Background: The goal of this prospective, randomised, double-blind research was to see how adding magnesium or dexmedetomidine to epidural bupivacaine in upper abdomen procedures affected the outcome.

Materials and Methods: Sixty ASA (American Society of Anesthesiologists) class I and II patients undergoing upper abdominal procedures were randomly assigned to either magnesium sulphate (Group M) or dexmedetomidine (Group D) as well as epidural bupivacaine for surgical anaesthesia. All of the trial participants were given an epidural anaesthetic with 8 ml of 0.5 percent bupivacaine and either 50 mg MgSO4 (Group M) or 1 g/kg dexmedetomidine (Group D). Duration of analgesia, total rescue analgesic requirement, hemodynamic parameters and any adverse events were monitored.

Results: Analgesia in the postoperative phase was better in Group BD, as was the need for rescue analgesics. Sedation was more common in Group BD.

Conclusion: Dexmeditomidine prolongs the duration of analgesia and produces significant sedation. As a result, combining dexemedetomidine with epidural bupivacaine may provide greater analgesia and arousable sedation.

Objective: Asthma is a chronic inflammatory lung disease that affects people of all ages and is a major cause of morbidity and death across the world. It need ongoing medical attention. High and exorbitant prescription prices are one of the most common causes of non-compliance and treatment failure. The cost of pharmaceuticals has a significant impact on patient treatment, particularly in underdeveloped nations. It has been shown that the cost of different brands of the same generic medicine varies greatly. If doctors are unaware, they may prescribe expensive brands, which will result in non-adherence. The purpose of this study was to determine the cost differences between several anti-asthmatic medicine brands.

Methods: From the newest edition of Drug Today 2017, the least and highest cost in Rupees (INR) of a certain anti-asthmatic agent made by several pharmaceutical firms in the same strength were listed. Each brand's cost ratio and percentage cost variance were recorded

Results: The costs of anti-asthmatic medications varied significantly in this investigation. The highest percent cost variation was found for Doxophylline 400 mg (3100%), followed Deflazacort 6 mg (1300%), Methylprednisolone 4 mg (1104%), Combination of Formoterol and Budesonide (444%), Salbutamol 4 mg caps (363%), Theophylline and Salbutamol combination(236%), Ketotifen      1 mg (217%). Fluticasone 50 mcg (0.4%), Cromolyn 20 mg (2%), Formoterol 12 mcg (11.5%), Tiotropium 18 mcg (11.5%), Ipratropium 20 mcg/200 mdi (19%), and others were determined to have the lowest percent cost fluctuations.

Conclusion: The government should look at the pricing control strategy for anti-asthmatic pharmaceuticals made by various Indian firms, so that the prices of different brands stay consistent, quality assured, and cheap. Doctors must prescribe logically, selecting cost-effective drugs depending on the health state of the country.

The antioxidant properties of ten (10) plant species from various Nigerian states were assessed utilising the DPPH, H2O2, and FRAP test techniques . In the DPPH assay, Piliostigma reticulatum exhibited the best scavenging property at the lowest concentration (6.25 g/ml), whereas C. accuminata exhibited the best scavenging property at the greatest concentration (100 g/ml) . The following is the trend at the lowest concentration:; P. reticulatum> A. digitata> T. indica> C. accuminata> V. paradoxa> B. diezelli> S. longipediculata> A. squamosa> P. biglobosa> S. singueana. While the trend at the highest concentration is as follows; C. accuminata> B. diezelli> T. indica> P. biglobosa> A. digitata> V. paradoxa> A. squamosa> P. reticulatum> S. longipediculata> S. singueana.  The H2O2 experiment revealed that B diezelli had the best scavenging ability at both the lowest (6.25) and highest concentrations (100).In addition, the following is the current trend:; B. diezelli> A. squamosa> S. longipediculata> S. singueana> V. paradoxa> P. bigloosa> C. accuminata> A. digitata> T. indica> P. reticulatum at the least concentration. While at the highest, the trend is as follows; B. diezelli>S. longipediculata> S. singueana> V. paradoxa> P. biglobosa> P. reticulatum> C. accuminata> A. digitata> T. indica. According to the FRAP assay, S. longipediculata had the most scavenging activity at the lowest concentration (6.25) while C. accuminata had the highest activity at the highest concentration. The following is the trend at the lowest concentration:; S. longipediculata> C. accuminata> T. indica> A. digitata> V. paradoxa> A. squamosa> P. reticulatum> P. biglobosa> S. singueana> B. diezelli. While at the highest concentration the trend is; C. accuminata> S. longipediculata> T. indica> A. digitata> A. squamosa> V. paradoxa> P. reticulatum> P. biglobosa> S. singueana> B. diezelli. In the FRAP assay, five (5) crude extracts (S. longepedicunlata, T. indica, A. digitata, A. squamosa, C. accuminata) were more active than the standard drug (ascorbic acid and butylated hydroxyl anisole) at higher concentrations. The methanol crude extract of Piliostigma reticulatum was more active in the DPPH assay than all other plants material. Annona squamosa and Parkia biglobosa methanol crude extracts were most active than the other extracts in the hydrogen peroxide assay.

The present research work deals with pre-formulation and formulation studies for development of solid dispersions with enhanced oral bioavailability. Gliclazide (GLC), an oral hypoglycemic agent, is characterized by low solubility in gastric fluid, low dissolution rate and inter-individual variability in bioavailability. The objective of this study was therefore to design optimized solid dispersions (SD) of GLC with a hydrophilic carrier viz., poloxamer 407 (PXM) by lyophillisation method in an attempt to enhance the aqueous solubility and therapeutic efficacy of the drug. Phase solubility study with increasing PXM concentrations (0.5 to 10% w/v) was done to study the influence of polymer concentration on solubility of GLC. SD’s of GLC and PXM in 1:1, 1:3 and 1:5w/w ratios were prepared by physical mixing and lyophillisation (freeze drying) method, followed by dissolution studies. A comparative in vivo study between optimized SD and GLC was conducted on twelve healthy New Zealand rabbits. The dissolution rate of GLC from the lyophilized dispersions was greatly enhanced as compared to those from physical mixtures and pure drug. The in-vivo studies indicated that the pharmacokinetic parameters following oral administration of the optimized SD and pure GLC were significantly different (P < 0.05). The peak serum concentration (Cmax) for the lyophilized SD and GLC were found to be 3.01±0.42 µg/mL and 2.27 ± 0.39 µg/mL respectively, whereas the time required to reach the peak serum concentration (Tmax) for the optimized SD was significantly shorter (2.16±0.41h) compared to that for GLC (4.33±0.52h). The relative bioavailability of the SD under in-vivo test was found to be 158.52%. These results demonstrate that the use of a suitable hydrophilic carrier like PXM to formulate SDs by the lyophillisation technique can rapidly accelerate the solubility and in vitro dissolution of a lipophilic drug like GLC. The suggested method provides good signs of improvement in the rate of absorption as well as bioavailability of gliclazide following oral administration and can be explored for other hydrophobic drug moities.

Nonalcoholic fatty liver disease (NAFLD) is a prevalent condition that can lead to major liver diseases such as hepatic fibrosis and hepatocellular carcinoma. The most common etiology is a sedentary lifestyle and taking a high-calorie diet. Presently there is no US FDA-approved drug available to treat NAFLD, and only dietary measures, increased physical activity, exercise, antioxidants are the options. In December 2020, the Drug Controller General of India (DGCI) had approved New Drug Application (NDA) for Saroglitazar Mg to treat NAFLD in India. This review describes in detail the pathophysiology, diagnostic methods, and potential targets for NAFLD prevention and treatment.

Postnatal period is the period with increased vulnerability to psychiatric illness, if the mother fails to adopt positive coping strategies. Postpartum period is associated with intense physical and emotional changes leading to anxiety.

Objectives: The present study aimed to identify the perceived postpartum stress among postnatal mothers, identify coping strategies adopted by postnatal mothers, find out correlation between the level of perceived postpartum stress and coping strategies among postnatal mothers and find out the association between the level of perceived postpartum stress and demographic variables.

Methods: A quantitative descriptive study was conducted among 100 postnatal mothers. Convenience sampling technique was used. Hung postpartum stress scale and coping strategies inventory short form were used for the assessment of postpartum stress and coping strategies.

Results: Among the 100 participants, 63% of the postnatal mothers had mild stress, 33% had moderate stress, and only 4% had severe stress. Majority of the mothers were used problem-focused engagement as a coping strategy. There was a positive correlation found between the level of perceived postpartum stress and coping strategies such as emotion-focused engagement and emotion-focused disengagement. There was significant association found between the level of perceived postpartum stress and demographic variables such as age, education, length of marriage, status of pregnancy, method of baby feeding, pregnancy events, intrapartum events, birth weight of baby, child birth experience, status of newborn, and postpartum events.

Conclusion: The high proportion and severity of postpartum stress observed among this study group proves that postpartum stress is common and cannot be ignored.

Medical students, being the future doctors, should contribute significantly, but research among medical students is very poor with respect to presentations and publications.

Objectives: To identify the various barriers, motivational factors and attitude for conducting research.

Methods: This was a cross-sectional observational study involving 3 different batches of medical students by giving a semi-structured questionnaire.

Results: The response among the participants to involve in research was only 30%. Among them, the overall attitude and barrier score were 3.69±0.29 and 3.63±0.42, respectively, with statistical significance being shown between genders and not between batches. The biggest barrier was a lack of previous research experience (91.67%). The most common motivational factor was self-interest (90.7%).

Conclusions: If given sufficient training and facilities provided, we should be able to get more research done by the medical students.

Background: Hypertension, a common cardiovascular disease, is being increasingly associated with other co-morbid conditions like Diabetes mellitus, worsening its outcome. Both telmisartan and ramipril are effective anti hypertensive agents. The present study compares the efficacy of telmisartan and ramipril in controlling or preventing the progression of pre-diabetes to diabetes in stage 1 hypertensive patients. It also aims at assessing the effect of Telmisartan and Ramipril on FBS and HbA1C over 12 months treatment period in males and females and compare it.

Methods: A prospective, randomised, single centre, comparative observational study is conducted over a period of 12 months on stage 1 hypertensive patients with pre-diabetes. 60 patients are recruited and randomised into two treatment groups. They received the assigned drug for a period of 12 months and are followed up. At each visit, blood pressure was measured and diabetic profile was tested.

Results: This study showed that both telmisartan and ramipril controlled the blood pressure effectively. Telmisartan controlled the progression of fasting blood sugar and glycosylated haemoglobin better than ramipril in stage 1 hypertensive patients with pre diabetes.

Conclusions: Both telmisartan and ramipril were affecting in controlling the blood pressures. Telmisartan has a statistically significant effect in preventing the progression of prediabetes to diabetes mellitus in stage 1 hypertensive patients with pre diabetes when compared with ramipril.

Conclusion: The optimized formula is pretty encouraging to originate an oral strip that provides ease of administration, fast onset of action with wide acceptance for the pediatric population.

Background: This prospective observational study was done to know the current prescription trend of antimicrobial agents in the post-operative ward. To evaluate the current pattern of antimicrobial agents in the post-operative surgical cases of a tertiary care teaching hospital.

Aims: The present study was aimed to analyse the resistance pattern of culture isolates to antimicrobial agents in the post-operative general surgery cases. To assess the rationale for changing over from one antimicrobial agent to another.

Methods: The study was carried out in collaboration with the Department of General Surgery and Department of Pharmacology during April 2013 to March 2014. All parameters like demographic data, antimicrobials agents prescribed by surgeons, dose, frequency, duration, route, formulation, brand or generic drugs, adverse events were collected in the specially structured case proforma. Descriptive statistics was applied using SPSS version 17.0.

Results: During the study period, 513 patient case records were analysed in which males are higher than females. A total of 816 drugs were used in 484 patients during the study period. 162 were on a single drug, 190 were on two drugs, 42 were on three drugs and 90 were on fixed dose combination. Brand name of the drugs and parenteral route of administration were preferred in the study. Cephalosporins (52.32%) and metronidazole (34.38%) were the most commonly prescribed group of antimicrobials followed by penicillin (0.9%), aminoglycosides (6.58%), quinolones (5.23%), macrolides (0.45%) and tetracycline (0.14%). Totally 135 (27.89%) patients received drugs which are not included in the essential medicine list of WHO and 112 (23.14%) patients received drugs which are not from national EML.

Conclusions: The maximum prescribed antimicrobial agent in the post-operative ward was third generation cephalosporins. Rational prescribing of antibiotics would help avoid polypharmacy and prevent drug resistances. There is a clear need for the development of prescribing guidelines & educational initiatives to encourage the appropriate use of drugs in Surgery. Our study will help in promoting knowledge about essential medicine list among clinicians

Presently, the conduct of acid-base chemical interactions necessitates the use of industrially produced indicators, which are linked to contamination of the environment. This circumstance necessitates the exploration of natural sources for further acid-base indicators. The purpose of this research was to investigate at the acid-base indicating capacity of Synadenium glaucescens extracts. To investigate S. glaucescens' indicating capacity, extracts from the leaves, stems, and root barks were tested for colour change, reversibility, pH range, and effectiveness during titration using strong and weak acids and bases. The findings revealed that only the indicators derived from stem and root bark extracts had indicating capacity, since they were able to change colour due to pH change. The pH range of the two indicators was 2.9 to 12.7, indicating that they were more universal indicators. While in acidity and alkalinity circumstances, both indications could be clearly inverted. At the end points of the titration, the colour changed significantly. The mean titre of the two indicators were ranging from 24.3 ± 0.31 to 25.4 ± 0.75 and 18.9 ± 0.17 to 24.1 ± 0.05, respectively with their colour change from brick red to colourless and orange to colourless, respectively. The end points acquired by stem and root bark indicators correspond to the end points obtained by phenolphthalein and methyl orange, which are standard indicators. As a result, the stem and root bark extracts can be used as an acid-base indicator. More research might be done to make paper indicators and extract the pure compound that is responsible for S. glaucescens' signalling capacity.
