In the present study bilayer patch of benzydamine HCl was developed using solvent casting method. Different substrates were attempted like Petri dish, glass-and-ring, and teflon-and-ring for selection of the proper option to formulate patch that should give easily peelable film with adequate mechanical properties. HPMC E15 LV was used in different concentrations for obtaining proper viscosity of solution for pouring on to surface and ring, that it should not leak from ring. The second layer was optimized by using different polymer like eudragit RSPO, eudragit RSPO + EC, and eudragit NE30 D for efficient layer bonding. The minimum release from backing membrane was established by diffusion study as compared to from drug loaded layer. The optimized batches were evaluated for folding endurance, weight variation, thickness, drug content, drug release, tensile strength, layer separation, mucoadhesion, moisture uptake, and layer bonding. The novel gingival patch of benzydamine HCl developed would be beneficial in optimizing the therapy.

The present investigation was aimed with the objective of developing fast dissolving oral films of Aripiprazole to attain quick onset of action for the better management of Schizophrenia. Fourteen formulations (F1-F14) of Aripiprazole mouth dissolving films by solvent-casting method using HPMC E5, HPMC E15, Maltodextrin, PG and PVA. Formulations were evaluated for their physical characteristics, thickness, folding endurance, tensile strength, disintegration time, drug content uniformity and drug release characteristics and found to be within the limits. Among the prepared formulations F13 showed minimum disintegration time 10 sec, maximum drug was released i.e. 99.49 ± 0.36% of drug within 8 min when compared to the other formulations and finalized as optimized formulation. FTIR data revealed that no interactions take place between the drug and polymers used in the optimized formulation. The in vitro dissolution profiles of marketed product and optimized formulation was compared and found to be the drug released was 20.73 ± 0.25 after 8 min. Therefore, it can be a good alternative to conventional Aripiprazole for immediate action. In vitro evaluation of the Aripiprazole fast dissolving oral films confirmed their potential as an innovative dosage form to improve delivery and quick onset of action of Aripiprazole. The mouth dissolving film is potentially useful for the treatment of Schizophrenia where the quick onset of action is desired.

Fast dissolving oral film is a new emerging solid dosage form in which it consists of thin strips administered orally and dissolved in mouth within the seconds. The study is purposed to use water soluble polymers to provide rapid film disintegration as the films are hydrated in mouth and to find the best polymer type and its concentration to formulate the drug. Initially, placebo films were prepared using solvent casting method then two formulations from the prepared placebo films were selected to formulate imipramine. The excipients were dissolved in water then the drug solution was prepared by dissolving 150 mg of drug in 5 ml of water then mixed with the excipients and they were mixed gently and casted in disposable Petri dishes and left for 24 h in oven to provide film dryness. Then, the films removed from Petri dish and cut to 2 cm × 2 cm small strips. Then, the tests were performed. Successful films were prepared by 45% hydroxypropyl methyl cellulose (HPMC) and 50% sodium carboxymethyl cellulose (NaCMC). The films were smooth, easily removed from Petri dish without tearing and homogenous. The thin films were mechanically stable that they could be handled without breaking due to their good folding endurance which was more than 400. The pH of the films was accepted since they were around saliva pH (5.3–6.9). The films disintegration time was <60 min since water-soluble polymers were used and this property provided rapid drug release from the formulation in which it was 15–20 min for both of the drug-containing films, while dissolution time for the imipramine conventional tablet was about 60 min. Imipramine can be formulated as a new dosage form (fast dissolving film) using 45% HPMC and 50% NaCMC as polymer using solvent casting method to ease the drug administration for psychotic and pediatric patients since no water is required for this solid dosage for administration.

Objective: The purpose of this study was to design and formulate mucoadhesive buccal patches of sodium cromoglycate (SCG) as an alternative way to overcome its poor oral absorption and short half-life.Methods: Mucoadhesive patches were prepared by solvent casting technique using cellulose acetate butyrate (CAB) alone or in combination with mucoadhesive polymers like SCMC (sodium carboxymethyl cellulose), HPMC 100M (hydroxyl propyl methyl cellulose) and Cbp934P (carbopol) in different concentrations. The successful patches were evaluated for thickness, weight variation, folding endurance, tensile strength, drug content, surface pH, moisture uptake, swelling percentage, mucoadhesion strength, residence time, in vitro release study, ex vivo permeation and in vivo pharmacokinetic studies.Results: The thickness of all prepared patches ranged from 0.210±0.006 to0.355±0.012, folding endurance was more than 300, weight variation did not exceed 0.179±0.015, tensile strength and % elongation ranged from 6.4±0.018 to 13.1±0.024, and from 30.4±0.88 to 53.4±0.78respectively. The swelling percentage after one hour was from 20.8±0.99 to 53.2±1.5. pH of all prepared patches did not exceed 6.8, the drug content was about 99 to 101%, moisture uptake did not exceed 10%. Mucoadhesion strength and residence time ranged from 17.2±0.14 to 51.2±0.26, and from 3.35±0.25 to 7.45±0.28 respectively. The cumulative release percentage of SCG was in the following descending order CAB>CAB with Cbp934P>CAB with HPMC>CAB with SCMC. The optimized patch (F9) decreased the Cmax and increased Tmax compared to the parenteral solution.Conclusion: It can be concluded that mucoadhesive buccal patch is a promising dosage form to prolong the release of SCG and enhance its poor oral bioavailability.

abstract This study investigated the development and characterized the physicochemical properties of films obtained from by-products (BP) from the preparation of propolis extracts. Films were produced in the presence and absence of a polymeric adjuvant (gelatin or ethylcellulose) and propylene glycol by a solvent casting method. Density, surface topography by scanning electron microscopy, mechanical properties (folding endurance, tensile strength and percentage elongation), water vapour permeability (WVP), moisture uptake capacity, thermogravimetry, differential scanning calorimetry and Fourier transform infrared spectroscopy (FTIR) were determined. The films were a transparent, light greenish-yellow colour, with a uniform surface, and were flexible and easy to handle. The thickness and density of the preparations indicated that the compounds were homogeneously dispersed throughout the film. Mechanical properties were influenced by the film composition; films containing gelatin were more resistant to stress, while those containing ethylcellulose were more flexible. Increasing the adjuvant concentration decreased the elasticity and the rupture resistance, but increased the moisture uptake capacity and WVP of the formulations. BP was thermally stable as were the films. FTIR tests suggested interactions between BP and the adjuvants. This work could contribute to the utilization of BP to prepare films for food and pharmaceutical uses

Despite the rapid increase in the utilization of reinforced nanomaterials composites, micromaterials may also have the potential to be utilized as filler in polymer composites. In this study, the activated carbon (AC) filled epoxidized natural rubber (ENR) composite was fabricated using the solvent casting method. AC was used as the filler at different filler addition in range from 0 to 7 parts per hundred rubbers (phr). The intention was to investigate the effect of AC filled ENR on mechanical properties and interaction between AC and ENR matrix. Overall, the result shows high improvement in mechanical properties. At 7 phr, the tensile strength was 7.0 MPa compared to 2.6 MPa for 0 phr, which indicates the increase by almost 2 times. The elongation also increases for all phr, which indicates the good filler effect.
