In the US, codeine is a controlled substance that can only be administered by prescription. Actually your answer is not correct. Cough â¦syrup containing codeine can be purchased from a pharmacist and siging a log book. I am a Pharmacist and at least in Tennessee this is legal.
Aromatase inhibitor: A drug that inhibits the enzyme aromatase and by that means lowers the level of the estrogen estradiol. Aromatase inhibitors represent a class of antiestrogens. Aromatase catalyzes the conversion of testosterone (an androgen) to estradiol (an estrogen) in many tissues including the adrenal glands, ovaries, placenta, testicles, adipose (fat) tissue, and brain. Estrogen is produced directly by the ovaries and is also made by the body using aromatase. Aromatase inhibitors cannot do anything about estrogen produced by the ovaries, but they do interfere with the body's use of aromatase. The growth of many breast cancers is promoted by estrogens.
Aromatase inhibitors are only used to treat postmenopausal women. Premenopausal women should not take aromatase inhibitors. And, women with certain heart problems should not take the aromatase inhibitor anastrozole. Compared to chemotherapy, aromatase inhibitors have few side effects.For example, they do not cause nausea.p to 36 percent of women in clinical trials of aromatase inhibitors have reported joint pain and up to 15 percent have reported muscle pain (other studies have found even higher rates of these side effects) [ 73-75 ].
