Diazepam
Enhances action of GABA, an inhibitory neurotransmitter; inhibits spread of electrical activity from irritable focus during seizures, calms CNS. Also a muscle relaxant.
-
Lorazepam

- of electrical activity from irritable focus during seizures, calms CNS.
- Also a muscle relaxant.

Midazolam
- Enhances action of GABA, an inhibitory neurotransmitter; inhibits spread
- of electrical activity from irritable focus during seizures, calms CNS.
- Also a muscle relaxant.

Lidocaine
As an antidysrhythmic, lidocaine suppresses automaticity, excitability, and spontaneous depolarization of the ventricles. As an anesthetic Lidocaine produces local anesthesia by inhibiting transport ions across neuronal membranes, preventing initiation and conduction of normal nerve impulses.
-
Amiodarone
Antidysrhythmic blocking sodium, potassium and calcium channels. It is also a weak, noncompetitive, beta and alpha blocking agent.
-
Adenosine
Decreases impulse formation in the SA node, conduction through the AV node, and depresses left ventricular function. Thus it depresses SA node and AV node activity and interferes with reentrant pathways as well as accessory bypass tracts that cause SVT.
