Normison (Temazepam)

• Temazepam acts on the central nervous system to alleviate sleep disturbances associated with insomnia.
• Insomnia (short‑term): helps patients achieve sleep onset and maintain sleep for a limited period.
• Sleep onset insomnia: reduces the time required to fall asleep.
• Sleep maintenance insomnia: decreases nighttime awakenings and promotes uninterrupted sleep.

• Temazepam binds to a specific site on the GABA‑A receptor complex, acting as a positive allosteric modulator. This enhances the inhibitory effect of the neurotransmitter GABA, increasing chloride ion influx and hyperpolarizing neuronal membranes, which leads to reduced neuronal excitability and a sedative‑hypnotic effect.

Common Side Effects

• Drowsiness: feeling unusually sleepy during the day.
• Dizziness: light‑headed sensation or loss of balance.
• Fatigue: general lack of energy.
• Headache: mild to moderate pain in the head.
• Impaired coordination: reduced motor control.
• Memory impairment: difficulty recalling recent events.

Serious or Rare Side Effects

• Respiratory depression: slowed or shallow breathing.
• Severe allergic reaction: rash, swelling, or difficulty breathing.
• Dependence or withdrawal: physical or psychological reliance on the drug.
• Paradoxical agitation: increased anxiety or aggression.
• Depression or suicidal thoughts: mood changes requiring urgent care.
• Hallucinations: visual or auditory disturbances.

• Before prescribing Normison, clinicians should evaluate patient history and potential risk factors.
• Assess hepatic function: adjust use in patients with liver impairment.
• Avoid in severe respiratory disorders: risk of respiratory depression.
• Monitor for signs of dependence: limit duration of therapy.
• Educate about operating machinery: avoid tasks requiring alertness until response is known.
• Store below 25°C: keep in the original pack, protect from moisture.

Temazepam may interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

• Other CNS depressants (e.g., opioids, barbiturates): may cause profound sedation and respiratory depression.
• Alcohol: potentiates sedative effects and increases risk of overdose.
• Antifungal agents (e.g., ketoconazole): can raise temazepam plasma concentrations.

Moderate Interactions (Monitor Closely)

• CYP3A4 inhibitors (e.g., erythromycin, clarithromycin): may modestly increase temazepam levels.
• CYP3A4 inducers (e.g., carbamazepine, phenytoin): may reduce therapeutic effect.
• Antidepressants (e.g., SSRIs, SNRIs): can enhance sedation and dizziness.
