Medical Definition of Aromatase inhibitor 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.

Anti-Nutrient: Enzyme Inhibitors Enzyme inhibitors are just that-molecules that inhibit the actions of enzymes. They are present in all seeds and prevent premature germination until environmental conditions are right for sprouting.Enzyme inhibitors are what allows us to store grains and seeds for long periods of time.nti-Nutrient: Enzyme Inhibitors. Enzyme inhibitors are another type of anti-nutrient. Before we get into enzyme inhibitors, let's talk about what enzymes are. Enzymes are catalysts for every chemical reaction in our body-from walking and talking to healing and digesting.

Enzyme inhibitor 1 In mixed inhibition, the inhibitor can bind to the enzyme at the same time as the enzyme's substrate. 2  However, the binding of the inhibitor affects the binding of the substrate, and vice versa. 3  This type of inhibition can be reduced, but not overcome by increasing concentrations of substrate.n enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors.

Breast cancer diet during aromatase inhibitor treatment There are some foods that can reduce these side effects while at the same time reducing the risk of a breast cancer recurrence. The following foods (or major bioactive components) have been found to inhibit aromatase or to enhance the effectiveness of aromatase inhibitors and are recommended during treatment:

Combo of Tykerb, Herceptin, and Aromatase Inhibitor Seems Best for Metastatic, HER2-Positive, Hormone-Receptor-Positive Disease A study has found that a combination of Tykerb (chemical name: lapatinib), Herceptin (chemical name: trastuzumab), and an aromatase inhibitor is better than just Herceptin and an aromatase inhibitor or just Tykerb and an aromatase inhibitor for treating metastatic HER2-positive, hormone-receptor-positive breast cancer in postmenopausal women.

Definitions &Translations Freebase(0.00 / 0 votes)Rate this definition: Aromatase, also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens. It is a member of the cytochrome P450 superfamily, which are monooxygenases that catalyze many reactions involved in steroidogenesis.

Acetylcholinesterase inhibitor Acetylcholinesterase inhibition. An acetylcholinesterase inhibitor (often abbreviated AChEI) or anti-cholinesterase is a chemical or a drug that inhibits the acetylcholinesterase enzyme from breaking down acetylcholine, thereby increasing both the level and duration of action of the neurotransmitter acetylcholine.ome major effects of cholinesterase inhibitors: 1  Actions on the parasympathetic nervous system, (the parasympathetic branch of the autonomic nervous system) may cause bradycardia, hypotension, hypersecretion, bronchoconstriction, GI tract hypermotility, and decrease intraocular pressure.

The Downside of Aromatase Inhibition Other estrogen-controlling drugs emerged, gaining favor due to their lower risk of side effects, low cost, and ease of use. During the 1990s, a new class of aromatase inhibitors, developed to aid in the fight against breast cancer, emerged onto the bodybuilding scene.

Aromatase Role in neuroprotection[edit] Aromatase in the brain is usually only expressed in neurons. However, following penetrative brain injury of both mice and zebra finches, it has been shown to be expressed in astrocytes. Furthermore, it has also been shown to decrease apoptosis following brain injury in zebra finches.

anastrozole Estrogen causes or increases growth of certain breast cancers. Anastrozole works by blocking aromatase enzyme, which is involved in estrogen production in the body. This leads to decreased tumor size or delayed progression of tumor growth in some women. The FDA approved brand name anastrozole (Arimidex) in 1995.
