A phase I study (open trial) of bicalutamide (Casodex), a non-steroidal antiandrogen, was conducted on 16 patients with prostatic cancer (stage C to D). The patients were given 10, 30, 50, 80 or 100 mg of bicalutamide orally daily for 12 weeks. Adverse reactions were observed in 8 out of 16 patients, but almost all were mild. Breast pain, gynecomastia and hot flushes were observed in 6 patients. Adverse reactions regarding liver function tests were observed in 3 patients. These were increased glutamic-oxalacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), alkaliphosphatase (AL-P) or gamma guanosine 5'-triphosphate (gamma-GTP). However, during or after the treatment period the elevated values were reversed to the pretreatment level. In terms of efficacy, anti-tumor effect was observed in 1 or 2 patients at each dose. Serum concentrations of luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone and estradiol increased during treatment. Plasma concentrations of the R (-) enantiomer, which has antiandrogenic activity, reached the steady state 6-8 weeks after the initiation of treatment; its apparent plasma elimination half-life observed following repeated administration was 8.4 +/- 1.1 days. In conclusion, bicalutamide (10-100 mg od) is considered to be tolerated well enough to be administered to patients with prostatic cancer and has shown evidence of anti-tumor effect.

This 12-week, double-masked, double-dummy, randomized, parallel-group study compared the efficacy and safety of an estradiol matrix transdermal delivery system (Alora) in two strengths (50-microgram/d estradiol and 100-microgram/d estradiol) with placebo in postmenopausal women who were experiencing at least 60 moderate-to-severe hot flushes per week. In 273 postmenopausal women, the reduction in the frequency of moderate-to-severe hot flushes was significantly better than placebo within 2 weeks of initiating therapy in the 100-microgram/d group and within 3 weeks of initiating therapy in the 50-microgram/d group. The reduction in hot flushes for both active treatment groups remained significantly different from placebo throughout the 12-week trial. Improvement in vaginal cytology profile (maturation index) was observed in both active treatment groups. Serum estradiol concentrations were elevated to early-to mid-follicular levels, in proportion to dose, and the estradiol/estrone ratio remained within the expected premenopausal range. The incidence of estrogen-related side effects was modest but greater in the active treatment groups than in the placebo group: Breast pain was reported in 4.5% of the patients in the 50-microgram/d group, 5.3% of patients in the 100-microgram/d group, and none of the patients in the placebo group. Breakthrough bleeding occurred in 3.4% of women in the 50-microgram/d group, 20.2% of women in the 100-microgram/d group, and 4.4% of women in the placebo group. Only 3 (1.1%) patients terminated treatment because of skin reactions. This study demonstrates that this estradiol matrix transdermal delivery system is effective in the treatment of menopausal symptoms, while providing the skin tolerability desired by patients.

This double-blind, randomized, multi-center study compared the efficacy and clinical tolerance of a combined formulation containing 2 mg estradiol (E2) and 0.5 mg trimegestone (TMG) with a standard hormone replacement therapy containing estradiol valerate (E2V) and norgestrel (NG) in the treatment of climacteric symptoms. The study was conducted over 13 cycles, each of 28 days, and involved 634 subjects, of whom 481 completed the study. The primary efficacy variable was the percentage of subjects who showed at least a 50% reduction from baseline in the mean daily number of hot flushes in cycle 3. This was observed in 98.5% of the subjects in the E2 + TMG group and 93.3% of the subjects in the E2V + NG group (95% confidence interval of the difference, -8.6, -1.9). Significant differences in favor of the E2 + TMG combination were observed in the reduction in the mean daily number and severity of hot flushes, and in the percentage of subjects who had hot flushes at baseline but no hot flushes during treatment. There were no significant differences between the treatments in the Kupperman index and in urogenital signs or symptoms. Treatment with the E2 + TMG combination was well tolerated and the incidences of adverse events were similar in the two treatment groups. Breast pain was the main adverse event, possibly related to treatment that resulted in discontinuation. The mean number of bleeding days per cycle was significantly lower with the E2 + TMG combination than with the E2V + NG combination. The incidences of endometrial hyperplasia were low and comparable in both treatment groups. It was concluded that the E2 + TMG combination was either equivalent or superior to the E2V + NG combination in the treatment of hot flushes and other climacteric symptoms, and that its bleeding profile was favorable.

Aim of the present work was to investigate the clinical efficacy of Kuntai capsule in the treatment of postmenopausal women with endometriosis, Breast pain and Vaginal Bleeding. 120 elderly female outpatients over 50 years old with Breast pain were randomly divided into control group (60 cases) and observation group (60 cases). All patients were given diclofenac sodium enteric-coated tablets 25mg, 3 times a day. The observation group was given additional Kuntai capsules at a dose of 4 capsules per time, 3 times a day. Serum estradiol (E2), follicle stimulating hormone (FSH), and luteinizing hormone (LH) were detected in all patients before and at 12 weeks after treatment. Modified Kupperman score (K score) for evaluating menopausal symptoms. The post therapeutic serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) level and endometrial thickness decreased significantly (p<0.05). After treatment, KMI scores of kunati group was significantly decreased compared with baseline (<0.01) and there was no significant difference between groups (p>0.05). After treatment, hot flush and insomnia scores were both improved significantly. After therapy, serum E2 level obviously higher than the control groups, while FSH and LH levels were obviously lower (p<0.05). The incidence of vaginal bleeding, breast distending pain in group was obviously higher in control group than Kuntai group. Thus, Kuntai capsule improved the ovarian function of patients, raised the level of estrogen in vivo and alleviates the clinical manifestations of Breast pain.
