Aims: This research was done to study the effects of types and concentrations of lubricants on the dissolution and disintegration profile of metronidazole tablets formulated using Sida acuta gum as a binder. Methodology: Sida acuta gum (SAG) was extracted from powdered dried leaves of Sida acuta. Metronidazole granules were produced by wet granulation technique using different concentrations (1 and 2%) of SAG as a binder and mixed with different concentrations (0.5, 1.0, and 1.5%) of magnesium stearate (MS) or sodium lauryl sulphate (SLS) as a lubricant. The granules/lubricant -mix was compressed into tablets and evaluated for hardness, weight uniformity, drug content, disintegration time, friability and in vitro drug release. Results: The hardness for the tablets was from 4.08 to 7.97 Kgf. The friability was from 0.02±0.45 to 3.40±0.43%. Tablets from formulations A1-A3, B2, and B3 failed the friability test. Formulations prepared with 1% SAG were more friable than those formulated with 2% SAG. Disintegration time for formulations A1-A3 (1% SAG + MS) ranged from 19.07 to 63.5 min, while that of A4-A6 (2% SAG + MS) was from 39.06 to 81.48 min. Formulations B1-B3 (1% SAG + SLS) had disintegration time that ranged from 4.22 to 6.8 min while that of B4-B6 (2% SAG + SLS) was from 9.35 to 15.90 min. The % drug release at 60 min for formulations that contained SAG and MS was 76.60-104.28% and SAG and SLS was 99.89-101.35% Conclusion: Metronidazole tablets formulated using SLS as lubricant disintegrated faster than those formulated using magnesium stearate as lubricant. Percentage drug release from tablets containing SLS was slightly higher than those that contained magnesium stearate. Higher concentrations of the lubricants produced softer tablets.

Fast dissolving oral delivery systems are solid dosage forms, which disintegrate or dissolve within 1 minute in the mouth without drinking water or chewing. Mouth dissolving film (MDF) is a better alternate to oral disintegrating tablets due to its novelty, ease of use and the consequent patient compliance. The purpose of this work was to develop mouth dissolving oral films of palonosetron HCl, an antiemetic drug especially used in the prevention and treatment of chemotherapy-induced nausea and vomiting. In the present work, the films were prepared by using solvent casting method with various polymers HPMC E3, E5 & E15 as a film base synthetic polymer, propylene glycol as a plasticizer and maltodextrin and other polymers. Films were found to be satisfactory when evaluated for thickness, in vitro drug release, folding endurance, drug content and disintegration time. The surface pH of all the films was found to be neutral. The in vitro drug release of optimized formulation F29 was found to be 99.55 ± 6.3 7% in 7 min. The optimized formulation F29 also showed satisfactory surface pH, drug content (99.38 ± 0.08 %), disintegration time of 8 seconds and good stability. FTIR data revealed that no interaction takes place between the drug and polymers used in the optimized formulation. In vitro and in vivo evaluation of the films confirmed their potential as an innovative dosage form to improve delivery and quick onset of action of Palonosetron Hydrochloride. Therefore, the mouth dissolving film of palonosetron is potentially useful for the treatment of emesis disease where quick onset of action is desired, also improved patient compliance.

In the present work, orodissolving tablets of Efavirenz were prepared by direct compression method with a view to enhance patient compliance. A 23 full factorial design was applied to investigate the combined effect of three formulation variables. Amount of crospovidone, croscarmellose sodium and sodium starch glycolate were used as superdisintegrant material along with direct compressible mannitol to enhance mouth feel. The prepared batches of tablets were evaluated for hardness, friability, weight variation, disintegration time, wetting time, drug content and in-vitro dissolution studies. Based on wetting time, disintegration time, the formulation containing crospovidone (5% w/v), carscarmellose sodium (5% w/v) and sodium starch glycolate (8% w/v) was found to be promising and tested for in-vitro drug release pattern (in 0.1 N HCl), short term stability and drug- superdisintegrants interaction. Surface response plots are presented to graphically represent the effect of independent variables (conc. of superdisintegrants) on the in-vitro dissolution time. The validity of the generated mathematical model was tested by preparing extra-design check point formulation. The formulation showed nearly faster drug release compared to the conventional commercial tablet formulation. Stability studies on the optimized formulation indicated that there was no significant change found in physical appearance, hardness, disintegration time, drug content and in-vitro drug release.

The present research work was to evaluate the effect of compression force and concentration of superdisintigrant on tableting properties of metformin HCl. Initially powder mixtures of drug, croscarmellose sodium (0.62% to 10% w/w) and microcrystalline cellulose PH-200 sufficient quantity were prepared and evaluate their pre-compression parameters of different formulation batches such as angle of repose, bulk density, tapped density, Hausner’s ratio and compressibility index. The prepared powder mixtures of different batches were compressed into tablet using hydraulic pellet press machine at two optimized compression forces (77 MPa and 154 MPa). The post compression parameters such as thickness, diameter, weight variation, hardness, friability, drug content, disintegration time and in-vitro drug release study of the prepared tablets were evaluated. FT-IR and DSC studies showed that no incompatibility of the selected drug with the selected excipients. At selected compression force (77 MPa) and increased concentration of superdisintigration (0.62% to 10% w/w) of formulations F1 to F5 indicated that, disintegration time were periodically decreased up to F3 (1.25% w/w croscarmellose sodium). When the concen-tration of superdisintigrant increased up to 10% showed that disintegration time were periodically increased. Similarly, at compression force 154 MPa there is increased in tablet hardness but this effect was less significant when the superdisintegrant concentration more than 1.25% w/w. The hardness and drug content of all the formulations were found to be 3.59 ± 0.23 to 4.85 ± 0.01 kg/cm2 and 97.89 ± 0.10% to 99.42 ± 0.03% respectively. The in-vitro drug release data suggested that drug release of all the formulations followed Higuchi’s kinetic (R> = 0.998). The release rate exponent values (n) suggested the mechanism of drug release followed Quasi-Fickian diffusion mechanism at compression force 77 MPa and anomalous diffusion mechanism at compression force 154 MPa, respectively.

The current study was designed to convert the poloxamer (PLX) into thiolated poloxamer (TPLX), followed by its physicochemical, biocompatibilities studies, and applications as a pharmaceutical excipient in the development of tacrolimus (TCM)-containing compressed tablets. Thiolation was accomplished by using thiourea as a thiol donor and hydrochloric acid (HCl) as a catalyst in the reaction. Both PLX and TPLX were evaluated for surface morphology based on SEM, the crystalline or amorphous nature of the particles, thiol contents, micromeritics, FTIR, and biocompatibility studies in albino rats. Furthermore, the polymers were used in the development of compressed tablets. Later, they were also characterized for thickness, diameter, hardness, weight variation, swelling index, disintegration time, mucoadhesion, and in vitro drug release. The outcomes of the study showed that the thiolation process was accomplished successfully, which was confirmed by FTIR, where a characteristic peak was noticed at 2695.9968 cm−1 in the FTIR scan of TPLX. Furthermore, the considerable concentration of the thiol constituents (20.625 µg/g of the polymer), which was present on the polymeric backbone, also strengthened the claim of successful thiolation. A mucoadhesion test illustrated the comparatively better mucoadhesion strength of TPLX compared to PLX. The in vitro drug release study exhibited that the TPLX-based formulation showed a more rapid (p < 0.05) release of the drug in 1 h compared to the PLX-based formulation. The in vivo toxicity studies confirmed that both PLX and TPLX were safe when they were administered to the albino rats. Conclusively, the thiolation of PLX made not only the polymer more mucoadhesive but also capable of improving the dissolution profile of TCM.
