It works by selectively blocking the androgen receptor (AR), the biological target of the androgen sex hormones testosterone and dihydrotestosterone (DHT). It does not lower androgen levels. The medication can have some estrogen-like effects in men when used as a monotherapy due to increased estradiol levels. Bicalutamide is well-absorbed, and its absorption is not affected by food. The elimination half-life of the medication is around one week. It shows peripheral selectivity in animals, but crosses the blood–brain barrier and affects both the body and brain in humans.Bicalutamide was patented in 1982 and approved for medical use in 1995. It is on the World Health Organizations List of Essential Medicines. Bicalutamide is available as a generic medication. The drug is sold in more than 80 countries, including most developed countries. It is the most widely used antiandrogen in the treatment of prostate cancer, and has been prescribed to millions of men with the disease.
Oculocerebrorenal syndrome (also called Lowe syndrome) is a rare X-linked recessive disorder characterized by congenital cataracts, hypotonia, intellectual disability, proximal tubular acidosis, aminoaciduria and low-molecular-weight proteinuria. Lowe syndrome can be considered a cause of Fanconi syndrome (bicarbonaturia, renal tubular acidosis, potassium loss and sodium loss). Signs and symptoms
Boys with Lowe syndrome are born with cataracts in both eyes; glaucoma is present in about half of the individuals with Lowe syndrome, though usually not at birth. While not present at birth, kidney problems develop in many affected boys at about one year of age. Renal pathology is characterized by an abnormal loss of certain substances into the urine, including bicarbonate, sodium, potassium, amino acids, organic acids, albumin, calcium and L-carnitine. This problem is known as Fanconi-type renal tubular dysfunction. Genetics
This syndrome is caused by mutations in the OCRL gene which encodes an inositol polyphosphate-5-phosphatase. At least one mechanism by which these mutations cause this syndrome is by loss of its Rab-binding domain.This protein is associated with the primary cilia of the retinal pigment epithelial cells, fibroblasts and kidney tubular cells. This suggests that this syndrome is due to dysfunction of the cilia in these cells.
