Midazolam, commonly known by its brand name Versed, is considered the best short-acting medication/anxiolytic for sedating a patient due to its rapid onset and relatively short duration of action. As a benzodiazepine, Midazolam works by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the benzodiazepine receptor site, leading to increased sedation, anxiolysis, and amnesia. This makes it particularly effective in procedural sedation and management of anxiety before surgical interventions or other procedures.

In comparison, other medications listed have different primary uses or are not specifically designed for short-term sedation. Atenolol, for instance, is primarily a beta-blocker used for hypertension and cardiac conditions, lacking sedative effects. Fentanyl is a potent opioid analgesic and, while it can cause sedation as a side effect, it is primarily used for pain management or anesthesia rather than as a first-line anxiolytic. Diazepam, another benzodiazepine, has a longer half-life and may not be suitable for scenarios requiring quick-acting sedative properties. Thus, in settings where short-acting sedation is essential, Midazolam is preferred for its efficacy and rapid action
