Identification

Summary

Camostat is a serine protease indicated in Japan to treat chronic pancreatitis.

Generic Name
Camostat
DrugBank Accession Number
DB13729
Background

Camostat mesylate, or FOY-305, is a synthetic serine protease inhibitor.2,4 It was first described in the literature in 1981, as part of research on the inhibition of skin tumors in mice.8 Camostat mesylate inhibits cholecystokinin, pro-inflammatory cytokines, and serine proteases, leading to it being investigated for multiple indications including the treatment of COVID-19.6,7,1

Camostat mesylate was first approved in Japan in January 2006.9

Pharmacodynamics

Camostat mesylate is a protease inhibitor used to treat chronic pancreatitis.3 The duration of action is not long, as it is typically given in 3 divided doses daily.9 Patients should be counselled regarding the risk of anaphylaxis, thrombocytopenia, hepatic dysfunction, and hyperkalemia.9

Mechanism of action

In rats, oral camostat mesylate may increase pancreatic secretions and hypertrophy by increasing cholecystokinin release.6 Administration in rats has also lead to lower levels of IL-1beta, IL-6, TNF-alpha, TGF-beta, and PSC.7 Similar activity is seem after administration in humans, leading to reduced pain and inflammation as well as improve the function of the pancrease in chronic pancreatitis.9

In the case of SARS-CoV-2, camostat mesylate inhibits the action of the serine protease TMPRSS2, preventing the priming of the viral spike protein for attachment to ACE2, and entry into the cell.1

Absorption

A 200mg oral dose of camostat mesylate leads to the active metabolite reaching a Cmax of 87.1 ± 29.5 ng/mL, with a Tmax of 40 min, and an AUC of 10,400 ± 1,400 ng*min/mL.9

Volume of distribution

The volume of distribution at steady state of camostat mesylate is 0.34-1.31L/kg.2

Protein binding

Camostat mesylate is 25.8-28.2% protein bound to human serum proteins in vitro.9

Metabolism

Camostat mesylate is hydrolyzed by carboxyesterate to the active 4-(4-guanidinobenzoyloxy) phenylacetate.2,9 The active metabolite is further hydrolyzed by arylesterase to 4-guanidinobenzoic acid.2,9

Plasma membrane-anchored serine protease that cleaves at arginine residues (PubMed:32703818). Participates in proteolytic cascades of relevance for the normal physiologic function of the prostate (PubMed:25122198). Androgen-induced TMPRSS2 activates several substrates that include pro-hepatocyte growth factor/HGF, the protease activated receptor-2/F2RL1 or matriptase/ST14 leading to extracellular matrix disruption and metastasis of prostate cancer cells (PubMed:15537383, PubMed:25122198, PubMed:26018085). In addition, activates trigeminal neurons and contribute to both spontaneous pain and mechanical allodynia (By similarity)
