General Pharmacology Flashcards
Pharmacology
The study of Drugs, their sources, their characteristics, and their effects
Asprin
medication used to reduce the clotting ability of blood to prevent and treat clots associated with myocardial infraction
When to administer Asprin
patients with chest pain of a suspected cardiac origin. In the event that a heart attack is occurring, asprin reduces the bloods ability to clot and works to prevent the clot formation that causes damage tot he heart.
When not to administer Asprin
Patient has allergies and/or has gastrointestinal bleeding that can be made worse by the administration of Asprin. Follow protocol
Oral Glucose
Form of glucose given by mouth to great an awake patient (able to swallow) with an altered status and history of diabetes
Oxygen
gas commonly found in the atmosphere pure oxygen is used as a drug to treat any patient whose medical or traumatic condition may cause to be hypoxic.
Active Charcoal
powder prepared from charred wood, usually premixed with water to form a slurry. used to treat a poisoning or overdose when a substance is swallowed and is in the patient’s digestive tract. It will absorb some poisons (binds them to the surfaces of the charcoal) and help prevent them from being absorbed in the body
Inhaler
spray device with a mouth piece that contains an aerosol form of a medication that a patient can spray into their airway
Side effects of using an inhaler
increased heart rate,jitteriness
Nitroglycerin
drug that helps dilate the coronary vessels that supply the heart muscle with blood
When not to administer Nitro
if patient has taken anything to treat erectile dysfunction (viagra or similar medications) because of the possibility of a serious negative interaction with these drugs
Epinephrine
drug that helps to constrict the blood vessels and relax passages of the airway. it may be used to counter a severe allergic reaction
Effects of Epinephrine
Increased heart rate and blood pressure commonly occur after its administration
Asthma Pathophysiology
small airways become reactive and constrict resulting in air trapping
TRIGGERS:
exercise, allergens, respiratory viruses, and even asprin and non- steroidal anti-inflammatory drugs (NSAIDs)
Asthma Action of Medication
Albuterol is most commonly used in an inhaler and in nebulizers.
Albuterol act on the (beta2) receptors of the sympathetic nervous system, which results in dilation of the airways
Albuterol acts primarily on the specific receptors meaning their will be limited cardiac effects
