#30: tamoxifen (Soltamox) | Reducing the Risk and Treating Breast Cancer

Tamoxifen is a selective estrogen receptor modulator that comes in both a tablet and solution. The tablet comes in a 10 mg and 20 mg strength and the solution comes in a 10 mg/5 mL concentration. Tamoxifen, also known as the brand name Femara, when used in reducing the risk of Breast Cancer in high risk females the dosing is 20 mg once daily for 5 years. When used in treating Breast Cancer the dosing does vary at 20-40 mg once daily. When 40 mg is needed per day the daily dose is divided into separate doses. When tamoxifen is metabolized via the CYP2D6 and CYP3A4/5 pathways the metabolites are 30-100 times more potent than tamoxifen itself. There is a black box warning for Uterine Malignancies and Thromboembolic Events. The monitoring parameters are bone mineral density, lipid panel, CBC with platelets, ophthalmic exam, and for medication adherence. The medication can be taken with or without food.  Go to DrugCardsDaily.com for my episode show notes which will contain a drug summary, quiz, and a link to FREE drug card sheets.
