Lexotan (Bromazepam)

Bromazepam is indicated for anxiety‑related conditions and works within the central nervous system to alleviate excessive worry.

• Anxiety disorders: reduces excessive worry and tension, improving daily functioning.
• Acute anxiety episodes: provides rapid symptom relief for short‑term episodes.
• Preoperative anxiety: calms patients before surgical procedures, facilitating smoother induction.

• Bromazepam acts as a positive allosteric modulator at the γ‑aminobutyric acid type A (GABA‑A) receptor complex. By binding to the benzodiazepine site, it enhances the affinity of GABA for its receptor, increasing chloride ion influx and neuronal hyperpolarization. This potentiation of inhibitory neurotransmission reduces neuronal excitability, producing anxiolytic, sedative, and muscle‑relaxant effects.

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

Common Side Effects

• Drowsiness: feeling of sleepiness or reduced alertness.
• Dizziness: light‑headed sensation, especially when standing quickly.
• Fatigue: general lack of energy or tiredness.
• Impaired coordination: clumsiness or reduced motor control.

Serious or Rare Side Effects

• Respiratory depression: slowed or shallow breathing, particularly with other depressants.
• Severe allergic reaction: rash, itching, swelling, or difficulty breathing.
• Paradoxical aggression: unexpected increase in hostility or agitation.
• Dependence and withdrawal: risk of physical dependence with prolonged use.

When prescribing or dispensing bromazepam, several safety considerations should be observed.

• Individualized dosing: prescribe the lowest effective dose for the shortest duration needed.
• Discontinuation: avoid abrupt cessation; taper gradually under medical supervision.
• Elderly patients: use reduced doses and monitor for increased sedation or falls.
• Concomitant CNS depressants: avoid or limit use with alcohol, opioids, or other sedatives.
• Pregnancy and lactation: assess risks versus benefits before use in pregnant or nursing women.
• Store below 25°C: keep in the original container, protect from moisture and light.

Bromazepam can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Opioids: combined use may cause profound respiratory depression and profound sedation.
• Other benzodiazepines or barbiturates: additive CNS depression increases risk of overdose.
• Alcohol: concurrent consumption enhances sedative effects and impairs coordination.

Moderate Interactions (Monitor Closely)

• Antidepressants (SSRIs, SNRIs): may increase sedation or affect serotonin levels.
• Antihistamines: can augment drowsiness and impair alertness.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): may raise bromazepam plasma concentrations.
