Objective: Oral metoprolol tartrate has a short elimination half-life (2-3h) and low bioavailability undergoes extensive first-pass metabolism and frequent dosing. The aim of the present investigation was to formulate, develop and evaluate metoprolol tartrate transdermal patches using various synthetic and natural penetration enhancers. Methods: Enhancers used were eugenol, limonene, basil oil, urea and SLS (sodium lauryl sulphate). Polymer used was chitosan and PEG 400 used as a plasticizer. Transdermal Films were prepared by using solvent casting method. FTIR and DSC were studied to assess any interaction between the drug and polymers. Films were evaluated for Physico-chemical Characteristics like thickness, weight variation, folding endurance, moisture loss, moisture absorption and drug content. In vitro skin permeation studies were performed using Keshary chien cell For 24 h across rat skin. Results: Chitosan was found to be a suitable polymer for matrix formation. 3.5% w/w was used to optimize to formulate transdermal patches. 1.5% of total solution v/v lactic acid was used for dissolution of chitosan. 2.5%v/v of total solution PEG 400 was used to provide plasticity and smoothness to the patches. From the evaluation of patches formulation, F10 containing Basil oil as penetration enhancer in the concentration of 1.5% v/v was found to be best among all batches because of its consistent release rate For 24 h and extent of drug release was 85.20%. It can be concluded that naturally occurring volatile oils i.e., terpenes appear acceptable permeation enhancer and shows the best permeation across skin as indicated by high percutaneous enhancement ability. Conclusion: The developed transdermal patches are stable, non-irritating, and had increased efficacy of metoprolol and therefore had a good potential for hypertension treatment.

Objective: The current study emphasizes on the treatment of ocular infection with objectives of reducing the frequency of administration, obtaining controlled release and greater therapeutic efficacy of the drug (ofloxacin) using ocular films.Methods: Ocular films were designed by solvent evaporation method containing a different combination of polymers. The folding endurance (mechanical strength) was determined by the number of folds at a specific single place required to break the film into two parts. Thickness was measured using screw gauze. The surface pH was done by pH paper. The percentage moisture absorption was carried out by placing the ocular films in a desiccator containing ammonium chloride. Percentage moisture loss was carried out by placing the ocular films in the desiccator containing anhydrous calcium chloride. in vitro drug release study were carried by using a modified version of franz diffusion cell. Stability study were carried using stability chambers as per ICH guidelines. The antibacterial activity was performed by using male albino rabbits.Results: The thickness and folding endurance of the films were in the range of 44±1.1 to 92±1.8 and 4.5±0.6 to 6.8±0.3, respectively for different formulations. Surface pH was evaluated in the range of 6.6 to 7.2. Percentage moisture absorption and percentage moisture loss were evaluated in the range of 1.17±1.1 to 6.72±1.5 and 0.58±0.9 to 1.23±0.9 respectively. Microbial growth was not observed in any formulation during sterility testing. The drug release for different batch codes PAH, PBE, PCP, PDC, PEEH, and PFEC was found to be 96.2, 56.9, 93.4, 94.5, 98.4 and 95.9 % respectively up to 12 h. Ocular films of batch code PEEH was optimized for maximum drug release (98.4%).

The study was aimed to formulate a dental film containing linezolid, a broad spectrum antimicrobial agent which could be easily placed into the periodontal pocket and be capable of delivering therapeutic concentrations of drug for prolonged periods and also reducing the side effects. In the present investigation, chitosan strips containing linezolid in three different concentrations (10, 20, and 30 %w/w with respect to the weight of polymer) were prepared by the solvent casting method, by using 1 %V/V acetic acid solution. The prepared formulations were evaluated for various properties such as weight variation, thickness, folding endurance, moisture loss, tensile strength, in vitro release, release kinetic study and stability studies. The weight variation and thickness were found to be in the range of (0.99-1.58 mg) and (0.92-1.76 mm), the moisture content, folding endurance was found to be maximum for the plain film and minimum for the drug containing formulation. The tensile strength was found to be in the range of (2.44-1.43 kg/ mm2 ) for the formulation. The dissolution studies showed a burst release initially followed by a progressive fall in the release of the drug (91.15 - 95.87 %) and the release kinetics followed the zero-order pattern. The short term stability studies were conducted and there were no significant changes observed. Hence, low dose, site-specific linezolid film is a potential tool for the treatment of periodontitis.

The most used pharmaceutical formulations for children are syrups, suppositories, soft chewable capsules, and mini-tablets. Administrating them might create an administration discomfort. This study aimed to develop and evaluate orodispersible films (ODFs) for pediatric patients in which the fluoxetine (FX) is formulated in the polymeric matrix. Six FX fast dissolving films (10 mg FX/ODF), FX1, FX2, FX3, FX4, FX5, and FX6, were prepared by solvent casting technique. In the composition of the ODFs, the concentration of the hydroxypropyl methylcellulose and the concentration of the propylene glycol were varied. Each formulation of fluoxetine ODF was evaluated by determining the tensile strength, folding endurance, disintegration, behavior in the controlled humidity and temperature conditions, and adhesiveness. All the obtained results were compared with the results obtained for six ODFs prepared without FX. The disintegration time of the FX ODFs was of maximum 88 s for FX2. Via the in vitro releasing study of the FX from the ODFs it was noticed that FX1 and FX2 allow a better release of the drug 99.98 ± 3.81% and 97.67 ± 3.85% being released within 15 min. From the obtained results it was also confirmed that FX ODFs were found to follow first-order release kinetic.
