ABSTRACT
Objective: In the present investigation, fast dissolving tablets of cefpodoxime proxetil were formulated using superdisintegrants to impart fast disintegration.
Methods: In the current study, 12 formulations of fast dissolving tablets of cefpodoxime proxetil were formulated using two different approaches viz., direct compression and sublimation. Three different superdisintegrants viz., croscarmellose sodium, sodium starch glycolate, and crospovidone were used in a different concentration in all the respective formulations. The final powder blend was subjected for the pre-compression evaluation and all the formulations were evaluated for post-compression parameters. Stability studies were also evaluated for the best formulations as per ICH guidelines. Finally, results were statistically analyzed by the application of one way ANOVA test and t-test.
Results: Among all the formulations of different approaches, formulation cefpodoxime proxetil 4 (CP4) containing 6% crospovidone as a super disintegrant was showed the best results. In vitro dissolution data revealed that formulation CP4 prepared by direct compression method showed 99.387±0.270% drug release within 15 min whereas the percentage release by formulation prepared by using sublimation showed 83.927±0.735% release. The optimized formulation was further subjected to comparative in vitro study with two marketed formulation of different brands.
Conclusion: All the data of all formulations is shows that direct compression approach is the best approach for developing the fast dissolving tablets to enhance the onset of action and bioavailability.

The most suitable and widely acceptable delivery system for drug administration is the oral drug delivery system because of its self-administration; compactness and easy manufacturing [1]. More than 75% of drugs are given in orally. Oral drug delivery system is becoming important day by day due to its fine characteristics; no invasion, no pain, easy to handle and patient compliance [2]. Due to its great importance, it also left some of the drawbacks, in which the major drawback is dysphagia [3]. Pediatrics and geriatrics patients suffer a lot from the dysphagia (difficulty in swallowing) which leads to poor patient compliance [4]. Therefore, to improvise such issues novel drug delivery system is come in existence called fast dissolving tablets (FDTs).
The demands of the development of FDTs are increased enormously as it has a great impact on patient compliance. Fast disintegrating tablets (FDTs) are gaining more popularity because drug gets dissolved or easily disintegrated in the mouth within a sec without the need of water [5].
Nowadays, fast dissolving tablets are very important to increase the bioavailability of the drug and onset of action in comparison with conventional tablets which have low bioavailability, low solubility and the large onset of action. Basic considerations of FDTs are to improve the aqueous solubility, permeability, mechanical strength etc. therefore drugs which have low aqueous solubility and low permeability (Class III drugs of BCS System) are considered important [6, 7].
Cefpodoxime proxetil (CP) is a broad spectrum third-generation cephalosporin, which shows effective antibacterial activity against both gram-positive and gram-negative bacteria. Cefpodoxime proxetil having the low aqueous solubility and also having the low oral bioavailability up to 50% that may have a negative impact on its sub-therapeutic plasma drug levels leading to therapeutic failure [8, 9].
Consequently, to improve the aqueous solubility and bioavailability of cefpodoxime proxetil, FDTs of cefpodoxime proxetil will be in consideration. Therefore, it is hypothesized that fast dissolving tablets of cefpodoxime proxetil will provide enhanced bioavailability and better patient compliance.
In the present study fast dissolving tablets of cefpodoxime proxetil was achieved by using two different methods viz., direct compression and sublimation method in-order to improve the disintegration time and dissolution rate which may further improve bioavailability and faster onset of action of drug.
Cefpodoxime proxetil was obtained as gift sample from INOVA CAPTAB UNIT-II Baddi, HP, India, sodium starch glycolate, microcrystalline cellulose, croscarmellose sodium were obtained as a gift sample from Maple Biotech Pvt. Ltd. Pune, India. All other ingredients and chemicals used were of analytical grade.
Preformulation studies
All the preformulation parameters were carried out effectively.
Differential scanning calorimetry
Differential scanning calorimetry (DSC) analysis was performed using Perkin-Elmer Series 7 DSC on 2 to 8 mg samples pure cefpodoxime proxetil [10].
Compatibility studies
A perfectly dried sample of the pure drug (with excipients) was mixed with dried potassium bromide (KBr) powder. The mixture was then subjected to KBr press to obtain the mixture pellet. The pressure for preparing the palate was between 10000 to 12000 psi. The prepared drug pellet was scanned between 4000 to 400 cm-1 at a resolution of 4 cm-1. The spectrum was recorded and interpreted for the confirmation of the drug purity [11, 12].
Determination of absorption maxima (λmax)
Known concentrations of cefpodoxime proxetil were prepared in different solvents viz., glycine buffer of pH 3.0. Concentrations were then scanned in UV spectrum mode in the range of 400-200 nm against similarly treated blank [13].
Calibration curve
Accurately weighed, 100 mg of cefpodoxime proxetil was dissolved in 50 ml of glycine buffer pH 3.0 in 100 ml of the pre-calibrated volumetric flask. The solution was shaken for few minutes until a clear solution was obtained and volume was makeup with methanol which gives a standard solution of 1000 µg/ml. Different dilutions of known concentration were prepared from the standard solution ranging between 20-32 µg/ml. Absorption was measured at 257 nm using glycine buffer pH 3.0 as blank.
Determination of qualitative solubility of cefpodoxime proxetil in different solvents
The solubility of cefpodoxime proxetil was determined in various solvents viz., methanol, water, phosphate buffer pH 6.8, and glycine buffer pH 3.0, 0.1N HCl. Solubility was done by Higuchi conner method [13]. Active drug was added in different solvents in 10 ml of the volumetric flask. All volumetric flasks were placed in digital water bath shaker for 72 h continuous shaking at ambient temperature. After that, the solution was filtered using Whatman filter paper (No. 42). The filtrate solution was then further diluted and absorption was measured by UV-VIS spectrophotometer against similarly treated blank.
Preparation of fast dissolving tablets (FDTs)
FDTs were prepared by two different techniques viz; direct compression and sublimation technique using different superdisintegrants at a different level of concentrations. The entire ingredients were weighed carefully and were sieved through sieve no. 60 [14, 15].
The blend was mixed thoroughly and was directly subjected to compression into 200 mg tablets using tablet punching machine. Then compressed tablets of the sublimation technique were allowed to sublime by placing them in a hot air oven for 6 h at a temperature of 60±1 °C [16, 17]. All the prepared formulations were then subjected for further evaluations.

Evaluation of tablets
Pre-compression evaluation
Pre-compression method of powder blend was evaluated effectively which includes bulk density, tapped density, hauser's ratio, carr’s index and angle of repose (θ) [18-21].
Post-compression evaluation
All the prepared formulations were subjected to post-compression evaluations.
Hardness
The hardness of the tablets was evaluated by monsanto hardness tester. 6 tablets of each batch were taken randomly for hardness and average hardness was calculated [22].
Thickness
20 tablets of each batch were selected randomly and the thickness was determined by digital vernier calliper. Average of the thickness was then calculated [23].
Uniformity of the weights
Randomly, 20 tablets were taken from each batch and accurately weighed individually by digital weighing balance and the average weight of each batches tablets were calculated. Weight variation of the individual tablet was calculated and compared with the standard limits as per Indian Pharmacopoeia (IP) [24].
Friability
Friability of the tablets was determined by using the friability test apparatus. Accurately pre-weighed 20 tablets were taken and placed onto the digital friabilator [25]. The friabilator was rotated to 100 revolutions for 4 min. The loss of weight of the tablets was measured and friability was calculated.
Uniformity of the drug content
Six tablets of each batch were taken and crushed to form a fine powder and powder was weighed equivalent to 50 mg of the drug. A weighed amount of powder was dissolved in small amount glycine buffer pH 3.0 which was freshly prepared into the 100 ml volumetric flask. Make up the volume after sonication was done for 25 min. The mixture was then filtered by using whatman filter paper (No. 42). 1 ml of the solution was taken and make up the volume up to the mark (100 ml). The final solution was analyzed in UV-VIS spectrophotometer at 257 nm wavelength against similarly treated blank [26, 27].
In vitro disintegration time
Six tablets were taken from all formulations and maintaining the water temperature at 37.0±0.5 °C. Time taken for complete the disintegration of tablets was recorded by stopwatch. For accuracy, an average of six tablets was taken [28].
Wetting time
10 cm diameter five tissue papers were placed in a dry petri plate. 2 ml of amaranth dye solution was added to the petri plate along with 10 ml of simulated saliva solution. Tablets were put on the tissue paper and the time for complete wetting was measured by a stopwatch. Average three tablets of each batch were measured [29].
Water absorption ratio
10 cm diameter five tissue papers were placed in a dry Petri plate. 2 ml of amaranth dye solution was added to the Petri plate along with 10 ml of simulated saliva solution. Tablets which were pre-weighed were put on the paper. When the tablets were wet in all sides, then tablets were re-weighed and water absorption ratio was calculated [30].
In vitro dissolution studies
USP Type-II (paddle type) dissolution apparatus were used for in vitro dissolution. Three tablets of each batch were used for determination of dissolution studies. Glycine buffer pH 3.0 (900 ml) was used as dissolution media which was maintained at 37.0±0.5 °C and speed of the paddle were adjusted at 75 rpm. 10 ml sample was withdrawn at the different time of interval and diluted adequately. All samples were analyzed at 257 nm wavelength in UV-VIS spectrophotometer using similarly treated blank. From the raw dissolution data, the total amount of drug release profile was calculated at a different interval of time [31]. The kinetic studies for all formulations were also done. Further, the optimized formulation was subjected to comparative in vitro studies with the marketed formulation of two different brands.
Statistical analysis
Statistical analysis of selected formulation and marketed formulations was done using graph pad prism 7.0 software. Statistical analysis is important to check the formulation that the selected formulation is significant or not significant [32].
Short-term stability studies of optimized batch
In the present study, selected batch in aluminum foil pack was placed in a stability chamber for stability studies at 40.0±2.0 °C/ 75.0±5.0 % RH for 3 mo. Samples were collected after 3 mo interval and evaluated for physical appearance, disintegration time wetting time, drug content and in vitro dissolution [33].
Pre-formulation parameters
Cefpodoxime proxetil was observed for organoleptic properties like physical appearance, odor, and melting point. The drug was identified with the help of UV and FTIR and exhibited absorption maxima at 257 nm when methanol was used as a solvent as mentioned in the literature (fig. 1). The Beer’s Lambert range was found to be 24-32µg/ml and the standard curve has shown R2 value of 0.996 with the euqtion of linearity as y=0.11x+0.002 as shown in fig. 2.
Differential scanning calorimeter shows endothermic fusion peak at 110.45 °C, which was corresponding to the melting point of cefpodoxime proxetil (fig. 3).

Pre-compression evaluations
All formulations were evaluated effectively for pre-compression evaluations. Data is represented in table 4.
Post-compression evaluations
Post-compression evaluations of all formulations were carried out successfully and data are tabulated table 5 and table 6 respectively [27].
In vitro dissolution studies were conducted for all the formulations via USP type-II dissolution apparatus, using glycine buffer pH 3.0 as a dissolution medium. It was observed that more than 90 % drug was released within 15 min in direct compression method formulations (CP1-CP6). Tablets formulated by the sublimation method showed more than 80 % of the drug release within 15 min. Formulation CP4 that containing 6 % of crospovidone revealed maximum drug release profile up to 99.387±0.270 % within 15 min, whereas formulation CP12 showed 83.927±0.735 % drug release (fig. 4).

Fig. 4: Comparative in vitro drug release profile of all formulations (CP1-CP12)
Hence, the release profile revealed that tablets containing super disintegrants were better in term of drug release, further crospovidone resulting in faster drug release 99.387±0.270 % within 15 min, when compared with other super disintegrants [28]. The Formulation CP4 prepared by direct compression method also showed better dissolution when compared with formulations prepared by sublimation. Therefore, CP4 formulation was optimized as best formulation and further subjected for comparative in vitro drug release with two marketed formulation of different brands. The marketed formulations showed 88.907±0.566 % and 92.627±0.719 % drug release in 15 min (Figure5). The percent drug release is tabulated in table 10 and fig. 5 respectively.

The in vitro release data were subjected to various mathematical release models viz., zero order, first order, Higuchi and Pappas and best-fit model were decided by the highest R2 value. On the basis of maximum regression value, Higuchi Model for drug release kinetics was found to be the best fit model for most of the formulations (table 7).

Statistical analysis of selected formulation and marketed formulations were calculated by graph pad prism 7.0. Applying, one way ANOVA, it was found that there is no significant difference in all twelve formulations. Using t-test for comparison of the selected formulation with marketed formulations, formulation CP4 and MKT1 showed that there was no significant difference.
Thus, above studies indicate that formulation CP4, MKT1, and MKT2 is having an almost similar profile, but CP4 will provide improved onset of action and bioavailability as indicated by its dissolution rate.
Short-term stability study of the optimized formulation
A sample withdrew after three months shown no more drastic change in in vitro drug release profile. All the data showed the good similarity of dissolution profile before and after stability studies (table 8). Results of the stability study had shown no remarkable change in the release profile of the cefpodoxime proxetil FDTs after the stability. Stability study of selected formulation CP4 was found to be stable and complies with pharmacopeial standards.

Fast dissolving tablets were prepared in two different approaches to direct compression and sublimation. Pre-formulations parameters like the physical characterization of the drug were evaluated. All the formulations were passed the pre-compression and post-compression parameters. Formulation CP4 that contained 6 % of crospovidone showed the fastest drug release of 99.387±0.270 % within 15 min which was the optimized formulation. Thus, it was concluded that fast dissolving tablets of cefpodoxime proxetil can be successfully prepared using direct compression technique and it will enhance the drug dissolution which will further increase absorption and bioavailability of the drug.
