The glucuronide conjugates of bicalutamide and its metabolites are eliminated from the circulation rapidly, unlike unconjugated bicalutamide.The pharmacokinetics of bicalutamide are not affected by consumption of food, a persons age or body weight, renal impairment, or mild-to-moderate hepatic impairment. However, steady-state levels of bicalutamide are higher in Japanese individuals than in white people. Chemistry
Bicalutamide is a racemic mixture consisting of equal proportions of enantiomers (R)-bicalutamide (dextrorotatory) and (S)-bicalutamide (levorotatory). Its systematic name (IUPAC) is (RS)-N-[4-cyano-3-(trifluoromethyl)phenyl]-3-[(4-fluorophenyl)sulfonyl]-2-hydroxy-2-methylpropanamide. The compound has a chemical formula of C18H14F4N2O4S, a molecular weight of 430.373 g/mol, and is a fine white to off-white powder.The acid dissociation constant (pKa) of bicalutamide is approximately 12. It is a highly lipophilic compound (log P = 2.92). At 37 °C (98.6 °F), or normal human body temperature, bicalutamide is practically insoluble in water (4.6 mg/L), acid (4.6 mg/L at pH 1), and alkali (3.7 mg/L at pH 8). In organic solvents, it is slightly soluble in chloroform and absolute ethanol, sparingly soluble in methanol, and freely soluble in acetone and tetrahydrofuran.Bicalutamide is a synthetic and nonsteroidal compound which was derived from flutamide. It is a bicyclic compound (has two rings) and can be classified as and has variously been referred to as an anilide (N-phenylamide) or aniline, a diarylpropionamide, and a toluidide. Analogues
First-generation NSAAs including bicalutamide, flutamide, and nilutamide are all synthetic, nonsteroidal anilide derivatives and structural analogues of each other. Bicalutamide is a diarylpropionamide while flutamide is a monoarylpropionamide and nilutamide is a hydantoin. Bicalutamide and flutamide, though not nilutamide, can also be classified as toluidides.

Alpha-mannosidosis
Beta-mannosidosis
