The kinetics of water transport into tablets, and how it can be controlled by the formulation as well as the tablet microstructure, are of central importance in order to design and control the dissolution and drug release process, especially for immediate release tablets. This research employed terahertz pulsed imaging to measure the process of water penetrating through tablets using a flow cell. Tablets were prepared over a range of porosity between 10% to 20%. The formulations consist of two drugs (MK-8408: ruzasvir as a spray dried intermediate, and MK-3682: uprifosbuvir as a crystalline drug substance) and NaCl (0% to 20%) at varying levels of concentrations as well as other excipients. A power-law model is found to fit the liquid penetration exceptionally well (average R2>0.995). For each formulation, the rate of water penetration, extent of swelling and the USP dissolution rate were compared. A factorial analysis then revealed that the tablet porosity was the dominating factor for both liquid penetration and dissolution. NaCl more significantly influenced liquid penetration due to osmotic driving force as well as gelling suppression, but there appears to be little difference when NaCl loading in the formulation increases from 5% to 10%. The level of spray dried intermediate was observed to further limit the release of API in dissolution.

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.

Fexofenadine Hcl

Fexofenadine HCl immediate release tablets were designed to increase the dissolution rate by using superdisintegrants. Different formulations of Fexofenadine HCl were prepared by direct compression method. These formulations were evaluated for hardness, thickness, friability, weight variation, disintegration time, and in vitro dissolution study. The drug release from the formulations were studied according to USP specification (USP paddle method at 50 rpm for 60 minutes) maintaining the temperature to 37°C. Sodium starch glycolate, cross carmellose sodium, crospovidone (kollidon CL), ludiflash and xanthan gum were used in 3%, 6% and 8% concentrations as superdisintegrants. Thus, the ratio of superdisintegrants was changed whereas all the other excipients as well as the active drug (Fexofenadine HCl) remained same in every formulation. Here, 0.001N HCl was used as dissolution medium according to USP and absorbances were determined by using UV spectrophotometer at 217 nm. The F-3 and F-6 formulation prepared by 8% of Sodium starch glycolate and 8% of Cross carmellose sodium showed 99.99% drug release within 30 minutes and 45 minutes, respectively. The disintegration times of F-3 and F-6 formulation were within 9 seconds. The interactions between drug and excipients were characterized by FTIR spectroscopic study.

Divalproex sodium is considered as the most important antiepileptic drug and widely used for treatment of epilepsy and bi-polar disorders and prophylaxis of migraine. The present work has been done to formulate bi-layered tablet of Divalproex sodium containing immediate release layer and sustained release layer. The FTIR study revealed that there was no interaction between drug and polymer and combination. Both layers were prepared by wet granulation technique as poor flow property exhibited by pure drug. The immediate release layer was formulated by using superdisintegrants and evaluated for physical parameters, disintegration time and in vitro drug release. The optimized immediate release layer (IF6) with highest in vitro release of 98.11 was selected for bi-layered tablet formulation. HPMC K4M and HPMC K100M polymer were used to retard the drug release from sustained release layer in different proportion and combination and evaluated for physical parameter along with in vitro drug release studies. The optimized sustained release layer (SF8) which extends the Divalproex sodium release more than 18 hrs was selected. Finally, bi-layered tablets were prepared by double compression of selected sustained release layer and immediate release layer of Divalproex sodium. The tablets were evaluated for hardness, thickness, weight variation, friability, drug content uniformity and in vitro drug release. All the physical parameters were in acceptable limit of pharmacopeial specification. The stability studies, shown the bi-layer tablet was stable at 40oC / 75% RH for a period of 3 months.

Film Forming

In order to improve the solubility properties of BCS class II drug itraconazole, fast dissolving oral polymeric film formulations based on itraconazole nanocrystals were produced. Drug nanocrystals were manufactured by the wet pearl milling technique. In polymeric film formulations, hydroxypropyl methyl cellulose (HPMC) was used as a film forming polymer, and glycerin was used as a plasticizer. For nanocrystal suspensions and film formulations, thorough physicochemical characterization was performed, including particle sizing and size deviation, film appearance, weight variation, thickness, folding endurance, drug content uniformity, disintegration time, and dissolution profile. After milling, the nanoparticles were 369 nm in size with a PI value of 0.20. Nanoparticles were stable and after redispersion from film formulations, the particle size remained almost the same (330 nm and PI 0.16). The produced films were flexible, homogeneous, fast disintegrating, and drug release rate from both the nanosuspension and film formulations showed immediate release behavior. Based on the study, the film casting method for production of itraconazole nanocrystal based immediate release formulations is a good option for improved solubility.
