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.

Objective: The aim of the present work was to develop and characterize mucoadhesive film of spray dried Lovastatin (LVS) for buccal delivery to enhance bioavailability. Methods: Mucoadhesive films were prepared by solvent casting technique by using different polymers HPMCK4M, HPMC E5LV and chitosan. The successful patches were evaluated for film thickness, weight, content uniformity, surface pH, swelling index, folding endurance, ex-vivo residence time, ex-vivo bioadhesion test, in vitro drug release, ex-vivo drug permeation and stability study. Results: The thickness of all prepared patches ranged from 0.21±0.07 to 1.5±0.39 mm, the weight of the film 89.10±0.6 to 128.57±0.3 mg, drug content 85.47±0.87 to 97.33±0.31%, surface pH 5.6±0.67 to 7.6±0.98, swelling index 23.0±4.1 to 76.5±3.6%, folding endurance 165±1.9 to 350±2.5 respectively. Ex-vivo residence time ranged from 2.2±0.08to 8.2±0.17 h and ex-vivo bioadhesive strength 30±0.64 to 66±0.43 g. The formulations with HPMC E5 shown short period of residence time and shows weak force of adhesion., which might be because of low viscosity of the polymer which resulted into weak adhesion. The percentage drug release and ex-vivo drug permeation was in the following descending order HPMC K4M>HPMC E5LV>chitosan. These results confirm the extension of drug release in case of ionic polymer chitosan. The kinetics data shows that drug release and permeation follows nonfiction diffusion. Accelerated stability data revealed that there is no significant change in drug content, in vitro drug release and ex-vivo permeation. Conclusion: It can be concluded that mucoadhesive buccal patch is a promising dosage form to enhance the drug bioavailability by preventing first-pass metabolism thus providing better therapeutic efficacy.

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.

Objective: The objective of the present study was to design and optimize oral fast dissolving film (OFDF) of practically insoluble drug lafutidine in order to enhance bioavailability and patient compliance especially for a geriatric and unconscious patient who are suffering from difficulty in swallowing.Methods: The films were prepared by a solvent casting method using low-grade hydroxyl propyl methyl cellulose (HPMC E5), polyvinyl alcohol (PVA), and sodium carboxymethyl cellulose (SCMC) as film forming polymers. Polyethylene glycol 400 (PEG400), propylene glycol (PG) and glycerin were used as a plasticizer to enhance the film forming properties of the polymer. Tween 80 (1% solution) and poloxamer407 were used as a surfactant, citric acid as a saliva stimulating agent, and croscarmellose as a super disintegrant. Films were then tested for both physical (weight variation, thickness, surface pH, drug content) and mechanical (folding endurance, tensile strength, percent elongation, Young's modulus) characteristics. In vitro disintegration, time and drug release profile were also determined for each formula.Results: Films were found to be satisfactory when evaluated for both physical and mechanical characterizations. The surface pH of all the films was found to be within the range of salivary pH 6.8. The USP dissolution apparatus type II (paddle type) was used for in vitro drug release studies. The optimized formulation F13 gave 100 % of drug released at 2 min. It also showed satisfactory surface pH (6.2±0.2), drug content (100.1±0.01%), the disintegration time of (7.0±0.5) seconds and the time needed for 80% of medication to be released (T80%) was 0.96 min.Conclusion: Lafutidine OFDF was formulated using HPMC E5 as film-forming a polymer with PEG400 as a plasticizer. Combination of tween80 (1% solution) and poloxamer407 as a surfactant were used in the presence of croscarmellose as a super disintegrant. The chosen OFDF disintegrates within seven seconds, releases the drug rapidly and gives an action.

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.

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.
