Publication Adverse Drug Reaction (ADR) Monitoring at the Eastern Regional Pharmacovigilance Centre, Nepal(Kathmandu University, 2017) Rauniar, GP; Panday, DRABSTRACT Background Adverse Drug Reaction is any unintended drug consequence. It is often preventable. In developed countries, it is among the top ten leading causes of morbidity and mortality. However, it’s monitoring is largely unexplored in developing countries like Nepal. Objective To identify and characterize the pattern of Adverse Drug Reactions at BP Koirala Instittue of Health Science (BPKIHS), the Eastern Regional Pharmacovigilance Centre of Nepal. Method It was an observational study among the patients presented to different Clinical Departments of BPKIHS. Study duration was between July 2012 to July 2015. Adverse Drug Reactions were documented in a structured questionnaire and analysis done, in the department of Clinical Pharmacology and Therapeutics, using Microsoft 2013 Excel. Result There were total 150 Adverse Drug Reactions documented mostly in the age range of 19-40 years (61.4%) with female preponderance (56.7%). Maximum Adverse Drug Reactions were collected from Psychiatry (60.7%) followed by Dental surgery (17.3%) and Internal Medicine (10.7%). Most frequent Adverse Drug Reactions were seen with drugs primarily affecting CNS (64.7%), followed by steroids (18.0%) and Antimicrobial drugs (12.0%). Among CNS drugs, Antidepressants (93.6%) accounted for most documentation. Weight gain (20.1%), Fatigue (12.4%), Rash (8.1%), Acid peptic disorder (7.7%), Headache (7.2%) and Puffiness of face (7.2%) were the most frequently encountered Adverse Drug Reactions. Conclusion Most reported Adverse Drug Reactions were from young (18-40) female presented to the department of Psychiatry. Weight gain was the most common side effect.

In BP Koirala Institute of Health Sciences (BPKIHS), each year there are around 1000 cases of UTIs. Antibiotic is empirically started after sending culture/sensitivity (c/s) with intention to change antibiotic if c/s demands. Objective To see the antimicrobial prescribing pattern and c/s pattern of UTI inpatients of BPKIHS together with their socio-demographic and laboratory profile. Method It was a Record-Based Retrospective Descriptive Study of past one-year. All available inpatient-records from Medical-Record Section were extensively searched for the keyword “UTI” diagnosis. The relevant data were entered in Microsoft Excel-sheet and analyzed with IBM SPSS 21. Ethical clearance was obtained from the IRC before study. Result There were 86 cases from four different wards. There was slight female preponderance (51.16%). Fifty-five (63.95%) cases were complicated. Fever (75.51%) was the most common symptom. Only 20% were tachycardic but 90% were tachypnic. Leucocytosis (59.26%), urine albumin within 30-100 mg/dl (33.85%) and >5 Urine WBC/hpf (80.26%) were seen. Ceftiaxone (53.16%) was the most commonly prescribed empirical antibiotic, followed by Cefixime (6.32%). Fourteen (16.27%) cases were culture positive. E. coli was the most (78.57%) common pathogen grown. In culture sensitivity study, Amikacin (42.85%) was the most sensitive antibiotic. Conclusion Eighty-six UTI inpatients were identified last year. Fever and Tachypnoea were very common. Leucocytosis, 1+ proteinuria and urine WBC>5/hpf were frequently seen. Ceftriaxone was the most common antibiotic prescribed. E. coli was the most common pathogen grown and Amikacin was the most sensitive antibiotic. KEY WORDS Antimicrobial, Inpatients, Urinary tract infectionPublication Antimicrobial utilization pattern in out patient services of ENT department of tertiary care hospital of Eastern Nepal(Kathmandu University, 2005) Das, BP; Sethi, A; Rauniar, GP; Sharma, SKObjective The objective of this study was to monitor the antimicrobial utilization in ENT out patient services in a tertiary care hospital of Nepal. Materials & Methods A total of 191 prescriptions were randomly audited at varying time interval from the department of ENT in the year2003. The data was collected in customized Performa in the form of antibacterial audit questionnaires. It also contained Patient particulars, diagnosis, investigations, drug details and information from the prescriber regarding the indication for prescribing antimicrobial agent, suspecting organism underlying infection, duration of therapy and details of any concomitant medications. Results The incidence of use of antimicrobial agents (AMA) in 191 prescriptions was analyzed from the enrolled prescriptions, a total of 218 antimicrobials i.e.1.4 antimicrobial agent per patient were prescribed. .The AMAs were indicated therapeutically in 73.29% of patients & 19.37% patients for prophylaxis. The AMAs were advised for more than 72 hours for prophylaxis in 86.48%. In the concomitant medications antihistaminic were prescribed in 32.62% and NSAIDS in 21.98% cases. Most of patients reported with upper respiratory tract infections (URTI- 32.56%), Chronic Suppurative otitis Media (CSOM-18.3%), sinusitis (6.28%), tonsillitis (5.75%),. Pharyngitis (3.66%), Acute Suppurative Otitis Media (ASOM-2.61%) and others. The diagnosis was established clinically in 42.40% and confirmative in 35.60%. In 21.46% the diagnosis was not disclosed. Out of 191 patients, culture sensitivity tests were performed for only 31 patients and 13 patients depicted a positive culture sensitivity tests. The common microbes isolated from the culture were staphylococcus aureus (69.2%). Streptococcus (7.7%), Enterobacteriacae (7.7%), Pseudomonas auroginosa (7.7%) & psendomanas mirabilis (7.7%). Clinically suspected organism were mentioned in only 32 prescriptions and most prescriber presumed the infections due to staphylococci & pseudomonas (43.75%), streptococci (21.8%),Gram negative organisms (12.5%) and H influenza (9.3%).The use of a single drug was abundant (89.52%), two drugs (9.94%), and three drugs (0.52% )prescriptions. Ciprofloxacin (23.85%) was preferred, followed by amoxycillin (20.06%), combination of ampicillin + cloxacillin( 9.17%), doxycyclin (5.96%). Erythromycin (4.58%) and cotimoxazole (4.58%). Expensive drugs i.e azithromycin (2.75%), roxithromycin (1.37%) and cephalosporins (3.21%) were also prescribed. The causative microbes were sensitive to amoxycillin (53.84%), cloxacillin (53.84%) ciprofloxacin (46.15%), gentamicin (46.15%), and cephalosporin (46.15%). But resistant to erythromycin, tetracycline, cotrimoxazole and norfloxacin) Conclusions-Majority of patients were prescribed drugs irrationally with misleading indications without confirming the bacteriological culture and sensitivity.

Feedback intervention on drug prescribing habits and face to face educational intervention of prescription audit would be effective in rationalizing prescribing practices. Objective To measure the impact of educational feedback intervention on the prescribing behavior of dental surgeons. Methods Prospective audit of twelve hundred outpatients prescriptions in dental OPD at BPKIHS of those dental surgeon who attended the educational intervention session was collected randomly by trained persons on customized data collection sheet before and after educational intervention. Results A total 1200 prescription were collected, 300 before and 300 after intervention period at the internal of one month, three months and six months. Majority of the prescriptions (39.33%) contained four drugs but after intervention, prescriptions contained mostly one drug, 73% in first month, 78.67% in third month and 65.34% in six month. Mean number of drugs per prescription after intervention were decreased. There was increased number of generic names of drugs after intervention. Amoxicillin, Metronidazole, Chlorhexidine, Povidone iodine gargle, Nimesulide, Ibuprofen, Ibuprofen + paracetamol, and Paracetamol were most commonly prescribed by dental prescribers before and after intervention. Selection of antimicrobial was done on empirical basis which was correct because Amoxicillin concentration reaches effectively in gingival crevicular fluid and Metronidazole covered effectively against anaerobic bacteria were found in orodental infection. The uses of topical anti-infective preparation as irrigants of choice that can kill majority of micro-organisms found is root canal and dental tubules and minimize systemic use of antimicrobials. Nimesulide prescribing needs to be rationalized. Conclusion Feedback educational intervention of prescription audit is effective to improve their prescribing behaviors and rationalize drug utilization pattern for the benefit of the patients. KEY WORDS Dental prescriber, drug utilization, feedback educational interventionPublication Evaluation of anxiolytic activity of tensarin in mice(Kathmandu University, 2007) Rauniar, GP; Deo, S; Bhattacharya, SKIntroduction: Anxiolytic drugs are amongst the most frequently prescribed drugs. Available anxiolytic agents are associated with several limitations. Several indigenous drugs are being evaluated but none has been proved to be effective. Objectives: Aim of the present study is to evaluate the anxiolytic effect of Tensarin. Material and method: The behavioural tests were conducted with single dose schedule and multiple seven-dose schedules of Tensarin 50mg/kg, 100mg/kg and 200mg/kg in comparison with Diazepam 1mg/kg in mice using open field test, activity-monitoring and passive avoidance test. There were eight treatment groups in each treatment schedule. Each group consisted of ten animals of either sex. The data obtained were analyzed using non- parametric test and P-value of less than 0.05 was considered to be statistically significant. Results: Multiple doses produced anxiolytic effect as indicated by an increase in rearing, number of crossing and the time spent by the animals in Central Square. It was also seen that there was significant decrease in step down latency, increase in step down error and time spent by animal in shock zone, these effects were not observed in single dose study. Conclusion: Tensarin shows a dose dependent anxiolytic effect but further studies are needed to find out the exact mechanism of action of the formulation.

It may lead to wastage of resources, emergence of antimicrobial resistance, adverse drug reactions and prolonged suffering. Little has been reported on the extent of self-medication practiced in medical students in Nepal. Objective To study the pattern, reason and perception of self-medication among undergraduate students. Method A cross-sectional study was conducted among all undergraduate students at BP Koirala Institute of Health Sciences, Dharan, Nepal between April and May, 2015. After obtaining ethical clearance, pre-validated questionnaire was used to collect data. The date were analyzed and presented as frequency and percentage using SPSS version 11.5. Result Total of 520 students participated in the study with a mean age of 21.2±1.7 years. Prevalence of self-medication was found to be 48.3%. Most common cause for self-medication was common cold (53.3%). Nonsteroidal anti-inflammatory drugs (78.9%) were the most commonly used medicine for self-medication. The students commonly approached their seniors (50.2%) for the drug information. The most common adverse drug reaction experienced by the students was drowsiness (50.9%). Approximately one third of the students (33.2%) used to prescribe medicines to others. More than half of the students (53.8%) opined that self-medication is a part of self-care. Around one-fifth of the students (21.5%) students opined that self- medication is recommended by WHO. Conclusion Self-medication is commonly practiced by undergraduate students. Nearly one third of the students also prescribe medicines to others. Nonsteroidal anti-inflammatory drugs are the most commonly used medicine as self-medication. The students need to be educated regarding appropriate safe-medication. KEY WORDS Antibiotics, medical students, non-steroidal anti-inflammatory drugs, self-medicationPublication Recent advancement in drug delivery system(Kathmandu university, 2008) Paudel, KR; Rauniar, GP; Bhattacharya, SK; Das, BPAbstract Ease of drug administration, safety, affordability and efficacy are the major concerns in pharmacotherapy leading to exploration of better drug delivery systems. Liposomes are lyotropic liquid crystals composed mainly of ampiphilic bilayers and these are more frequently used as drug carriers. Liposomes help reduce the toxicity and deliver the drug to the target tissue. So far, liposomes have been the most intensively studied lipid-based delivery system. In liposomes, a hydrophilic drug can be trapped in aqueous interior or channels between successive phospholipids bilayers whereas a hydrophobic drug can reside with the bilayer itself. The non-toxic and nonimmunogenic bilayers dissipate allowing the diffusion of the drug into the tissues. Attachment of polyethyl glycol to the surface of liposome (known as stealth liposome) aids in the better targeting of the drug to the tissues. Pegylated proteins and polymers of lactic and glycolic acids have been well studied as drug carriers and found to be resistant to phagocytosis and complement activation. Newer DNA based strategies including DNA vaccination and antisense oligonucleotides and immunomodulation show good results for new therapeutic systems. Though the DNA based therapeutic systems have high selectivity and specificity with few adverse effects, these systems are so far restricted to animal models and clinical trials.

The genetic predisposition plays a key role in the genesis of epilepsy. The already existing antiepileptic drugs (AEDs) provide effective control of majority of patents with different types of seizures. In some refractory cases and in those patients who can not tolerate the conventional AEDs, there is an urgent need to provide relief by controlling the seizures adequately. Various newer approaches in the rational management of seizures have been evolved during the recent years, based on different mechanisms of action and side effects profile. A brief account of these newer treatment modalities have been incorporated in this review in order to enlighten the readers about the possible beneficial effect of this regimen vis a vis the limitations of such use. Keywords: Neurotransmitter imbalance, defective gene, newer antiepileptic drugs, plasma levels, newer approaches.Publication Vagus nerve stimulation: A novel approach for prevention and control of refractory seizures(Kathmandu University, 2007) Bhattacharya, SK; Das, BP; Rauniar, GP; Sangraula, HIn order to understand the brain function and to treat various neuropsychiatric illnesses including epilepsy, continued search and discovery of newer antiepileptic drugs has failed to revolutionize the approach in the management of this complex disorder. Moreover, in close to 30% of epilepsy patients, the seizure control is either not satisfactory or it is intractable to pharmacotherapy. Amongst the non-pharmacological treatment options for refractory epilepsy, vagus nerve stimulation occupies a unique position as an adjunctive treatment in prevention and control of partial-onset seizures in adults and adolescents older than 12 years. Though the precise mode of action of VNS is still debatable an honest attempt has been mode here to review all possible literatures available on VNS to establish its role in the management of this complex disorder.
