Definitions

  • the invention relates to oral delayed-release pellets of duloxetine hydrochloride.
  • the invention further includes processes for their preparation and utilization.
  • Duloxetine hydrochloride (chemical name: (+)-(5)-N-methyl- ⁇ -(l-naphthyloxy)-2- thiophenepropylamine hydrochloride) is a selective serotonin and norepinephrine reuptake inhibitor (SS ⁇ RI) for oral administration.
  • Duloxetine hydrochloride has the following formula:
  • duloxetine hydrochloride can exist in two enantiomeric forms (R and S), with the S form being the more commercially desirable enantiomer due to its pharmacological activity.
  • the term "duloxetine hydrochloride” as used herein will refer to the S enantiomeric form unless otherwise specified.
  • CymbaltaTM as capsules containing delayed-release pellets for oral administration for the treatment of major depressive disorder (MDD), for the management of neuropathic pain associated with diabetic peripheral neuropathy and for the treatment of generalized anxiety disorder (GAD).
  • MDD major depressive disorder
  • GAD generalized anxiety disorder
  • duloxetine hydrochloride has been approved by EMEA as hard gastroresistant capsules under the name AriclaimTM and YentreveTM for the treatment of moderate to severe Stress Urinary Incontinence (SUI) for women and under the name Cymbalta M and Xeristar for the treatment of major depressive episodes and for treatment of diabetic peripheral neuropathic pain in adults.
  • United States Patent No. 5,508,276 encompasses an enteric duloxetine pellet which necessarily contains a core that includes duloxetine hydrochloride and an enteric layer that includes hydroxypropylmethylcellulose acetate succinate (HPMCAS). Due to the fact that duloxetine hydrochloride exhibits instability in acidic conditions and that the HPMCAS enteric polymer has free acidic groups in the final composition, these pellets require a separating layer between duloxetine hydrochloride- containing core and the enteric layer in order to avoid the degradation of duloxetine hydrochloride. Therefore, the separating layer serves to avoid direct contact between duloxetine hydrochloride and the enteric layer, and consequently to avoid the undesired reaction between each other. Indeed, no additional functionality of this separating layer in the release of the drug is recognized.
  • HPMCAS hydroxypropylmethylcellulose acetate succinate
  • the invention provides new delayed-release duloxetine hydrochloride pellets containing: i. an inert core; ii. a first layer including duloxetine hydrochloride and optionally one or more pharmaceutically acceptable excipients; iii. an intermediate layer including at least one cellulosic derivative polymer and optionally one or more pharmaceutically acceptable excipients; and iv. an enteric layer including an enteric polymer and optionally one or more pharmaceutically acceptable excipients.
  • the invention provides a process for preparing the above- described delayed-release pellets of duloxetine hydrochloride.
  • the process includes: i. applying to inert cores a first layer including duloxetine hydrochloride and optionally one or more pharmaceutically acceptable excipients; ii. applying to the obtained duloxetine hydrochloride-containing cores an intermediate layer including at least one cellulosic derivative polymer and optionally one or more pharmaceutically acceptable excipients; and iii. applying an enteric layer including an enteric polymer and optionally one or more pharmaceutically acceptable excipients.
  • the invention includes the use of above-described capsules containing the enteric pellets of duloxetine hydrochloride according to the invention for the treatment of major depressive disorder (MDD), for the management of neuropathic pain associated with diabetic peripheral neuropathy, for the treatment of generalized anxiety disorder (GAD) and for the treatment of moderate to severe Stress Urinary Incontinence (SUI) for women.

  • Inert cores are known and commonly used in pharmaceutical compositions and are also commercially available. These inert cores can be made from microcrystalline cellulose, mannitol or a mixture of sucrose and starch (commonly known as sugar spheres). The size range of these inert cores depends on the desired size of the final pellet.
  • Preferred inert cores are sugar spheres with a size from approximately 355 to approximately 500 micrometers.
  • the inert core is covered by a first layer containing duloxetine hydrochloride and optionally one or more pharmaceutically acceptable excipients.
  • a preferred pharmaceutically acceptable excipient is a polymer which allows the duloxetine hydrochloride to stick to the inert cores.
  • Preferred polymers include hydroxypropylmethylcellulose, methylcellulose, carboxymethylcellulose, polyvinylpirrolidone, xanthan gum acacia or gelatin.
  • a more preferred polymer is hydroxypropylmethylcellulose.
  • a preferred manner of coating the inert cores with the duloxetine hydrochloride is spraying a slurry suspension of duloxetine hydrochloride and the appropriate excipients in water.
  • coated cores can be made following this technique in a fluid bed dryer equipped with a
  • the preferred equipment is a fluid bed dryer equipped with a Wurster column.
  • this first layer can also be obtained by a "powder coating” process where the inert cores are moistened with a binder, duloxetine hydrochloride is added and mixed until homogeneous distribution, and the obtained cores are dried.
  • These coated cores could be made following this technique in a high shear granulator, in a non- perforated coating pan or in a fluidized bed dryer equipped with a rotary processor or with a rotating plate.
  • the intermediate layer includes a polymeric material.
  • the polymer used must be neutral.
  • the intermediate layer may also contain one or more pharmaceutically acceptable excipients.
  • a preferred neutral polymer is a cellulosic derivative polymer.
  • Preferred pharmaceutically acceptable excipients for the intermediate layer are sucrose and talc.
  • a preferred intermediate layer weight is from approximately 3% to approximately 60% of the weight of duloxetine hydrochloride-containing core (sugar spheres and duloxetine hydrochloride first layer).
  • a more preferred intermediate layer weight is from approximately 5% to approximately 6% of the weight of duloxetine hydrochloride- containing core (sugar spheres and duloxetine hydrochloride first layer).
  • the intermediate layer may be applied by spraying aqueous mixtures of the polymeric material with one or more pharmaceutically acceptable excipients.
  • a preferred method for applying this intermediate layer uses the fluidized bed dryer equipped with a Wurster column. Alternatively, a fluidized bed dryer equipped with a non-perforated coating pan could be used for applying this intermediate layer.
  • the enteric layer controls the place where the dissolution must be produced, i.e., the enteric formulation passes unchanged through the stomach of the patient, and the enteric layer is dissolved and allows delivery of the duloxetine hydrochloride when it leaves the stomach and enters into the small intestine.

  • Preferred pharmaceutically acceptable excipients with this enteric polymer are triethyl citrate, talc and titanium dioxide. Further, it has been observed that if titanium dioxide is not used as at least one of the pharmaceutically acceptable excipients with this enteric polymer (i.e. EudragitTM L30D55), the resultant duloxetine pellets show a lower dissolution profile as compared to the pellets contained in the commercially available duloxetine capsules (i.e., Cymbalta®).
  • talc as a pharmaceutically acceptable excipient with this enteric polymer can be optional, since the resultant duloxetine pellets show a dissolution profile very similar to the pellets contained in the commercially available duloxetine capsules (i.e., Cymbalta®).
