Pharmacology Flashcards
What 8 medications are in the EMT scope?
Albuterol
Aspirin
Nitroglycerin
Narcan
Oral Glucose
Activated Charcoal
Epinephrine
Oxygen
Sympathomimetic
mimic the effects of the sympathetic nervous system
Such drugs are used to treat cardiac arrest, low blood pressure, or even delay premature labor, amongst other things
Beta 2 agonist
- class of drugs used to treat asthma and other pulmonary disease states
- act on the beta 2 adrenergic receptor
- causing smooth muscle relaxation, resulting in dilation of bronchial passages.
Albuterol
Trade Name
Class of drug
Trade: Ventolin, Proventil
Class: Sympathomimetic, selective beta 2 agonist
Albuterol
Actions
Onset, Duration
- Activates the beta 2 adrenergic receptors to relax smooth muscle
- Bronchodilation, relieves bronchospasms, and reduces airway resistance
Onset = 5 Mins
Duration = 3-4 Hours
Albuterol
Indications
- Respiratory distress with bronchospasms
o Respiratory origin
o Allergic reaction/anaphylaxis
o Pneumonia
Albuterol
Contraindications
- MI
- Cardiac pulmonary edema
- Cardiac dysrhythmias associated with tachycardia (relative, >120) – paramedic is responsible for EKG, paramedic and EMT are responsible for identifying heart rate.
Albuterol
Side Effects
- Restlessness/anxiety
- Vertigo
- Tachycardia/palpations
- Dysrhythmias – paramedic
- Heavy chest (Paradoxical Bronchospasms)
Albuterol
Special Information
- Albuterol may precipitate angina pectoris and dysrhythmias. Check lung sounds, O2 saturation,
- paramedic checks capnography, respiratory rate before and after administration of Albuterol.
Albuterol
Dosage/Route
SVN 2.5 mg in 3 mL of saline @ 6 lpm
* repeat as needed.
* Connect oxygen tubing to SVN and run at 6-8 lpm.
MDI is equal to 90 mcg.

Antiplatelet drugs
Prevent blood clots from forming
Nitroglycerine
Actions
Onset/duration
- Relaxes systemic venous and arterial vessels = vasodilation =
o Decreasing cardiac preload and afterload, myocardial workload, myocardial O2 consumption - Dilates coronary arteries
- SL Onset = 2 min
Topical onset = 30-60 min - SL Duration = 30-60 min
