Hi cjmca
They are all listed on this website too:
https://www.menopausematters.co.uk/local.phpJust to clarify - maryjane - ovestin contains estriol. The lower concentration cream Orthogynest was replaced by a generic estriol - hence the confusion to patients! Also the generic estriol is weaker than Ovestin but used at 10 times the quanitity so actually the same amount of estriol per dose, I think.
Also estriol is not weaker as such - or rather it has lower affinity to one of the receptors that estradiol (alpha or beta - can't remember which), but binds to the other receptor - both of which are present in the vaginal bladder regions. For this reason and supported by studies, estriol containing products are as effective as those containing estradiol for a significant proportion of women ( according to specific studies). The thing is there are different doses of each - and maybe some of the studies are not comparable eg did they compare 25 mcg vagifem with ovestin for example and at what dose?
The other thing is that the dosage and effectiveness is only worked out as a particular one which is suitable for a significant number of the women studied. This means that there is always a substantial minority of women for whom these dosages or particular products don't work (at that dose or at all sometimes) - and this is where the problems arise and where individualised treatments can be needed.
cjmca - I really liked the old Orthogynest pessaries but these were discontinued. My choice even though I haven't used it, would be the Estring - but depends on the type of bedroom activities you like to indulge in, as certain ones would probably be precluded (not going into details here....) which is why I haven't gone down that route

. I like estriol but can't be doing with messy applicators and washing them out. I have enough to think about with patches twice weekly, T gel daily, progesterone daily now and again and vag oestrogen twice a week without having to do that!
I find that Vagifem works (on the plumping) but does irritate my bladder more.
