CYP2D6 genotype, antidepressant use, and tamoxifen metabolism during adjuvant breast cancer treatment. However, there are safer alternative antidepressants to take whilst on Tamoxifen that do not inhibit CYP2D6, such as escitalopram, venlafaxine and mirtazapine 52. If you are on tamoxifen and taking prescribed antidepressants, you will likely be taking one of these three options.

This enzyme converts the sex hormones androstenedione (produced by the ovaries), and testosterone, into oestrogen. Letrozole prevents this conversion by blocking the action of the aromatase enzyme. You can use a UK prescription to get medicines, including special food required for medical reasons, in Spain. The team are now working on a test to identify whether a patient’s tumour has started to increase aromatase production, and make its own estrogen. The team, whose findings are published in the journal Nature Genetics, hope their work will increase treatment options for patients whose cancer has returned. Combining hormone treatment with a targeted therapy such as palbociclib is one way of combating drug resistance – just as combination treatment is also used in diseases such as tuberculosis and HIV.

Growth of breast cancer is frequently stimulated by oestrogens which are female sex hormones. Letrozole reduces the amount of oestrogen by blocking an enzyme (“aromatase”) involved in the production of oestrogens and therefore may block the growth of breast cancer that needs oestrogens to grow. As a consequence tumour cells slow or stop growing and/or spreading to other parts of the body. “Patients with breast cancer often respond to various drug treatments, only for the cancer cells to adapt, change or sidestep the initial beneficial effects. • Neo-adjuvant treatment of postmenopausal women with hormone receptor positive, HER-2 negative breast cancer where chemotherapy is not suitable and immediate surgery not indicated.

At 24 months there was a statistically significant difference in the primary end-point; the lumbar spine BMD (L2-L4) showed a median decrease of 4.1% for letrozole compared to a median increase of 0.3% for tamoxifen. In healthy postmenopausal women, single doses of 0.1 mg, 0.5 mg, and 2.5 mg letrozole suppress serum oestrone and oestradiol by 75%, 78% and 78% from baseline respectively. There is no clinical experience to date on the use of Femara in combination with oestrogens or other anticancer agents, other than tamoxifen. Tamoxifen, other anti-oestrogens or oestrogen-containing therapies may diminish the pharmacological action of letrozole. In addition, co-administration of tamoxifen with letrozole has been shown to substantially decrease plasma concentrations of letrozole. Co-administration of letrozole with tamoxifen, other anti-oestrogens or oestrogens should be avoided.

The median time to crossover was 17 months (Femara to tamoxifen) and 13 months (tamoxifen to Femara). In the updated quality of life substudy there were no significant differences between treatments in physical component summary score or mental component summary score, or in any domain score in the SF-36 scale. The symptom that bothered most patients in both treatment arms was aching muscles, with a statistically significant difference in favour of placebo. In postmenopausal patients with advanced breast cancer, daily doses of 0.1 mg to 5 mg suppressed plasma concentration of oestradiol, oestrone, and oestrone sulphate by 75-95% from baseline in all patients treated. With doses of 0.5 mg and higher, many values of oestrone and oestrone sulphate were below the limit of detection in the assays, indicating that higher oestrogen suppression is achieved with these doses. Oestrogen suppression was maintained throughout treatment in all these patients.
