After approximately 2 weeks menstrual delay (positive Pregnosticon Tests) "menstrual induction" was attempted in 75 gravidas by repeated vaginal application of a gel, containing 200 or 400 mug/ml ICI 81008. After approximately 10 minutes, following the 1st vaginal delivery of 400 mug ICI 81008, the uterus responded to this PGF2alpha analogue with sustained contracture. The highest success rate in induced bleeding (93%) and pregnancy termination (79%), without supportive therapy, was achieved when 400 mug ICI 81008 was administered 2 to 5 times at 4 hour intervals. Those gravidas (21%), who failed in induced menstruation, or stopped bleeding within 24 hour- after treatment, had positive Pregnosticon Tests on day 14 and were curetted. The side effects, mostly vomiting and increased blood pressure, were transient and subjectively and medically acceptable. While the vaginal application of the drug is apparently less effective than the intrauterine (1), it has the advantage of simple delivery and the potential of self-administration.

Emetic and antiemetic properties of opioid peptides, substance "P", beta-lipotropin, and ACTH1-39 have been investigated in experiments on cats. It was shown that morphine, enkephalin, beta-endorphin and DADLE caused vomiting in animals, which was blocked by naloxone. Substance "P", gamma- and des-tyr-gamma-endorphin manifested antiemetic properties similar to those of naloxone. Selective antagonists of delta-opioid receptors ICI 154, 129 blocked emetic action of delta-agonist DADLE but did not prevent vomiting caused by mu-agonist morphine. It is suggested that the vomiting mechanisms of endogenous opioid peptides involve stimulation of mu- and delta-opioid receptors in the chemoreceptor trigger zone of the vomiting centre.

Patients with hormone-sensitive breast cancer who have responded to tamoxifen may receive additional benefit from a second endocrine agent following progression or relapse after tamoxifen therapy. Fulvestrant (Faslodex((R)), ICI 182780, AstraZeneca Pharmaceuticals; Wilmington, Delaware) is a selective antagonist of estrogen designed to have no estrogenic effects. Lack of aqueous solubility led to the development of a parenteral formulation for monthly intramuscular administration. Fulvestrant has been shown to inhibit the proliferative effects of estrogen on sensitive tissues in vitro and in vivo, and is without apparent measurable estrogenic activity. The data upon which marketing approval for fulvestrant was based are summarized below. Eight hundred fifty-one postmenopausal women with advanced breast cancer were enrolled in two phase III studies, 400 in a North American double-blind study and 451 in a European open-label study, comparing the efficacy and safety of fulvestrant with anastrozole. Four hundred twenty-eight patients were randomized to receive fulvestrant 250 mg monthly by intramuscular injection and 423 patients were to receive anastrozole 1 mg daily. Patients were considered hormone sensitive either by receptor status or previous response to endocrine therapy. Over 96% of patients had previously received tamoxifen, either in the adjuvant setting or as treatment for metastatic disease. The primary study end points were response rate and time to progression. Response rates for patients treated with fulvestrant were 17% and 20% in the North American and European trials, respectively, compared with 17% and 15% in the anastrozole treatment arms. There were no statistically significant differences in response rates, time to progression, or survival between treatment arms in either study. The most common adverse events attributed to the treatment (>10%) were injection-site reactions and hot flashes. Common events (1%-10%) included asthenia, headache, and gastrointestinal disturbances (nausea, vomiting, and diarrhea), as well as rash and urinary tract infections. A small increase in joint disorders was reported in the anastrozole-treated patients. On April 25, 2002, fulvestrant 250 mg by monthly intramuscular injection was approved by the U.S. Food and Drug Administration for the treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women with disease progression following antiestrogen therapy. Approval was based on similarity of response rates and time to progression between fulvestrant and anastrozole.
