toremifene and Pain

Breast pain may be cyclical (worse before a period) or non-cyclical, originating from the breast or the chest wall, and occurs at some time in 70% of women. Cyclical breast pain resolves spontaneously in 20% to 30% of women, but tends to recur in 60% of women. Non-cyclical pain responds poorly to treatment but tends to resolve spontaneously in half of women.. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for breast pain? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).. We found 24 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.. In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics, bromocriptine, combined oral contraceptive pill, danazol, diuretics, evening primrose oil, gestrinone, gonadorelin analogues, hormone replacement therapy (HRT), lisuride, low-fat diet, progestogens, pyridoxine, tamoxifen, tibolone, topical or oral non-steroidal anti-inflammatory drugs (NSAIDs), toremifene, and vitamin E.

Toremifen is effective in reducing breast pain and does not increase the incidence of adverse events as a therapy for moderate to severe mastalgia.. In a double-blind randomized controlled trial, patients with moderate to severe mastalgia received toremifen citrate, 30 mg daily, or a placebo tablet for 3 menstrual cycles and were followed up for breast pain score and adverse events. The serum levels of estradiol, progesterone, and prolactin were examined before treatment and correlated with the response rate to toremifen treatment.. Seventy-two (69.2%) of 104 patients receiving toremifen and 29 (31.9%) of 91 receiving placebo responded to the treatment, with reduction in breast pain score of more than 50% (P<.001). Among the patients with cyclical mastalgia, the response rate for toremifen was 76.7% (59/77), whereas the response rate for placebo was 34.8% (23/66; P<.001). In contrast, the response rate of patients with noncyclical mastalgia was 48.1% (13/27) for toremifen and 24.0% (6/25) for placebo (P = .09). Adverse events were observed in 44 (42.9%) of 104 patients receiving placebo and 46 (50.5%) of 91 patients receiving toremifen (P = .45). A positive correlation between baseline breast pain score and serum estradiol level was observed in patients with cyclical mastalgia (r = 0.35, P = .003).. Toremifen effectively relieves moderate and severe cyclical mastalgia and tends to exert a positive therapeutic effect on noncyclical mastalgia. In addition, toremifen therapy does not increase the incidence of intolerable adverse event. Therefore, it is a feasible therapy for mastalgia, especially cyclical mastalgia.

To investigate the efficacy of toremifene in the treatment of premenstrual mastalgia.. Double-blind, placebo-controlled crossover study.. Three Finnish general practices from the districts of Satakunta Central Hospital and Tampere University Hospital. POPULATION A total of 62 women aged 25-45 years with premenstrual mastalgia during at least three previous menstrual cycles.. Women were randomised to receive toremifene 20 mg daily or placebo from day 15 of the menstrual cycle until menstruation for three consecutive cycles. After a wash-out cycle, the women were crossed over to receive placebo or toremifene for three additional cycles.. Cyclic breast pain relief assessed by visual analogue scale (VAS) score. Quality-of-life scores assessed by a modified 36-item Finnish Depression Scale, with a score ranging from 0 to 108. Acceptability of treatment.. About 32 women were randomised to receive toremifene first and 30 to receive placebo first. Twenty-nine and 27 participants in the groups treated with toremifene first or placebo first completed the treatment, respectively. There were significant reductions in VAS scores in both groups after three treatment cycles. This was significantly greater in the toremifene-treated group (VAS: 1.8 in the toremifene group and 3.7 in the placebo group, P= 0.004). Treatment effect between treatment cycles was significant (P= 0.001). Quality of life was similar during the toremifene and placebo cycles. CONCLUSION This study demonstrates that the antiestrogenic compound, toremifene, is able to relieve premenstrual breast pain without major adverse effects. There was a 64% reduction in median pain scores in the toremifene-treated cycles compared with a 26% reduction in placebo-treated cycles.
