When this page of brand names was developed in 1997, there were many fewer varieties of ovarian therapy (ERT/HRT) and no comprehensive listings so I collected the information below the double line. This has some later additions and what is there is correct but as a list it is out of date and incomplete.

For basic information about types of OHT, go to Which OHT?



Important: Before taking any drug, read the patient information sheet which should have been supplied with it.

If you want specific information about a brand name drug, the best thing to do is to consult http://rxlist.com and search on the brand name. 

  • You may get the choice of two links - if you are accessing the (recommended) more comprehensive information linked from the left side of the page, do not overlook the linked blue "tabs" at the top of the screen. 
  • You may find yourself on a generic page but the information will apply equally to the brand name version.
  • Information specific to the UK can be accessed through the British National Formulary which requires free registration. Once registered, you can find info about oestrogens in section 6.4.1.1 and about progestogens at 6.4.1.2 

    Information on oestrogens specific to Australia can be found with some difficulty through http://healthanswers.telstra.com/drugdata/search.asp?SearchLetter=1search_string=O Just look at all entires beginning with oestr. For progestagens, you will have to have the brand name and search from the base page at http://healthanswers.telstra.com/drugdata/

    To find details (including other brand names) of these commonly used agents:

  • estradiol (Climara, Vivelle, Estraderm, Estrace, Estring, Vagifem) then  go to http://www.rxlist.com/cgi/generic/estrad.htm and/or http://www.rxlist.com/cgi/generic2/estradtd.htm (transdermal)
  • conjugated horse estrogens (Premarin) then go to  http://www.rxlist.com/cgi/generic/conest.htm
  • conjugated plant estrogens (Cenestin, C.E.E) http://www.rxlist.com/cgi/generic/cenestin.htm
  • esterified estrogens (Estratab, Menest): http://www.rxlist.com/frame/display.cgi?drug=ESTRATAB
  • ethinyl estradiol http://www.rxlist.com/cgi/generic3/estinyl_ids.htm
  • norethindrone acetate (Aygestin):  http://www.rxlist.com/cgi/generic/norestoc.htm  which refers to contraceptive use but it is the same drug.
  • medroxyprogesterone acetate (Provera, Cycrin) : http://www.rxlist.com/cgi/generic/medrox.htm



  • Incomplete list of BRAND NAMES of ovarian hormones 
    Note that oral dosages are much higher than transdermal ones due to the "first-pass effect" of processing by the liver.
    This greatly reduces the amount available for use and means that direct comparisons of strengths cannot be made.

    MIAMI, FL -- Aug. 10, 1998 -- The United States Food and Drug Administration has approved Rhone-Poulenc Rorer Pharmaceuticals Inc.’s CombiPatch(TM) (estradiol/norethindone acetate), the first hormone replacement therapy (HRT) in the U.S. to deliver a continuous dose of both estrogen and progestogen transdermally via a single patch.
