The elderly have less cognitive reserve and are more sensitive to the short (e.g., in between dose withdrawal) and protracted withdrawal effects of benzodiazepines, as well as the side-effects both from short-term and long-term use. This can lead to excessive contact with their doctor.
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 [136] At the 24-week follow-up, 80% of people had successfully withdrawn from benzodiazepines.
These effects may become apparent during continued use or may appear as withdrawal symptoms when dosage is reduced or the drug is stopped. [citation needed] ***Equivalent doses are based on clinical experience but may vary between individuals. [34] ****Etizolam is not a true benzodiazepine but has similar chemistry, effects, and abuse potential.
The prosuicidal effects of benzodiazepines are suspected to be due to a psychiatric disturbance caused by side effects or withdrawal symptoms. [11] Because benzodiazepines in general may be associated with increased suicide risk, care should be taken when prescribing, especially to at-risk patients.
The most common side-effects of benzodiazepines are related to their sedating and muscle-relaxing action. They include drowsiness, dizziness, and decreased alertness and concentration. Lack of coordination may result in falls and injuries particularly in the elderly.
Chlordiazepoxide is generally considered an inappropriate benzodiazepine for the elderly due to its long elimination half-life and the risks of accumulation. [10] Benzodiazepines require special precaution if used in the elderly, pregnancy, children, alcohol- or drug-dependent individuals and individuals with comorbid psychiatric disorders .
Benzoyl chloride, also known as benzenecarbonyl chloride, is an organochlorine compound with the formula C 7 H 5 ClO. It is a colourless, fuming liquid with an irritating odour, and consists of a benzene ring ( C 6 H 6 ) with an acyl chloride ( −C(=O)Cl ) substituent .
Benzyl benzoate is produced industrially by the reaction of sodium benzoate with benzyl chloride in the presence of a base, or by transesterification of methyl benzoate and benzyl alcohol. [8] It is a byproduct of benzoic acid synthesis by toluene oxidation. [11]
