The effects of TAM can be demonstrated in ways other than targeting cancer Abstract
It is widely used for treatment of breast cancer; however, analogous with many antineoplastic agents, tamoxifen is associated Purpose: To describe a case of tamoxifen toxicity superimposed on central serous chorioretinopathy (CSCR)
It is also being studied for other types of cancer
The breast cancer medication most commonly identified with ocular side effects is tamoxifen
Long term tamoxifen therapy has been associated with development of fatty liver, steatohepatitis, cirrhosis, and rare instances of clinically apparent acute liver injury
Multimodal image studies were used to evaluate three female patients who were receiving Tamoxifen is an anti-oestrogenic drug widely used for adjuvant therapy of breast cancer
Tamoxifen (TAM; a selective estrogen receptor modulator), which has so far been used mainly as an adjuvant therapeutic in breast cancer, in recent preclinical studies has shown the potential to alleviate ovarian side effects of cancer treatment [8-10]
Tamoxifen is a selective estrogen receptor (ER) modulator that acts as an anti-estrogen
A full ophthalmic evaluation was done every 6 months, for a median of 30 months (range 4-79 months)
However, when tamoxifen was injected IP (75 mg/kg) for 3 consecutive days from postnatal day 9 (P9) to P11, we observed Tamoxifen / adverse effects
The findings have been previously compared to macular Purpose: The oral antiestrogen tamoxifen has demonstrated efficacy in the treatment of metastatic breast cancer and as adjuvant therapy in early-stage disease
However, because tamoxifen is known to form drug-lipid complexes inhibiting normal catabolism of lipids in the lysosomes, 7
Materials & methods: TAM-SFN-NLCs were prepared using Precirol ® ATO5 and Transcutol ® HP, characterized and evaluated in vitro and ex vivo to assess the drug release profile and intestinal permeability, respectively

Monotherapy: 20 mg twice daily until disease progression or unacceptable toxicity (Thigpen 2001)
Based on the case reports and studies performed to date on the retinal toxicity of tamoxifen, retinopathy appears to occur in as many as 12% of patients taking 20 mg tamoxifen a day for over 2 years
Tamoxifen is used alone or as an adjuvant in these treatments
Methotrexate injected intratracheally can cause optic neuropathy and ophthalmoplegia
1995 Mar;43 (1):23-6
A number of ocular complications have been described secondary to tamoxifen therapy
1 years in 500 patients, there were 14 neoplastic events with tamoxifen and 28 with placebo (HR 0
Clinical studies indicate that exposure even to tamoxifen (TMX), a putatively benign antihormonal agent widely used in breast cancer treatment, causes cognitive dysfunction and changes in CNS metabolism, hippocampal volume, and brain structure
2 Long-term tamoxifen has generally only few and usually mild adverse side effects
Had tamoxifen been tested for carcinogenicity 30 years Implications for practice: This secondary analysis of a prospective CYP2D6 genotype-guided tamoxifen dose escalation study confirms that escalation to 40 mg/day in patients with low-activity CYP2D6 phenotypes (poor or intermediate metabolizers) increases endoxifen concentrations without any obvious increases in treatment-related toxicity
There was a wide range for the time Screening for ocular toxicity in asymptomatic patients treated with tamoxifen
Conclusion This review has collated substantial randomised controlled trial and observational evidence on the effect of endocrine therapies on several specific cardiovascular disease outcomes including venous thromboembolism and myocardial infarction, progressing knowledge
With the continued popularit of tamoxifeny , This indicates that tamoxifen toxicity relies on two distinct mechanisms depending on the dose: at low doses, tamoxifen slows the growth of ER-positive, but not ER-negative cells, whereas, at high Indeed, tamoxifen has been shown to have favorable effects on serum lipid levels, with decreases of up to 39 mg/dL for total cholesterol and 31 mg/dL for low-density lipoprotein cholesterol from baseline to 3 months of follow-up; this effect was shown to persist up to 1 year after treatment initiation
Although medicines are less toxic than other toxicants, increased production and usage of pharmaceuticals have led to many concerns regarding their toxic effects on human and non-target organisms
Tamoxifen normalizes the expression level of the XLMTM disease modifiers DNM2 and PI3KC2B, likely contributing to the phenotypic rescue
Tamoxifen can cause retinal damage through multiple mechanisms, but the two most studied are related to direct toxicity to retinal cells and their off-target effects on Müller glia
Prevention trials with selective estrogen receptor modulators (SERMs), such as tamoxifen, demonstrate a reduction in overall breast cancer incidence of 38% with a reduction of 51% for estrogen receptor (ER)-positive invasive disease alone []
In this review we focus on the role of Tamoxifen in breast cancer treatment including
Tamoxifen reduces the risk of recurrence and death from breast cancer when given as adjuvant therapy and provides effective palliation for patients with metastatic

Tamoxifen is an estrogen modulator that acts to competitively inhibit the binding of endogenous estrogens

To look at the incidence, symptomatology, course and reversibility of low-dose tamoxifen ocular toxicity
Novel high potency, third-generation Tamoxifen can cause retinal damage through multiple mechanisms, but the two most studied are related to direct toxicity to retinal cells and their off-target effects on Müller glia
Tamoxifen is a non-steroidal antiestrogen used to treat estrogen receptor positive breast cancers as well as prevent the incidence of breast cancer in high risk populations
Tamoxifen toxicity occurs by oral and intraperitoneal administration, in both sexes, in multiple strains, and does not depend on estrogen, though acid secretion inhibition is partially protective

By reviewing the recent articles regarding the ocular side effect of tamoxifen when treating breast cancer and glioma, this article summarized the incidence and the potential mechanism of the side effects of tamoxifen, and the specific ocular toxicity
