CLINICAL- MISCELLANEOUS Flashcards
What is classed as polypharmacy?
4 or more drugs for multiple conditions/ co-morbidities
What’s an example of a common drug patients are left on and they don’t need to be?
PPIs like Omeprazole: question the need!!
What’s the scoring system used in depression?
PHQ2
What medication should we question the need for in patients over 90?
Statins
Reduces 10 year risk of CV disease
Are they going to live this long? Is it worth the side effects?
What is a co-morbidity?
Two long term conditions that accompany eachother e.g diabetes and renal failure
As a pose to multi-morbidity: multiple conditions that don’t really relate to each other e.g. Diabetes and IBS
What’s the problem with clinical trials?
Usually done on people with only one illness (not co morbidities) and very few done on the elderly population
Guidelines: we can use drugs in elderly but with caution as we have to bare in mind they weren’t in the trial
What conditions should beta blockers be avoided in?
Diabetes (mask hypos)
Asthma (constrict airways)
COPD
What’s the problem with aspirin and SSRIS/ TCAs?
Bleed risk
GI irritation
AF can be linked to hypo/hyperthyroidism. How?
Amiodarone is an antiarrythmic Agent used in AF.
Amiodarone can cause hypo or hyperthyroidism.
If it causes hypothyroidism: treat with levothyroxine
If it causes hyperthyroidism: stop the amiodarone
If you stop amiodarone: consider doing TFT (thyroid function test) to see if it gets better
AF can also be caused by hyperthyroidism itself
What can smoking be protective against?
PONV
Ulcerative colitis
Chrons
But it causes COPD, HTN etc..
What must we consider with rheumatoid arthritis and COPD/ asthma?
They are required to use inhalers: but can they do this with their arthritis??
Why are patients with parkinsons and dementia an issue??
They have conflicting pharmacology. The drugs in dementia can cause parkinsons symptoms and the drugs in parkinsons can worsen dementia
Why could diabetes cause depression? How should we manage these?
Diabetes causes neuropathic pain which can lead to depression
Kill two birds with one stone:
Amitryptyline: Use the depression dose and hope it works for the neuropathic pain too
(But SSRIS preferred in depression citalopram, sertraline so patient could end up on both!)
What’s the issue with diabetes, idiopathic thrombocytopenia (increased platelets) and leg ulcers?
Side effect of idiopathic thrombocytopenia treatment is leg ulcers
But it may be deemed to be from diabetes so patient doesn’t get taken off the treatment causing it!
What is the deal with ACE inhibitors and renal function? When are they protective? When are they not?
ACEi: dilate the vessel that leaves the kidneys, therefore they reduce pressure in the kidneys. In the long term, in diabetes, this is protective so could be used as the anti hypertensive of choice in diabetics!
But in the short term, if you suddenly reduce the blood pressure in the kidneys with an ACE inhibitor, you can reduce glomerular filtration.
Therefore you shouldn’t use ACEi in patients with renal impatient and they will reduce eGFR even further.
If a patient is on an ACEi and their renal function drops by 20% of the original function: stop the ace inhibitor!
This is why we have to monitor renal function in people on ACEi’s: make sure we don’t get a sudden change in renal function as a result of initiation or dose change.
At what point should we stop an ACE inhibitor in terms of renal function?
If renal function drops by 20% of their original function after initiation or a change in dose of the ace inhibitor.
This is why we monitor renal function with ace inhibitors!!
What’s the deal with Metformin in renal disease?
Metformin is contraindicated in renal impairment.
Review need if renal function is less than 45
Do not use if renal function is less than 30
So it IS an option, Metformin is currently being under used, but we need to be careful
What co morbidity do we often see with diabetes?
Hypertension!!
Neuropathic pain
Sometimes depression due to neuropathic pain
What co morbidity do we often see with Heart Failure?
Hypertension
Also myocardial infarction and AF
A lot of people in the country take antidepressants. They are over prescribed too often. What’s the problem here?
Antidepressants offer little benefit for most people with mild to moderate depression
Just another drug people don’t necessarily need contributing to Poly-pharmacy.
Non drug therapies such as CBT and mindfulness have more to offer in these patients
What is the risk of TCAs (antidepressants)?
Cardiovascular risk!!
