    Tamoxifen interactions


    Generic drugs usually cost less than a brand-name drug. Tamoxifen oral tablet is only available as a generic drug. Tamoxifen is used to treat and reduce the risk of certain types of breast cancer. Tamoxifen belongs to a group of drugs called antiestrogens. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions. Antiestrogens work by blocking the effects of the hormone estrogen in the body. There are several Tamoxifen drug interactions that people taking this medication should be on the lookout for. The best way to prevent any interaction, whether it is mild or severe, is for patients to disclose any over-the-counter or prescription medications they are taking with their physicians and their pharmacists. There are a few mild and moderate drug interactions associated with Tamoxifen, though most of these are linked to taking products that contain estrogen or other synthetic hormones. This is because Tamoxifen is designed to block the natural hormones already being produced within the body in an effort to slow the growth of certain types of cancers. Patients should also avoid consuming soybeans and alcohol during their course of treatment with this medication. Since the purpose of Tamoxifen is to block the production of certain hormones in the body, the lack of these hormones may cause the active ingredients of other medications to become too concentrated, or not concentrated enough, within the bloodstream. Patients should always check the labels of any over-the-counter and prescription medicines they take for the ingredients listed below: There are many medications available over-the-counter and by prescription that contain the active ingredient diphenhydramine.

    Several of us have posted in recent months about the importance of using care in selecting an antidepressant, because certain ones can reduce the effectiveness of tamoxifen. I just came across an artricle in Worst Pills, Best Pills News (March 2009) which warns that a numder of other medications can also block the effectiveness of tamoxifen. I will paste some excerpts from the article below: Watch Out For Interactions with Tamoxifen (Nolvadex) Breast cancer is the most common cancer in women and tamoxifen (NOLVADEX ) is used commonly in the treatment and sometimes in the prevention of this disease. In 2007, 1.7 million prescriptions were filled for tamoxifen. However, recent evidence suggests that certain other drugs can reduce the anti-cancer effects of tamoxifen, potentially increasing cancer recurrence and reducing survival. Certain antidepressants, such as fluoxetine (PROZAC), paroxetine (PAXIL) and bupropion (WELLBUTRIN), could reduce the effect of tamoxifen because they are among the most potent CYP2D6 inhibitors. Tamoxifen is a "prodrug," which means that the drug molecules in the medication itself are inactive; they must be transformed by the body to the active molecules that actually produce the beneficial effects. Some people may have a genetic CYP2D6 deficiency that may interfere with the effectiveness of tamoxifen. What drugs may reduce the effect of' tamoxifen? Тамоксифен является нестероидным антиэстрогенным средством, обладающим также слабыми эстрогенными свойствами. Его действие основано на способности блокировать рецепторы эстрогенов. В противоположность рецепторному комплексу эстрогена рецепторный комплекс тамоксифена не стимулирует синтез ДНК в ядре, а угнетает деление клетки, что приводит к регрессии опухолевых клеток и их гибели. Максимальная концентрация в сыворотке достигается в пределах от 4 до 7 часов после приема однократной дозы. Равновесная концентрация тамоксифена в сыворотке крови обычно достигается после 3-4 недельного приема. Метаболизируется в печени с образованием нескольких метаболитов. Выведение тамоксифена из организма имеет двухфазный характер с начальным периодом полувыведения от 7 до 14 часов и с последующим медленным терминальным периодом полувыведения в течение 7 дней. Выделяется главным образом в виде конъюгатов, в основном, с каловыми массами и лишь небольшие его количества выделяются с мочой.

    Doxycycline is a semi-synthetic tetracycline antibiotic prescribed to treat various bacterial infections such as urinary tract and bladder infections. Veterinarians also use Doxycycline to treat some diseases such as Rocky Mountain Spotted Fever and Lyme disease. Veterinarians prescribe Doxycycline because it’s a strong, effective antibiotic with extended effectiveness against some diseases. Your dog may take Doxycycline to treat a short-term bacterial infection such as a urinary tract or bladder infection. Or your pet's veterinarian may recommend Doxycycline to treat a longer-term disease such as Rocky Mountain Spotted Fever, Lyme Disease, Ehrlichiosis, or chlamydia. This medication prevents bacteria from reproducing so the animal’s immune system can fight the existing infection. Talk to your pet's veterinarian about the proper way to dose Doxycycline to avoid potential side effects.
