Definitions

  • the present invention relates to solid pharmaceutical formulations comprising edoxaban as an active ingredient, in particular relating to tablets for oral administration, and to a process to prepare the same.
  • Edoxaban is the common name of the chemical compound N'-( 5 -chi oropy ri din-2- yl)-/V-[(lri',2f?,4ri)-4-(dimethylcarbamoyl)-2-[(5-methyl-6,7-dihydro-4iT-[l,3]thiazolo [5,4-c]pyridine-2-carbonyl)amino]cyclohexyl]oxamide, and has the chemical structure shown below.
  • anti-coagulant drug namely a direct factor Xa inhibitor, a class of anti coagulants comprising other drugs (“xabans”) such as rivaroxaban, apixaban and betrixaban, which was developed as an alternative to classic anti-coagulants such as heparin(s) and warfarin, due to the limitations in administration routes (heparins are injectable), and/or narrow therapeutic window (in the case of warfarin).
  • Edoxaban is a basic compound, and thus can be solubilized in strong acidic aqueous solution, however when the pH of the aqueous media is shifted to less acidic, neutral or basic values, the dissolution profile of edoxaban diminishes considerably.
  • patent document EP 2 140 867 Al discloses oral solid dosage forms, namely tablets coated or not, comprising edoxaban together with a sugar alcohol (mannitol) and/or a water-swelling additive, and other excipients.
  • mannitol sugar alcohol
  • use of sugar alcohols may be problematic in patients showing intolerance against these compounds, such as mannitol.
  • compositions where the sugar alcohol is replaced by other excipients such as a combination of a saccharide (lactose), and a starch (cornstarch) the dissolution profile of the resulting compositions at pH 4 (strong acidic medium) is not satisfactory.
  • Patent document EP 2 548 556 Al discloses that keeping the water content during granulation of edoxaban-containing material to 10% or less, leads to an improved dissolution profile in the neutral region of the pH scale. However, this improvement is only obtained in formulations having a sugar alcohol in its composition. As mentioned above, many patients show intolerance against sugar alcohols, such as mannitol. Yet, it is further known that these excipients also increase the gastrointestinal motility, leading to a decrease in drug absorption, which involves the risk of lower efficacy of the therapeutic ingredient.
  • Patent document EP 3 177 290 Al discloses tablet compositions comprising edoxaban in combination with a water-soluble vinylpyrrolidone polymer (copovidone, povidone) and a cellulose ether, free of a sugar alcohol.
  • a water-soluble vinylpyrrolidone polymer copovidone, povidone
  • a cellulose ether free of a sugar alcohol.
  • a water-soluble vinylpyrrolidone polymer affects the stability of the tablets. Because of its high peroxide content, vinylpyrrolidone polymers tend to oxidatively degrade the active ingredient and the excipients causing lower tablet stability, which results eventually in lower therapeutic efficacy.
