Objective: The objective of this research was to formulate cinnarizine tablets using the liquid-solid compact technique to enhance its solubility and dissolution rate.Methods: Cinnarizine liquid-solid compacts were formulated using propylene glycol as the non-volatile solvent, Neusilin US2 as the carrier material, Aerosil 200 as the coating material and croscarmellose sodium as the disintegrant. The interaction between drug and excipients were characterized by Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) studies. Different batches of liquid, solid compacts were prepared by using varying carrier-coating excipient ratio and different concentration of liquid medication. Flow parameters such as bulk density, tapped density, Carr’s Index, Hausner’s Ratio as well as an angle of repose were used to test the flowability of the powder blend. The liquid-solid compacts were produced by direct compression method and were evaluated for tests such as weight variation, drug content, hardness, thickness, friability, wetting time, disintegration time as well as the in vitro dissolution studies.Results: The results of the preformulation studies of liquisolid compacts showed acceptable flow properties. The results of FTIR and DSC studies showed that there is no drug-excipient interactions. The different R values and concentrations were found to have a marked effect on the dissolution profile. Formulations with higher carrier: coating ratio (R-value) and lower drug concentrations displayed a better dissolution profile. The percentage of drug release of F3 with an R-value of 20 and a drug concentration of 10% was found to be 88.11% when compared to the conventional marketed tablet which released only 44.07% at the end of 2 h.Conclusion: From this research, it is inferred that liquid-solid technique is a promising and effective approach that can be used to enhance the dissolution rate of cinnarizine.

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.

 Fenofibrate is a drug included in BCS class II category, generally used to reduce cholesterol level in patient having a risk of cardiovascular disease. The main aim of this research was to ameliorate solubility and dissolution profile of Fenofibrate with comparison between two different methods i.e. Solid dispersion and liquisolid technique. In liquisolid system, a dry freely flowing and compressible powder mixture was obtained which absorb drug solution or suspension in non-volatile solvent. While in case of solid dispersion drug was dispersed with suitable hydrophillic carrier with or without volatile solvent to get powder material. Two formulation of Fenofibrate solid dispersion were prepared by solvent evaporation method using β-CD as a hydrophillic carrier with ratios 1:1 and 1:3. In case of liquisolid technique, two liquisolid compacts were prepared with ‘R’ value 20:1 and 40:1 using Avicel PH 102 as a carrier and Aerosil 200 as a coating material. All the formulations were characterized by FTIR, DSC and solubility studies. Precompression studies of all the batches were done by determining angle of repose (25.100- 35.020), bulk density (0.51- 0.56 g/ml), tapped density (0.60-0.66 g/ml), carr’s index (15.61-19.03%) and hausner’s ratio (1.13-1.25). Post compression evaluation was done by checking hardness (4-5 kg/cm2), thickness (3.56-4.01mm), friability (0.54-0.75%), disintegration time (3.50-5.56min), drug content (80.34-95.05%) and in-vitro drug release (81.55-92.93%). Out of all the four batches SD2 batch that was prepared by solid technology showed an excellent result by releasing drug at  96.91 %. Key words-  Fenofibrate, Solid dispersion, Liquisolid compact, Avicel PH 102, Aerosil 200.
