is defined as participants with a reduction of at least 50% or 75% in seizure frequency from baseline to the seizure count evaluation period. (NCT00522418)

Change From Baseline in QOLIE-89 Measures: Subgroup Analysis of Population With Baseline Adverse Event Profile Score < 40

QOLIE-89 contains 17 multi-item measures of overall quality of life. Range of values 0-100. Higher scores reflect better quality of life; lower ones, worse quality of life. Adverse Events Profile (AEP) is a 19-item scale used as a systematic measure of adverse effects from antiepileptic drugs (AEDs).
