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.

Rebamipide, an amino acid derivative of 2-(1H)-quinolinone, is used for mucosal protection, healing of gastroduodenal ulcers, and treatment of gastritis. The current research study aimed to develop novel gastro-retentive mucoadhesive microspheres of rebamipide using ionotropic gelation technique. Studies of micromeritic properties confirmed that microspheres were free flowing with good packability. The in vitro drug release showed the sustained release of rebamipide up to 99.23 ± 0.13% within 12 h whereas marketed product displayed the drug release of 95.15 ± 0.23% within 1 h. The release mechanism from microspheres followed the zero-order and Korsmeyer-Peppas (R2 = 0.915, 0.969), respectively. The optimized M12 formulation displayed optimum features, such as entrapment efficiency 97%, particle size 61.94 ± 0.11 µm, percentage yield 98%, swelling index 95% and mucoadhesiveness was 97%. FTIR studies revealed no major incompatibility between drug and excipients. SEM confirmed the particles were of spherical in shape. Optimized formulation (M12) were stable at 40°C ± 2°C/75% RH ± 5% RH for 6 months. In vivo studies were performed and kinetic parameters like Cmax, Tmax, AUC0-t, AUC0-∞, t1/2, and Kel  were calculated. The marketed product Cmax (3.15 ± 0.05 ng/mL) was higher than optimized formulation (2.58 ± 0.03 ng/mL). The optimized formulation AUC0-t (15.25 ± 1.14 ng.hr/mL), AUC0-∞ (19.42 ± 1.24 ng.hr/mL) was significantly higher than that of marketed product AUC0-t (10.21 ± 1.26 ng.hr/mL) and AUC0-∞ (13.15 ± 0.05 ng.hr/mL). These results indicate an optimized formulation bioavailability of 2.5-fold greater than marketed product.

Clobazam orally dissolving strips were prepared by solvent casting method. A full 32 factorial design was applied for optimization using different concentration of film forming polymer and disintegrating agent as independent variable and disintegration time, % cumulative drug release, and tensile strength as dependent variable. In addition the prepared films were also evaluated for surface pH, folding endurance, and content uniformity. The optimized film formulation showing the maximum in vitro drug release, satisfactory in vitro disintegration time, and tensile strength was selected for bioavailability study and compared with a reference marketed product (frisium5 tablets) in rabbits. Formulation (F6) was selected by the Design-expert software which exhibited DT (24 sec), TS (2.85 N/cm2), and in vitro drug release (96.6%). Statistical evaluation revealed no significant difference between the bioavailability parameters of the test film (F6) and the reference product. The mean ratio values (test/reference) of Cmax (95.87%), tmax (71.42%), AUC0−t (98.125%), and AUC0−∞ (99.213%) indicated that the two formulae exhibited comparable plasma level-time profiles.

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.

A total of nine formulations of fast dissolving films of Losartan Potassium were developed by solvent casting method using film forming polymers such as HPMC E5, E15 and E50 and other film modifiers. The appearances of films were transparent, thin, flexible, elastic, smooth and transparent. The weight variation ranged between 16.14 ± 0.192 and 17.31 ± 0.313 and showed that there was no significant difference in the weight of individual formulations. All the formulations showed more than 150 of folding endurance. The drug content was found to be in an acceptable range for all the formulations which indicated uniform distribution of drug. A rapid dissolution of all the film was observed by the dissolution test, in which above 90% of Losartan Potassium was released within 5 min. The formulation F1 showed maximum drug release (98.73) within 5 minutes. Based on the in vitro drug release, drug content and in vitro disintegration time it is found that F1 was selected as the best formulation. The formulations showed satisfactory physical stability at 40°C at 75 % RH. Losartan Potassium (LOSAR-25) is shown in Figure 4. From the results of comparative studies of marketed product and it found that F1 showed 98.73% release within 5 min and LOSAR 25 showed 90.76% release in 30 min. In vitro studies indicate that this potential drug delivery system has considerably good stability and release profile. Nevertheless, further in vivo studies are warranted to confirm these results.

The main objective of the present study was to develop colon-targeted tablets of mesalazine by wet granulation method using 33 Response surface method with design of experiment software and HPMC K4M, Eudragit RL100, Ethyl cellulose and PVP K-30 used as pH dependent polymers. All the formulations (F1 to F27) were evaluated for the physicochemical parameters and were subjected to in vitro drug release studies. The amount of Mesalazine released from tablets at different time intervals was estimated by UV spectrophotometer. The formulation F26 released 98.16 % of mesalazine after 24 h, whereas marketed product drug release was 92.02 ± 2.15 after  24 h. From in vivo bioavailability studies, after oral administration of colon targeted tablet containing 400 mg mesalazine, the Cmax, Tmax, and AUC0–∞ of optimized formulation and marketed product was found to be 683.21 ± 0.03 ng/mL, 6.01 ± 0.04 h, 4150.12 ± 5.12 ng*h/mL and 445.34 ± 3.22 ng/mL, 4.00 ± 0.01 h, 3457.18 ± 5.32 ng*h/mL respectively. Cmax, Tmax and AUC values of optimized formulation were found to be significantly higher than of marketed product. The pH dependent tablet system is a promising vehicle for preventing rapid hydrolysis in gastric environment and improving oral bioavailability of mesalazine for the treatment of disease at colon region.

Objective of the investigation was to develop gastro retentive dosage form of gemifloxacin mesylate for local action in the stomach as it has antibacterial activity against Helicobacter pylori. Gemifloxacin mesylate is a synthetic broad-spectrum antibacterial agent for oral administration, having 7 hrs half-life and 71% oral bioavailability. In present study, gemifloxacin mesylate floating matrix tablets were prepared by direct compression method using polymers (HPMC K4M, HPMC K15M and polyox WSR 1105) and evaluated for various parameters like drug content, floating behavior (floating lag time and total floating time), in vitro drug release, swelling index, weight variation, friability, hardness and thickness. Sodium bicarbonate was incorporated as gas generating agent in all formulations. Drug-excipients compatibility was studied by Differential Scanning Calorimetry. Results have shown that the amount of polymer in the formulation affected the drug release. Optimized formulation (F8 containing polyox WSR1105 as release retarding agent) was selected based on in vitro drug release, floating lag time, floating time and other parameters. This formulation followed zero order kinetics and non-Fickian mechanism of drug release. In vivo radiographic study was conducted in healthy human volunteers using tablets containing BaSO4 as radio opaque agent. The average residence time was found to be 4.5± 0.86 h (n=3). This design of gastro retentive drug delivery system helps in increasing the local delivery of drug in patients with Helicobacter pylori infection
