Thousands of women offered anastrozole to help prevent breast cancer Cancer Research UK

Incidence of 25-OH vitamin D deficiency in patients with a history of breast cancer who have musculoskeletal symptomatology. The same study mentioned by Dr Irwin above, known as the HOPE study (Hormones and Physical Exercise) [10], found that more intense strength based training helped to reduce the eventual pain scores even further. There are many resources where these types of exercises can be found, please have a look at this BreastCancer.org page. It was first recommended as a preventive option by the National Institute for Health and Care Excellence in 2017, however, with the treatment being unlicensed in this use, uptake has remained low. If you’re taking any other prescribed or over-the-counter medicines, check with your treatment team or pharmacist if you can take these with anastrozole.

• In postmenopausal women, estradiol is produced primarily from the conversion of androstenedione to estrone through the aromatase enzyme complex in peripheral tissues.
• For example, a recent study found that patients previously treated with tamoxifen experienced greater pain when they switched to AIs and had an excess risk of stopping the therapy the first 12 months [8].
• The Medicines Repurposing Programme will work with the MHRA and the British Generic Manufacturers Association to establish that other companies which supply the treatment adopt its new licensed indication.
• Trial 0001 was an open-label, multiple-dose pharmacokinetic study of Arimidex 1 mg/day in 36 pubertal boys with gynaecomastia of less than 12 months duration.

Talk to your doctor or nurse about effective contraception you can use during treatment. Ask how long you should use it before starting treatment and after treatment has finished. Various things can help you to reduce tiredness and cope with it,for example exercise. Some research has shown that taking gentle exercise can give you more energy. Remember it is very unlikely that you will have all of these side effects, but you might have some of them at the same time. There is no evidence that drinking alcohol causes any problems when taking anastrozole.

Side effects of anastrozole (Arimidex)

Compound 11 was modelled into the active site of a homology model of human aromatase and the X-ray crystal structure of steroid sulfatase. Ground-breaking research has found that the drug, anastrozole, continues to reduce the risk of breast cancer, even 10 years after initial treatment. However, no data exist on the cytochromes involved in Anastrozole hepatic detoxification. Today’s announcement confirms the authorisation for prevention in post-menopausal women at moderate or high risk of developing the disease. In a large phase III study conducted in 9,366 postmenopausal women with operable breast cancer treated for 5 years (see below), Arimidex was shown to be statistically superior to tamoxifen in disease-free survival.

• If your symptoms are temporary and not too intense, then you could consider using these pain relief medications.
• Women with a higher risk of developing breast cancer are set to be offered a pill that cuts their risk of developing the disease in half.
• Certain medicines should not be used during pregnancy or breastfeeding.
• NHS England is working with a pharmaceutical company, Accord, and the Medicines and Healthcare products Regulatory Agency (MHRA) to get an independent assessment of using the drug for preventative purposes.
• To learn more about what we are looking for and to propose a potential candidate, please view the interim eligibility criteria and candidate proposal form.
• The following table presents adverse reactions from clinical trials, post-marketing studies or spontaneous reports.

It’s vital that we keep advocating for new preventative treatments to bring these numbers down and help thousands of women every year avoid hearing the shattering news that they have breast cancer. As with most medicines there may be common side effects, which include hot flushes, feeling weak, pain/stiffness in the joints, arthritis, skin rash, nausea, headache, osteoporosis, and depression. Most women diagnosed with breast cancer are over the age of 50, but younger women can also get breast cancer. Around 1 in 7 women will be diagnosed with breast cancer in their lifetime. Every year, around 56,000 women in the UK are diagnosed with breast cancer – about 150 a day.

How can Arimidex affect other medicines?

This reduces the risk of breast cancer, as oestrogen fuels the growth of some versions of the disease. This aims to ensure that drugs which are licensed for one use – such as treatment – can get the green light for another, such as prevention if they are found to be effective. Under the new system, the Medicines and Healthcare products Regulatory Agency has licensed the new purpose, after pharmaceutical company Accord Healthcare agreed to apply for the licence on a not-for-profit basis.

• The first phase of this study, published in 2013, established its value as a prophylactic therapy.
• These effects were related to the pharmacological effects of the compound on parturition.
• Joint pain is one of the most common symptoms for those taking Aromatase Inhibitors (AIs), such as anastrozole, as their form of hormone treatment.

There are a number of other brands of anastrozole, all of which contain the same dose of the drug. It’s a worrying time for many people and we want to be there for you whenever – and wherever – you need us. Cancer Chat is our fully moderated forum where you can talk to others affected by cancer, share experiences, and get support. Speak to your healthcare team about painkillers to help with this.

How do I take Arimidex?

While not all of these would necessarily be fatal, it will save these women from having to treatments such as surgery or gruelling chemotherapy. However, Britain’sMedicines Repurposing Programme, which was set up in 2021 by the NHS, Government and UK drug and treatment watchdogs, takes on this process. The human body naturally converts excess testosterone into oestrogen. Anastrozole works by stopping “aromatase”, a chemical that the body uses as part of this process. As anastrozole can have a number of side effects, in the UK GnRH agonists are usually used to stop the production of oestrogen instead.

Those who have two such relatives getting breast cancer at any age could also be considered for the drug, as would those with a mix of first and second-degree relatives (such as an aunt, grandparent or niece). GPs will be asked to examine the medical histories of such patients and advise – sometimes with specialist involvement – on the estimated level of risk, and whether the drug is thought suitable. Around 300,000 women will be offered the medication anastrozole under plans to routinely prescribe drugs to prevent cancer. A daily pill that halves the risk of breast cancer is to be rolled out on the NHS in “a new era for cancer prevention”. But questions remain as to how this new treatment can be combined with a healthy lifestyle to lower the risk of developing the disease.

These changes are considered to be mouse-specific effects of aromatase inhibition and not clinically relevant to the treatment of patients with anastrozole. A two-year rat oncogenicity study resulted in an increase in incidence of hepatic neoplasms and uterine stromal polyps in females and thyroid adenomas in males at the high dose (25 mg/kg/day) only. These changes occurred at a dose which represents 100-fold greater exposure than occurs at human therapeutic doses, and are considered not to be clinically relevant to the treatment of patients with anastrozole. Oral administration of anastrozole to female rats produced a high incidence of infertility at 1 mg/kg/day and increased pre-implantation loss at 0.02 mg/kg/day. These effects were related to the pharmacology of the compound and were completely reversed after a 5-week compound withdrawal period.

The study was funded by Cancer Research UK, and the National Health and Medical Research Council, Australia, and the Royal Marsden Cancer Charity. Anastrozole (Arimidex) is accepted for restricted use within NHS Scotland in the adjuvant treatment of postmenopausal women with hormone receptor-positive early invasive breast cancer. Anastrozole has shown benefit over standard anti-oestrogen therapy in terms of disease-free survival in this patient group. It offers an alternative to tamoxifen and has a different adverse effects profile. Treatment with anastrozole should be initiated by a breast cancer specialist.
