Classification
Pharmaceutical Tamoxifen/Nolvadex 20mg x 30 contains tamoxifen, a selective oestrogen receptor modulator (SERM). In the UK, tamoxifen is a prescription-only medicine used principally in the treatment of breast cancer. It is also licensed for certain cases of anovulatory infertility and primary prevention of breast cancer in women at moderate or high risk.
The stated 20mg x 30 indicates 20mg of tamoxifen per tablet and a pack quantity of 30 tablets.
What is Pharmaceutical Tamoxifen/Nolvadex 20mg x 30?
Pharmaceutical Tamoxifen/Nolvadex 20mg x 30 is an oral tablet containing 20mg of tamoxifen. Nolvadex is a recognised brand name for tamoxifen.
Tamoxifen works by interacting with oestrogen receptors and is particularly important in the management of certain oestrogen-receptor-positive breast cancers. The exact formulation, manufacturer and regulatory status should always be checked for a particular product.
Important product information includes:
- Active ingredient and strength
- Manufacturer details
- Batch or lot number
- Expiry date
- Packaging integrity
- Prescription information
- Applicable UK regulatory status
Dosage
For the treatment of breast cancer, UK product information states that the usual adult dose is 20mg daily. Higher doses have not demonstrated additional benefit for delayed recurrence or improved survival.
The appropriate dosage depends on the medical indication and individual circumstances. Tamoxifen should therefore be taken only according to a prescriber’s instructions.
How Does Pharmaceutical Tamoxifen/Nolvadex 20mg x 30 Work?
Tamoxifen acts primarily by binding to oestrogen receptors. In breast tissue, it can block the effects of oestrogen, which can reduce oestrogen-driven stimulation of susceptible breast cancer cells.
Its activity can vary between different tissues, which explains why tamoxifen has both anti-oestrogenic and oestrogen-like effects in different parts of the body.
Benefits
When appropriately prescribed, tamoxifen provides established therapeutic benefits in specific medical circumstances.
Potential benefits include:
- Supporting treatment of certain breast cancers
- Reducing the risk of recurrence in appropriate patients
- Providing a treatment option for hormone-sensitive breast cancer
- Supporting primary breast cancer risk reduction in eligible women
- Supporting treatment of certain cases of anovulatory infertility
Treatment benefits depend on the patient’s diagnosis, hormonal receptor status and overall clinical circumstances.
When Should You Not Take Pharmaceutical Tamoxifen/Nolvadex 20mg x 30?
Tamoxifen is not appropriate for everyone. It is contraindicated during pregnancy and in people with known hypersensitivity to tamoxifen or its ingredients. It should also not be used concurrently with anastrozole.
Additional restrictions depend on the indication. For example, tamoxifen used for primary breast cancer prevention should not be used in women with a history of deep-vein thrombosis or pulmonary embolism, or those requiring coumarin-type anticoagulants.
What is the Mechanism of Pharmaceutical Tamoxifen/Nolvadex 20mg x 30?
Tamoxifen is a selective oestrogen receptor modulator. It binds to oestrogen receptors and alters oestrogen signalling in a tissue-dependent manner.
In breast tissue, its anti-oestrogenic activity can inhibit oestrogen-mediated stimulation of tumour cells. This pharmacological action forms the basis of its use in hormone-sensitive breast cancer.
Uses of Pharmaceutical Tamoxifen/Nolvadex 20mg x 30
UK-authorised tamoxifen products have several established indications, depending on the specific product and clinical circumstances.
These include:
- Treatment of breast cancer
- Treatment of certain cases of anovulatory infertility
