Flashcards - Pharm
Cyclophosphamide
bioactivated DNA purine alkyating agent at Nitrogen-7 - solid tumors, leukemia, lymphomas - Associated with intersticial cystitis –> Mesna
ABVD for Hodgkins Lymphoma
Adriamycin (doxorubicin), Bleomycin, Vinblastin, Dacarbazine
Mesna
Free thiol, reduces toxicity of cyclophoshamide metabolism, protects bladder
Amifostine
thio-based free radical scavenging agent, protects against platinum containing agents (cisplatin)
Digoxin
Na-K ATPase inhibitor - increased intracellular Na+, decreased Na/Ca exchanger, increased intracellular Ca2+
Vasopressin V2 receptor
Gs - Stimulates adenylyl cyclase
Heparin overdose
Protamine sulfate
Leukovorin/folinic acid
mitigates myelosuppression from methrotrexate - “leucovorin rescue”
reversing tPA
aminocaproic acid
Abciximab
binds to glycoprotein recepptor IIb/IIIa on activated platelets, preventing aggregation
Cladribine
purine analog - inhibits adenosine deanimase, DNA strand breaks - hairy cell leukemia
Probenecid
for gout - Inhibits reabsorption of uric acid
Cochicine
for gout - depolymerizes microtubules - GI upset
Ketoconazole
blocks formation of fungal membrane - tinea corporis - has endocrine effect
Fluconazole
Candida, Cryptococcus neoformans
Itraconazole
aspergillosis, candidiasis, blastomycosis, histoplasmosis
Penicillamine
copper chelator - Wilsons disease - also can use trientine
Dimercaprol
arsenic, mercury, gold, lead, antimony
EDTA
lead poisoning
Deferoxamine
iron overload
sodium thiosulfate
cyanide poisoning
amyl nitrate
induces methoglobinemia - Hb has greater affinity for cyanide
fomepizole
ethylene glycol/methanol poisoning
phentolamine
alpha receptor blocker - can counteract epinephrine, cocaine
Methotrexate
irreversibly inhibits dihydrofolate reductase (DHFR) - decreased dTMP, DNA synthesis
Adenosine
prolongs Phase 4 of pacemaker cell, activates K+ channels, inhibits L-type Ca2+ channels
phenoxybenzamine
irreversible alpha1, alpha2 blocker - used before pheochromocytoma removal
ezetamibe
inhibits cholesterol absorption at brush border
milrinone
increases inotropy - phosphoesterase 3 inhibitor - increases cAMP - can cause hypotension
glitazone/thiazolidinediones
pioglitazone, rosiglitazone - insuilin sensitivity from PPAR-gamma transcription factor binding - hepatotoxicity, heart failure, fractures, weight gain, edema
GLP-1 analog
increases insulin, decreases glucagon - nausea/vomiting/pancreatitis - exenatide, liraglutide
DPP-4 inhibitors
increases insulin, decreases glucagon - mild URI/UTIs - linagliptin, saxagliptin, sitagliptin
amylin analogs
decreases gastric emptying and glucagon - nausea/diarrhea
SGLT-2 inhibitor
blocks glucose reabsorption in PCT - UTIs, yeast infections - canagliflozin
misoprostol
PGE analog, abortifascient
Beta-blocker overdose
Glucagon
metformin adverse effects
can cause lactic acidosis, GI upset
doxorubicin
inhibits topoisomerase II resealing - solid tumors, leukemias, lymphomas - dilated cardiomyopathy
Thazides
hyperGLUC (glycemia, lipidemia, uricemia, calcemia)
