Comparative Study of Various Polymeric Superdisintegrants on the Design and Evaluation of Novel Antihypertensive Orodispersible Tablets

Abstract

Superdisintegrants are major participants in orodispersible tablets (ODTs) to accord fast disintegration. A myriad of natural and synthetic disintegrants have been utilized. In present work, antihypertensive ODTs of atenolol and atorvastatin calcium were prepared in two groups based on a combination of superdisintegrants, i.e., F1-F15 (sodium starch glycolate and pregelatinized starch) and F16-F30 (croscarmellose sodium and Kyron T 134 ). The direct compression method was adapted along with the effervescence and sublimation approach. The effect of manufacturing process, concentration, and type of superdisintegrants on characteristics of ODTs was observed. Rheological and compatibility studies such as Fourier transform infrared spectroscopy and differential scanning calorimetry were performed for drug and other markers. Scanning electron microscopy proved the presence of pores on the tablet surface. Postcompression parameters such as tablet hardness, thickness, diameter, weight variation, friability, disintegration time, dissolution studies, wetting time, wetting volume, water absorption ratio, modified disintegration, uniformity of contents, and stability studies were carried out. Finally, results were statistically evaluated by the application of one-way analysis of variance test. Based on parameters formulation, F23 designed by the sublimation technique declared best one among all. C 2015 Wiley Periodicals, Inc.

Development of Meloxicam Oral Lyophilisates: Role of Thermal Analysis and Complementary Techniques

“…CCSshowed moisture release also reported by Sarfraz et al[39], followed by melting and decomposition. SA presented moisture loss at 87°C and decomposition at 240°C, as Soares et al have previously obtained[42].…”

Compatibility Study Between Magnesium Orotate and Various Excipients in Their Physical Mixtures

“…Except the MO-T mixture, the FTIR spectra (Figure 7) of the binary mixtures contain the individual fingerprints of the MO and excipient, without any additional new absorption bands. The FT-IR spectrum of CC (Figure 7a) is similar to that reported by Sarfraz et al [29]. S (Figure 7b) presents a wide band at 3417 cm -1 attributed to the stretching vibration of the O-H bond and a band at 2918 cm -1 attributed to the C-H bond.…”

Discrimination of commercial ibuprofen tablets by using a button sample holder and mid-infrared spectroscopy

“…The A-IBP coating spectrum exhibits a broad OH stretching vibration band that is likely due to excipients in the formulation, including hydroxypropyl methylcellulose [24][25][26] and sodium croscarmellose. [27][28][29] The shoulder at 3560 cm À1 may indicate the presence of polysorbate 80. [30][31][32] The E-IBP coating spectrum contains a sharp band near 1700 cm À1 characteristic of the C]O stretching vibration of ibuprofen that is not present in the A-IBP spectrum.…”
