In today's fast-paced society, individuals are subjected to numerous forms of stress, and the majority of the world's population suffers from various neurological disorders. The imbalance of excitatory and inhibitory neurotransmitters is one of the mechanisms driving epilepsy. Epileptic seizures can cause loss of awareness, tremors, disorientation, difficulties reacting, and visual or other sensory symptoms, depending on which parts of the brain are implicated. The usage of benzodiazepines, barbiturates, and ion channel modulators in the treatment of epilepsy was categorised depending on the place of origin and symptoms. Allopathic treatment should typically begin with a single antiepileptic medication. Ayurvedic treatment approaches include purifying measures such as therapeutic purgatives and pacifying therapies such as single herb and polyherbal formulations. The review's goal is to look at pathogenesis, epilepsy categorization, signs and symptoms, allopathic and Ayurvedic medicine therapy, and future trends in epilepsy.

The objective of the study was therefore to evaluate the role of 6-shogaol in the antidepressant effect Zingiber officinale using two different animal models viz., tail suspension test and forced swim test. Ginger rhizomes were extracted using water-methanol (80/20) as the solvent using maceration and 6-shogaol was isolated from the extract using mixture of n-hexane-diethyl ether (70/30, v/v) in column chromatography. The yield of the isolated 6-shogaol after column chromatographic isolation of the aqueous methanolic ginger extract was found to be 1.3%. The isolated 6-shogaol was of pale-yellow color and the texture appeared to be fine and crystalline. The forced swim test revealed that the immobility time was significantly reduced at all the administered doses of 6-shogaol in a dose dependent manner. The swimming time was found to increase in a similar fashion but was not significantly increased at a dose of 30 mg/kg of 6-shogaol. ANOVA analysis of the tail suspension test revealed that the reduction of immobility time was not significant at a dose of 30 mg/kg 6-shogoal whereas at doses of 100 and 300 mg/kg, the reduction was significant as compared to the control group. KEYWORDS: Shogaol, extract, tail suspension, forced swim, antidepressant, isolation.

Thiocolchicoside is a centrally acting analgesic and is used to treat moderate to severe pain. Thiocolchicoside is rapidly and almost completely absorbed after oral administration, showing good bioavailability. Hence the main objective of the work was to design, development and in vitro evaluation of natural gum based matrix tablet of Thiocolchicoside. All the batches were evaluated for angle of repose, carr’s index, hausner’s ratio, hardness, thickness, weight variation, drug content and in vitro release characteristics. The results of DSC and IR spectroscopy exhibited that no chemical interaction between drug and polymers and no shifting in the IR peaks was observed. The release kinetics and the mechanism of drug release by regression coefficient analysis were investigated. The optimized tablets having HPMC provided more sustained drug release than other polymers. The drug release from the tablets was sufficiently sustained and non-Fickian transport of the drug from tablets was confirmed. KEYWORDS: Thiocolchicoside, HPMC K15M, Carbopol 934P, MCC PH102.

This study describes a systemic approach for the formulation and evaluation of Efavirenz tablets and has been done in this work using Moringa Oleifera as a natural polymer at different concentrations. In order to identify the medication, melting point, solubility, and FTIR analysis were used. DSC was used for investigating the drug polymer interactions. Consequently, no interaction between the medicine and polymer used in the formulation was detected. The formulations were created by blending medication and excipients, then analysing them for Angle of repose, Bulk density, Tapered bulk density, Hausner's ratio, and Carr's compressibility index. The powder blends passed all of these tests with flying colours. Direct compression was used to make the seven batches of Efavirenz pills. Thickness, hardness, friability, weight variation, and drug content were all measured on the manufactured tablets. All of the values were found to be within the parameters. All seven batches were subjected to in-vitro dissolving tests. Because Formulation F7 has the largest percentage of medication release, it has been chosen as the best formulation. Stability tests were performed on the optimised formulation F7, and the findings showed no significant changes throughout the course of the three-month investigation.

A new RP-HPLC method was developed for the estimation of bilastine and montelukast in tablets and it was validated as per ICH guidelines. The chromatogram for was found to be satisfactory on symmetry C-18 (4.6×150mm, 5µ Thermosil column) using phosphate buffer (pH 4.5) and acetonitrile in the ratio of 30:70 v/v at a flow rate of 0.8 ml/min. The retention time of montelukast and bilastine were found to be 7.03 min and 9.50 min respectively. The system suitability parameters proved that the proposed method is suitable for simultaneous estimation of bilastine and montelukast. Tailing factor for the peak was found to be 1.003 and 1.258 for montelukast and bilastine respectively and the theoretical plates for separation were found to be 3409 and 7365 respectively montelukast and bilastine. The method was found to be linear in the range of 10-50µg/ml for both the drugs. The precision of the method was good and the recovery of drugs is well within the acceptance limits of 80-120%.

The Advancement of human living standards within the twenty-first century, the issues of worldwide global climate change, rapid population increase, and environmental pollution have grown increasingly critical. Human activities have put plenty of strain on the ecosystem. Water contamination is one amongst several environmental issues that has to be addressed immediately. The rise in water-related disorders provides a sensible estimate of the extent of environmental degradation. Humans can utilize it day by day. Water will be employed in a pharmaceutical laboratory or industry for the formulation, chemical synthesis, and cleaning, among other things. The ultimate wastewater in numerous pharmaceutical laboratories and industries is treated in a very sort of ways to get rid of effluent and pollutants. That water, on the opposite hand, are often used for gardening and planting. Compared to other traditional procedures like biological, physical, chemical, adsorption, and advanced oxidation processes, the mixture technique of Electro coagulation and Microbial Electro Cell lysis has high de-colorization efficiency, is economically attractive, and produces little sludge. Color, COD, BOD, turbidity, and metal ions are among the pollutants that will be far away from wastewater using the electro coagulation procedure. We are researching the processes of electro coagulation and microbial electro cell lysis in order to make a wastewater treatment system that is reusable and produces better outcomes. It is incredibly inexpensive and easy, with only some substances being utilized within the treatment and administration. We are considering the longer term when creating such a design. KEYWORDS: Laboratory waste water, Electro-coagulation, Microbial electro cell lysis, Electrodes.
