Da Dalton; Mw molecular weight. a According to the Swiss pharmaceutical compendium. b HES mean molecular weight 130,000 Dalton, substitution grade 0.4. HES is cleaved by serum amylases and then excreted by the kidneys. c Acetate is metabolised to bicarbonate causing metabolic alkalosis. 1 SFR corresponds to 0.96 EUR or 1.05 USD.
