The pre-compression parameters of all the formulations were depicted in the Table 2. The angle of repose, bulk density, tapped density, Carr’s index and hausner’s ratio shows good flowability in almost all the formulations resulting suitable for the preparation of Fast dissolving tablets. The prepared tablets were evaluated for different parameters and results were depicted in Table 1. Thickness of the formulations FFGK1 to FFGK5 varied from 2.73±0.24 to 2.96±0.85 mm while of formulations FOB1 to FOB5 showed from 2.83±0.55 to 3.3±0.98 mm respectively. The hardness was uniformly maintained and it was found to be within 2.7±0.32 to 3.3±0.65 kg/cm 2 . Percent friability was less than 1% in the entire formulations and the values obtained lies within 0.29±0.12 to 0.83±0.09 and found within the range only. The percentage weight variation for all the formulations are tabulated in Table 2. All the tablets passed weight variation test as the % weight variation was within the pharmacopoeial limits of±7.5%. The percentage drug content of all the tablets was found to be between 99.11±0.54 to 101.31±0.25, which was within the acceptable limits. Tablets from each batch show immediate disintegration. Disintegration time decreases with increase in concentration of the disintegrants. Disintegration time was given in Table 2. The rapid disintegration % drug release 120 100 80 60 40 20 0 0 5 10 15 20 time (mins) FFGK5 FOB5 Figure 6: Dissolution profile of optimized formulations. was seen in the formulation FFGK5 containing Fenugreek seed mucilage as superdisintegrating agent. This is due to the rapid uptake of water from the medium, swelling and burst effect. As in the Ocimum basilicum gum FOB5 also same. As the concentration increases the disintegration time decreases profoundly. The wetting time was rapid in all the formulations. wetting is closely related to inner structure of tablets. This may be due to ability of swelling and also capacity of absorption of water. The results were depicted in the Table 2. The water absorption ratio that is the uptaking of water was very fast and the ratio was found higher. Dissolution profile of the formulations FFGK1, FFGK2, FFGK3, FFGK4, FFGK5 and formulations FOB1, FOB 2, FOB 3, FOB 4, and FOB 5 is shown in Figure 4, 5. As the concentration of the polymer increased there was decrease in the disintegration time and increase in dissolution of drug. 90% of the drug was released from the all the formulations within 15 minutes. From drug release it was observed that increase in concentration of superdisintegrant increases the drug release. Therefore formulation FFGK5 and FOB5 was selected as the optimized formulation as it showed good release, good wetting property, and good precompression and good post compression results. 248
From the values obtained, it is proved that all the formulations FFGK1 to FFGK5 and FOB1 to FOB5 dissolution (release) of the drugs follows first order. The optimized formulations FFGK5 and FOB5 were kept for accelerated stability and monitored for appearance, hardness, friability, drug content, in vitro dispersion time, wetting time and dissolution profile study and found to stable for all the different parameters [Figure 6]. CONCLUSION In the present study the superdisintegrant property of Fenugreek seed mucilage and Ocimum basilicum gum has been explored. Extensive swelling, porosity and wicking action of the natural material in the fast dissolving tablet formulation were found to be contributing its superdisintegrant action. The tablets disintegrated much faster and consistently when Fenugreek seed mucilage and Ocimum basilicum gum was used as superdisintegrant compared to synthetic superdisintegrants. Fenugreek seed mucilage and Ocimum basilicum gum could be used for different applications in tablet dosage forms and may be explored as high functionality excipients for future applications.
