[Drugs inhibiting the hepatic fibrogenesis].
The treatment of chronic liver disease represents still now an open problem in medicine. The first objective of therapy has to be the causal agent removal; however, there are many cases (viral infections, autoimmunity, genetic disease) in which it is not possible to reach this issue; in these situations the secondary objective of the therapy is to inhibit the hepatic fibrogenesis, in attempt of easing or blocking the transformation of chronic liver disease in cirrhosis. The aim of this work is to review the various compounds which showed an antifibrotic activity, using a simple classification model, allowing a fast setting of different compounds. These last, on the basis of their main action, can be divided into two main groups: drugs with direct action, which interfere with collagen metabolism (for instance interferons, glucocorticoids, prolyl 4-hydroxylase inhibitors, cyclosporin A, colchicine, D-penicillamine, phosphatidylcholine and so on) and drugs with indirect action, that decrease the inflammatory stimuli, capable of stirring up the fibrogenetic hepatic process (S-adenosylmethionine, malotilate, ursodeoxycholic acid, ribavirin and so on). There are drugs that have both mechanisms of action, without the prevalence of one or other mechanism (prostaglandins).
