Question 1

What is the Meaning of Valproic Acid?

Accepted Answer

Valproic Acid is a pharmaceutical agent primarily classified as an antiepileptic drug and a mood stabilizer. This branched-chain fatty acid, 2-propylpentanoic acid, is fundamental in managing various neurological and psychiatric conditions. Its benefit stems from modulating brain activity.

Question 2

What is the Context of Valproic Acid?

Accepted Answer

Within the central nervous system, Valproic Acid influences neurotransmission. It particularly impacts gamma-aminobutyric acid (GABA), the brain's main inhibitory neurotransmitter. Its presence affects neuronal excitability, making it key in abnormal electrical activity states.

Question 3

What is the Significance of Valproic Acid?

Accepted Answer

This medication holds significant clinical importance for individuals with seizure disorders, including generalized and partial types, and is a core treatment for bipolar disorder. It also serves as a recognized option for migraine prophylaxis. By stabilizing neuronal firing and mood, Valproic Acid helps improve patient quality of life.

Question 4

What is the Mechanism of Valproic Acid?

Accepted Answer

Valproic Acid's therapeutic actions stem from multiple pathways. It increases brain GABA levels by inhibiting GABA transaminase and stimulating GABA synthesis. Additionally, it blocks voltage-gated sodium channels and may modulate T-type calcium channels, reducing rapid, repetitive neuronal firing.

Question 5

What is the Application of Valproic Acid?

Accepted Answer

Clinically, Valproic Acid is available orally as tablets, capsules, or liquid, with an intravenous form for acute needs. Dosing is carefully adjusted to achieve therapeutic serum levels while minimizing side effects, demanding consistent patient adherence. Its use requires understanding individual patient response.

Question 6

What is the Metric of Valproic Acid?

Accepted Answer

Monitoring Valproic Acid involves regular serum drug concentration assessment to maintain levels within the therapeutic range, typically 50-100 mcg/mL. Liver function tests (LFTs), complete blood counts (CBC), and ammonia levels are routinely checked for adverse reactions. Clinical observation of symptom control also guides management.

Question 7

What is the Risk of Valproic Acid?

Accepted Answer

Valproic Acid use carries notable risks, requiring vigilant clinical oversight. Common adverse effects include gastrointestinal upset, tremor, and weight gain. Serious concerns are hepatotoxicity, potentially severe in young children, pancreatitis, thrombocytopenia, and hyperammonemia. Pregnancy use is linked to neural tube defects, requiring careful consideration.
