Hymecromone (4-methylumbelliferone) is already approved drug in Europe and Asia where it is used to treat biliary spasm. It is used as choleretic and antispasmodic drugs and as a standard for the fluorometric determination of enzyme activity. The concomitant administration of Hymecromone with products, containing metoclopramide, leads to mutual decrease of their action. Due to a danger of diarrhea with subsequent hypokalemia, Hymecromone should be applied with caution to patients on cardiac glycosides therapy (in these cases the sensitivity to them is increased). Hymecromone can be administered simultaneously with otherspasmolytics and analgesics. Very rare allergic reactions, itching, erythema, rashes; diarrhea which normally disappears by reduction of dose or discontinuance of therapy.

4-Methylumbelliferone (4-MU/HYMECROMONE) inhibits hyaluronan synthesis and retards cancer spreading in experimental animals through mechanisms not fully understood. These mechanisms were studied in A2058 melanoma cells, MCF-7 and MDA-MB-361 breast, SKOV-3 ovarian and UT-SCC118 squamous carcinoma cells by analysing hyaluronan synthesis, UDP-glucuronic acid (UDP-GlcUA) content, and hyaluronan synthase (HAS) mRNA levels. The maximal inhibition in hyaluronan synthesis ranged 22-80% in the cell lines tested. Active glucuronidation of 4-MU produced large quantities of 4-MU-glucuronide, depleting the cellular UDP-GlcUA pool. The maximal reduction varied between 38 and 95%. 4-MU also downregulated HAS mRNA levels: HAS3 was 84-60% lower in MDA-MB-361, A2058 and SKOV-3 cells.
