A

works on water and electrolytes balance- holds water in body whihchraises blood pressure so it used in ppl with lower bp

Q

what are the side effects of mineralcorticoid side effects

memory trick: water retention, Na retention, hypertension

A
Hypertensionsodium retention
water retention
potassium loss
calcium loss
occurs most with fludrocortisone
least seen with betamethasone and dexametasone due to their high glucocorticoid potency

Q

what is adrenal suppression?

what is it caused by the majority of the time

A

adrenal glands do not produce adequate amounts of cortocisteroids primarily cortisol and the mineralcorticoid aldosterone which regullates Na and K and water retention
addisons disease

Q

how do we minimise corticosteroids side effects

A

lowest dose for shortest time
in Morning single dose
local treatment rather than systemic
large volume spacer devices if higher doses required

Q

how is adrenal deficiency treated

A

physiological replacement- combo of hydrocortsione and fludrocortisone- it mimics the bodys natural steroids
provides fludrocrtisone which is aldosterone (a mineralcoticosteroid) and cortisol from hydrsotisone which is a glucocorticoid

Q

which steroid has the highest and second highest glucocorticoid actvitvity
when are they appropriate to use

A

beclometasone
dexametasone
long duration of action
siutable for therapies where fluid retention is not required

Q

high glucocorticoid activity needs minimal mineralcorticoids

A

high glucocoticoid activity only benefit as long as it is accompanied by low mineralcorticoid activity
(this means anti-inflammation therapy with these drugs only works when there is minimal activity trying to retain water such as fludrocotisone

Q

what are the s/e increased risks due to of systemic steroids

A

Blurred vision/disturbance
adrenal suppression- using for a long time, abrupt withdrawal
infection- reduce immune system so increased risk of infectsions
psychiatruc reactions- seek gp to reduce
chicken pox unless they have alrady head - eledlry will have vaccine
measles- avoid exposure

when dom you reduce steroids gradually compard to abruptly

A

Gradual withdrawal for patienst whose disease is unlikely to relapse and have
recieved more than 40mg pred or equivalent daily for overr a week

Q

antithyroid drugs that are not carbimazole or propylthiouracil

A

iodine- adjunct antithyroid drugs avoid long term
radioactive sodium iodide: treatment of thyrotoxicosis
Propanolol: reliefs thyrototoxic symptoms- can be used in conjuction with iodine

Q

what is thyrotoxic crisis (thyroid storm)

how is it treated

A

medical emergency- rapid hr, temp, loss of consciouseness, jaundice, vomiting
I.V fluids
propanolol- blocks conversion of t4 to active form t3
hydrocotisone
oralniodine, carbimazole, propyluthiouracil

25
which antihyperthyroid drugs can be used in pregnancy in a thyroid storm- which trimester
cross the placenta and can cause fetal goitre and hypothyroidism 1st trimester: propylthiouracil not later because it can destroy liver 2nd/3rd trimester: carbimazole and no earlier becuase it can cause brain damage
26
important safety advice with carbimazole
neutropenia and agranulocytosis bone marrow suppression- stop treatment immediately report signs of infections- esp sore throat WBC at any sign of infection stop promptly at any sign of infection
27
what the counselling advice to give with carbimazole
tell dr immediately if sore throat, mouth ulcers, bruising, fever, malaise or non specific illness develops
28
MHRA Advice for carbimazole
acute pancreatitis | congenital defects in first trimester
29
monititoring and advice for propylthiouracil
hepatoxcity- pt look out for signs | stop if liver enzyme problems develo0ps
30
what is hypothyroidism
underproduction of Thyroid hormones | high tsh and low t4
31
signs and symptoms of hypothyrodism
``` fatigue weight gain constipation mesntrual irregularities intolerance to col ```
32
hypothydoism causes
``` iodine deficnecy automine radiotherapty surgery drugs pituitary disorder ```
33
hypothyroid drugs
levothryroxine- drug of choice liothyronine- more rapidly metabolised and more rapid effect. used in more severe hypothyroid states when a rapid response is required.- treatment of choice in hyperthyroid coma
34
indications of hypothyroidism drugs
diffuse goitre hypothroidism thyroid carcinoma
35
risk factors of osteoporosis
``` lifestyle early menopause RA Diabetes history of fractures ```
36
medications used in post menopoausal osteoporosis
oral bisphosphonates- alendronic acid and risedronate- both reduce fractures if contraindicated. use ibandronic acid or desunomab or raloxifene HRT- restricetd to younger post menopausal woomen due to cardiovascular risk and cancer
37
treatment for glucocorticosteroid osteoprosis
glucocorticoid cause bone loss- usually when you start treatment prophylaxis is bisphospohonates
38
list line for osteoporosis in men
oral bisphosphonates 1st line | absorb to crystals in the bone to slow down the process of them breaking dow bone turnover
39
mhra for bisphophonates
2 years plus - atypical femoral fracture- pain in hips thigh, groin so need to report to dr osetonecrosis- pain in jaw- not enough blood goes to jaw- need to maintain good oral hygiene. greater with I.V Oseteonecrosis of external auditory canal: report signs of ear pain, discharge from ear or ear infection
40
side effects for alendronic acid
oesophageal reactions- syphagia, heartburn, pain on swallowing, retrosternal pain report to dr immediately
41
counselling for alendronic acid
swallow whole on single 100ml dose taken on empty stomach 30 mins before breakfast or any other oral med sitting or standing with plenty of water sit or stand upright for 30 minutes after taking the dose
42
what is HRT and what is it used for
uses oestrogen and progestrogen to alleviate symptoms of menopause

44
what age is early menopuse | what age is natural menopause
less than 45 | greater than 50§
45
which hormonal activity does tibolone exhibit
oestrogenic , progestogenic and androgenic activity
46
when is progestrogen given to women with menopause
women with a uterus on long term therapy to reduce risk of endometrial cancer and cystic hyperplasia
47
which causes throboembolism : oestrogen or progestrogen
oestrogen
48
clonidine indication
menopausal symptoms in women who can't take oestrogen but may cause unacceceptable side effects
49
risks from HRT
Breast cancer wndometrial cancer- risk reduced with progesterogen ovarian cancer VTE stroke CHD Benefit outweighs risk for under 60yr olds moment you stop HRT then the riak reduces
50
risk of breast cancer in HRT
all types of hrt increase the risk off the breast cancer within 1-2 years of initiating treatment risk disappears within 5 years of stopping
51
Risk of endometrial cancer in HRT
Depends on dose ad duration cyclically reduces risk of cancer risk eliminated with progestrogen but higher risk of breast cancer
52
which hrt has high risk of stroke
tibolone increaes risk by 2.2 in first year
53
when can oestrogen be given alone
without a uterus unless in endometreosis where you give progestrogen as well
