Acetaminophen (APAP)

TRADE NAME

Tylenol

DESCRIPTION

Non-opioid analgesic and antipyretic.

HOW SUPPLIED

Oral Suspension: 160 mg / 5 mL strength

INDICATIONS

CONTRAINDICATIONS

PRECAUTIONS

  1. Monitor for signs of liver toxicity, especially in patients with existing liver conditions.
  2. Be cautious with dosing in patients who are also taking other medications containing acetaminophen.

DOSAGE

Acetylsalicylic Acid

GENERIC NAME

Aspirin

TRADE NAME

Acetylsalicylic Acid

DESCRIPTION

Aspirin works by inhibiting platelet aggregation, which reduces the formation of blood clots. It makes platelets less sticky, helping to prevent clots that can lead to myocardial infarction (MI) or cardiac ischemia.

HOW SUPPLIED

Tablets: 81 mg

INDICATIONS

CONTRAINDICATIONS

PRECAUTIONS

  1. Emergency Medical Dispatch (EMD) protocol allows patients to self-administer aspirin. Verify the amount taken before administering additional doses.
  2. Aspirin may be taken in conjunction with anticoagulants like Coumadin.
  3. Do not administer if there is evidence of active bleeding.

MECHANISM OF ACTION

Aspirin decreases platelet aggregation and reduces inflammation, which helps prevent blood clot formation in the cardiovascular system.

Adenosine

GENERIC NAME

Adenosine

TRADE NAME

Adenocard

DESCRIPTION

Adenosine is a naturally occurring substance present in all cells that slows conduction through the AV node of the heart. Due to its rapid onset of action and short half-life, the administration of Adenosine is sometimes referred to as "chemical cardioversion."

HOW SUPPLIED

Vial and pre-filled syringe: 6 mg/2 mL

INDICATIONS

CONTRAINDICATIONS

MECHANISM OF ACTION

Adenosine decreases conduction of the electrical impulse through the AV node, which can terminate rapid supraventricular arrhythmias such as PSVT. The half-life of Adenosine is approximately 5 seconds.

SPECIAL CONSIDERATIONS

The preferred IV site is the antecubital fossa with an 18 gauge or larger catheter. Administer via the port closest to the IV catheter for rapid delivery.

Glucagon Hydrochloride

GENERIC NAME

Glucagon Hydrochloride

TRADE NAME

None

DESCRIPTION

Glucagon is used to increase blood glucose levels, particularly in cases where an IV line cannot be immediately established. Intramuscular (IM) administration results in a quicker onset than subcutaneous (SQ) and is therefore the preferred route.

HOW SUPPLIED

Vial: 1 mg powder (activated by injection of 1 cc sterile water)

INDICATIONS

CONTRAINDICATIONS

MECHANISM OF ACTION

Glucagon increases circulating blood glucose levels by promoting the breakdown of stored glycogen to glucose. Return to consciousness typically occurs within 5–20 minutes after administration. However, Glucagon may lose its effectiveness if given within the previous 48 hours.

DESCRIPTION

Cyanokit is an antidote for cyanide poisoning.

HOW SUPPLIED

5 gram single-dose vial of dark red crystalline powder

PREPARATION

Without removing the vial from the box, transfer 200 ml of Normal Saline from an IV bag to the 5 gram Cyanokit vial using the transfer spike, filling to the line on the vial. Rock or invert the vial repeatedly (do not shake) for at least 60 seconds. Verify that no particulate matter is present and the solution is dark red. Attach the included IV tubing to the Cyanokit vial. For adults, administer the entire vial by running the IV wide open. For pediatric patients, use the dosing chart below and administer over 15 minutes.

INDICATIONS

CONTRAINDICATIONS

MECHANISM OF ACTION

Hydroxycobalamin has a higher affinity for cyanide than hemoglobin, preventing cyanide from binding to hemoglobin. When cyanide binds to hydroxycobalamin, it is converted into a form of Vitamin B12, which is then excreted harmlessly in the urine.
