Bromazepam

[9][10][11] Similarly to other intermediate-acting depressants, it may be used as hypnotic medication[12] or in order to mitigate withdrawal effects of alcohol consumption.

[18] Bromazepam is an intermediate-acting benzodiazepine, is moderately lipophilic compared to other substances of its class[19] and metabolised hepatically via oxidative pathways.

In 2003, a team led by Oda Manami at Oita Medical University reported that CYP3A4, a member of the Cytochrome P450 family, was not the responsible enzyme since itraconazole, a known inhibitor of CYP3A4, did not affect its metabolism.

[39] On occasion, benzodiazepines can induce extreme alterations in memory such as anterograde amnesia and amnesic automatism, which may have medico-legal consequences.

[41] Up to 30% treated on a long-term basis develop a form of dependence, i.e. these patients cannot stop the medication without experiencing physical and/or psychological benzodiazepine withdrawal symptoms.

Leukopenia and liver-damage of the cholestatic type with or without jaundice (icterus) have additionally been seen; the original manufacturer Roche recommends regular laboratory examinations to be performed routinely.

Ambulatory patients should be warned that bromazepam may impair the ability to drive vehicles and to operate machinery.

[42][43] In a study about bromazepam's negative effects on psychomotor skills and driving ability, it was noted that 3 mg doses caused minimal impairment.

[47][48][49] Prolonged use of bromazepam can cause tolerance and may lead to both physical and psychological dependence on the drug, and as a result, it is a medication which is controlled by international law.

It is nonetheless important to note that dependence, long-term use and misuse occur in a minority of cases[50][51][52] and are not representative of most patients' experience with this type of medication.

[59][60][61] Animal studies have shown that chronic administration of diazepam (or bromazepam) causes a decrease in spontaneous locomotor activity, decreased turnover of noradrenaline and dopamine and serotonin, increased activity of tyrosine hydroxylase and increased levels of the catecholamines.

[62] Changes in the levels of these chemicals in the brain can cause headaches, anxiety, tension, depression, insomnia, restlessness, confusion, irritability, sweating, dysphoria, dizziness, derealization, depersonalization, numbness/tingling of extremities, hypersensitivity to light, sound, and smell, perceptual distortions, nausea, vomiting, diarrhea, appetite loss, hallucinations, delirium, seizures, tremor, stomach cramps, myalgia, agitation, palpitations, tachycardia, panic attacks, short-term memory loss, and hyperthermia.

[80][81][82] It is marketed under several brand names, including, Brozam, Lectopam, Lexomil, Lexotan, Lexilium, Lexaurin, Brazepam, Rekotnil, Bromaze, Somalium, Lexatin, Calmepam, Zepam and Lexotanil.
