Abstract

Description
A PROCESS FOR PRODUCTION OF PHARMACEUTICAL (EFFERVESCENT) COMPOSITION
COMPRISING ALPHA - GLUCOSIDASE INHIBITOR (E.G. VOGLIOBOSE AND METFORMIN)
The present invention relates to a process used for production of effervescent formulations comprising an alpha-glucosidase inhibitor derivative active agent so as to be used in the prophylaxis and treatment of type 2 diabetes (non-insulin dependent) mellitus cases wherein hyperglycemia cannot be controlled by diet or exercise.
Primary active agents known as alpha-glucosidase inhibitors are voglibose, acarbose and miglitol.
In order to enable sufficient dispersion in water, effervescent formulations comprise high amounts of effervescent acid and effervescent base. Alpha-glucosidase inhibitor agents such as voglibose, acarbose or miglitol are not durable against acidic agents. This problem could be solved by using the acidic agents in small amounts. However, use of small amounts of acidic agents causes the obtained dosage forms to have longer dispersion times than expected and this poses problems for users and producers who have to attain quality standards.
Adding an effervescent acid into the formulation in the required amount to enable dispersion in sufficient time, on the other hand, leads to decrease in stability of the formulation during storing. This stability decrease is observed as impurity increase in the unit dosage form.
When the prior art is taken into consideration, there is need for new processes that can be used for production of effervescent formulations comprising one of the alpha-glucosidase inhibitors such as voglibose, acarbose or miglitol so as to be used for obtainment of stabile products having the required dispersion times. The present invention relates to a method for use in production of effervescent formulations comprising voglibose, acarbose or miglitol as active agent, characterized in that said method comprises the steps of;
• Granulating the mixture comprising at least one effervescent acid, at least one effervescent base and at least one pharmaceutically acceptable excipient and granulation solvent with a granulation solution comprising optionally one or more excipients, and then drying it
• Dry-mixing the alpha-glucosidase inhibitor (voglibose, acarbose or miglitol) and at least one excipient with the obtained granules.

IV. - Drying the granules
V. Adding voglibose, acarbose or miglitol and at least one excipient into the obtained granules and mixing them together
VI. Filling the formulation obtained into sachets or compressing it in tablet form.
