ATRIAL FIBRILLATION
AF vs ECTOPIC BEATS? Management?
ECTOPIC BEATS- spontaneous, b-blocker if treatment needed
AF- can lead to stroke (blood doesn’t fully eject–> clot)
Use ventricular rate control or sinus rhythm control

The 80 mg dose should be considered only in patients with severe hypercholesterolaemia and high risk of cardiovascular complications who have not achieved their treatment goals on lower doses, when the benefits are expected to outweigh the potential risks.

BLACK TRIANGLE?
The black triangle symbol identifies newly licensed medicines that require additional monitoring by the European Medicines Agency. Such medicines include new active substances, biosimilar medicines, and medicines that the European Medicines Agency consider require additional monitoring. The black triangle symbol also appears in the Patient Information Leaflets for relevant medicines, with a brief explanation of what it means. Products usually retain a black triangle for 5 years, but this can be extended if required.
Spontaneous reporting is particularly valuable for recognising possible new hazards rapidly. For medicines showing the black triangle symbol, the MHRA asks that all suspected reactions (including those considered not to be serious) are reported through the Yellow Card Scheme. An adverse reaction should be reported even if it is not certain that the drug has caused it, or if the reaction is well recognised, or if other drugs have been given at the same time.

You are discussing with the nursing team the number of patients who are coming into the
surgery to get their INR tested due to being on warfarin. As part of a measure to try and
reduce this you identify a cohort of patients who are eligible and willing to switch over to a
DOAC.
One of the nurses asks what a patients INR should ideally be if they are to switch over
to Apixaban from Warfarin straight away?

reduction in risk of complications associated with the insertion of an epidural

Which of the following is the most appropriate use of aspirin?
Prevention of cardiovascular events in a COPD patient who has previously had a

Mr INR is a 62-year-old man who has been prescribed warfarin to treat myocardial infarction.
He has been admitted into hospital with an INR of 10.4 with minor bleeding.
Which of the following is the most appropriate course of action?
Stop warfarin; give phytomenadione (vitamin K1) by slow IV injection; repeat dose of
phytomenadione if INR still too high after 24 hours; restart warfarin when INR <5.0
warfarin
INR>8 minor bleeding?

INR >8.0, minor bleeding—stop warfarin sodium; give phytomenadione (vitamin K1) by slow intravenous injection; repeat dose of phytomenadione if INR still too high after 24 hours; restart warfarin sodium when INR <5.0
INR >8.0, no bleeding—stop warfarin sodium; give phytomenadione (vitamin K1) by mouth using the intravenous preparation orally [unlicensed use]; repeat dose of phytomenadione if INR still too high after 24 hours; restart warfarin when INR <5.0

You explain that sometimes patients require a particular brand. Which one of the
following does this apply to?
The standard formulations containing 60mg diltiazem hydrochloride are licensed as generics and
there is no requirement for brand name dispensing. Different versions of modified-release
preparations containing more than 60mg diltiazem hydrochloride may not have the same clinical
effect. To avoid confusion between these different formulations of diltiazem, prescribers should
specify the brand to be dispensed.

Mr AK has come to your heart failure clinic for a medication review. He has been stable on
the maximum dose of ACE inhibitor and beta-blocker for 8 weeks. However, you notice Mr
AK’s ankles are still swollen indicating his heart failure symptoms have not been adequately
controlled. You decide to refer Mr AK to his specialist for a review of his symptoms, where a
few days later a letter from the heart failure consultant has recommended you initiate the
next phase of heart failure treatment. The consultant has mentioned that Mr AK’s ejection
fraction is <35% and he is at class III of the New York Heart Association classification for
heart failure. Which of the following medications would be the most appropriate to initiate
MR AK’s as step regimen for managing his heart failure symptoms?
Sacubitril/Valsartan

- A 56-year-old female patient attends her GP surgery after developing a cough, having chest pain, and losing her appetite. The GP performs an examination and uses the CRBGS score to diagnose low-severity
community-acquired pneumonia. A course of antibiotics is prescribed
Which of the following treatment options would be appropriate for this patient?
A. A 3-day course of a single antibiotic.
B. A 5-day course of a single antibiotic.
C. A 5-day course of two antibiotics.
D. A 7-day course of a single antibiotic.
E. A 7-day course of two antibiotics.
Answer: B (A 5-day course of a single antibiotic.)
Adults with low-severity community-acquired pneumonia are prescribed a 5-day course of a single antibiotic.
Pneumonia is usually caused by bacteria and should be treated with antibiotic therapy. A 5-day course of a single antibiotic is usually an effective treatment for diagnosed low-severity community-acquired pneumonia unless symptoms do not improve. Prescribing a 5-day course will ensure that antibiotic therapy is not given for longer than necessary, and will contribute to effective antimicrobial stewardship. Healthcare professionals should give people advice on seeking further help if their symptoms do not show signs of improving after 3 days of antibiotic therapy.
STROKE, WARFARIN TO RIVAROXABAN SWITCH
50. Following the procedure, the patient has been considered suitable for a switch to rivaroxaban. The patient’s latest CrCI was calculated to be 78ml/min.
Which of the following doses would you expect the patient to be switched to?
Answer: D {20mg once a day)
- CrCI >50ml/min: 20mg
- Manufacturer advises reduce dose to 15 mg once daily if creatinine clearance 15-49 ml/minute.
BREAST CANCER INCREASES WITH CHC, otheres decrease
IMIPRAMIEN MOST ANTIMUSCARINIC
- An 88-year-old woman has been identified as suitable candidate for a direct oral anticoagulant for the prophylaxis of recurrent pulmonary embolism. To aid compliance, she would prefer the medication to be taken once a day without the need for concomitant food consumption.
EDOXABAN
- Rivaroxaban: The MHRA has received a small number of reports suggesting a lack of efficacy (thromboembolic events) in patients taking 15 mg or 20 mg rivaroxaban tablets on an empty stomach. Healthcare professionals are advised to remind patients to take rivaroxaban 15 mg or 20 mg tablets with food.
- Apixaban dosing is twice a day and may affect compliance
Sotalol?
Sotalol may prolong the QT interval, and it occasionally causes life threatening ventricular arrhythmias (important: manufacturer advises particular care is required to avoid hypokalaemia in patients taking sotalol—electrolyte disturbances, particularly hypokalaemia and hypomagnesaemia should be corrected before sotalol started and during use).
