AZDHS Drug Profiles Flashcards
ASA, acetylsalicylic acid, aspirin - trade name(s)
Bayer, Ecotrin, St. Joseph, others
ASA - class
analgesic, antipyretic, anti-inflammatory
ASA - mechanism of action
in small doses, blocks thomboxane A2, a potent platelet aggregate and vasoconstrictor; this property has led to its use in the acute phase of management of the MI; decreased platelet aggregation
ASA - indications
chest pain or other signs suggestive of AMI; ECG changes suggestive of AMI; unstable angina; pain, discomfort, fever in adult patient only
ASA - contraindications
bleeding ulcer, hemorrhagic states, hemophilia; known hypersensitivity to salicylates or other NSAIDs that has led to hypotension and/or bronchospasm; children and adolescents
ASA - adverse reactions
use with caution in the pt with hx of asthma, other SE are rare with single dose
ASA - incompatibilities/drug interactions
N/A with single dose therapy
ASA - adult dosage
cardiac 160-325 mg (2-4 pediatric chewable tabs) chew or swallow; pain/discomfort/fever 325 mg (4 pediatric chewable tabs) chew or swallow
ASA - pediatric dosage
Not recommended for prehospital use in children
ASA - route of admin
PO
ASA - onset of action
20-30 mins
ASA - peak effects
2 hrs
ASA - duration of action
4-6 hrs
ASA - AZ drug box minimum supply
324 mg
ASA - special notes
heat and light sensitive; the odor of acetic acid (vinegar-like smell) indicates degradation
adenosine - trade name
Adenocard
adenosine - class
antiarrthymic, endogenous nucleoside
adenosine - mechanism of action
slows conduction time through AV node; can interrupt re-entrant pathways through the AV node; slows sinus rate; larger doses decrease BP by decreasing peripheral resistance
adenosine - indications
conversion of supraventricular tachycardias with no known atrial fibrillation or atrial flutter; undifferentiated regular monomorphic wide-complex tachycardia
adenosine - contraindications
sick sinus syndrome, 2nd or 3rd degree AV blocks, except in pt with a functioning ventricular pacemaker; use cautiously in pt with known asthma; pt on theophylline and related methylxanthines, dipyridamole (Persantine) or carbamazepine (Tegetrol); cardiac transplant patients are more sensitive and require only a small dose; known afib or atrial flutter; pregnancy
adenosine - adverse reactions
transient dysrhythmias, palpitations, chest pressure/pain, hypotension, transient HTN, facial flushing, sweating, dyspnea, hyperventilation, tightness in throat, bronchospasm, lightheadedness, headache, dizziness, paresthesias, apprehension, blurred vision, neck-back pain, nausea, metallic taste
adenosine - incompatibilities/drug interactions
not blocked by atropine, theophylline and related methylxanthines (caffeine and theobromine-xanthine) in therapeutic concentrations decrease effectiveness, dipyridamole (Persantine) and carbamazepine (Tegretol, Atretol) block uptake and potentiate effects
adenosine - adult dosage
initial 6 mg rapid IVP, follow immediately with 20 ml NS flush, recommended site is AC (close to central circulation), use injection port nearest hub of IV catheter, arm elevated during procedure, constant ECG monitoring; if no response in 1-2 mins (respectively), may repeat 12 mg utilizing the same procedure
adenosine - pediatric dosage
initial 0.1 mg/kg rapid IVP, follow immediately with 2-3 ml NS flush, use injection port nearest the hub of IV catheter, constant ECG monitoring; if no response, dose may be doubled 1 time (0.2 mg/kg) using same procedure; max single dose not to exceed 12 mg
adenosine - route of administration
rapid IVP
