I have chosen to discuss benzodiazepines and in particular, the drug lorazepam. Lorazepam is a type of benzodiazepine which works by binding to the neurotransmitter gamma-aminobutyric acid (GABA) receptors thus increasing the activity of this chemical in the brain which results in calming effects (Drugs.com, 2020).

Lorazepam is used for a variety of medical conditions such as treating anxiety or insomnia due to its sedative properties; it can also be prescribed for other issues like nausea caused by chemotherapy treatments or seizures related to epilepsy(Drugs.com, 2020). Additionally as lorazepam has amnesic effects – meaning it reduces memory formation – it may be recommended pre-operatively for certain surgical procedures that require general anesthesia (Yadav et al., 2017).

Staffing of emergency clinics, centers, and nursing homes is more basic than any time in recent memory as the enormous quantities of ‘people born after WW2’s start to understand the requirement for more continuous clinical mediation and long haul care. Interest in turning into a medical caretaker has disappeared as of late, presumably because of the historical bac
