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.

Aripiprazole is an atypical antipsychotic agent used for treatment of schizophrenia, bipolar disorder and major depressive disorders. In the present work, oral  disintegrating tablets of aripiprazole were developed to  enhance the patient compliance and provide rapid onset of  action. The efficacy of aripiprazole is mediated through a combination of partial agonist activity at dopamine D2 and serotonin 5HT-1A receptors and antagonist activity at 5HT-2A receptors. It has a bitter taste and poor-solubility in water. Thus, the main objective of the study is to formulate taste masked oral disintegrating tablets of aripiprazole by using inclusion complex beta-cyclodextrin to achieve a better dissolution rate and further improving the bioavailability of the drug. Oral disintegrating tablets were   prepared by direct compression method using  super disintegrant like crospovidone, croscarmellose sodium,  sodium starch glycolate and combinations of  cros-povidone with croscarmellose sodium, and crospovidone with sodium  starch glycolate in different concentrations. They were evaluated for the pre-compression parameters such as bulk density, compressibility, Hausner ratio and angle of repose. The prepared batches of tablets were evaluated for hardness, weight variation, thickness, friability, drug content, disintegration time, wetting time,    in vitro dispersion time, and in vitro dissolution profile. All these parameters were found to be satisfactory. Among all, the formulation F15 containing crospovidone 5% + cros-povidone with croscarmellose sodium 5% was considered to be the optimum formulation, which released nearly 99% of the drug in 20 minutes with a disintegration time of 10. 20 seconds. These studies indicate the viability and benefits of oral disintegrating tablets of aripiprazole.

Metoclopramide Hydrochloride

Fast dissolving strips are used as novel approaches, as it dissolves rapidly in mouth and directly reaches the systemic circulation. In present research work, an attempt has been made to prepare mouth dissolving strips of Metoclopramide hydrochloride by using a novel film former Pullulan by solvent casting method. A33 full factorial design was utilized for the optimization of the effect of independent variables such as the amount of Pullulan, amount of PEF 400, amount of SSG on mechanical properties, and % drug release of strips. The drug compatibility studies using FTIR and DSC studies formulated strips were characterized for their physicochemical parameter like weight variation, visual appearance, folding endurance, thickness, disintegration time, drug content, and in vitro dissolution studies. FTIR and DSC studies revealed that the polymer is compatible with the drug. It was found that the optimum levels of the responses for a fast release strip could be obtained at low levels of Pullulan, PEG400, and SSG. The prepared strip was clear transparent and had a smooth surface. The surface pH was found 4.8 to 5.2 be in the range of to which is close to salivary pH, which indicates that strips may have less potential to irritate the oral mucosa, thereby they are comfortable. The drug release was found to be between 90.94 to 100.5% in 2 min. The in-vitro disintegration time of strips prepared with Pullulan was in the range of 19 to 57 sec. As the concentration of SSG increases the decrease in the disintegration time of strips a decrease. The dissolution rate increased with an increase in the concentration of SSG. Hence, it can be inferred that the fast dissolving oral strips of Metoclopramide hydrochloride may produce rapid action thereby improving bioavailability and enhance the absorption by avoiding the first-pass effect.
