Drugs that cause HTN

Sympathomimetics: Cocaine, amphetamines, designer drugs

1

Drugs that cause bradycardia

BB, CCB, digoxin, lithium

2

Causes of conjugate eye deviation - towards or away from lesion?

Stroke - towards. Seizure - away.

3

Causes of hemiparesis

Post-ictal, stroke, ICH

4

Drug therapy for the agitated patient

If drug induced, drug withdrawal, or unknown - give benzo (lorazepam, midazolam). If Dementia or psychiatric cause - give antipsychotic (haloperidol).

5

Effect of anticholinergic toxicity on HR

Increased HR

6

Effect of synpathomimetic toxicity on HR

Increased HR

7

Effect of sedative toxicity on HR

Bradycardia

8

Effect of cholinergic toxicity on HR

Variable

9

Oral findings for anti cholinergic, sympathomimetic, sedative and cholinergic overdoses

No oral findings except for with cholinergics you get salivation

Dilated

15

How do pupils look with sympathomimetic toxicity

Dilated pupils

16

How do pupils look with sedative toxicity

Dilated or constricted

17

Way to remember cholinergic toxicity

Dumb bells : diarrhea/diaphoresis, urination, miosis (constricted pupil), bradycardia, bronchorrhea, emesis, lacrimation, salivation/seizures

Also AMS, fasciculation, weakness

28

Cholinergic drugs

Organophosphates, carbamates (pesticides), donepezil (ACEi for Alzheimer's), physostigmine (MG, Alzheimer's, delayed gastric emptying), nerve gas agents

29

Sedatives

Anticonvulsants, barbs, benzos, GHB, methaqualone, etoh
