Mogadon (Nitrazepam)

• Nitrazepam acts on the central nervous system to produce hypnotic and anxiolytic effects, making it useful for several clinical conditions.
• Insomnia: helps initiate and maintain sleep in adults for short‑term use.
• Anxiety disorders: reduces excessive anxiety symptoms in adult patients.
• Seizure disorders (adjunctive): provides additional seizure control when combined with other antiepileptic drugs.

• Nitrazepam binds to the benzodiazepine site of the GABA‑A receptor complex, acting as a positive allosteric modulator. This enhances the affinity of the receptor for the inhibitory neurotransmitter GABA, increasing chloride ion influx and hyperpolarising neuronal membranes, which results in reduced neuronal excitability and produces sedative, hypnotic, anxiolytic, and anticonvulsant effects.

Nitrazepam may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

• Drowsiness or excessive sleepiness
• Dizziness or light‑headedness
• Impaired coordination or balance
• Memory impairment or concentration difficulties
• Headache
• Fatigue

Serious or Rare Side Effects

• Depression or suicidal thoughts
• Severe allergic reactions (rash, swelling, difficulty breathing)
• Respiratory depression, especially with other depressants
• Paradoxical agitation or aggression
• Skin rash or Stevens‑Johnson syndrome
• Withdrawal symptoms on abrupt discontinuation

• Nitrazepam requires careful use in several clinical situations to minimise risk.
• Pregnancy: Category D – avoid use unless benefits outweigh risks.
• Elderly patients: increased sensitivity – start with the lowest effective dose.
• History of substance abuse: risk of dependence – monitor closely.
• Concomitant CNS depressants: may enhance sedation – adjust dose as needed.
• Driving and operating machinery: may impair performance – avoid until effects are known.
• Store at ambient temperature: keep in original container, protect from moisture and light.

Nitrazepam can interact with other medicines, altering its sedative effect or safety profile.

Major Interactions (Avoid)

• Alcohol: additive central nervous system depression.
• Opioids: may cause profound respiratory depression.
• Other benzodiazepines: cumulative sedation and increased dependence risk.

Moderate Interactions (Monitor Closely)

• Antidepressants (SSRIs, SNRIs): may increase sedation.
• Antihistamines: enhance drowsiness.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): increase nitrazepam plasma levels.
