Lexaurin (Bromazepam)

Bromazepam belongs to the benzodiazepine class and is used to manage anxiety‑related conditions.

• Generalized anxiety disorder: reduces excessive worry and tension.
• Panic disorder: lessens the frequency and intensity of panic attacks.
• Situational anxiety (e.g., before medical procedures): provides short‑term calming effect.

• Bromazepam acts as a positive allosteric modulator at the GABA‑A receptor complex. By binding to the benzodiazepine site, it enhances the inhibitory effect of the neurotransmitter GABA, increasing chloride ion influx and hyperpolarising neuronal membranes, which results in reduced neuronal excitability and an overall anxiolytic effect.

Bromazepam may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Drowsiness: feeling unusually sleepy or fatigued.
• Dizziness: sensation of light‑headedness or unsteadiness.
• Impaired coordination: reduced motor control and balance.
• Headache: mild to moderate cranial pain.
• Memory impairment: difficulty recalling recent events.
• Fatigue: persistent lack of energy.

Serious or Rare Side Effects

• Depression or suicidal thoughts: mood changes requiring immediate medical attention.
• Respiratory depression: slowed breathing, especially with other CNS depressants.
• Severe allergic reaction: rash, swelling, or difficulty breathing.
• Paradoxical agitation: increased anxiety or aggression.
• Withdrawal seizures: risk if the drug is stopped abruptly after prolonged use.

Bromazepam requires careful use and monitoring to minimise risks.

• Discontinue gradually: avoid abrupt cessation to prevent withdrawal symptoms.
• Hepatic impairment: dose adjustment may be needed in liver disease.
• Avoid alcohol: combined use can intensify sedation and respiratory depression.
• Pregnancy Category D: potential risk to the fetus; use only if clearly needed.
• Elderly patients: increased sensitivity to sedative effects; start with the lowest effective dose.
• Store at ambient temperature: keep in the original container, protect from moisture and light.

Bromazepam can interact with several drug classes, altering its safety profile.

Major Interactions (Avoid)

• Alcohol: additive central nervous system depression.
• Opioids: heightened risk of respiratory depression and profound sedation.
• Other benzodiazepines: cumulative sedative effects.
• Barbiturates: enhanced CNS depression leading to profound sedation.

Moderate Interactions (Monitor Closely)

• SSRIs or other antidepressants: possible increased sedation.
• Antihistamines: additive drowsiness.
• CYP3A4 inhibitors (e.g., ketoconazole): may raise bromazepam plasma concentrations.
