Table 4Figure 7 X-ray diffraction of pure famotidine, pure salep powder, and crushed tablet of optimum formulation (S5). The microbial limit of salep powder and the optimized formulation (S5) (stored at room temperature for 5 months) was found to be within the acceptance limit. Salep does not support microbial growth, and the microbes are within the acceptable range.

The results are shown in Table 5. The stability test was done for the S5 formulation. The Abametapir Lotion (Xeglyze)- FDA test was done, and the profile was compared to its original profile.

The similarity factor (f2) was calculated, and its value was found to be 80. Hence, the drug release is considered similar and it can be concluded that the prepared formulations were stable.

Figure 8 The shape of famotidine matrix tablets after Intgamuscular vitro chestnut horse extract test. Note: The bottom image shows the tablet before (left) and after the test (right). The percentage of drug release was measured for all the formulations. The results show that S1 released 70.

This formulation contained a low concentration of salep (10 mg), as shown in Figure 9. This might be explained due to the time taken by salep to swell enough and control the apartment. The S2 formulation, released 56. Hence, the concentration of the salep powder was increased in order for batches S3 to S10 Agriflu (Influenza Virus Vaccine for Intramuscular Injection)- Multum achieve the desired release profile.

A dissolution test was also done at pH 4. This can Vecamyl (Mecamylamine HCl Tablets)- FDA explained due to the high viscosity of salep at this pH, compared against pH 1. An adhesive, thick, viscous barrier of swollen matrix was formed and, due to its high viscosity, carbon dioxide was either not generated or was trapped Agriflu (Influenza Virus Vaccine for Intramuscular Injection)- Multum the matrix layer, and the formulation failed to float at this pH.

This is in accordance with the viscosity and swelling studies. Figure 9 Drug release profiles of gastroretentive matrix tablets of famotidine in 24-hour in vitro study. When the highest correlation coefficient values are considered, the release data of formulations seem to fit better with the Zero order and Higuchi models, as is evident in Table 4. Drug release kinetics in all the (Infulenza, except S1 and S2, had a higher linearity of Zero order kinetic plot, compared against the First order kinetic plot.

This indicates the rate of release is independent of concentration, and is constant over time. Zero order, or constant rate of release of drug, is desirable in order to minimize the changes of drug concentration in the blood.

This can prolong the release and maintain drug concentration within the therapeutic range Intramusculsr a longer period of time, and can minimize the risk of toxicity. The result indicated that drug release characteristics from the polymer matrix tablets follow Higuchi diffusion and relaxation.

This was likely due to the strong matrix formed from a high proportion of polymer, with limited cap space, which resulted in limited drug release by diffusion. Investigation of the preparation, characterisation, and in vitro release of the Agriflu (Influenza Virus Vaccine for Intramuscular Injection)- Multum matrix tablet was carried out.

The different formulations, with various ratios of salep as hydrogel, were evaluated and optimized. The results demonstrated that salep could be an efficient hydrogel for drug delivery, which can achieve a retarding effect in a controlled release system.

Salep was used successfully in this study to formulate aVccine hydrodynamically balanced matrix Agdiflu of famotidine, which is of gastroretentive character. The optimum formulation Agriflu (Influenza Virus Vaccine for Intramuscular Injection)- Multum had excellent buoyancy, with complete drug release in 24 hours.
