Diazepam

Diazepam: Complete Guide with FAQs

Introduction

• Diazepam, commonly known by the brand name Valium, is a benzodiazepine medication.
• It is widely used to manage anxiety, muscle spasms, seizures, and alcohol withdrawal symptoms.
• It acts on the central nervous system (CNS) by enhancing the effects of GABA, a neurotransmitter that induces relaxation and reduces overactivity in the brain.

Class and Mechanism of Action

• Drug Class: Benzodiazepines.
• Mechanism: Binds to GABA-A receptors, enhancing GABA’s inhibitory effects on neuronal activity, leading to sedative, anxiolytic, anticonvulsant, and muscle-relaxant properties.

Indications

• Anxiety Disorders: Short-term management of severe anxiety.
• Seizures and Status Epilepticus: Emergency management of prolonged seizures.
• Muscle Spasms: Relief from acute skeletal muscle spasms due to injury or neurological conditions.
• Alcohol Withdrawal: Reduces symptoms like agitation, tremors, and seizures.
• Premedication for Procedures: Used before surgeries or diagnostic procedures to induce sedation.

Dosage and Administration

• Adults:
  • Anxiety: 2–10 mg orally 2–4 times daily.
  • Muscle Spasms: 2–10 mg orally 3–4 times daily.
  • Seizures: 5–10 mg IV every 10–15 minutes, max 30 mg.
• Children:
  • Seizures: 0.1–0.3 mg/kg IV every 2–5 minutes, max 10 mg.
• Elderly: Start at lower doses (e.g., 2 mg orally), increase gradually.
• Administration: Can be given orally, IV, IM, or rectally. Adjust dosing based on response and indication.

Drug Interactions

• Alcohol and CNS Depressants: Additive sedation and respiratory depression.
• Opioids: Increased risk of respiratory depression.
• Antacids: May reduce diazepam absorption.
• Enzyme Inhibitors (e.g., cimetidine): Increase diazepam levels and prolong effects.
• Enzyme Inducers (e.g., rifampin): Decrease diazepam levels and efficacy.

Monitoring Parameters

Use in Children

• Safe for specific conditions like seizures but requires careful dose adjustment.
• Use the rectal gel formulation for emergency seizure management.

Use in Pregnancy

• Category D: May cause fetal harm; avoid unless the benefits outweigh the risks.
• Use during labor may cause floppy infant syndrome or respiratory depression in the newborn.

Use in Elderly

• Increased sensitivity to diazepam’s effects; start with the lowest effective dose.
• Monitor closely for excessive sedation, confusion, or falls.
