Description

NOVEL PHARMACEUTICAL COMPOSITIONS
The present invention is related to proton pump inhibitors and alginic acid combinations and the usage of these combinations in treating gastro gastroesophageal reflux disease (GERD), peptic ulcer, duodenum ulcer, Zollinger-Ellison syndrome, and treating symptoms such as pain due to reflux of stomach acid and bile towards the esophagus and acid indigestion, reflux esophagitis, regurgitation and retrosternal pain and to pharmaceutical combinations comprising these combinations.
Particularly the invention is related to a pharmaceutical composition comprising alginic acid and a proton pump inhibitor selected from rabeprazole or omeprazole or lansoprazole and/or pharmaceutically acceptable derivatives thereof.
Rabeprazole is a proton pump inhibitor having a substituted benzimidazole structure which inhibits gastric acid secretion. The chemical name of rabeprazole is 2-[[[4-(3-methoxypropoxy)-3-methyl-2- pridinyl]-methyl]sulfinyl]-lH-benzimidazole and it has been described for the first time in the application numbered EP0268956. It has been described in said document that rabeprazole is effective in treating gastric ulcers.
Figure imgf000002_0001
Figure 1. Rabeprazole
Rabeprazole is marketed as 50 mg capsules, lOmg and 20mg enteric tablet forms.
Omeprazole is proton pump inhibitor which reduces gastric acid secretion. The chemical name of omeprazole is 5-Methoxy-2-(4-methoxy-3,5-dimethyl-2-pridinylmethyl-sulfinyl)benzimidazole and it has been described for the first time in the application numbered US4255431. In said document omeprazole has been described to be used in treating ulcer.
Figure imgf000003_0001
Figure 2. Omeprazole
Lansoprazole is a proton pump inhibitor which inhibits the enzyme system of gastric parietal cells and gastric acid secretion. The chemical name of Lansoprazole is 2-({3-Methyl-4-(2,2,2-trifluoroethoxy)- 2-pridinyl} sulfinyl benzimidazole, and it has been described for the first time with the application numbered US4628098. It has been described in said document that lansoprazole is effective in treating ulcers.

Figure 3. Lansoprazole The chemical name of alginic acid is Poly[beta-D-mannopyranosyluronic acid- (1- >4), alpha-L- glucopyranosyluronic acid- (1- >4) and it has been described for the first time with the application numbered US2128551. It has been described in said document that alginic acid is effective in treating pain due to stomach acid and reflux.
Figure imgf000003_0003
Figure 4. Alginic acid Alginic acid is marketed as an oral suspension comprising 200mg alginate in combination with carbonated compounds, a chewing tablet and powder form for a 225mg oral solution in combination with magnesium alginate.
It has been surprisingly discovered that an unexpected therapeutic benefit, particularly a synergistic therapeutic benefit can be obtained by a combination therapy in which an active agent selected from proton pump inhibitors and alginic acid is used in treating gastro gastroesophageal reflux disease (GERD), peptic ulcer, duodenum ulcer, Zollinger-Ellison syndrome, and treating the symptoms such as pain due to reflux of stomach acid and bile towards the esophagus and acid indigestion, reflux esophagitis, regurgitation and retrosternal pain. It is possible for said therapeutic benefit to be according to the following, when this combination is used in comparison to what is required when only alginic acid or a proton pump inhibitor is used in treatments;
• Reducing the required dosage in order to obtain the required therapeutic effect and/or
• Reducing undesired adverse effects and/or
• Observing therapeutic effect in a short period of time and/or
• Observing therapeutic effect for a long period of time and/or
• Providing a more effective treatment
• Increasing patient compatibility.
In other words it can be said that the pharmaceutical composition in which alginic acid and an active agent selected from a proton pump inhibitor is used simultaneously or together shows higher therapeutic benefits in comparison to compositions which use these two active agents separately.
Accordingly the present invention is a pharmaceutical composition comprising alginic acid as the active agent and an active agent selected from a proton pump inhibitor or pharmaceutically acceptable derivatives thereof.
According to another aspect, the combined usage of alginic acid and an active agents selected from a proton pump inhibitor ensures to see the therapeutic effect in a short period of time and ensures that this effect is stronger in comparison to these two active agents being used separately. By this means it is possible to provide a more effective treatment. Interestingly, these positive effects can be seen in combinations when these two active agents are given sequentially and said positive effects can be seen when these two active agents are given inside a dosage form at the same time or inside independent dosage forms simultaneously. High therapeutic benefits can also be observed as long term effects.
Accordingly the present invention is related to pharmaceutical compositions that comprise alginic acid together with rabeprazole, omeprazole, or lansoprazole selected from proton pump inhibitors in order to be used sequentially inside separate dosage forms, simultaneously inside separate dosage forms or simultaneously in the same dosage form.
On the other hand the invention is related to a pharmaceutical composition comprising the following as active agents; a) Alginic acid or pharmaceutically acceptable derivative and
b) Rabeprazole or pharmaceutically acceptable derivative.
On the other hand the invention is related to a pharmaceutical composition comprising the following as active agents; a) Alginic acid or pharmaceutically acceptable derivative and
b) Omeprazole or pharmaceutically acceptable derivative.
On the other hand the invention is related to a pharmaceutical composition comprising the following as active agents; a) Alginic acid or pharmaceutically acceptable derivative and
b) Lansoprazole or pharmaceutically acceptable derivative.
According to another aspect the present invention is related to pharmaceutical compositions that comprise an active agent selected from proton pump inhibitors a pharmaceutically efficient amount of alginic acid and at least one pharmaceutically acceptable agent.
The active agents can be provided as a combination inside a single composition together with at least a pharmaceutically acceptable excipient and they can also be formulized together with at least a pharmaceutically acceptable excipient in which the active agents are separate from each other. The different compositions that have been obtained can be combined in a single dosage form or can be prepared to be in separate dosage forms. If the compositions are in separate dosage forms said dosage forms can be the same as each other or they can be different from each other.
The present invention is related to using active agents suitable to the invention in order to prepare a medicine that can be used in combination therapy via being given sequentially or separately or simultaneously to treat gastro gastroesophageal reflux disease (GERD), peptic ulcer, duodenum ulcer, Zollinger-Ellison syndrome, and to treat symptoms such as pain due to reflux of stomach acid and bile towards the esophagus and acid indigestion, reflux esophagitis, regurgitation and retrosternal pain.
