Pharma Katzung Flashcards
Monoclonal ab that inhibits binding of plt glycoprotein IIb/IIIa to fibrinogen; prevent clotting after coronary angioplasty and in ACS
Abiciximab (also Eptifibatide and Tirofiban)
Antipyretic analgesic with no anti inflamm effect. With less GI distress than aspirin but dangerous in overdose (Hepatic necrosis)
Acetaminophen
Antidote for toxicity: acetylcysteine
Carbonic anhydrase inhibitor diuretic acting in the PCT. produces a NaHCO3 diuresis resulting in bicarb depletion and metabolic acidosis. Self limited diuretic but persistent bicarb depleting actions. Used in glaucoma and mountain sickness
Acetazolamide
Toxicity: paresthesia, hepatic enceph
Antiviral requiring activation by thymidine kinase. Inhibits dna synthesis in HSV and VZV. Toxicity: behavioral effects and nephrotoxicity (crystalluria), minimal myelosuppression
Acyclovir
Miscellaneous anti arrhythmic used parenterally. Hyperpolarizes AV node, blocks conduction for 10-15 s. Used for nodal re entry arrhythmias
Adenosine
Toxicity: hypotension, flushing, chest pain
Rapid acting beta 2 agonist, impt in acute asthma.
Toxicity: tachycardia, arrhythmia, tremor
Albuterol
Others with similar action: metaproterenol, terbutaline
Bisphosphonate; chronic tx with low doses increases bone mineral density and reduces fractures. Higher dose lowers serum calsium. Used in osteoporosis and hypercalcemia in pagets and malignancies
Alendronate
Toxicity: esophageal irritation at low doses; renal dysfunction and osteonecrosis of the jaw in high doses
Irreversible inhibitor of xanthine oxidase, reduce prodn of uric acid. Used in gout and as adjunct in chemotherapy.
Inhibits metabolism of purine analogs (mercaptopurine, azathiopurine)
Allopurinol
- febuxostat is similar
Human recombinant tissue plasminogen activator used to recanalize occluded bld vessels in acute M.I, severe pulmo embolism, and stroke.
Alteplase (t-PA)
- streptokinase is a bacterial protein with thrombolytic properties
Potassium sparing diuretic that blocks epithelial Na+ channels in cortical collecting tubule
Amiloride
Broad spectrum anti arrhythmic that blocks sodium, potassium, calcium channels, and beta receptors. High efficacy and very long half life. Toxicity: deposits in tissues, skin discoloration, thyroid dysfcn, pulmo fibrosis, optic neuritis
Amiodarone
Indirect acting sympathomimetic, displaces stored catecholamines jn nerve endings. Marked CNS stimulation, high abuse liability. Used in ADHD, short term wt loss and narcolepsy
Amphetamine
Tox: psychosis, htn, mi, seizures
Other indir acting: ephedrine, methylphenidate, tyramine
Commonly drug of choice for systemic mycoses. Binds to ergosterol to disrupt fungal cell memb permeability.
Toxicity: chills, fever, hypotension, nephrotoxicity (dose limiting)
Amphotericin B
Activity similar to Pen G plus E. Coli, H. Influenzae, P. Mirabilis, Shigella. Synergy eith aminoglycosides vs enterococcus and listeria. More adverse effects in GIT than other penicillins; maculopapular rash
Ampicillin
Aromatase inhibitor (enzyme converts testosterone to estradiol). Used in estrogen dep breast Ca
Anastrozole
Beta 1 selective blocker: low lipid solubility, less CNS effect. Used for HTN, angina.
Toxicity: asthma, bradycardia, av block, heart failure
Atenolol
*generic names of beta 1 sel A through M except Carteolol, Carvedilol, and Labetalol
Muscarinic cholinoceptor blocker prototype, lipid soluble, with CNS effects. Antidote for cholinesterase poisoning.
Toxicity: red as a beet, dry as a bone, blind as a bat, mad as a hatter, urinary retention, mydriasis
Atropine
Antimuscarinics for ophthalmology that cause cycloplegia and mydriasis
Cyclopentolate, Tropicamide
Antimuscarinic eith decreased CNS effects
Glycopyrrolate
Macrolide similar to erythromycin but greater activity against H. Influenzae, chlamydia, and strep.
Tox: GI distress, no inhibition of drug metabolism
Azithromycin
- clarithromycin: similar with shorter half life and inh drug metab
GABA analog orally active. Actuvates GABA B receptors in spinal cord; spasmolytic
Baclofen
Centrally acting antimuscarinic prototype for parkinsonism
Benztropine
Prototype dopamine agonist in CNS, inhibits prolactin release. Used in hyperprolactinemia and rarely as alternative in parkinsonism
