Did You Know? Tamoxifen is a selective estrogen receptor modulator (SERM) that is used to treat and prevent breast cancer. It is indeed one of the most widely prescribed hormone therapies for breast cancer patients.
Why Dissolution Tests Matter
Dissolution tests are standard procedures conducted by regulators and manufacturers to ensure that a medication’s active ingredient is released into the body at the expected rate. These tests are vital for predicting how the drug will perform once consumed. The effectiveness of oral medications like Tamoxifen depends on proper dissolution in the gastrointestinal tract before absorption into the bloodstream.
When tablets fail these tests, it can indicate potential problems with how the drug will work in patients. Wockhardt UK Limited initiated the recall as a precautionary measure after identifying the dissolution failure during routine stability testing. The affected batch was first distributed on August 22, 2024.
Tamoxifen’s Role in Breast Cancer Treatment
Tamoxifen is a vital medication for approximately 550,000 British breast cancer survivors, capable of reducing their risk of disease recurrence by up to 45 percent. The drug functions by blocking estrogen activity in the body, preventing it from reaching cancer cells and slowing or stopping tumor growth [[3]].
Originally developed as a contraceptive in 1962, Tamoxifen transformed breast cancer treatment in the 1980s when trials demonstrated its effectiveness post-surgery. The national Institute for Health and Care Excellence now recommends it for roughly 80 percent of breast cancer patients. In 2013, it became the first drug prescribed to prevent cancer, offered to women with strong family histories of the disease.
pro Tip: Always consult with your healthcare provider or pharmacist if you have any concerns about your medications.
Guidance for Healthcare Professionals and Patients
The MHRA has instructed healthcare professionals to promptly stop supplying the affected batch and quarantine all remaining stock for return to suppliers. Pharmacists and dispensing GPs have been notified through NHS regional teams.
Patients are advised to continue taking their medication as prescribed, with the recall being managed at the pharmacy and wholesaler levels as a precautionary measure.Anyone experiencing adverse reactions should seek medical attention promptly. The MHRA encourages reporting of any suspected adverse reactions through its Yellow Card scheme, established in the 1960s to monitor drug safety.
