Definitions
- the present invention relates to pharmaceutical formulations comprising cefpodoxime proxetil and clavulanic acid for use in the treatment of upper respiratory infections such as tonsillitis, sinusitis, pharyngitis, otitis media; lower respiratory tract infections such as uncomplicated upper and lower urinary tract infections, uncomplicated gonococcal urethritis, skin and soft tissue infections.
- upper respiratory infections such as tonsillitis, sinusitis, pharyngitis, otitis media
- lower respiratory tract infections such as uncomplicated upper and lower urinary tract infections, uncomplicated gonococcal urethritis, skin and soft tissue infections.
- Said formulations are characterized in that they are in tablet form.
- Cefpodoxime proxetil was first disclosed in the application numbered EP00491 18. It has been disclosed in said document that use of cefpodoxime proxetil is effective in treatment of infection related diseases caused by gram positive and gram negative bacteria.
- Cefpodoxime proxetil is found in the form of granules for oral suspension comprising 40 mg / 5 ml, 50 mg / 5 ml and 100 mg / 5 ml cefpodoxime; powder for oral suspension comprising 40 mg / 5 ml cefpodoxime and tablet comprising 100 mg, 200 mg cefpodoxime on the market.
- cefpodoxime proxetil The solubility of cefpodoxime in aqueous media is very low due to its hydrophobic characteristic.
- formulations comprising cefpodoxime proxetil are compressed in tablet form, it has been observed that the active agent in said tablet form cannot be dissolved completely in the body fluid. Therefore, tablets comprising cefpodoxime proxetil cannot be easily and quickly dissolved in the body. This results in a decrease in the absorbance and the bioavailability of the drug and impedes the efficiency of the treatment.
- a cephalosporin antibiotic such as cefpodoxime proxetil and a beta- lactamase inhibitor such as clavulanic acid are used together as a combination.
- said low solubility and slow disintegration problems of formulations comprising cefpodoxime proxetil known in the state of the prior art, become more apparent in the presence of clavulanic acid as second active agent.
- Clavulanic acid is known as a hygroscopic and moisture absorbent molecule.
- tablet formulations comprising cefpodoxime proxetil and clavulanic acid combination dissolve easily in the body, disintegrate in a period of time less than 5 minutes and are quite stable in the case that formulations comprise a combination of disintegrant composed of at least two different disintegrants wherein ⁇ the amount of the first disintegrant is more than 5% and
- the amount of the second disintegrant is less than 10% in proportion to total formulation amount.
- the present invention relates to pharmaceutical tablet formulations comprising cefpodoxime proxetil and clavulanic acid combination characterized in that said formulation comprises a combination of disintegrant composed of at least two different disintegrants wherein
- tablet formulations comprising cefpodoksime proxetil and clavulanic acid are characterized in that the amount of the first disintegrant is in the range of 5-20%, preferably in the range of 6-15% in proportion to total formulation weight.
- tablet formulations comprising cefpodoxime proxetil and clavulanic acid are characterized in that the amount of the second disintegrant is in the range of 1 -10%, preferably in the range of 3-8% in proportion to total formulation weight.
- the stability problems observed in cefpodoxime proxetil and clavulanic acid formulations decrease solubility of the drug in the body hence totality of the drug is not absorbed. This case leads to low bioavailability of the drug and low efficiency of the treatment.
- the ratio of the first disintegrant to second disintegrant used in said formulations should be optimized. Accordingly, during the studies conducted for solving this problem, the inventors have found that if the ratio of the first disintegrant to the second disintegrant in the formulations prepared in accordance with the present invention is in the range of 5: 1 to 1 :5, preferably in the range of 4: 1 to 1 :3 by weight, more stabile and more soluble dosage forms in the body are obtained.
- the ratio of the first disintegrant to the second disintegrant is in the range of 5: 1 to 1 :5, preferably in the range of 4: 1 to 1 :3 by weight.
- the first disintegrant can be selected from a group comprising croscarmellose calcium, carboxymethyl cellulose sodium, microcrystalline cellulose, croscarmellose sodium, hydroxypropyl cellulose, methylcellulose and/or combinations thereof.
- the first disintegrant is croscarmellose calcium.
- the second disintegrant is selected form group comprising carboxymethyl cellulose sodium, microcrystalline cellulose, hydroxypropyl cellulose, methylcellulose, starch and/or combinations thereof.
- the second disintegrant is starch.
- the ratio of croscarmellose calcium to starch can be in the range of 5: 1 to 1 :5, preferably in the range of 4: 1 to 1 :3 by weight.
- cefpodoxime proxetil formulations Another problem observed in cefpodoxime proxetil formulations is the formation of aggregates during the preparation of the tablet form. If these aggregates are not eliminated, they prevent the formation of a homogenous mixture and destroy the uniform distribution of the active agent in the formulation. Studies conducted for solving said problem showed that not only the ratio of the disintegrants to each other but also the amount of cefpodoxime proxetil in proportion to the amount of disintegrant combination plays an important role in preparation of said formulations.
- the inventors have found out that if the ratio of cefpodoxime proxetil to the disintegrant combination is in the range of 6: 1 to 1 :6, preferably 3:1 to 1 :3 by weight, no agglomeration is observed and the uniform distribution of the active agent is can be provided.
- the ratio of cefpodoxime proxetil to the disintegrant combination is in the range of 6: 1 to 1 :6, preferably 3:1 to 1 :3 by weight.
- Clavulanic acid comprised in the pharmaceutical formulations of the present invention can be in the form of its pharmaceutically acceptable salts, hydrates, solvates, esters, enantiomers, racemates, organic salts, inorganic salts and free base form or combinations thereof in respect to its chemical structure; in crystalline, amorphous form or combinations thereof in respect to its polymorphic structure.
- clavulanic acid used as second active agent is in the potassium salt form.
