Diphenhydramine is a potent anticholinergic agent and potential deliriant in higher doses. This activity is responsible for the side effects of dry mouth and throat, increased heart rate, pupil dilation, urinary retention, constipation, and, at high doses, hallucinations or delirium.
Effects of anticholinergic drugs include: Delirium (often with hallucinations and delusions indistinguishable from reality); Ocular symptoms (from eye drops): mydriasis, pupil dilation, and acute angle-closure glaucoma in those with shallow anterior chamber [11] [12] [13]
A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting.

New research shows how a surge of anger could raise heart attack risk. Barbara Mantel. Updated May 1, 2024 at 7:25 AM. ... which regulates involuntary processes like heart rate, blood pressure and ...
Organs that receive innervations from these systems include exocrine glands, heart, eyes, gastrointestinal tract etc. Antimuscarinic and antinicotinic agents can increase heart rate, inhibit secretions, and gastrointestinal motility. [1] [2] Naturally occurring antimuscarinics were found in alkaloids from Belladonna (Solanaceae) plants. They ...
A dose–response relationship was established, with larger doses (>170 mg) showing greater increases in heart rate and faster time trials than with smaller doses (≤170 mg) (SMD = 0.85 for heart rate and SMD = -0.24 for time trials, respectively). [20]
This unpredictable aspect of suicide is fraught, complicated and, often, misunderstood − and it's something Nugent feels called to raise awareness about. Isabel Nugent, a gifted student, artist ...
An FAA report found that between 2012 and 2016, diphenhydramine was the most common pharmaceutical known to cause impairment detected in post-mortem toxicology tests performed on someone who may have been in charge of the aircraft at the time of a fatal plane crash, specifically naming both Benadryl and Sominex.
