(1973) Ricerche sull'azione antihemorragica dell'Aminaphtone. Quad. Coagul. 15,38. Comments by the manufacturer of Capillarema® by U. Baldacci, Laboratori Baldacci, Pisa Aminaphtone is the generic name of 2-hydroxymethyl-l,4naphthohydroquinone-2- (p-aminobenzoate), C1S H 1s 04N. 33 and the structural formula is: OH 0 O-C Tni CH3 V NH 2 OH Aminaphtone is insoluble in water, soluble in acetone, ethanol and propylene glycol, and very sparingly soluble in ether, chloroform and benzene.

Animal and human pharmacology In rabbits, aminaphtone is excreted in the urine, mainly in the oxidized form. When the drug was given orally, 70-80% of the administered dose (100 mglkg) was recovered in the urine between 58 and 144 ho urs (Pepeu, 1975). No data are available about its absorption and metabolism in man. The toxicology of aminaphtone has been studied by Pepeu (1975) in mice, rats, rabbits and dogs. From these experiments it appears that the drug has a very low acute and long-term toxicity.

V. 01 Clinical experiments Amato et al.
