BIORELEVANT DISSOLUTION MEDIA: ITS CURRENT STATUS AND FUTUTRE PERSPECTIVES
The landscape of dissolution media has been dynamically evolving with newer drugs entering the market among which most of them are either BCS class II or BCS class IV drugs exhibiting poor solubility. Conventional dissolution raises lot of doubts in the pharmaceutical industry owing to its composition which fails to adequately mimic in-vivo conditions. The effect of bile salts, enzymes are prevalent factors which are often neglected by conventional dissolution media. To overcome these hurdles biorelevant media was suggested by several research groups and several developments have been witnessed to maintain a proximity to the required in-vivo conditions during dissolution. Media such as simulated gastric fluid, simulated intestinal fluid, milk-based dissolution media (Ensure®) have been suggested for fast and fed state taking into the considerations several factors like pH, surfactant concentration, etc. The recent improvement has been on fast state simulated intestinal fluid (FaSSIF- V2) where replacement of acetic acid by maleic acid is evident. Though biorelevant dissolution media has solved the primary hurdle of mimicking in-vivo conditions, it has still not been accepted as a quality control tool to test batch to batch consistency in pharmaceutical industry. The reasons being cost, time consumption and basic requirement of dissolution as test as discriminatory tool where biorelevant media fails at certain fronts where conventional dissolution passes fairly well. The use of surfactants like bile salts in biorelevant media shows increased dissolution profile of different batches and fails to discriminate between them. It is a common understanding that those compounds which show increased dissolution in conventional media are obvious to show better dissolution in biorelevant media. This is the reason why conventional media are preferred over biorelevant media during quality control evaluation and batch to batch variability tests to save cost and time. Biorelevant media are being used today majorly during developmental stages and still need to go a long way to be used as quality control tool

Smart Walking System based on Artificial Intelligence
This paper shows the smart walking stick based on ultrasonic sensors and Arduino for outwardly debilitated individuals. There are roughly 37 million individuals over the globe who are visually impaired as indicated by the World Health Organization. Individuals with visual inabilities are regularly subjected to outer help which can be given by people, trained dogs, or electronic gadgets as supportive networks for basic assistance. Thus, this played as the motivation to develop a smart cane white stick to survive these restrictions which includes ultrasonic sensors at particular positions to the stick that gave data about nature to the client by initiating the signal sound and vibrations. We proposed minimal effort and light weight framework structured with micro controller that processes signal and alerts the visually impaired person over any obstacle, water or dark areas through beeping sounds or vibrations. The system comprises of obstacle and moisture detection sensors for process of receiving, processing and sending signals to the alarm system which finally alerts the user for prompt action. The system was designed, programmed using Java language and tried for exactness by the visually impaired. Our gadget can recognize obstacle inside the separation of around 2m from the client

Rationalized Approach for Formulation and Optimization of Ebastine Microemulsion Using Design Expert for Solubility Enhancement
Ebastine is available as an oral antihistamine formula for allergic disorders such as tablets and syrup. Oral ebastine causes unfavorable effects on heart like QT prolongation, severe gastric distress, decreased tear production, resulting in dryness of the ocular surface, which exacerbates ocular discomfort and increasing susceptibility of eye to irritation. To avoid systemic side effects and ocular discomfort, topical ocular therapy could prove to be superior to systemic therapy in treating ocular allergies. Hence, topical formulation was developed to achieve onsite exposure of ebastine for ocular allergies. Moreover, conjunctiva is more accessible to hydrophilic molecules than lipophilic molecules. This creates challenge for a lipophilic molecule such as ebastine for topical ocular development. Successful dissolution of ebastine in o/w microemulsion allows its use in more convenient soluble form. Initially, solubility of drug in various oils, surfactant and cosurfactant was determined, followed by pseudo-ternary phase diagram to find microemulsion area. The D-optimal mixture design was employed for optimization of formulation. The optimized microemulsion formulation was characterized for its transparency, drug content, droplet size, zeta potential, viscosity, isotonicity, osmolarity and surface tension etc. The optimum physicochemical properties were observed to be eye-fitting. Carboxy methyl cellulose and sodium hyaluronate were used as gelling agents at different concentrations to increase residential time at the site of action. In vitro drug release study revealed that ebastine release from microemulsion gel in a sustained manner up to 24 hrs. for the purpose of providing prolonged therapy for ocular allergy. Hence, prepared microemulsion had great potential as an alternative to customary oral formulations of poorly soluble drug.

HRheumatoid arthritis is the chronic painful disease of joint destruction and functional disability needing immediate action with patient compliance. Pain relieving Quick dissolving film (QDF) will be an accurate patient acceptable solution for this condition. Lornoxicam (LXM) is a non-steroidal anti-inflammatory drug (NSAID) with half life 3-5 hours, complete absorption from GIT (90-100%) having advantage from a tolerability standpoint. LXM has bitter taste thus to improve the palatability, the drug was complexed with Beta Cyclodextrin in different ratios using kneading method by optimizing the kneading time. Taste evaluation was done by human volunteer and UV method. The optimized drug-beta cyclodextrin complex was incorporated in QDF by solvent casting technique using PVA: Pullulan as polymers and PEG 400 as plasticizer. The optimization of concentration of PVA: Pullulan and PEG 400 was done by 32 factorial design to observe its effect on disintegration time, drug release in 20 minutes, tensile strength and folding endurance as dependent variable. The optimized batch QDF1 gave disintegration in 22 second and 98 % drug release in 20 minutes with suitable strength and flexibility. It can be concluded that the development of Quick dissolving film of Lornoxicam could give quick relief from the pain of rheumatoid arthritis with greater compliance compared to other conventional dosage forms.</jats:p
