  • Sachet formulation of the invention has been described as providing easy application, desired solubility and a dissolution rate, desired level of bioavailability and a formulation not leading to flowability -related problems.
  • Tablet forms are the most widely used solid dosage forms because of their advantages such as providing unit dosage forms with accurate and stable dose, great precision, less variability; protection of medicaments from atmospheric conditions like air, moisture and light; prolonged stability to medicaments with respect to physical, chemical and microbiological attributes; cheap oral dosage form due to the low manufacturing, packing and storage cost as compare to other solid dosage forms; easy to handle manufacturing; large scale production. Therefore, tablet forms are preferable compared to above-mentioned alternative dosage forms.
  • Eslicarbazepine acetate exhibits some problems on industrial-scale. Eslicarbazepine acetate has extremely low bulk density leading to poor flowability. When the particles are compressed, brittle behaviour has been observed. Due to its low plastic deformation ability, compressibility is low and flowability is very, very poor. Therefore, it can be difficult to handle and compress. Eslicarbazepine acetate is also reported to be poorly soluble in water which leads to poor dissolution and administration of a high dose of the drug in order to achieve desired therapeutic effect. Poor aqueous solubility, flowability, compressibility and high dose of the drug lead to technical challenges in the development of a desired formulation. These difficulties indicate that there is still a need for alternative formulations of eslicarbazepine acetate with enhanced solubility, flowability and compressibility together with stability and longer shelf life.
  • the present invention relates to a pharmaceutical composition of eslicarbazepine acetate, wherein the composition comprises a mixture of eslicarbazepine acetate, at least one binder and optionally at least one further pharmaceutically acceptable excipient subjected to at least two times compaction and dry granulation.
  • the present invention relates to a method of preparing a pharmaceutical composition of eslicarbazepine acetate, wherein the method comprises following steps:
  • the present invention relates to a pharmaceutical composition of eslicarbazepine acetate, wherein the composition comprises a mixture of eslicarbazepine acetate, at least one binder and optionally at least one further pharmaceutically acceptable excipient subjected to at least two times compaction and dry granulation, for use as an anticonvulsant.
  • Eslicarbazepine acetate has a low bulk density being 0.18 - 0.47 g/ml. It has been observed that particles of the active ingredient usually exhibit brittle behaviour when compressed. Because the active ingredient exhibits very little plastic deformation, compactibility characteristic is not good. Little or no powder flow has been observed. Because Carr’s index is greater than 42%, flowability is considered to be“very, very poor” (USP ⁇ 1174>). Even when the inventors tried to reduce the concentration of the active ingredient to 66.7%, powder could not flow through 15 mm funnel. Futhermore, bulk density of such a powder mixture being 0.35 - 0.45 g/ml had a volume of 2.7 - 3.4 ml. Accordingly, swallowing these large-sized tablets would be difficult. Therefore, direct powder mixing and direct compression methods were not suitable in the preparation of the pharmaceutical compositions of eslicarbazepine acetate.
  • Briquette press has been performed at the first trial of dry granulation method. However, powder flow was so poor that compressing the tablets under fixed compression force was not possible. Because the amount of the powder filled into die cavity was not consistent, some of the pressed tablets were hard, some were soft. Low-weight tablets were more friable. Inventors performed other trials in order to provide good flow, but failed. Accordingly, briquette press has not been found applicable.
  • the present invention relates to a pharmaceutical composition of eslicarbazepine acetate, wherein the composition comprises a mixture of eslicarbazepine acetate, at least one binder and optionally at least one further pharmaceutically acceptable excipient subjected to at least two times compaction and dry granulation.
