Pharmacology - Adenosine, Amiodarone, Oral Glucose, and IM Epinephrine

This set of flashcards covers key concepts related to Adenosine, Amiodarone, Oral Glucose, and IM Epinephrine including their receptors, responses, outcomes, and pharmacokinetics (ADME).

What is the receptor associated with Adenosine in the AV node?

Al receptor in the AV node.

What is the primary response of Adenosine when administered?

AV node hyperpolarizes and conduction stops briefly.

What is the outcome of administering Adenosine?

Re-entry SVT breaks and rhythm resets.

How is Adenosine metabolized?

Destroyed in seconds by enzymes.

How is Amiodarone mainly classified in terms of its effect?

It targets potassium channels primarily.

What is the outcome of administering Amiodarone?

Tachyarrhythmias slow or stop.

What is the absorption property of Amiodarone?

IV known to work fast but has a slow effect.

What is the primary receptor involved in the action of Oral Glucose?

The starving cell sensing glucose at the membrane.

What is the outcome of giving Oral Glucose?

Mental status improves and hypoglycemia symptoms resolve.

What is the absorption characteristic of Oral Glucose?

Slow absorption as it must pass through the GI into the bloodstream.

What is the main receptor type stimulated by IM Epinephrine?

Alpha-1, Beta-1, and Beta-2 receptors.

What is the main response of IM Epinephrine in the body?

Vessels tighten, heart strengthens, lungs open.

How is the metabolism of IM Epinephrine described?
