Abstract
The present invention pertains to a high drug load tablet comprising as active ingredient Compound I of formula or a pharmaceutically acceptable salt thereof in an amount from about 30% to 80% in weight of the active moiety based on the total weight of the tablet.
Claims
exact text as granted — not AI-modified1 - 15 . (canceled)
16 . A tablet comprising a pharmacologically effective amount of Compound I of formula (1)
or a pharmaceutically acceptable salt thereof in an amount from about 30% to 80% in weight of the active moiety based on the total weight of the tablet.
17 . A tablet according to claim 16 wherein Compound I of formula (1) or a pharmaceutically acceptable salt thereof is present in an amount from about 50% to 80% in weight of the active moiety based on the total weight of the tablet.
18 . A tablet according to claim 17 wherein Compound I of formula (1) is in the monomesylate salt form.
19 . A tablet according to claim 18 wherein Compound I of formula (1) monomesylate is in the beta crystal form thereof.
20 . A tablet according to claim 16 wherein the tablet comprises one or more pharmaceutically acceptable excipients suitable for the preparation of tablets.
21 . A tablet according to claim 20 wherein the excipient comprises at least one binder.
22 . A tablet according to claim 20 wherein the excipients comprise:
