Loratadine, a second generation H1-receptor antagonist, works by blocking the action of histamine and is widely prescribed for itching, runny nose, watery eyes, and sneezing from "hay fever" and other allergic conditions. To ensure quality the main requirements for a medicinal product are safety, potency, efficacy and stability. This research work aimed to compare and assess the quality levels of different local brands of loratadine tablets available in the drug market of Bangladesh. Six different brands of loratadine 10 mg tablet manufactured by the local companies were used for the analysis. The evaluation was performed through the determination of weight variation, hardness, friability, percent potency, disintegration time, and dissolution profile in accordance with USP-NF specifications. All brands showed acceptable weight variation and % friability. The percent potency for tested samples by UV method ranges from 97.02%-108%, showing none of the brands contains less than 90% of the active principle as per the specification. The result of the physical and chemical studies, such as in-vitro dissolution, disintegration, hardness, etc., has been found to differ but lie within the specified limit. After analyzing the data obtained from the tests, it can be claimed that loratadine 10 mg tablets manufactured and marketed by several local companies in Bangladesh meet the quality standard required to achieve the desired therapeutic outcomes.

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.

In present research work, taste masked Mouth Dissolving Tablets (MDTs) of Ranitidine Hydrochloride were designed with a view to enhance the patient compliance and provide a quick onset of action. Taste masking of the drug was done by formation of complex with β cyclodextrin. Tablets were prepared by direct compression, using superdisintegrants like crosscarmellose sodium and crosspovidone in different proportion and evaluated for the pre-compression parameters such as bulk density, compressibility, angle of repose etc. In view of the better taste palatability of such a bitter API, taste masking was carried out via making the cyclodextrin complex and sucralose was used as the sweetener to impart a palatable taste to the formulation. The prepared batches of tablets were evaluated for hardness, weight variation, friability, drug content, disintegration time and in vitro dissolution profile and found satisfactory. Among all, the formulation F7 containing 5% w/w proportion of both crosscarmellose sodium and crosspovidone was considered to be best formulation, which disintegrated completely in 19 seconds and released up to 98.38% of the drug.

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.

Background: The outcome of the drug therapy depends largely on the quality of the drug product. The lower quality of the drug product can be the reason for therapeutic failure. The present study was designed to evaluate the quality standard of Losartan Potassium tablet brands available in Bangladesh market to get an idea of quality standard of drug product people consuming in this country. Materials and methods: Three brands of losartan potassium were chosen randomly. Tablets of each brand were collected from individual retail outlets to gauge the qualitative evaluation and compare them by in-vitro drug release study. They were subjected to various quality control tests to measure the hardness, thickness, weight variation, friability, disintegration time, potency, stability, and dissolution profile. All these tests were performed according to the U.S. Pharmacopeia (USP) specification. Researchers further formulated a batch of tablet of Losartan Potassium and compared them with the existing brands. The formulation was prepared by optimizing the existing one available in the USP. Test results of the existing brands were taken into consideration during the optimization of the formulation. Results and discussion: Two brands passed the weight variation test, while one brand exceeded the range (±5%). The potency was determined instantly and 15 days after keeping the tablets in a stability chamber at 75% humidity and 60oC temperature. The potency of two brands degraded below the lower limit specified by the USP, while that of the remaining one was within the limits. Results of other tests were within the specified limits. Tablets prepared in the lab using an optimized formulation showed a better dissolution rate than the existing brands. Conclusion: Some of the brands failed to meet the desired quality, so the quality control system of that companies should be upgraded and a proper monitoring system should be developed by the drug administration.

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.

The purpose of the current study was to develop a fast dissolving polymeric oral thin film containing palonosetron hydrochloride having good mechanical properties, fast disintegration, dissolution and good drug content uniformity. Solvent casting method was used to prepare the films. Compatibility between drugs and excipients were studied using FTIR and HPLC. Nine different formulations of film from F1 to F9 were prepared using different concentration of polymer A at drug-polymer A ratio (1:26), (1:28), (1:30), (1:32), (1:34), (1:36), (1:38), (1:40), (1:42) and at polymer A-plasticizer B of (65:10), (70:10), (75:10), (40:10), (42.5:10), (45:10), (47.5:10), (50:10), (52.5:10), respectively. The in vitro dissolution study was carried out in phosphate buffer (pH 6.8) at 37±0.5oC and 50 rpm using USP XXIV paddle method. Physicochemical evaluations of all the batches were performed including weight variation, thickness, folding endurance, pH, in vitro disintegration and drug release, FTIR and content uniformity test. Maximum and minimum drug dissolution were found in F6 (108.7%) and in F1 (98.5%), respectively. The maximum and minimum disintegration time were in F9 (43.8 sec) and F1 (25 sec), respectively which demonstrated that disintegration of the film was directly proportional to the polymer A and plasticizer B concentration. It is quite evident from the present research work that the film prepared using polymer A-plasticizer B were smooth, mechanically strong and easy to peel out. Among all the batches, formulation F5 showed best results with respect to disintegration (33 sec), drug dissolution (105%), content uniformity (98.51%) and folding endurance (731). Therefore, it can be said that combination of polymer A and plasticizer B can be prospectively used for the preparation of palonosetron hydrochloride oral thin film.

The aim of this study was to design orally disintegrating tablet (ODT) of Lamotrigine. It is an Antiepileptic drug which is widely used in epilepsy. It is also used in simple and complex partial seizures and secondary generalized tonic-clonic seizures. It is poorly water soluble drug (0.46 mg/ml). Thus, an attempt was made to enhance the water solubility by complexation with β-cyclodextrin (1:1 molar ratios). The orally disintegrating tablet of lamotrigine was prepared by direct compression method using different concentration of superdisintegrants such as Sodium starch glycollate, croscarmellose sodium by sublimating agent such as camphor. The formulations were evaluated for weight variation, hardness, friability, drug content, wetting time, in vitro disintegration time and in vitro dissolution studies. The prepared tablets were characterized by Fourier transform infrared spectroscopy and differential scanning calorimetry. The disintegration time for the complexed tablets prepared by different concentration of superdisintegrants was found to be in range of 32.54 ± 0.50 to 55.12 ± 0.57 sec and wetting time of the formulations was found to be in range of 28.47 ± 0.67 to 52.19 ± 0.72 sec. All the formulation showed almost 100 percent of drug release within 15 min. Among all the formulation F6 and F7 prepared with 18% croscarmellose sodium and camphor shows faster drug release, respectively 10 min, F6 gives good result for disintegration time, drug release, wetting time and friability. Further formulations were subjected to stability testing for 30 days at temperature of 40 ± 5 ºC/75 ± 5 %RH. Tablets showed no appreciable changes with respect to physical appearance, drug content, disintegration time and dissolution profiles. Results were statistically analyzed by one-way ANOVA at a p < 0.05. It was found that, the data at any point of time are significant at p < 0.05.
