Anaphylactic shock occurs rapidly and is life-threatening. It is a systemic, type I hypersensitivity reaction that often has fatal consequences. Anaphylaxis causes the immune system to release a flood of chemicals that can cause a person to go into shock.
Anxiolytic-hypnotics agents are used to alter an individual’s responses to environmental stimuli. These agents are referred to as anxiolytics (prevent feelings of tension or fear), sedatives (help patient feel calm and unaware of their environment), and hypnotics (help patients sleep).
