ASA. The studies refered to include long term administration to rats and ferrets and carcinogenicity studies in the mouse and rat. Notwithstanding the above, a programme of toxicological evaluation of balsalazide has been designed to fulfil the present day requirements of the major Regulatory Agencies World Wide. This programme includes re-evaluation of the consequences of repeated administration to rodents and non-rodents, reproduction toxicology and necessary toxicokinetics to enable overall evaluation. To date the initial findings in preliminary studies using high doses of balslazide at large multiples of the proposed dose for man, are substantiating the balsalazide has a low order of toxicity. /s/ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇.▇▇▇▇▇.
