In an open, multicentre study, transdermal administration of oestradiol (E2) by means of skin patches was investigated in a Finnish patient population suffering from typical post-menopausal symptoms. A total of 249 women applied a patch twice weekly for 6 months. Whereas 85% of the subjects were experiencing hot flushes and 83.5% sweating before therapy, only 5.7% and 11.8%, respectively, reported these symptoms at the end of the trial. Furthermore, 97.6%, 95.7% and 94.8% of the subjects reported that depression, headache and sleep disturbances, respectively, had disappeared during therapy. Skin irritation occurred in 18.2% of these predominantly fair-skinned women. Frequent sauna bathing did not interfere with the patch therapy. General acceptance of the treatment was excellent, 84.8% of the patients completing the treatment, of whom 78% were willing to continue the treatment after the trial. These results show that transdermal administration of E2 is effective in relieving post-menopausal symptoms. Local tolerability was good and the majority of the patients considered the transdermal treatment to be superior to their previous oral replacement therapy.

The neuroendocrine and clinical effects of transdermal 17 beta-estradiol (rated at 50 micrograms/day; TTS 50) were studied in 40 postmenopausal women; ten additional postmenopausal women did not receive any drugs. The changes in LH and rectal temperature induced by the infusion of the opioid antagonist naloxone (10 mg i.v. bolus plus 10 mg/h for 4 h) were used to evaluate the central activity of endogenous opioid peptides. TTS 50 increased opioid activity, as evidenced by the restoration of the LH response (P less than 0.01) and the enhancement of the hypothermic effect (P less than 0.05) of naloxone. A greater reduction in hot flushes was observed in TTS 50-treated subjects than in untreated women, with the maximal effect of TTS 50 achieved after 3 months of therapy. TTS 50 did not modify the concentrations of circulating lipids, glucose or liver enzymes but reduced the biochemical parameters indicative of bone reabsorption. Bone density of the distal radius significantly increased during TTS 50 (P less than 0.02), reaching its maximum value after 6 months of therapy. Thereafter bone density declined, but more slowly than in untreated women. Our data suggest that TTS 50 has marked neuroendocrine effects, that it diminishes the incidence of hot flushes and reduces bone demineralization. By contrast, it has a very little, if any, metabolic impact on the liver or on glucose and lipid metabolism.

Remifemin is an ethanolic extract of the rhizome of Cimicifuga racemosa (C.r.) and is used to relieve climacteric hot flushes. In the present study the effects of this preparation on LH and FSH secretion of menopausal women were investigated. After an 8 weeks treatment, LH but not FSH levels were significantly reduced in patients receiving the Cimicifuga extract. To further characterize the endocrinologically active principles of this plant extract, a lipophilic extract of C.r. was prepared and subjected to Sephadex chromatography. Fractions obtained were tested for their ability to reduce LH secretion in ovariectomized (ovx) rats and to compete in vitro with 17 beta-estradiol for estrogen receptor binding sites. Three types of endocrinologically active compounds were obtained: (1) Constituents which were not ligands for the estrogen receptor but suppress LH release after chronic treatment, (2) constituents binding to the estrogen receptor and also suppressing LH release, and (3) compounds which are ligands for the estrogen receptor but without an effect of LH release. It is concluded that the LH suppressive effect of C.r. extracts observed in menopausal women and ovx rats is caused by at least three different synergistically acting compounds.

Cyproterone acetate is a progestational antiandrogen with potent antigonadotropic activity that results in rapid suppression of serum testosterone. Used as a single agent, cyproterone acetate yields a total androgen blockade. It may be combined with low-dose diethylstilbestrol, orchiectomy, or LHRH agonists to improve, in theory, the results of such therapy. In clinical testing, cyproterone acetate has proved equivalent to diethylstilbestrol with markedly less toxicity. It is useful in conjunction with LHRH agonists, either transiently to block the flare phenomenon, or continuously to block peripheral androgen receptors; the necessity for this latter action has not yet been proved. Cyproterone acetate may afford transient objective improvement in patients not responding to other forms of hormone deprivation. Experience in this role is limited. The drug may be used to suppress the hot flushes associated with orchiectomy or LHRH agonist therapy. Cyproterone acetate induces local tumor regression; owing to its reversible effects, it is useful as neoadjuvant or adjuvant androgen withdrawal therapy in patients with lower-stage disease undergoing radical surgery or radiotherapy. Adverse effects are mostly those related to hormone withdrawal, namely, impotence, infertility, and lassitude. Gynecomastia and breast tenderness occur in less than 18% and cardiovascular complications in approximately 10% of treated men.

Bleeding and climacteric symptoms were recorded in two groups of postmenopausal women receiving either continuous combined estradiol and norethisterone acetate or estradiol and cyproterone acetate. Out of a sample of 99 postmenopausal women aged 45 to 54 years, 86 completed a 2-year, double-blind, placebo-controlled study. Comparison of the bleeding patterns in the two groups revealed a statistically significant difference: More women in the estradiol-cyproterone acetate group experienced bleeding and for a longer duration. Thirteen women in the estradiol-norethisterone acetate group were amenorrheic, compared with two in the other group. The Kupperman index score in both groups declined to about 30% to 40% of initial values (p less than 0.001). The hot flushes in both treatment groups decreased to a highly significant degree (p less than 0.001), to a value below 20% of baseline values. We conclude that a continuous combination of estrogen and progestogen can produce amenorrhea and symptomatic relief. However, the progestogen components seem to differ in their ability to control bleeding.

For almost a century surgical castration represented the initial standard therapy for metastatic breast cancer in premenopausal women with hormone dependent tumors. Today the suppression of ovarian function can also be obtained by the administration of supraphysiologic doses of luteinizing hormone releasing hormone (LHRH) agonists. From April 1987 to February 1989, 23 premenopausal patients with advanced breast cancer (median age 39 years, range 28-52, ER positive 20, unknown 3; prior chemotherapy 17) were treated with the LHRH agonist goserelin depot (Zoladex) at the dose of 3.6 mg. every 4 weeks. Twenty-two patients were evaluable. Serum levels of 17 beta estradiol, progesterone, FSH and LH were suppressed by goserelin and fell to postmenopausal values within 8 weeks of therapy in 77% of cases. Complete response (CR) plus partial response (PR) was documented in 7 of 22 (32%) and occurred in all major sites of disease. Five patients achieved CR (soft tissue 3, viscera 2). Response rate was higher in patients not previously treated with chemotherapy (4/6). In the present series, all responses were seen in women greater than 35 years old, regularly menstruating at the start of treatment. Time to progression for the entire case series was 22 weeks and for responders 64 weeks. Oophorectomy was performed after disease progression in four patients without success. Goserelin was well tolerated. Local cutaneous dyschromia occurred in 45% and hot flushes in 82%. Treatment efficacy of goserelin is comparable to that of oophorectomy, without the psychological trauma and the morbidity related to surgical castration.

The medical management of endometriosis depends on the stage of the disease, the severity of symptoms, the age of the patient, and her future fertility intentions. The most widely utilized treatment modalities are expectant management, surgery, induction of a pseudopregnancy state with hormonal therapy, and induction of a pseudomenopausal state. Over 50% of women with mild endometriosis and 25% of those with moderate disease can conceive without surgical or pharmacologic intervention. Total hysterectomy or bilateral salpingo-oophorectomy represent the only curative form of treatment, but definitive surgery is recommended only in women who do not want to retain their reproductive function or in whom all previous medical and surgical efforts have failed. Pseudopregnancy therapy (administration of low-dose combined oral contraceptives or medroxyprogesterone acetate) eliminates cyclical changes in the endometrium and bleeding, but is associated with the side effects common to these agents and carries a 5-10% annual recurrence rate. During the 1970s, induction of a pseudomenopausal state through administration of oral danazol was the treatment of choice. In dosages of 100-800 mg day, danazol produces symptomatic improvement in 70-95% of patients and disease regression in 8595%; however, recurrence rates as high as 30-40% have been reported, and weight gains of 20-30 pounds are common. Recent studies have shown the gonadotropin releasing hormone agonist nafarelin to be as effective as danazol or combined oral contraceptives for the treatment of endometriosis. Hot flashes are the most common adverse effect, but are tolerated by the majority of patients. Nafarelin has the additional advantage of not requiring intramuscular injection or monthly office visits, but patients must be given detailed instructions about its intranasal administration.

Progestogen treatment is associated with a number of subjective symptoms. In the present study, 148 healthy post-menopausal women suffering from mild climacteric symptoms were randomly allocated to 12 weeks of treatment with (a) 2 mg oestradiol valerate combined with cyproterone acetate, medroxyprogesterone acetate or levonorgestrel; (b) 1.5 mg 17 beta-oestradiol combined with desogestrel; or (c) placebo. Climacteric symptoms, Kupperman index scores and potential adverse progestogen effects were recorded before treatment and three times per month during therapy. All the hormone regimens had a rapid effect, reducing the severity of climacteric symptoms to about 30% of the baseline values (P less than 0.001) within one month. Hot flushes were reduced in severity and/or frequency by 76 100% within 3 months (P less than 0.001). The regimens which included hydroxyprogesterone derivatives produced a transient increase in breast tenderness. Other recorded potential adverse progestogen effects showed no significant changes during the study. We concluded that the addition of progestogens (whether 19-nortestosterone or hydroxyprogesterone derivatives) does not produce significant side effects during combined hormone replacement therapy.

The authors examined the effect and tolerability of buserelin in 40 women with endometriosis and ten women with uterine leiomyoma. Buserelin was given intranasally, 200 micrograms three times a day for 6 months. Laparoscopy was performed before and after, and ultrasonography during the treatment. Hormone and lipid profiles and other biochemical tests were run during the treatment. The bone mineral density was tested by dual photon absorptiometry before and after therapy in a group of patients. Although most of the patients complained of hot flushes, no women dropped out. AFS mean pelvic score decreased from 24.10 to 6.95 and the size of the fibroids decreased by 69% at the end of 6 months of treatment. In conclusion, our data suggest that the use of GnRH agonist has a place in the treatment of endometriosis and uterine leiomyoma but further studies are needed to conclude that buserelin given intranasally at a dose of 600 micrograms/day for 6 months is an alternative to other conventional medical treatment modalities in terms of pregnancy and recurrence rates.

A randomized and double-blind trial was carried out comparing intranasal nafarelin acetate (400 micrograms daily) and oral danazol (600 mg daily), given over 6 months, in the treatment of 49 patients with laparoscopically proven endometriosis. Both drugs produced a highly significant and similar reduction (of 60 to 70%) in objective American Fertility Society scoring, even in severe disease. No effect was seen on adhesions. Both drugs suppressed oestradiol levels to a similar extent, although nafarelin caused a substantial rise in the first 2 weeks after the initiation of therapy. Nafarelin suppressed LH substantially and FSH, testosterone and prolactin to a small degree, whereas FSH and LH increased slightly during danazol. Pregnancies occurred in 12 of 22 infertile women in the 12 months following nafarelin, and in 6 of 14 in the danazol group. Side-effects were reported at a similar rate with both drugs, but the pattern was different. Hot flushes were the predominant side effect with nafarelin, although oestradiol levels were not suppressed to the extent expected. Small amounts of spotting or light bleeding were experienced with both drugs, but these tended to decrease with time with nafarelin and increase with danazol.
