Uses:
- Insomnia: Helps in reducing the time to fall asleep and increases sleep duration

Nitrazepam enhances the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits activity in the brain. This leads to a calming effect, reduced anxiety, muscle relaxation, and sedation.
Dosage:
- Adults (for insomnia): 5-10 mg before bedtime
- Elderly/Debilitated Patients: Lower doses are recommended due to increased sensitivity

Always follow the prescribed dose from your healthcare provider.
