What Are Anticholinergics? Defining Anticholinergics
What is the mechanism of action of anticholinergics?
Anticholinergics work by blocking the activity of acetylcholine, a type of neurotransmitter, in the body.
What are some common side effects of anticholinergics?
Common side effects include dry mouth, blurred vision, constipation, urinary retention, and cognitive impairment.
Can anticholinergics be used to treat allergies?
Anticholinergics may be used in combination with other medications to treat nasal congestion and some other allergy symptoms.
How do anticholinergics work in the body?
Anticholinergics bind to and block acetylcholine receptors in the body, leading to decreased nerve impulses and relaxation of smooth muscles.
Are there any concerns with the long-term use of anticholinergics?
Long-term use has been associated with cognitive impairment and dementia, especially in older adults. Monitoring is necessary.
How do anticholinergics compare to antihistamines in treating allergies?
Antihistamines are generally more effective in treating allergy symptoms than anticholinergics.
What are some examples of anticholinergic medications used for allergies?
Examples include Atrovent (ipratropium bromide) nasal spray and Spiriva (tiotropium inhalation) powder.
Are there any concerns with using anticholinergics for allergies in older adults?
Older adults may be more susceptible to side effects such as cognitive impairment and confusion, so careful monitoring is necessary.
