Pharmacology

Indication

Investigated for use/treatment in osteoporosis [1].

Structured Indications
Not Available
Pharmacodynamics

Increases bone mineral density and reduces risk of fractures in osteoporosis [2].

Mechanism of action

Odanacatib inhibits cathepsin K, likely by binding to its active site [7]. Cathepsin K is a cysteine protease enzyme which is secreted by osteoclasts [5]. Cathepsin K is responsible for the breakdown of collagen in the bone matrix as part of bone resorption. The inhibition of this enzyme results in decreased bone resorption without affecting bone deposition resulting in increased bone mineral density. This increased bone mineral density strengthens the bone which leads to fewer fractures in osteoporosis.

TargetActionsOrganism

inhibitor
Human
Absorption

Tmax of 2-6h [2]. The absolute bioavailabilities observed with 30mg and 50 mg doses are 70% and 30% respectively. When taken with high fat meals the 50mg dose's bioavailability increases to 49% and tmax increases to 10.5h [3].

Volume of distribution

100L [3]

Protein binding

97.5% bound to plasma proteins [4].

Metabolism

The major metabolite is the product of hydroxylation by CYP3A4 and CYP2C8 [4]. This metabolite is active but is 25 times less effective at inhibiting cathepsin K than odanacatib. The other metabolites are produced through glutathione conjugation, hydrolysis, dealkylation, glucuronidation, oxidation, and cyclization.

Route of elimination

16.9% excreted in urine. 74.5% excreted in feces.

Half life

Apparent half life observed to be 87.3-94.7h [2].

Clearance

Total clearance of 0.8L/h [3].

Toxicity

Odanacatib was found to increase the risk of stroke [1]. No further toxicological studies have been performed.
