Drugs Flashcards
Nitrates (antianginal)
Dilate coronary arteries and cause systemic vasodilation
- decreased preload
Calcium channel blockers (antianginals)
Dilate coronary arteries and slow heart rate
Beta blockers (antianginals)
Decrease myocardial oxygen consumption by decreasing heart rate
Anticoagulant
Prevents blood clot progression and formation
Antidysrhythmics
Used to treat and prevent abnormal cardiac rhythms
Antihypertensives
Drugs used to treat hypertension
Anytihyperlipidemic agents
Drugs used to treat high cholesterol
What safety category is insulin for pregnant women?
Class B
Classification of insulin
Antidiabetic and hormone
Adverse reactions of insulin
Headache, confusion, fatigue, weakness
Rapid acting insulin
Usually taken before a meal to cover the elevation prior to eating
- taken with longer acting insulin
Short acting or regular insulin
Taken 30 minutes prior to a meal
- used with longer acting insulin
Intermediate acting insulin
Covers the blood glucose levels when rapid and short acting stops working
Glyburide
Promotes insulin release from the beta cells in pancreas
- stimulation by blocking ATP sensitive K+ channels, resulting in Ca2+ influx
- increases peripheral insulin sensitivity
- reduction in hepatic insulin production
Metformin
Insulin sensitized that increases glucose uptake and use by target tissues and decreasing insulin resistance
- differs from Glyburide by not promoting insulin secretion, so there is less risk of hypoglycemia
Opioid triad
Altered LOC
Respiratory depression
Pinpoint pupils (miosis; parasympathetic response)
Crystal meth
Causes vasoconstriction and bronchodilation
Effect on brain is due to norepi and dopamine
Monitor ECG
ASA side effects (3)
Nausea, vomiting, GI upset
Increased risk of bleeds
Tinnitus
Epi side effects (12)
Headache Dizziness Diaphoresis Anxiety Nervousness Syncope Dyspnea Palpitations Tachycardia Hypertension Nausea/vomiting Tremors
