Lorazepam

Description

Lorazepam

Lorazepam is a benzodiazepine medication primarily used to treat anxiety disorders, insomnia, and certain seizure conditions. It works by enhancing the activity of a neurotransmitter called GABA (gamma-aminobutyric acid), which helps calm the brain and nervous system.

Lorazepam Common Uses:

1. Anxiety Disorders: Short-term relief of severe or disabling anxiety.
2. Insomnia: Particularly when caused by anxiety or stress.
3. Seizures: Emergency treatment of status epilepticus (ongoing seizures).
4. Preoperative Sedation: To relax patients before surgery or medical procedures.
5. Alcohol Withdrawal: Managing symptoms like agitation, tremors, or seizures.

Forms and Administration:

• Tablets (oral use).
• Injection (IV/IM, used in hospitals).
• Liquid Solution (for easier swallowing).

Lorazepam Key Points:

• Onset of action: Fast-acting, with effects felt within 20–30 minutes when taken orally.
• Duration: Effects last 6–8 hours.
• Controlled Substance: Lorazepam 2mg has a potential for dependence and misuse, so it is usually prescribed for short-term use.

3. Elderly Patients:
   • Increased sensitivity; use lower doses to minimize fall and sedation risks.

Drug Interactions

• CNS Depressants:
  • Enhanced sedation with alcohol, opioids, or other sedative medications.
• Valproate:
  • Can increase lorazepam dose for sleep levels by inhibiting metabolism.
• Probenecid:
  • Reduces lorazepam dose for sleep clearance, increasing its effects.

• Take exactly as prescribed; do not increase the dose or frequency without consulting your doctor.
• Avoid alcohol and operating heavy machinery due to sedative effects.
• Do not abruptly stop long-term use; tapering is required to avoid withdrawal symptoms.
• Store in a safe place to prevent misuse or abuse.
• Report any unusual mood changes, confusion, or severe drowsiness to your doctor.
