What is a common use for anticholinergics?

• A. To promote gastrointestinal motility
• B. Decrease oral secretions
• C. Increase respiratory rate
• D. Enhance renal function

Answer: (B)

Anticholinergics are medications that inhibit the action of acetylcholine, a neurotransmitter associated with the parasympathetic nervous system. A common use for these drugs is to decrease oral secretions. This is particularly beneficial in situations where excessive salivation is problematic, such as during surgical procedures or in palliative care settings. By reducing secretions, anticholinergics can help manage drooling and improve comfort for patients.

In addition to their effect on secretions, anticholinergics have other uses, such as treating gastrointestinal disorders and certain respiratory conditions. However, their role in promoting gastrointestinal motility is quite the opposite, as they often slow down movement in the digestive tract. They do not increase respiratory rate; instead, they can help in managing airway secretions but may also decrease respiratory secretions, which is beneficial in specific clinical scenarios. Similarly, anticholinergics do not enhance renal function; their primary uses do not associate with direct renal effects.
