Investigated for use/treatment in postmenopausal osteoporosis to reduce the risk of both vertebral and novertebral fractures, as well as address other postmenopausal conditions, including reduction in risk of breast cancer and treatment of vulvar and vaginal atrophy (VVA)
Fablyn is indicated for the treatment of osteoporosis in postmenopausal women at increased risk of fracture. A significant reduction in the incidence of vertebral and non-vertebral fractures but not hip fractures has been demonstrated (see section 5. 1).
When determining the choice of Fablyn or other therapies, including oestrogens, for a postmenopausal woman, consideration should be given to menopausal symptoms, effects on uterine and breast tissues, and cardiovascular risks and benefits (see section 5. 1).
Lasofoxifene exhibits both significant estrogenic and antiestrogenic activity both in vitro and in vivo, targeting any tissues that possess ERs, such as bone, uterus, breast, blood vessels, and liver. Binding assays demonstrated high affinity of the compound for both ER and ER in a tissue-dependent manner. It mimics the effects of estradiol with varying agonist and antagonist effects.

Absorption
Peak plasma concentrations (Cmax) were reached in about 6.0 to 7.3 hours. Displays higher oral bioavailability compared to other SERMs with increased resistance to intestinal glucuronidation due to nonpolar tetrahydronaphthalene structure. In a comparative study in the rat, lasofoxifene showed bioavailability of 62%.
Route of Elimination
Primarily fecal excretion and secondarily renal elimination as mainly metabolites, with less than 2% excreted in urine as unchanged parent drug.
Volume of Distribution
The apparent volume of distribution in postmenopausal women is 1350L.
Clearance
The apparent oral clearance (CL/F) of lasofoxifene in postmenopausal women is approximately 6.6 l/hr.
Phase I oxidation via hepatic CYP3A4/CYP3A5 and CYP2D6 accounts for nearly half of total metabolism of lasofoxifene. Phase II conjugation reactions include glucuronidation and sulfation. Its glucuronidation is catalyzed by UGTs that are expressed in both the liver (UGT1A1, UGT1A3, UGT1A6, and UGT1A9) and the intestine (UGT1A8 and UGT1A10). Further metabolites of lasofoxifene detected in plasma are the glucuronide of a hydroxylated metabolite, and the methylated catechols.
Lasofoxifene has known human metabolites that include (2S,3S,4S,5R)-3,4,5-trihydroxy-6-[[(5R,6S)-6-phenyl-5-[4-(2-pyrrolidin-1-ylethoxy)phenyl]-5,6,7,8-tetrahydronaphthalen-2-yl]oxy]oxane-2-carboxylic acid.

Elimination half-life is approximately 6 days.
Lasofoxifene mediates an agonist effect on estrogen receptors expressed on bone to mimic the positive effects of estrogen to reduce the production and lifespan of osteoclasts via altering the NF-kappaB ligand (RANKL)/RANK/osteoprotegerin system, stimulation of osteoblast (the bone forming cells) activity and additional effects on calcium homeostasis. It acts as an antagonist at uterus and mammary glands by suppressing the estrogen signaling in oncogenic pathways and inhibits the downstream gene transcription. A study also suggests that lasofoxifene may also act as an inverse agonist at CB2 cannabinoid receptor which is expressed in bone to inhibit osteoclast formation and resorptive activity.

PharmaCompass offers a list of Lasofoxifene API manufacturers, exporters & distributors, which can be sorted by GMP, USDMF, JDMF, KDMF, CEP (COS), WC, Price,and more, enabling you to easily find the right Lasofoxifene manufacturer or Lasofoxifene supplier for your needs.
Send us enquiries for free, and we will assist you in establishing a direct connection with your preferred Lasofoxifene manufacturer or Lasofoxifene supplier.
PharmaCompass also assists you with knowing the Lasofoxifene API Price utilized in the formulation of products. Lasofoxifene API Price is not always fixed or binding as the Lasofoxifene Price is obtained through a variety of data sources. The Lasofoxifene Price can also vary due to multiple factors, including market conditions, regulatory modifications, or negotiated pricing deals.
A Lasofoxifene manufacturer is defined as any person or entity involved in the manufacture, preparation, processing, compounding or propagation of Lasofoxifene, including repackagers and relabelers. The FDA regulates Lasofoxifene manufacturers to ensure that their products comply with relevant laws and regulations and are safe and effective to use. Lasofoxifene API Manufacturers are required to adhere to Good Manufacturing Practices (GMP) to ensure that their products are consistently manufactured to meet established quality criteria.
A Lasofoxifene supplier is an individual or a company that provides Lasofoxifene active pharmaceutical ingredient (API) or Lasofoxifene finished formulations upon request. The Lasofoxifene suppliers may include Lasofoxifene API manufacturers, exporters, distributors and traders.
Lasofoxifene Active pharmaceutical ingredient (API) is produced in GMP-certified manufacturing facility.
GMP stands for Good Manufacturing Practices, which is a system used in the pharmaceutical industry to make sure that goods are regularly produced and monitored in accordance with quality standards. The FDA’s current Good Manufacturing Practices requirements are referred to as cGMP or current GMP which indicates that the company follows the most recent GMP specifications. The World Health Organization (WHO) has its own set of GMP guidelines, called the WHO GMP. Different countries can also set their own guidelines for GMP like China (Chinese GMP) or the EU (EU GMP).
PharmaCompass offers a list of Lasofoxifene GMP manufacturers, exporters & distributors, which can be sorted by USDMF, JDMF, KDMF, CEP (COS), WC, API price, and more, enabling you to easily find the right Lasofoxifene GMP manufacturer or Lasofoxifene GMP API supplier for your needs.
A Lasofoxifene CoA (Certificate of Analysis) is a formal document that attests to Lasofoxifene's compliance with Lasofoxifene specifications and serves as a tool for batch-level quality control.
Lasofoxifene CoA mostly includes findings from lab analyses of a specific batch. For each Lasofoxifene CoA document that a company creates, the USFDA specifies specific requirements, such as supplier information, material identification, transportation data, evidence of conformity and signature data.
Lasofoxifene may be tested according to a variety of international standards, such as European Pharmacopoeia (Lasofoxifene EP), Lasofoxifene JP (Japanese Pharmacopeia) and the US Pharmacopoeia (Lasofoxifene USP).
