what is tibolone and when can it be used
tibolone is a synthetic form of HRT (oestrogen and progestogen) can only be used when a patient is postmenopausal (i.e. >12 months since last bleed)
how is tibolone taken
oral tablet, taken once a day
how does tibolone work?
broken down into two types of oestrogen and one type of progesterone which is strongly androgenic.
It lowers SHBG, increasing free testosterone == androgenic
(as testosterone is bound to SHBG to if we reduce SHBG this means less for testosterone to bind to, increasing free amount of testosterone as bound testosterone has decreased)
what are the main CI to a person taking tibolone
past or current breast cancer (can increase risk of relapse of breast cancer)
caution when using in over 60 year olds as could increase risk of stroke
what menopausal symptoms is tibolone found to be effective at treating?

what is the first gonadotrophin to increase during peri-menopause stage?
FSH
what is the last sex steroid to decrease in menopause
oestradiol
what happens to inhibin A and B during peri-menopause and when?
Inhibin A and B decrease these are the first serological markers to decrease and it starts 2-3 years before the menopause
if a patients FSH is >50 and oestradiol is <20 what does this imply?
cessation of ovarian function
If a patient is age 47 years and still having periods albeit a little irregular what type of HRT would you recommend if wanting to start?
combined sequential HRT
i.e. oestrogen and progesterone/gen
take oestrogen on its own first half cycle and then combined E&P for at least 12-14 days of the cycle. This should give the patient a regular withdrawal bleed
if someone is taking combined sequential HRT at what point do you switch them to continuous combined
if amenorrhoeic or if been on sequential HRT for about 5 years
if a patient attends asking for HRT, they have a uterus and no CI. They tell you that their last period was about 18 months ago. What type of HRT would you start
continuous combined HRT (i.e. E&P together all the time) = should be bleed free!
when can you prescribe continuous combined HRT rather than sequential?
if a patient is postmenopausal i.e. bleed free for >12 months
if taking continuous combined HRT how long can it take for irregular bleeding to settle
up to 6 months
what % of patients taking continuous combined HRT can experience irregular bleeding in the first 6 months
irregular bleeding is common occurrence during the first 6 months (regardless of route of HRT i.e. oral or transdermal), occurs up to 77% of patients, often don’t know why!
what % of patients taking CC HRT after 9 months experience irregular bleeding
3-10%
what proportion of patients discontinue HRT due to irregular bleeding SE
up to 25% of patients
Aileen is taking CC combined HRT. She has been taking it for 3 months and comes to see you as she is worried about some irregular bleeding. Prior to starting HRT she hadn’t had a bleed for > 2 years. She has no risk factors for endometrial cancer. What would you advise?
no need to investigate, reassure if no risk factors can take up to 6 months for bleeding to settle down when just starting on CC HRT.
If bleeding persists > 6 months on CC HRT then investigate with TV USS initially
