Description
FORMULATIONS COMPRISING CEFIXIME AS ACTIVE AGENT
The present invention relates to pharmaceutical tablet formulations comprising cefixime to be used in the treatment of infectious diseases caused by gram positive and gram negative bacteria. Cefixime was first disclosed in the patent application numbered EP0030630 (Bl). In said document, cefixime was indicated to be effective in the treatment of infectious diseases caused by gram positive and gram negative bacteria.
Cefixime is available in the form of 200 and 400 mg oral tablets or oral suspension on the market. In the sense of pharmaceutical technology, physical properties of the dosage form for every type of tablet dosage form are directly related to durability in storage conditions; dissolution and bioavailability of the dosage form obtained.
Tablet hardness is an important physical parameter in pharmaceutical tablet formulations and is related to resistance of tablets to storage, transport, coating and erosion-breakage before usage. Tablets with low hardness are more exposed to erosion, friability or breakage and this case leads;
I. To loss of active agent and thus decrease of the amount of dose taken;
II. To erosion of tablet surface during coating process and to dosage forms which have uneven surfaces and variable amounts of active agent in the final product while producing coated tablet forms.
On the other hand, there is a close connection between tablet hardness and dispersibility and solubility of a tablet. Tablets that are too hard do not disperse or dissolve adequately; in this case, bioavailability of said dosage forms will decrease and therefore the time for desired biological response to occur will extend. The same case is also true for all types of tablets such as effervescent, film-coated, soluble, extended-release, modified-release, delayed-release tablets etc.
Attaining appropriate tablet hardness is influenced by many parameters such as the types of active agents and excipients used, particle sizes thereof, flowability of the powder or granules prepared for tablet compressing and tablet compression force.
As a result of the development studies they conducted on pharmaceutical tablet formulations comprising cefixime, the inventors have found that the most perfect mechanical tablet resistance, the most appropriate dissolution rate and accordingly the highest bioavailability are attained with the tablet formulations that have a tablet hardness value between 3 kP and 50 kP.
According to this, another characteristic of the tablet formulations of the present invention is that said tablet formulations comprise cefixime as active agent and at least one pharmaceutically acceptable excipient, and the value of tablet hardness is between 3 kP and 50 kP. Another characteristic of the tablet formulations of the present invention is that said tablet formulations comprise cefixime as active agent and at least one pharmaceutically acceptable excipient, and the value of tablet hardness is between 4 kP and 40 kP.
Another characteristic of the tablet formulations of the present invention is that said tablet formulations comprise cefixime as active agent and at least one pharmaceutically acceptable excipient, and the value of tablet hardness is between 5 kP and 30 kP.
