Lorazepam's effects are dose-dependent, meaning the higher the dose, the stronger the effects (and side effects) will be. Using the smallest dose needed to achieve desired effects lessens the risk of adverse effects. Sedative drugs and sleeping pills, including lorazepam, have been associated with an increased risk of death. [60]
Also raised were findings in animal studies that showed the development of tolerance in the form of a 15 percent reduction in binding capacity of benzodiazepines after seven days administration of high doses of the partial agonist benzodiazepine drug flurazepam and a 50 percent reduction in binding capacity after 30 days of a low dose of ...
[8] [114] However, they occur with greater frequency in recreational abusers, individuals with borderline personality disorder, children, and patients on high-dosage regimes. [ 115 ] [ 116 ] In these groups, impulse control problems are perhaps the most important risk factor for disinhibition; learning disabilities and neurological disorders ...

[4] Equianalgesic charts are also used when calculating an equivalent dosage of the same drug, but with a different route of administration.
The dose of loprazolam for insomnia is usually 1 mg but can be increased to 2 mg if necessary. In the elderly a lower dose is recommended due to more pronounced effects and a significant impairment of standing up to 11 hours after dosing of 1 mg of loprazolam. The half-life is much more prolonged in the elderly than in younger patients.
Lorazepam can be made using 2-amino-2′,5-dichlorobenzophenone (a derivative of 2-amino-5-chlorobenzophenone), which is first reacted with hydroxylamine, the obtained product is then reacted with chloroacetyl chloride to give 6-chloro-2-chlormethyl-4-(2′-chlorophenyl)quinazolin-3-oxide, a reaction with methylamine produces ring expansion and rearrangement, which forms 7-chloro-2-methylamino ...
