The objective of the present study is to evaluate the quality of the marketed and self collected samples of Plumbago zeylanica L. roots on the standardization parameters. This study is planned mainly to confirm changes with quality of drug. Now a day’s more demand of herbal drugs for disease treatment, lack of knowledge of proper methodology and availability are promoting the practices of adulteration and substitution. Thus, the standardization of the plant crude drugs is necessary to maintain their therapeutic efficacy. Comparative studies were carried out to evaluate the standards of P. zeylanica L. with emphasis on organoleptic evaluation, physicochemical and phytochemical analysis. Samples were procured from local market and self collected to determine the qualitative and quantitative variations. The result indicates that self collected sample showed significant results with comparison to marketed sample.

Oral mucosal drug delivery system is widely applicable as novel site for administration of drug and controlled release action by preventing first pass metabolism and enzymatic degradation due to GI microbial flora. The oral cavity represents a challenging area to develop an effective drug delivery modelling. This arises due to the various inherent functions of the oral cavity (eating, swallowing, speaking, chewing), as well as the presence of the fluid that is involved in all these activities, saliva. This fluid is continually secreted into and then removed from the mouth. Oral Mucosa drug delivery system provides local and systemic action. The delivery of drugs through the buccal mucosa has attracted much research interest over the past two decades and numerous approaches, both conventional and complex, have been developed in an attempt to deliver a variety of pharmaceutical compounds via the buccal route. To outline the progress in the in vitro and in vivo modeling of Mucosal drug delivery and provide a critical review of currently used methods. The purpose of this review is to represent the modeling of oral cavity with Mucoadhesive drug delivery systems and clarify the potential alternative to conventional therapy.

The present study was focused on Gastro-retentive tablets of Quetiapine fumarate using hydrophilic polymers HPMC K 250 PH PRM, HPMC K 750 PH PRM and HPMC K 1500 pH PRM as release retarding agents. WSR 301 was chosen as resin, Sodium bicarbonate was used as effervescent agents. FTIR studies revealed that there is no interaction between the drug and polymers used for the formulation. The tablets were prepared by direct compression method and the release rate was found to decrease with proportional increase in the ratio of polymer to drug. Quetiapine fumarate has good water solubility and is absorbed well from stomach and therefore is a very good drug to be formulated into gastro retentive floating dosage form. In-vitro release profile of Quetiapine fumarate and marketed product when compared, the optimized formulation F19 showed drug release of 98.61% within 24 h whereas 96.78% of the drug was released from the marketed product within 1h. The major mechanism of drug release follows zero order kinetics and non fickian transport by coupled diffusion and erosion. Such a formulation of Quetiapine fumarate with extended drug release over 24 hours probably is the best formulation for the treatment of Schizophrenia with only one oral tablet a day thus minimizing the side effects with low drug dose. The optimized formulation remained stable when subjected to accelerated stability studies.

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.
