Valproic Acid Use in Patients With Neurological Disorders

September 28, 2024 updated by: Rehab Werida, Damanhour University

Valproic Acid Use Evaluation in Patients With Neurological Disorders: a Retrospective and Prospective Analysis

Sodium valproate is a well-known anticonvulsant used in the treatment of epilepsy and bipolar disorder, as well as other psychiatric conditions requiring the administration of mood stabilizers. Aim of the present study is to assess sodium valproate usage among patients with neurological disorders.

Prescriptions of 600 patients from out-patient pharmacy of neurology department at Mansoura university teaching hospital were analyzed in a retrospective prospective observational study which conducted between January 2015 and December 2017. Data collected include: demographic data, medical history, drug-drug interaction, polypharmacy, medication error, doses and therapeutic duplication. A designed and structured form was used to collect the required information.

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This quasi-experimental pretest-posttest design study was conducted at the outpatient's pharmacy of Neurology department at tertiary care hospital. After identifying problems with use and completing a follow-up, 3 months of educational intervention (Lectures) among professionals was given. As this study is observational informed consent from all subjects was waived. The subjects were enrolled on the basis of inclusion and exclusion criteria. Patients receiving at least 7 days of Valproic acid, between 10-70 years old, both sexes, were included in the study figure 1. 600 Prescriptions were reviewed between January of 2015 to December of 2017 for patients who were suffering from any psychotic illness and were on psychiatric medications. Then pharmacist educational intervention started and followed up for three months then prescriptions re-evaluted.

Inclusion/ exclusion criteria: The study population was limited to those who were continuously eligible for the outpatient pharmacy refilling thier medications during the entire study period. Patients were identified through pharmacy drug prescriptions By hospital policy all drugs are prescribed for a maximum period of 3 months. Consequently, all patients presented at least twice during the study period. A designed and structured form was used to collect the required information. Data then collected on Microsoft Excel sheet, which included patients' initial therapeutic indications, concomitant use of oral medications, significant adverse drug effects and any drug -drug interaction.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
