A clinically relevant lorazepam dose will normally be effective for six to 12 hours, making it unsuitable for regular once-daily administration, so it is usually prescribed as two to four daily doses when taken regularly, but this may be extended to five or six, especially in the case of elderly people who could not handle large doses at once.
Therapeutic dose dependence is the largest category of people dependent on benzodiazepines. These individuals typically do not escalate their doses to high levels and generally use their medication as intended by their prescriber. Smaller groups include patients escalating their dosage to higher levels and drug misusers as well.
[citation needed] For example, the equivalent dose of diazepam in an elderly individual on lorazepam may be half of what would be expected in a younger individual. [7] [8] Equivalent doses of benzodiazepines differ as much as 20 fold. [9] [10] [11]
A 1991 study indicated that diazepam, in particular, had a greater abuse liability among people who were drug abusers than did many of the other benzodiazepines. Some of the available data also suggested that lorazepam and alprazolam are more diazepam-like in having relatively high abuse liability, while oxazepam, halazepam, and possibly ...
[2] [3] They emphasize deprescribing medications that are unnecessary, which helps to reduce the problems of polypharmacy, drug interactions, and adverse drug reactions, thereby improving the risk–benefit ratio of medication regimens in at-risk people. [4] The criteria are used in geriatrics clinical care to monitor and improve the quality of ...
Improved reaction times were noted at 52 weeks in elderly patients free from benzodiazepines. This is an important function in the elderly, especially if they drive a car due to the increased risk of road traffic accidents in benzodiazepine users. [136] At the 24-week follow-up, 80% of people had successfully withdrawn from benzodiazepines.
Deaths from single-drug benzodiazepine overdoses occur infrequently, [3] particularly after the point of hospital admission. [4] However, combinations of high doses of benzodiazepines with alcohol , barbiturates , opioids or tricyclic antidepressants are particularly dangerous, and may lead to severe complications such as coma or death.
Oxazepam and lorazepam are often used in patients at risk of drug accumulation, in particular, the elderly and those with cirrhosis, because they are metabolized differently from other benzodiazepines, through conjugation. [56] [57]
