Abstract

Cilj predmetnog pronalaska su kristalni polimorfni oblici antibiotika rifaksimina (INN), koji su označeni kao rifaksimin δ i rifaksimin ε, koji su korisni u proizvodnji medicinskih preparata koji sadrže rifaksimin za oralnu i topijsku primenu i dobijaju se postupkom kristalizacije, koja podrazumeva rastvaranje sirovog rifaksimina u vrućem etil alkoholu i izazivanje kristalizacije proizvoda dodavanjem vode na određenoj temp. i tokom određenog vremena, a nakon toga se sušenje izvodi pod kontrolisanim uslovima dok se ne postigne željeni sadržaj vode u krajnjem proizvodu.
