Pharmacology Flashcards
1
Q
What is the mode of action of amiodarone?
A
Amiodarone blocks potassium channels, slows the rate of repolarisation, and increases the refractory period.
2
Q
What do statins do?
A
Statins are HMG-CoA reductase inhibitors, widely used to decrease circulating LDL and triglycerides. Statins modestly increase HDL levels.
3
Q
What is the mode of action of clopidogrel?
A
Clopidogrel works by inhibiting the ADP receptor found on platelets, preventing activation and degranulation.
4
Q
How do beta-lactams work?
A
Beta-lactam antibiotics are bactericidal. They inhibit the transpeptidation reaction of bacterial cell wall synthesis
5
Q
How do aminoglycosides work?
A
Aminoglycosides interfere with protein synthesis
6
Q
How do quinolone anitbiotics work?
A
quinolones interfere with DNA synthesis
