Exam 1 (Drugs 1 - 50) Flashcards
Hydrocodone bitartrate with APAP
Lortab, Vicodin, Lorcet, Norco
Inhibits prostaglandin synthesis in the CNS & through peripheral action by blocking pain impulse generation
Hydrocodone bitartrate with APAP
Lisinopril
Zestril, Prinivil
Competitively inhibits angiotensin-converting enzyme (therefore causing renin-angiotensin-aldosterone system)
Lisinopril
Use with potassium supplements or other potassium-sparing drugs increases risk of hyperkalemia
Lisinopril
CI in patients with a history of angioedema related to a previous treatment with an ACEI
Lisinopril
Avoid non-prescription cough, cold, and allergy medications unless otherwise directed
Lisinopril
Levothyroxine Sodium
Synthroid, Levoxyl, Levothroid
Exact mechanism unknown but does: regulate growth/development, increase metabolic rate, & inhibit secretion of thyrotropin by the pituitary
Levothyroxine
Relatively CI in patients with uncorrected adrenal cortical insufficiency, untreated thyrotoxicosis, and acute MI
Levothyroxine
Transient loss of hair may be seen in children, but recovery usually occurs
Levothyroxine
Simvastatin
Zocor
A specific inhibitor of HMG-CoA reductase
Simvastatin, Atorvastatin, Lovastatin
This drug may increase warfarin & digoxin levels. CYP3A4 inhibitors in conjunction with this drug can increase risk of severe myopathy or rhabdomyolysis.
Simvastatin, Atorvastatin, Lovastatin
Myopathy could occur with this drug (ex. muscle pain/tenderness); possible photosensitivity; avoid grapefruit juice
Simvastatin, Atorvastatin, Lovastatin
Omeprazole
Prilosec
Proton pump inhibitor (PPI) that suppresses H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell
Omeprazole, Esomeprazole
Since the pharmacological effect of this drug is to raise gastric pH, absorption of drugs in which bioavailability is determined by gastric pH may be changed
Omeprazole, Esomeprazole
Antacids can be used concomitantly with this drug
Omeprazole, Esomeprazole
This drug prevents conversion of clopidogrel to its active metabolite
Omeprazole
Animal studies have revealed increased risk of gastric carcinoid tumors
Omeprazole
Take 30 minutes prior to use; contents of capsule can be opened and mixed with applesauce followed by a glass of water
Omeprazole
Metformin
Glucophage
A biguanide that improves glucose tolerance in NIDDM; decreases intestinal absorption of glucose, suppresses hepatic gluconeogenesis, & improves insulin sensitivity
Metformin
CI in patients with impaired renal function (SCr > 1.5 in males and > 1.4 in females); temporarily D/C therapy when undergoing radiologic studies involving iodine.
Metformin
Decreased vitamin B12 levels, lactic acidosis (characterized by unexplained hyperventilation, myalgia, malaise, or unusual somnolence)
Metformin
Furosemide
Lasix
Loop diuretic which inhibits reabsorption of sodium and chloride in the proximal and distal tubules, but more importantly in the loop of Henle
Furosemide
Can be ototoxic when used in conjunction with AG’s; hypokalemia
Furosemide
CI in patients with anuria
Furosemide, HCTZ
Big AE’s include hearing loss, weakness, muscle cramps, and anemia
Furosemide
Give in the AM to prevent diuresis overnight; avoid overexposure to sunlight; may cause orthostatic hypotension
Furosemide
Potassium chloride (oral)
Klor-Con, K-Dur, Micro-K
The principal intracellular cation of most body tissues. Normal concentrations 3.5 - 5 mEq/L.
Potassium
Use caution with other drugs that may cause hyperkalemia (potassium-sparing diuretics, ACEI’s, salt substitutes)
Potassium
CI in patients with hyperkalemia
Potassium
Take with or after meals and with a full glass of water. Swallow whole but K-Dur can be halved or dispersed in water. Unabsorbable wax matrix may be found in the stool.
Potassium
Gabapentin
Neurontin
Exact mechanism is unknown; exhibits antiseizure activity. Structurally similar to GABA but does not interact with GABA receptors.
Gabapentin
Antacids decrease the bioavailability of this drug when given at the same time
Gabapentin
Do not D/C abruptly due to a possibility of precipitating seizures. Safety and efficacy in pediatric patients < 12 not established.
Gabapentin
Amlodipine Besylate
Norvasc
Calcium channel blocker which inhibits the movement (influx) of calcium ions across specific cellular membranes (slow channels) in vascular smooth muscle and cardiac muscle
Amlodipine
Albuterol Sulfate (inhalation)
Proventil, Ventolin, Proair
Maintenance dose is 2 inhalations QID
Albuterol
Stimulates adenyl cyclase, the enzyme which catalyzes the formation of cAMP from ATP. This formation causes relaxation of bronchial, uterine, and vascular smooth muscle through stimulation of beta-2 adrenergic receptors
Albuterol, DuoNeb
Alprazolam
Xanax
BZD’s facilitate the inhibitory neurotransmitter action of GABA, which mediates both pre- and post-synaptic inhibition in all regions of the CNS
Alprazolam
Citalopram Hydrobromide
Celexa
Blocks the neuronal uptake of serotonin, but not of NE or DA, into human platelets in the CNS (SSRI)
Celexa
Up to 2 weeks may be needed before therapeutic effects are seen; do not abruptly D/C therapy; watch for suicidal thoughts or actions
Celexa
Ranitidine
Zantac
Competitively and reversibly inhibits histamine at the H2 receptors, including receptors on gastric cells
Ranitidine
This drug may decrease the clearance of warfarin and lidocaine
Ranitidine
Zolpidem Tartrate
Ambien
Interacts with the GABA-BZD receptor complex and shares some of the pharmacological properties of the BZD’s
Zolpidem

HydroDiuril, Microzide
Inhibits the reabsorption of sodium and chloride at the distal renal tubule
HCTZ
