Question 1

will benadryl (diphenhydramine) have an effect on a methacholine challenge since its a anticholinergic drug?

Accepted Answer

Possibly : To get the best indication of bronchial hyper reactivity, you should not take any antihistamines for 3 to 7 days before the challenge. Unless, of course, the point is to see if Benadryl (diphenhydramine) will diminish the reactivity. That's why you need to discuss  such questions with the physician who ordered the test.

Question 2

what are anticholinergic drugs? and what are the function and side effects?

Accepted Answer

Anticholinergics: Anticholinergics are a class of medication that block muscarinic receptors in the body.  They are typically used to treat over active bladder, or oab.  Common side effects are dry mouth, dry eyes, flushing, urinary retention/difficulty passing urine, confusion (in the elderly, typically), and constipation.

Question 3

why do people with dementia have a greater risk of developing a negative reaction to anticholinergic drugs?

Accepted Answer

They cause confusion: Anticholinergic medications have been known to cause confusion and giving them to people with dementia further increases the confusion they already have. Plus , it causes severe dryness of the mouth, difficulty initiating urination and blurred vision, all these symptoms already present in the geriatric population

Question 4

why do anticholinergic drugs lower your blood pressure?

Accepted Answer

Less vascular tone: The anticholinergic drugs relax the tiny muscles in our arteries, relaxing the arteries and dropping the blood pressure.  They also effect the muscles in our eyes (blurry vision) and that control the ladder and rectum (difficulty with going #1 and #2).

Question 5

ive read that anticholinergic drugs block acetylcholine, causing mental deterioration.is this a concern if you're not eldery? taking amitriptyline 25

Accepted Answer

Proper doses: Taking proper doses of anticholinergic medications should not affect cognitive function in younger patients. Some elderly patients and patients on certain other type medications can be affected.

Question 6

i read that anticholinergic drugs block acetylcholine, causing mental deterioration.is this a worry if you're not elderly?i'm taking amitriptyline 25mg

Accepted Answer

Not to worry: They are only contraindicated in someone with dementia, especially if they are being treated with medications that have the opposite action. Best wishes.

Accepted Answer

Insomnia: Inositol is a vitamin like supplement,  is part of the B family. It has been described as nature's sleeping pill by some. Since the FDA doesn't investigate supplements, most physicians are reluctant to recommend them. Some have contaminants or interact with medications. Your pharmacist may have more information about this supplement and whether it's safe.. My patients did ok with low dose benadryl

Question 8

what is the name of the anticholinergic component & the benzodiazpine component in the drug librax (clinidium and chlordiazepoxide)?

Accepted Answer

Librax (clinidium and chlordiazepoxide): the Benzo is Chlordiazepoxide, &amp; the anticholinergic is Clidinium.

Question 9

between allegra and desloratadine, which drug has less blood-brain barrier permeability and is less anticholinergic?

Accepted Answer

Allegra: Fexofenadine and loratadine, allegra and claritin, respectively, are the least sedating of all anti-histamines according to a recent NIH review.  All anti-histamines cross the blood brain barrier to some extent.  The real issue is sedation and allegra and claritin appear to win the context.  They are also less anticholinergic than many others.

Question 10
