Definitions
- This invention relates to pharmaceutical formulations having two or more pharmaceutical layers interspersed with one or more intermediate layers, wherein the pharmaceutical layers include, but are not limited to, pharmaceutical compositions useful for affecting weight loss, suppressing appetite and/or treating obesity-related conditions in individuals.
- Certain types of layered tablets are known in pharmaceutical applications. Some pharmaceutical applications separate potentially interacting layers from one another within a tablet.
- U.S. Patent No. 6,576,256 discloses separating potentially interacting compounds from each other using separate flat layers of a tablet, concentric layers, coated beads or granules, and/or using buffers.
- Thombre, A. G., L. E. Appel, et al. (2004), "Osmotic drug delivery using swellable-core technology" J. Control Release 94(1): 75-89 discloses a core tablet containing a drug and a water- swellable component, and one or more delivery ports in different core configurations including a tablet-in-tablet (TNT) bilayer and trilayer formation.
- TNT tablet-in-tablet
- Patent No. 6,706,283 discloses an osmotic delivery device fabricated in a bilayer geometry, wherein the core comprises a sweller layer "sandwiched" between two drug layers.
- the coating of a bilayer tablet may include a water permeable membrane, but is substantially impermeable to the drug and/or the excipients contained therein.
- U.S. Patent No. 6,630,165 discloses dosage forms and methods for providing sustained release reboxetine including a trilayered compressed core with a first component drug layer, a second component push layer and a third component barrier layer separating the drug layer from the push layer.
- the barrier layer is inert with the respect to the composition of the drug layer and substantially impermeable, such that the drug and the components of the push layer are prevented from mixing.
- one type includes a first layer to provide immediate release of a drug and a second layer to provide controlled-release of the drug.
- U.S. Patent No. 6,514,531 discloses coated trilayer immediate/prolonged release tablets comprising Zolpidem hemitartrate.
- U.S. Patent No. 6,087,386 discloses a trilayer tablet with an enalapril layer, a losartan potassium layer and a second enalapril maleate layer or an excipient layer.
- U.S. Patent No. 6,926,907 discloses a trilayer tablet that separates famotidine contained in a film coat from a core comprising controlled-release naproxen formulated using excipients which control the drug release.
- the film coat is an enteric coating configured to delay the release of naproxen until the dosage form reaches an environment where the pH is above four.
- An embodiment provides a layered pharmaceutical formulation comprising two or more pharmaceutical layers and an intermediate layer disposed between at least two of the two or more pharmaceutical layers.
- the intermediate layer is configured to dissolve in vivo to thereby leave the two or more pharmaceutical layers substantially intact, but physically separated, essentially forming two distinct pills.
- the dissolution rate of one of the separated two or more pharmaceutical layers is substantially similar to that of a singly compressed tablet comprising the same pharmaceutical composition as that of the pharmaceutical layer.
- Figure IA illustrates an embodiment of a layered pharmaceutical formulation.
- Figures IB & 1C illustrate the layered pharmaceutical formulation of Figure IA in progressive stages as an intermediate layer dissolves.
- Figure 2 A illustrates a second embodiment of a layered pharmaceutical formulation.
- Figure 2B illustrates the second embodiment of Figure 2A after an intermediate layer dissolves.
- Figure 3 illustrates a third embodiment of a layered pharmaceutical formulation.
- Figure 4 illustrates a fourth embodiment of a layered pharmaceutical formulation.
- Figure 5 illustrates a fifth embodiment of a layered pharmaceutical formulation with multiple intermediate layers.
- Figure 6 illustrates a sixth embodiment of a layered pharmaceutical formulation with lenticular shaped layers.
- Figure 7 illustrates a seventh embodiment of a layered pharmaceutical formulation.
- a layered pharmaceutical formulation comprises two or more pharmaceutical layers and at least one intermediate layer disposed between at least two of the two or more pharmaceutical layers.
- the at least one intermediate layer is configured to dissolve in vivo to thereby leave the two or more pharmaceutical layers substantially intact.
- the dissolution rate of one or more of a separated pharmaceutical layer is substantially similar to that of a singly compressed tablet comprising the same pharmaceutical composition as that of the pharmaceutical layer. The separated pharmaceutical layer thus has an independent and predictable dissolution profile.
- a dissolution profile for a drug comprises the known dissolution rate and particular dissolution characteristics of the drug.
- a predictable dissolution profile for a specific drug allows for more accurate treatment of a given symptom.
- Predictable dissolution profiles for different drugs within a multilayer tablet allow for coordinated treatment of multiple symptoms with a single pharmaceutical formulation.
- multilayer pharmaceutical formulations present challenges in maintaining predictable dissolution profiles.
- in vivo conditions often disrupt an otherwise predictable multilayer pharmaceutical formulation dissolution profile.
- a multilayer tablet may be manufactured with drugs of known dissolution profiles. Once the multilayer tablet is ingested by a patient, however, there is no guarantee that each drug will dissolve as predicted by its individual dissolution profile. Drug configuration within a tablet, tablet shape, excipients or fillers in the tablet, tablet coatings and in vivo conditions may all affect the dissolution profiles. Additionally, interaction between different drugs within a multilayer tablet may cause a change in dissolution profile for one or more compositions within the multilayer tablet.
- the multilayer tablet becomes attached to the lining of the stomach, only a portion of the tablet would be exposed to the stomach fluids.
- the dissolution of the exposed portion of the tablet may occur at a more predictable rate while the unexposed portion of the multilayer tablet shielded from the stomach fluids would have a longer dissolution profile than would otherwise be expected from a singly compressed tablet of an identical composition.
- having a multilayer tablet is desirable for ease of administration of multiple pharmaceutical compositions within a single tablet.
- a pharmaceutical formulation comprising two or more pharmaceutical layers and at least one intermediate layer configured to dissolve in vivo to thereby leave the two or more pharmaceutical layers substantially intact.
- the dissolution rate of one or more of the separated pharmaceutical layers is substantially similar to that of a singly compressed tablet comprising the same pharmaceutical composition as that of the pharmaceutical layer.
- the pharmaceutical layer comprises a single pharmaceutically active compound or drug.
- the pharmaceutical layer comprises a pharmaceutical composition.
- pharmaceutical composition refers to a mixture of a chemical compound or compounds (e.g., a drug or drugs) with additional pharmaceutical components, such as diluents or carriers.
- compositions facilitates administration of the drug to an organism.
- Pharmaceutical compositions can also be obtained in the form of pharmaceutically acceptable salts by reacting drug compounds with inorganic or organic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid and the like.
- the two or more pharmaceutical layers comprise one or more immediate-release formulations.
- immediate-release is used herein to specify that the immediate release formulation is not configured to alter the dissolution profile of the pharmaceutical layer.
- an immediate release pharmaceutical layer may be a pharmaceutical composition that does not contain ingredients included for the purpose of altering the dissolution profile.
- the two or more pharmaceutical layers comprise one or more controlled-release formulations.
- controlled-release is used herein in its ordinary sense and thus includes pharmaceutical compositions combined with ingredients to alter their dissolution profile.
- a "sustained-release" formulation is a type of controlled-release formulation, wherein ingredients have been added to a pharmaceutical composition such that the dissolution profile is extended over a longer period of time than that of an immediate release formulation comprising a similar pharmaceutical composition.
- the at least one intermediate layer is a flat layer separating at least two pharmaceutical layers.
- the at least one intermediate layer has exposed edges. Exposed edges allow for fluid to contact and dissolve the at least one intermediate layer.
- the pharmaceutical formulations comprises a coating covering the two or more pharmaceutical layers and the at least one intermediate layer. The coating is configured to dissolve in vivo more or less uniformly over the two or more pharmaceutical layers and the at least one intermediate layer such that the at least one intermediate layer is left exposed to the fluids that will dissolve the at least one intermediate layer in vivo.
- the at least one intermediate layer is or comprises an impermeable membrane. In some embodiments the at least one intermediate layer has a substantially higher dissolution rate than at least one of the pharmaceutical layers. In some preferred embodiments the at least one intermediate layer dissolves in a nearly immediate fashion with respect to the dissolution of at least one of the pharmaceutical layers. In some embodiments the at least one intermediate layer comprises at least one of a monosaccharide or a disaccharide sugar, a starch (e.g., corn or potato starches), or any other suitable tablet ingredients known in the art. In some preferred embodiments the at least one intermediate layer comprises lactose.
- the intermediate layer dissolves in a nearly immediate fashion as compared to the dissolution rates of the respective pharmaceutical layers, e.g., such that upon dissolution of the intermediate layer, substantially all of the surface area of each of the two pharmaceutical layers is exposed.
- the immediate release layer is dissolved to the extent that at least two pharmaceutical layers present in the pharmaceutical formulation are separated in less than 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25 or 30 minutes.
- compositions of drugs can be configured in various ways and in a variety of dosage forms to modify a dissolution rate of the drug.
- one type of controlled-release pharmaceutical formulation is a sustained-release pharmaceutical formulation.
- Sustained-release pharmaceutical formulations can contain a variety of excipients, such as retardant excipients (also referred to as release modifiers) and/or fillers that are selected and incorporated into the formulation in such a way as to slow the dissolution rate of the formulation (and thereby slow the dissolution and/or release of the zonisamide) under in vivo conditions as compared to an otherwise comparable immediate-release formulation.
- a "comparable" immediate-release formulation is one that is substantially identical to the controlled-release formulation, except that that it is configured to provide immediate-release instead of controlled-release under substantially identical conditions.
- immediate-release is used herein to specify a formulation that is not configured to alter the dissolution profile of the active ingredient (e.g., zonisamide, bupropion, naltrexone, olanzapine, phentermine, topiramate, metformin, fluoxetine).
- an immediate-release pharmaceutical formulation may be a pharmaceutical formulation that does not contain ingredients that have been included for the purpose of altering the dissolution profile.
- An immediate-release formulation thus includes drug formulations that take less than 30 minutes for substantially complete dissolution of the drug in a standard dissolution test.
- a "standard dissolution test,” as that term is used herein, is a test conducted according to United States Pharmacopeia 24th edition (2000) (USP 24), pp.
- controlled-release is used herein in its ordinary sense and thus includes pharmaceutical formulations that are combined with ingredients to alter their dissolution profile.
- a "sustained-release” formulation is a type of controlled-release formulation, wherein ingredients have been added to a pharmaceutical formulation such that the dissolution profile of the active ingredient is extended over a longer period of time than that of an otherwise comparable immediate-release formulation.
- a controlled-release formulation thus includes drug formulations that take 30 minutes or longer for substantially complete dissolution of the drug in a standard dissolution test, conditions which are representative of the in vivo release profile.
- a pharmaceutical layer may be configured in various ways. For example, in some embodiments a layer comprises a flat portion of a pharmaceutical formulation. In some embodiments a layer comprises a rounded portion of a pharmaceutical formulation. In some embodiments a layer comprises a conical section of a pharmaceutical formulation. In some embodiments a layer comprises an elliptical section of a pharmaceutical formulation. In some embodiments a layer comprises a sideways section of a pharmaceutical formulation. In some embodiments a layer comprises a cubical section of a pharmaceutical formulation. In some embodiments a layer comprises a wedge of a pharmaceutical formulation. In some embodiments a layer comprises a substantial portion of a pharmaceutical formulation. A substantial portion is preferably at least about 25% of the pharmaceutical formulation and more preferably at least about 50% of the pharmaceutical formulation.
- At least one pharmaceutical layer reacts when brought into contact with another of the pharmaceutical layers within the layered pharmaceutical formulation. In some embodiments at least one pharmaceutical layer does not react when brought into contact with another of the pharmaceutical layers.
- an intermediate layer is configured to dissolve in vivo.
- Dissolving is the act of solvation wherein a solute is dissolved in a solvent to create a solution.
- Dissolving in vivo means that the dissolving takes place within an organism or within living tissue either taken from or part of an organism.
- An organism is any living animal, plant, bacteria or fungus. In preferred embodiments the organism is human.
- a dissolving intermediate layer separates at least two of the pharmaceutical layers.
- the two pharmaceutical layers contain different pharmaceutical compositions.
- the pharmaceutical layers are no longer held together within the pharmaceutical formulation.
- the pharmaceutical layers remain substantially intact.
- a pharmaceutical layer remains substantially intact when it retains at least about 50% of its original mass in a single entity post-dissolution of the one or more intermediate layers.
- the pharmaceutical layer remains substantially intact when it retains at least about 75% of its original mass post-dissolution of the one or more intermediate layers.
- the pharmaceutical layer remains substantially intact when it retains at least about 85% of its original mass post- dissolution of the one or more intermediate layers.
- each pharmaceutical layer has a different dissolution rate.
- a dissolution rate is the solvation of a pharmaceutical layer volume per unit time.
- one or more pharmaceutical layers have similar dissolution rates.
- the one or more intermediate layers have a higher dissolution rate than the two or more pharmaceutical layers.
- Figure IA illustrates a preferred embodiment of a pharmaceutical formulation 100.
- the pharmaceutical formulation 100 comprises two pharmaceutical layers 102 A and 102B.
- Pharmaceutical layer 102 A comprises a pharmaceutical composition.
- the pharmaceutical layer 102B comprises the same pharmaceutical composition as that of the pharmaceutical layer 102 A.
- the pharmaceutical layer 102 A comprises a different pharmaceutical composition than that of the pharmaceutical layer 102B.
- the pharmaceutical formulation 100 also comprises an intermediate layer 106. In the illustrated embodiment the intermediate layer 106 is configured to dissolve in vivo.
- Each of the pharmaceutical layers 102 A and 102B comprises one or more pharmaceutical compositions. As illustrated in the pharmaceutical formulation 100, the dosage amount of each pharmaceutical layer 102 A and 102B is similar. The dosage strength of each pharmaceutical layer may also be similar. In other embodiments the dosage amount and/or strength of one pharmaceutical layer is much greater than that of another layer. This difference in dosage amount or strength allows for individualized treatment of symptoms that are addressed by increasing or decreasing a dosage of one or more pharmaceutical layers while maintaining a dosage of other layers. The amount or strength of dosage of a drug contained within a pharmaceutical formulation will, of course, be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgment of the prescribing physician.
- the illustrated pharmaceutical formulation 100 includes, but is not limited to, drugs for affecting weight loss, suppressing appetite and/or treating an obesity-related condition in a patient.
- the illustrated pharmaceutical layer 102 A comprises zonisamide and the pharmaceutical layer 102B comprises bupropion.
- the intermediate layer 106 comprises lactose or a suitable monosaccharide sugar, disaccharide sugar or a starch.
- one or more of the pharmaceutical layers comprises naltrexone
- one or more of the pharmaceutical layers comprises bupropion
- at least one intermediate layer comprises a monosaccharide sugar, a disaccharide sugar or a starch.

- Zonisamide is a marketed anticonvulsant indicated as adjunctive therapy for adults with partial onset seizures. Without being bound by any particular theory, it is believed that the mechanism of antiepileptic activity appears to be: (1) sodium-channel blocking; and (2) reduction of inward T-type calcium occurrence.
- zonisamide binds to the GABA/benzodiazepine receptor complex without producing change in chloride flux. Further, zonisamide facilitates serotonergic and dopaminergic neurotransmission and possesses a weak inhibitory effect on carbonic anhydrase.
- Zonisamide has been shown to cause significant weight loss (comparable to marketed weight loss medications) in patients presenting primary obesity. It has been postulated that the affect of zonisamide on the CNS concentration of serotonin, dopamine and carbonic anhydrase is responsible for this effect. There is evidence that zonisamide increases serotonin and dopamine synthesis rates herein. There is further evidence suggesting that zonisamide stimulates dopamine D 2 receptors.
- Zonisamide can be formulated in a controlled- or sustained-release tablet or gel form. This allows a patient newly prescribed zonisamide to ramp up the dosage level over a period of several days. This increase in dosage form allows the patient to avoid some of the negative side effects that have been exhibited during the initial administration of zonisamide to a patient. Some of these initial side effects include a shock to the body. Although patients who start with a full dose of zonisamide will become acclimated to the dosage over a period of time, the negative side effects accompanying the initial shock to the body can be avoided with a method wherein dosages are increased over a period of several days.
- a method of administering sustained-release zonisamide in a layered tablet can reduce shock to the body while maximizing bioavailability, and thus have a maximum effect for prevention of weight gain and/or treatment of obesity.
- the anticonvulsant is a ⁇ -amino butyric acid (GABA) inhibitor, a GABA receptor antagonist or a GABA channel modulator.
- GABA inhibitor it is meant a compound that reduces the production of GABA in the cells, reduces the release of GABA from the cells, or reduces the activity of GABA on its receptors, either by preventing the binding of GABA to GABA receptors or by minimizing the effect of such binding.
- the GABA inhibitor may be a 5-HTlb agonist or another agent that inhibits the activity of NPY/AgRP/GABA neurons.
- the GABA inhibitor may suppress the expression of the AgRP gene, or the GABA inhibitor may suppress the production or release of AgRP. It is, however, understood that a 5 -HT Ib agonist may inhibit the NPY/AgRP/GABA neuron (and therefore activate pro-opiomelanocortin (POMC) neurons) without acting as an inhibitor of the GABA pathway.
- POMC pro-opiomelanocortin
- the GABA inhibitor increases the expression of the POMC gene. In some of these embodiments, the GABA inhibitor increases the production or release of POMC protein. In certain other of these embodiments, the GABA inhibitor increases the activity on POMC expressing neurons.
- the GABA inhibitor is topiramate.
- Topiramate whose chemical name is 2,3:4,5-Bis-O-(l-methylethylidene)-beta-D-fructopyranose sulfamate, is often used to treat epilepsy, Lennox-Gastaut syndrome (a disorder causing seizures and developmental delays), neuropathic pain, bipolar disorder, obesity including reduction of binge eating, alcoholism, Post Traumatic Stress Disorder, infantile spasm, bulimia nervosa, or obsessive-compulsive disorder or to assist smoking cessation or prevent migraines.
- initial doses of topiramate are low and increased in slow steps. The usual initial dose is 25 to 50 mg daily in 2 single doses. Recommended increments vary, but are usually between 25 mg and 50 mg every 1 or 2 weeks. Common doses for maintenance treatment include, but are not limited to doses of approximately 100 to 200 mg daily.

- the opioid antagonist is selected from the group including, but not limited to alvimopan, norbinaltorphimine, nalmefene, naloxone, naltrexone, methylnaltrexone, and nalorphine, and pharmaceutically acceptable salts or prodrugs thereof.
- the opioid antagonist is a partial opioid agonist.
- Compounds of this class have some agonist activity at opioid receptors. However, because they are weak agonists, they function as de-facto antagonists.
- partial opioid agonists include, but are not limited to pentacozine, buprenorphine, nalorphine, propiram, and lofexidine.
