Acetaminophen Classification

Acetaminophen Mechanism Of Action
-Inhibits the synthesis of prostaglandins that may serve as mediators of pain and fever; does not have any significant anti-inflammatory properties.
-Inhibits prostaglandin synthesis in the central nervous system by blocking pain impulse generation.
-Acts on the hypothalamic heat regulating canter to produce peripheral vasodilation resulting in increased blood flow through the skin, sweating, and heat loss.

Acetaminophen Pharmacokinetics
Onset - 15-30 minutes
Duration - 4-6 hours
Acetaminophen EMS Considerations
-Do not administer if the patient has taken the maximum dose of 975mg witching 4 hours.
-If the patient has received less than 975mg witching 4 hours, administer remaining medication to obtain max dose of 975mg.
-Ensure to document patient’s temperature prior to administration.

-Non-steroidal anti-inflammatory drug (NSAID)
Acetylsalicylic Acid Mechanism Of Action
-Blocks the formation of thromboxane A2, which is responsible for platelets aggregating and arteries constricting.
-Producing analgesia and has anti-inflammatory, and antipyretic effects by inhibiting the production of prostaglandins.

Acetylsalicylic Acid Side Effects
-GI irritation
-Nausea / vomiting
-Tinnitus
-Increased risk of bleeding
Acetylsalicylic Acid Pharmacokinetics
Onset - 1-2 hours
Duration - 4-5 hours
Acetylsalicylic Acid EMS Considerations
-Withhold EMS dose if it is confirmed that patient took ASA properly previous to arrival of EMS.
-ASA must still be administered even if patient has taken their daily dose or are on blood thinners.
-Patients taking anticoagulant therapy, ASA may potentiate the effect.
-Diabetics taking ASA and oral hypoglycemic or insulin should be closely monitored for hypoglycemia.
