Common Drugs Flashcards
Give 3 types of Anticholesterol Drugs?
- Statins
- Fibrates
- PCSK 9 inhibitors
Give an example of a statin
Simvastatin
How do statins work?
They block HMG CoA reductase (an enzyme the liver uses to make cholesterol)
What conditions are statins used for?
Hypercholesterolaemia Diabetes Angina/MI CVA/TIA People at high risk of MI/CVA
What are side effects of statins?
Myopathy Rhabdomyolysis (renal failure, very rare)
Give an example of a fibrate?
Bezafibrate
What condition is fibrates used for?
Hypertriglyceridaemia, low HDL cholesterol
Give 2 examples of PCSK 9 inhibitors
Alirocumab
Evolocumab
What condition are PCSK 9 inhibitors used for?
Familial Hypercholesterolaemia
How do PCSK 9 inhibitors work?
They inhibit the binding of PCSK to LDLR, increasing the number of LDLRs available to clear LDL, thereby lowering LDL-C levels
