The 5 most effective anti-aromatase substances

Dietary fibre is one contributor, with an increase fibre intake of up to 30g demonstrating significant reductions in oestrogen, versus those not consuming fibre in their diet. Liver diseases are also known to contribute to elevated oestrogen as there is a high level of aromatase present in the liver too. Perhaps due to the potent antioxidant effects of oestrogen; if the liver is damaged, then an increase in oestrogen should help protect it 10,11.

Neoadjuvant trials with antihormone therapy have generally shown that the chance of breast conservation is higher with AIs than tamoxifen and may be higher for AIs than for chemotherapy in women with hormone receptor positive tumours (19–22). In a trial comparing neoadjuvant letrozole with tamoxifen, the mammographic complete response rate with letrozole, although very low, was still higher than that observed for tamoxifen (20). Neoadjuvant antihormonal therapy with an AI is a particularly attractive option for postmenopausal women who wish to attempt breast conservation and Steroids have strongly ER- and PgR-positive tumours that are ≥ 3 cm and have low proliferation rates. For women with newly diagnosed hormone receptor positive ER+ cancers requiring systemic adjuvant therapy, 5 years of tamoxifen reduces the relative odds of recurrence by 40% and relative risk of death from breast cancer by 34% (10). At 15 years this equates to about a 12% absolute reduction in recurrence and a 9% absolute reduction in mortality, irrespective of nodal status. However, about a third of women diagnosed with ER-positive breast cancer will ultimately relapse despite adjuvant tamoxifen with or without chemotherapy (10).

Enhancing Healthcare Team Outcomes

There are quite a few pharmaceutical aromatase inhibitors on the market, namely Arimidex (anastrozole), Aromasin (exemestane), Nolvadex (tamoxifen), and Femara (letrozole). These drugs are non-steroidal compounds that strongly blunt the aromatization of androgens. They can drastically reduce estrogen levels in a short amount of time, so you should only use them under medical supervision. In randomised studies, arthralgias/myalgias have been reported significantly more frequently in women randomised to AIs than in those randomised to tamoxifen or placebo. The absolute frequency varies tremendously from trial to trial (5.4–37% for AIs vs. 3.6–26% for tamoxifen or placebo), which in turn probably reflects the method used to record the symptoms. The incidence of arthralgias and myalgias appear to be about two-thirds higher with an AI than with tamoxifen or placebo but usually improves with time (38).

  • In addition, given the different effect of androgens and estradiol on RORA expression, it would be interesting to determine whether this molecule is involved in sex differences in ASDs, which affect predominantly males.
  • The primary outcome measure was insulin sensitivity as assessed by glucose disposal during a hyperinsulinemic-euglycemic clamp (14).
  • Aromatase is responsible for converting androgens (male hormones) into estrogens (female hormones).
  • By closely monitoring these parameters, healthcare providers can tailor treatments to individual needs, optimize the effectiveness of therapy, and minimize adverse effects.
  • Nevertheless, our results have clinical implications that may impact the treatment of men with hypogonadism.

Adjuvant Therapy

Previous studies using AI in men were short term, did not evaluate glucose homeostasis comprehensively, included a mixed population of diabetic and non-diabetic men, and did not include comparison groups given transdermal testosterone and placebo. Hence, we performed this proof-of-concept mechanistic trial of 12 months duration to determine the effects of long-term treatment with AI on glucose homeostasis and cardiovascular risk markers in nondiabetic elderly men. Anastrozole is a medication used in the management and treatment of breast cancer. This activity describes the indications, action, and contraindications for anastrozole as a valuable agent in managing advanced hormone-receptive breast cancer. AI have been used in boys with ISS and CDP to increase adult height.1,4,5 Boys with ISS with a mean age of 11 years were treated with letrozole 2.5 mg once daily or placebo for 2 years. There was marked improvement in SMR in case A with “sole” therapy with letrozole, but insignificant response in gynecomastia.

These can range from changing lifestyle factors (such as sleep and diet) to medications. Changes to the ratio of estrogen and testosterone (testosterone declines annually by 1% per year, and the ratio to estrogen will therefore decrease) in the body can result in health problems for some people. For vasomotor symptoms, non-hormonal methods such as selective serotonin reuptake inhibitors (SSRIs), gabapentin or clonidine should be tried first (63). In doses commonly needed for relief of hot flushes (75 mg venlafaxine, 20 mg fluoxetine and 300–900 mg gabapentin), side effects for these medications include drowsiness, dry mouth and dyspepsia.

In contrast to premenopausal women, in whom most of the estrogen is produced in the ovaries, in postmenopausal women estrogen is mainly produced in peripheral tissues of the body. The heightened gonadotropin levels also upregulate the aromatase promoter, increasing aromatase production in the setting of increased androgen substrate. This would counteract the effect of the aromatase inhibitor in premenopausal women, as total estrogen would increase. In the Testis, the Leydig, Sertoli, and Germ cells are abundant in aromatase and oestrogen, where oestrogens serve to modulate testosterone production and sperm production and quality 1. Furthermore, the penile vasculature and the urothelium of the penis are lined with oestrogen receptors, where oestradiol modulates erectile function in the penis. This extends further to the cardiovascular system too, with oestrogen receptors within it that provide several protective effects on your cardiovascular system.

So if you are afraid of anti estrogens switch to aromasin but most of all. Just stop being weird and take care of yourself if you’re having problems.
