The purpose of this study was to investigate the efficiency of superdisintegrants: sodium starch glycolate, croscarmellose sodium and crospovidone in promoting tablet disintegration and drug dissolution of Topiramate immediate release tablets. The efficiency of superdisintegrants was tested, by considering four concentrations, viz., like 2%, 3%, 4% and 5% in the formulations. The dissolution was carried out in USP apparatus II at 50 rpm with distilled water as a dissolution medium. The dissolution rate of the model drug topiramate was found highly dependent on the tablet disintegration, on the particle size of the superdisintegrant, on the solubility of the drug and also on the type of superdisintegrant in the dissolution medium. There was no effect of the diluent (Lactose monohydrate) on the disintegration of different concentrations of superdisintegrants. These results suggest that, as determined by the f2 metric (similarity factor), the dissolution profile of the formulation containing 4% sodium starch glycolate and lactose monohydrate as a diluent was similar to that of a marketed product.

AbstractDissolution testing plays many important roles throughout the pharmaceutical industry, from the research and development of drug products to the control and evaluation of drug quality. However, it is a challenging task to perform both high-efficient separation and high-temporal detection to achieve accurate dissolution profile of each active ingredient dissolved from a drug tablet. In our study, we report a novel non-manual-operation method for performing the automatic dissolution testing of drug tablets, by combining a program-controlled sequential analysis and high-speed capillary electrophoresis for efficient separation of active ingredients. The feasibility of the method for dissolution testing of real drug tablets as well as the performance of the proposed system has been demonstrated. The accuracy of drug dissolution testing is ensured by the excellent repeatability of the sequential analysis, as well as the similarity of the evaluation of dissolution testing. Our study show that the proposed method is capable to achieve simultaneous dissolution testing of multiple ingredients, and the matrix interferences can be avoided. Therefore it is of potential valuable applications in various fields of pharmaceutical research and drug regulation.

Purpose. To evaluate the influence of co-administered vehicles on in vitro dissolution in simulated gastric fluid of crushed immediate release tablets as an indicator for potential drug bioavailability compromise. Methods. Release and dissolution of crushed amlodipine, atenolol, carbamazepine and warfarin tablets were tested with six foods and drinks that are frequently used in the clinical setting as mixers for crushed medications (water, orange juice, honey, yoghurt, strawberry jam and water thickened with Easythick powder) in comparison to whole tablets. Five commercial thickening agents (Easythick Advanced, Janbak F, Karicare, Nutilis, Viscaid) at three thickness levels were tested for their effect on the dissolution of crushed atenolol tablets. Results. Atenolol dissolution was unaffected by mixing crushed tablets with thin fluids or food mixers in comparison to whole tablets or crushed tablets in water, but amlodipine was delayed by mixing with jam. Mixing crushed warfarin and carbamazepine tablets with honey, jam or yoghurt caused them to resemble the slow dissolution of whole tablets rather than the faster dissolution of crushed tablets in water or orange juice. Crushing and mixing any of the four medications with thickened water caused a significant delay in dissolution. When tested with atenolol, all types of thickening agents at the greatest thickness significantly restricted dissolution, and products that are primarily based on xanthan gum also delayed dissolution at the intermediate thickness level. Conclusions. Dissolution testing, while simplistic, is a widely used and accepted method for comparing drug release from different formulations as an indicator for in vivo bioavailability. Thickened fluids have the potential to retard drug dissolution when used at the thickest levels. These findings highlight potential clinical implications of the addition of these agents to medications for the purpose of dose delivery and indicate that further investigation of thickened fluids and their potential to influence therapeutic outcomes is warranted. This article is open to POST-PUBLICATION REVIEW.

The study aimed to develop and evaluate an immediate-release tablet dosage form of Linagliptin. Different concentrations (ranges 5-10%) of super-disintegrants, Croscarmellose sodium (CCS), and Sodium starch glycolate (SSG) were used to prepare nine tablet dosage forms (F1 to F9) through the direct compression method. The compatibility of the formulations was evaluated by FTIR to reveal any possible drug-excipient interactions and it was proved to be compatible with all formulations. Precompression (bulk density, tapped density, Carr’s index, Hausner’s ratio, and angle of repose) and post-compression parameters (weight variation, hardness, thickness, and friability) were analyzed for all tablets and the results were found satisfactory as well as within limits as per USP guidelines. All the formulated batches (F1 to F9) exhibited disintegration of tablets within 2 minutes, where formulation F9 represented the lowest disintegration time (51±3 sec) which was also found significantly better than the marketed product (310±5 sec). In terms of drug dissolution, 90% of drug release was observed for all nine formulations within 45 minutes and formulation F9 (5% CCS and 5% SSG) illustrated the rapid and highest dissolution rate compared to the marketed one’s, 100% drug release at 20 minutes and 91.77 % drug release at 30 minutes successively. The respective data sets of drug release were mathematically fitted to several kinetic models and for all formulations, drug release pattern obeyed first-order kinetics amongst those, formulation F2 (r2= 0.98), F4 (r2= 0.99), F5 (r2= 0.98), and F9 (r2= 0.97) were found to be best fitted in this kinetic norm. Based on disintegration time and dissolution data comparison to a brand leader market product, F9 was experienced as the best formulation. Furthermore, it was observed that if SSG and CCS were combined, then these two parameters were more improved compared to their separate uses. Thus, incorporation of the optimum amount of super-disintegrants in a formulation showed rapid swelling, faster disintegration as well as ease of dissolution of tablet dosage forms.

The rationale of this investigation is to design an immediate release oral dosage of Sumatriptan succinate by using microcrystalline cellulose as filler, camphor and menthol as subliming agents by direct compression method .The basic objective of this dissertation is to develop an orodispersible tablet of sumatriptan succinate used in anti-migraine with an aim of reduces the lag time and providing faster onset of action to relief the acute migraine effect immediately. Disintegrates and disperses in oral cavity within 30 seconds without the need of drinking water. Has pleasant mouth feel and there is no after taste or grittiness. Successfully discriminates the ability of three superdisintegrants to promote drug dissolution and proposes a model formulation for disintegrants performance testing and quality control purposes. The formulation F6 containing 8% of CCS and 10% of menthol showed disintegration time of 18seconds after drying. Menthol as subliming agent was found to be most effective of all other subliming agents as it had showed drastic effect on the drug release.

The aims of this study were to develop a predictive immediate release tablet formulation system for soluble drugs. Ranitidine hydrochloride, silicifiedmicrocrystallinecellulose (SMCC), polyplasdone XL and hydroxyprophylmethylcellulose (HPMC) E6 were evaluated for powder properties. The effects of binder (HPMC E6) and disintegrant (Polyplasdone XL) were investigated. A 32 factorial design was applied to optimize the drug release profile. The amount of binder and disintegrant were selected as independent variables. The times required for 50% (t50) and 80% (t80) drug dissolution and similarity factor (f2) were chosen as dependent variables. The results of factorial design indicated that a high amount of binder and low amount of disintegrate favored the preparation of drug release. The difference (f1) and similarity (f2) factors were used to measure the relative error and the closeness (similarity) between the factorial design batches and brand name drugs. No significant difference was observed between the brand drug and ranitidine batches F1, F2, F5, F6 and F9. Ranitidine batch F2 yielded the highest value of f2(71%)and the lowest of f1(10%). This research indicates that the proper amount of binder and disintegrant can produce drug dissolution profiles comparable to their brands.

Purpose : The aim of this study was to evaluate the influence of the geometric shape on the dissolution rate of the domperidone, a drug model for immediate release dosage form. In this regard, a lack of sufficient information about the effective dissolution rate of the drugs regarding their shapes has made this issue an interesting subject for researchers. Methods: For this purpose, three tablet shapes, namely flat and biconvex both in a round and oblong shapes, with different four sizes were modelled for the preparation of domperidone tablet. In vitro dissolution test was accomplished using a USP dissolution apparatus II. The drug dissolution rate was assessed by calculating various dissolution parameters; e.g., dissolution efficiency (DE), mean dissolution rate (MDR), mean dissolution time (MDT), and difference and similarity factors (f1 and f2 ). Results: Regarding the disintegration time, the larger tablets showed a faster disintegration time. When the size of the tablets was smaller, the amount of released drug was significantly decreased. In addition, #9 tablets with a flat or biconvex geometry had obvious effects on the DE values. Generally, biconvex tablets had higher DE percentage than the flat tablets. Conclusion: Noticeable differences in dissolution parameters by considering the different geometric shapes play an important role in the drug release kinetics which makes a significant effect on quick onset of action in oral administration.
