What is the dose for rivaroxaban in patients with DVT/PE?
15mg BD (twice daily) for 21 DAYS then 20mg OD (once daily)
Eplenerone and amiodarone dose adjustment
max 25mg
- Eplerenone is primarily metabolized by CYP3A4
- amiodarone is a potent CYP3A4 inhibitor
- increase eplerenone levels, necessitating a dose adjustment.

Dypirimadole
Levothyroxine counselling: initial dosing
- If metabolism increases too rapidly (causing diarrhoea, nervousness, rapid pulse, insomnia, tremors and sometimes anginal pain where there is latent myocardial ischaemia),
- reduce dose or withhold for 1–2 days and start again at a lower dose.
How many days should you STOP clopidogrel prior to elective surgery?
7
What calcium channel blocker is commonly prescribed for raynaud’s syndrome?
Nifedipine
What effect does drinking grapefruit juice have on plasma levels fo CCBs?
