The symptoms of dizziness, dry mouth, blurred vision, elevated heart rate, and urinary retention are characteristic of an anticholinergic overdose, which includes medications like atropine, antihistamines, and certain antidepressants. These symptoms align with anticholinergic toxicity, which commonly causes central nervous system disturbances (like hallucinations), dry skin, and hyperthermia, among others. The effects on the autonomic nervous system lead to tachycardia and urinary retention. Other listed options can present with some overlapping symptoms but are not characterized predominantly by pronounced anticholinergic effects like dry mouth and blurred vision.
