Pharmacovigilance study for SGLT 2 inhibitors- Safety review of real-world data & randomized clinical trials.

PURPOSE: Despite effectiveness of sodium-glucose cotransporter 2 (SGLT 2) inhibitors, concerns have been raised about the potential side effects of these drugs. Thus, a pharmaco-vigilance study was designed that aims to identify any discrepancies between the reported adverse events & assess the safety profile of SGLT2 inhibitors. METHODS: We studied diabetic ketoacidosis (DKA), euglycemic DKA, amputation, urinary tract infection (UTI), mycotic genital infection & hypotension associated with empagliflozin, dapagliflozin, canagliflozin & ertugliflozin in RCTs and reporting databases. WHO's VigiBase, FAERS, EMA's EudraVigilance & DAEN were thoroughly studied to obtain spontaneously reported real-world adverse events. RESULTS: Different SGLT2 inhibitors exhibit varied side effect profiles. Additionally, the findings suggest that adverse events may be more likely to occur in a broader population in the real world than in a highly inclusive clinical trial subset CONCLUSION: Our study provides comparison of the real world reported adverse events to adverse events reported in the clinical trials studying the efficacy of SGLT 2 inhibitors.

Testing and Diagnosis of Clostridioides difficile Infection in Special Scenarios: A Systematic Review.

INTRODUCTION: Clostridioides difficile infection (CDI) is a clinical and laboratory diagnosis. Populations at higher risk of developing disease require a high clinical index of suspicion for laboratory testing to avoid incorrect assumptions of colonization. Common risk factors include recent antibiotic use, elderly (>65 years old), and immunocompromised patients. C. difficile assays should be ordered in an algorithm approach to diagnose an infection rather than colonization. Screening tests are widely available in hospital systems, but novel molecular testing may aid in diagnosis in patients with inconclusive or discordant antigen and toxin test results.  Methods: Data was extracted from PubMed, Scopus, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases based on the keywords "clostridioides difficile", "toxin assay", and "toxic megacolon". The data extracted is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. A total of 27 reports were included in this systematic review. RESULTS: Testing patients with a significant gastrointestinal surgical history, hypogammaglobulinemia, inflammatory bowel disease, intensive care unit, and immunocompromised patients for CDI is highly recommended. Diarrhea in these subsets of patients requires correlation of clinical context and an understanding of assay results to avoid over- and under-treating. CONCLUSION: CDI should be considered in all patients with traditional risk factors. Heightened clinical suspicion of CDI is required in patients with hypogammaglobulinemia, transplant recipients, patients with gastrointestinal surgical history, and inflammatory bowel disease. Testing should be limited to patients with clinical manifestations of CDI to ensure a high pretest probability for test interpretation. Healthcare workers should adhere to testing algorithms to optimize yield in the appropriate clinical context. Diagnostic assays should follow a sequential, stepwise approach to categorize the toxin expression status of the bacteria accurately.

The Chest Wall Mass of Unknown Origin: A Rare Presentation of Esophageal Adenocarcinoma.

A chest wall mass can result from a diversity of underlying disease processes ranging from benign to a site of distant metastasis. The chest wall is a rare site for esophageal adenocarcinoma (EAC) metastasis. Delayed diagnosis can occur when presenting symptoms are not typical of esophageal pathology, and advanced-stage EAC has a high morbidity and low survival rates. Our case demonstrates a rare and unusual presentation of EAC with a poor outcome due to delayed diagnosis.

Diagnostic accuracy of bone scan at different PSA levels in biochemical recurrence of prostate cancer.

OBJECTIVE: To determine the diagnostic accuracy of Bone Scan at different PSA levels for detecting skeletal metastases in men with biochemical recurrence of prostate cancer. METHODS: We conducted a retrospective review of the statewide RIS-PACS to identify 251 men with biochemical recurrence who underwent both a Bone Scan and Ga68 PSMA PET/CT (within 2 months of each other) between September 2019 and December 2022 at a single institution. The Ga68 PSMA PET/CT report was considered to be the reference standard. RESULTS: The median age was 72 years (IQR 67-76) with a median PSA level of 1 ng/ml (IQR 0.25-2.8). Using Ga68 PSMA PET/CT as the reference standard, 68/251 patients (25%) were positive for osseus metastases. Overall sensitivity and specificity of Bone Scan was 51% (95% CI 40-64%) and 99% (95% CI 98-100%) respectively. Using PSA banding, a PSA threshold of 20 ng/ml provided the greatest discriminatory benefit with sensitivity of the Bone Scan below the threshold being 46% (95% CI 33-59%) and above the threshold being 89% (95% CI 68-100%). Specificity remained consistently high both below and above this threshold. CONCLUSION: Bone Scan provides greater diagnostic accuracy for detecting skeletal metastases in biochemical recurrence when the PSA level is above 20 ng/ml. This knowledge is valuable in optimising imaging algorithms in biochemical recurrence, particularly in regions where PSMA PET/CT is less readily available or affordable.

A Sniff Away From Death: A Rare Case of Cocaine-Induced Triple Vessel Coronary Artery Disease in a 41-Year-Old Male Patient.

Cocaine-associated coronary artery disease and ST-segment elevation myocardial infarction (STEMI) have been well described in the literature. However, very few cases of cocaine-induced multivessel coronary artery disease have been reported. We report a very rare case of cocaine-associated triple vessel coronary artery disease in a 41-year-old male patient. The patient underwent urgent catheterization that revealed occlusion of his proximal left anterior descending artery (LAD), mid-circumflex artery, and right coronary artery with angioplasty and stent placement. His hospitalization course was complicated by cardiogenic shock, shock liver, acute renal failure, and sepsis.

Elevated Copeptin Levels Are Associated with Heart Failure Severity and Adverse Outcomes in Children with Cardiomyopathy.

In children with cardiomyopathy, the severity of heart failure (HF) varies. However, copeptin, which is a biomarker of neurohormonal adaptation in heart failure, has not been studied in these patients. In this study, we evaluated the correlation of copeptin level with functional HF grading, B-type natriuretic peptide (BNP), and echocardiography variables in children with cardiomyopathy. Furthermore, we determined if copeptin levels are associated with adverse outcomes, including cardiac arrest, mechanical circulatory support, heart transplant, or death. In forty-two children with cardiomyopathy with a median (IQR) age of 13.1 years (2.5-17.2) and a median follow-up of 2.5 years (2.2-2.7), seven (16.7%) children had at least one adverse outcome. Copeptin levels were highest in the patients with adverse outcomes, followed by the patients without adverse outcomes, and then the healthy children. The copeptin levels in patients showed a strong correlation with their functional HF grading, BNP level, and left ventricular ejection fraction (LVEF). Patients with copeptin levels higher than the median value of 25 pg/mL had a higher likelihood of experiencing adverse outcomes, as revealed by Kaplan-Meier survival analysis (p = 0.024). Copeptin level was an excellent predictor of outcomes, with an area under the curve of 0.861 (95% CI, 0.634-1.089), a sensitivity of 86%, and a specificity of 60% for copeptin level of 25 pg/mL. This predictive value was superior in patients with dilated and restrictive cardiomyopathies (0.97 (CI 0.927-1.036), p < 0.0001, n = 21) than in those with hypertrophic and LV non-compaction cardiomyopathies (0.60 (CI 0.04-1.16), p = 0.7, n = 21).

Statins for Attenuating Cardiotoxicity in Patients Receiving Anthracyclines: A Systematic Review and Meta-Analysis.

Anthracycline chemotherapy causes cardiotoxicity, and the evidence regarding the benefit of concomitant statin use in reducing it remains uncertain. We conducted a meta-analysis of studies using statins and anthracyclines by searching PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov from inception until April 10, 2023. Our analysis included 3 observational studies and 4 RCTs, including the STOP-CA trial released in ACC23. Statin prescription significantly reduced cardiotoxicity in cancer patients receiving anthracycline chemotherapy (OR 0.46, 95% CI: 0.33-0.63; I2: 0%). However, no significant difference was observed in the decline of left ventricular ejection fraction (LVEF) from baseline (MD 4.15, 95% CI: -0.69 to 8.99, I2: 97%). These findings demonstrate the protective effect of concomitant statin prescription.

Pulmonary Atresia with Intact Ventricular Septum: Midterm Outcomes from a Multicenter Cohort.

Contemporary multicenter data regarding midterm outcomes for neonates with pulmonary atresia with intact ventricular septum are lacking. We sought to describe outcomes in a contemporary multicenter cohort, determine factors associated with end-states, and evaluate the effect of right ventricular coronary dependency and coronary atresia on transplant-free survival. Neonates treated during 2009-2019 in 19 United States centers were reviewed. Competing risks analysis was performed to determine cumulative risk of each end-state, and multivariable regression analyses were performed to identify factors associated with each end-state and transplant-free survival. We reviewed 295 patients. Median tricuspid valve Z-score was - 3.06 (25%, 75%: - 4.00, - 1.52). Final end-state was biventricular repair for 45 patients (15.2%), one-and-a half ventricle for 16 (5.4%), Fontan for 75 (25.4%), cardiac transplantation for 29 (9.8%), and death for 54 (18.3%). Seventy-six patients (25.7%) remained in mixed circulation. Cumulative risk estimate of death was 10.9%, 16.1%, 16.9%, and 18.8% at 1, 6 months, 1 year, and 5 years, respectively. Tricuspid valve Z-score was inversely, and coronary atresia positively associated with death or transplantation [odds ratio (OR) = 0.46, (95% confidence interval (CI) = 0.29-0.75, p < 0.001) and OR = 3.75 (95% CI 1.46-9.61, p = 0.011), respectively]. Right ventricular coronary dependency and left coronary atresia had a significant effect on transplant-free survival (log-rank p < 0.001). In a contemporary multicenter cohort of patients with PAIVS, consisting predominantly of patients with moderate-to-severe right ventricular hypoplasia, we observed favorable survival outcomes. Right ventricular coronary dependency and left, but not right, coronary atresia significantly worsens transplant-free survival.

The Role of Allogeneic Stem Cell Transplantation in Multiple Myeloma: A Systematic Review of the Literature.

Multiple myeloma (MM) is an indolent B-cell malignancy, where treatment is aimed at preventing organ dysfunction from light chain accumulation (slowing disease progression) and inducing remission. Allogeneic stem cell transplant (allo-SCT), through graft versus myeloma (GVM) effects, has the potential to induce remission to a potentially curative-like state. In this systematic review, we aimed to understand this relationship to the risks and severity of disease in categorized patients and gain an updated comprehension of the future of allo-SCT in MM treatment. We conducted this review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched the PubMed database to obtain the specified literature with both the use of keywords and Medical Subject Headings (MeSH). A total of 16 relevant articles were included for discussion after the quality appraisal was completed, as appropriate, by either the Cochrane tool or Newcastle-Ottawa checklist. Our review concludes that while allo-SCT may benefit high-risk patients, successful procedures may incorporate a tandem autologous hematopoietic stem cell transplant approach in combination with novel pharmacologic contributions for which there is an observed synergy in the modulation of the immunologic microenvironment. Furthermore, tailored patient selection by evaluating pre-transplant factors including high-risk cytogenetics, age, and pre-salvage International Staging System (ISS) can predict post-transplantation success including non-relapse mortality. Successive research should continue to revise and update treatment options as the evolving therapeutic drug regimens may change over the course of indolent disease.

Type 2 Diabetes and Causes of Sudden Cardiac Death: A Systematic Review.

Type 2 diabetes mellitus has been on the rise in recent years. A major cause of death in the United States is myocardial infarction with underlying coronary artery disease. Impairment of tissue insulin sensitivity in type 2 diabetes is a significant factor for sudden cardiac death. The complex pathophysiology stems from coexisting cardiovascular disease and complications of impaired tissue sensitivity to insulin. Long-term diabetics with underlying kidney disease and those requiring dialysis have systemic inflammation that adds to an increased risk of death. During times of pathological stress, myocardial tissue will express substrates and growth factors that cause conduction disequilibrium and predispose to sudden cardiac death. Diabetes is a modifiable risk factor in the prevention of sudden cardiac arrest. Specific prevention measures aimed towards lifestyle modification and medications are important to prevent diabetes and decrease mortality of future cardiac death. In recent times, drugs that compete with glucose in the proximal convoluted tubule of the nephron have clinical significance in lowering the risk of sudden cardiac arrest.

New Evidence in the Pathogenesis of Celiac Disease and Type 1 Diabetes Mellitus: A Systematic Review.

Celiac disease (CD) and type 1 diabetes mellitus (T1DM) are autoimmune diseases that coexist frequently. These illnesses share a common genetic background. This study aims to review the different pathophysiologic mechanisms that have been studied about the coexistence of CD and T1DM, to contrast them, and to summarize their specific role in these autoimmune diseases. We conducted a systematic review following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) checklist and used the Medical Subject Headings (MeSH) search strategy to obtain relevant articles. We found 585 papers which were reduced to 355 after removing duplicates. Later, the filters and inclusion/exclusion criteria were applied which ended the search with 78 articles. Finally, we reviewed the articles that contained information about the pathogenesis of CD and T1DM, their coexistence, and how the pathogenesis impacts clinical outcomes. The reviewed studies strongly conclude that the presence of human leukocyte antigen (HLA) genes DQ2 and DQ8 are high-risk for developing the coexistence of CD and T1DM. We found that killer immunoglobulin-like receptor (KIR) genes, enterovirus infection in gut cells, and gut microbiota dysbiosis with the predominance of Bacteroides spp. also play a role in the pathogenesis and development of symptoms of CD in patients with the previous diagnosis of T1DM. CD4+ and CD8+ cell levels vary among patients and studies, consequently, more study on this topic is needed.

Unraveling the Association Between Schizophrenia and Substance Use Disorder-Predictors, Mechanisms and Treatment Modifications: A Systematic Review.

Individuals with schizophrenia are particularly vulnerable to substance abuse problems. Comorbidity with substance use disorders (SUDs) frequently results in early death and increased dysfunction observed in schizophrenia. This dual diagnosis can be explained through multiple general mechanisms. Tobacco, alcohol, cannabis, and cocaine are substances widely used by individuals with schizophrenia. This study highlights the predictors, mechanisms responsible for the relationship between substance use disorder and schizophrenia and how it can help with the treatment of both disorders. The publications were rigorously reviewed after being found in multiple databases. The study's inclusion criteria were research published within the last five years, publications written in English, full-text availability, and human studies. A total of ten papers were selected for examination from a total of 9,106 articles found using the search method across several databases. This study follows the rules listed within the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist 2009. The information gathered from these published studies was used to investigate the elements that contribute to the link between schizophrenia and substance abuse. Here, we evaluate a close relationship between schizophrenia and substance use disorders. The articles studied exhibit a bidirectional association between the two disorders in most individuals. From our analysis, the comorbidity between the two disorders is partially due to shared polygenic liability. Individuals with schizophrenia have dysfunctional Mesocorticolimbic brain reward circuits indicating a history of substance use. An underlying genetic vulnerability to schizophrenia may be triggered by extensive cannabis usage at a young age. A combination of psychological and pharmacological interventions for both disorders can significantly improve the outcome.

The Role of Vitamins in Non-Alcoholic Fatty Liver Disease: A Systematic Review.

Non-Alcoholic Fatty Liver Disease (NAFLD) emerged as the most prevalent liver disorder contributing significantly to disease burden worldwide. It manifests as a broad spectrum of hepatic damage with varying severity ranging from less serious steatosis to a more severe Non-Alcoholic Steatohepatitis (NASH), with or without fibrosis, cirrhosis, and hepatocellular carcinoma. Vitamins, on the other hand, are micronutrients that are vital for healthy well-being. Some studies have linked liver diseases with hypovitaminosis; however, there are still some gaps about the basis of their correlation. Hence, this systematic review aims to discuss the role of vitamins in the pathogenesis of NAFLD and explore their hepatoprotective potential that may benefit clinicians in managing this condition. This systematic review searched for studies indexed in the PubMed, PubMed Central, Medline, Google Scholar, and ScienceDirect databases. Inclusion and exclusion criteria were applied, duplicates were removed, and meticulous screening of articles was done systematically. Out of 729 unique studies generated using the search strategy, 17 were finally included after thorough review and quality appraisal.  NAFLD is not simply an outcome of insulin resistance and metabolic derangements; instead, it is a disease with complex underlying pathogenesis. Moreover, vitamin deficiency has been associated with NAFLD development and increased susceptibility to more severe liver damage. Derangement in vitamins correlates to the lipotoxic hepatic environment, altered immune system, unwarranted inflammation, oxidative stress, gene mutations, epigenetic modification, and gut dysbiosis seen in NAFLD. As they influence several pathophysiologic processes in the liver, vitamins A, B3, B6, B9, B12, C, D, and E are promising potential options that can impact NAFLD management. However, more well-designed studies conducted in the human population are still necessary to establish their efficacy and safety as therapeutic agents.

The Correlation Between Parkinson's Disease and Rapid Eye Movement Sleep Behavior Disorder: A Systematic Review.

Parkinson's disease (PD) is a neurodegenerative disease caused due to the destruction of dopaminergic neurons and the deposition of α-synuclein proteins, known as Lewy bodies. Generally, the diagnosis of PD is centered around motor symptoms. However, the early recognition of non-motor symptoms such as autonomic dysfunction, sleep disturbances, and cognitive and psychiatric disturbances are gaining increased attention for the early diagnosis of PD. Rapid eye movement (REM) sleep behavior disorder or REM sleep behavior disorder (RBD) is described as parasomnia, which is a condition of loss of normal muscle atonia causing the person to act out vivid dreams and it has been seen to be associated with the misprocessing of intercellular α-synuclein leading to neurodegenerative diseases such as PD. This review's objective is to highlight the significance of RBD as a prodromal premotor marker for the early detection of PD. We used PubMed as our primary database to search for articles on May 2, 2021, and a total of 1849 articles were found in our initial search using keywords and medical subject heading (MeSH) keywords. Thereafter, we removed the duplicates, applied the inclusion/exclusion criteria, and did a quality appraisal to include 10 articles in this study. We concluded that the recognition and diagnosis of RBD are of paramount importance to detect early PD, and further longitudinal studies and clinical trials are of utmost importance to understand their correlation; also, treatment trials are needed to prevent the phenoconversion of RBD into PD.

Characteristics and Surgical Outcomes of Patients With Late Presentation of Anomalous Left Coronary Artery From the Pulmonary Artery: A Multicenter Study.

We sought to describe the clinical course and outcomes of patients who are diagnosed with anomalous left coronary artery from the pulmonary artery (ALCAPA) after infancy. We conducted a retrospective evaluation of patients who underwent ALCAPA surgery between January 2009 to March 2018 at 21 US centers. Clinical presentation, inpatient management, and postoperative outcomes of patients repaired ≥1 year of age were described. To characterize this cohort, we compared these data to patients repaired before 1 year of age. Of 248 ALCAPA patients, 71 (29%) underwent repair ≥1 year of age. Among this subset, the median age at diagnosis was 8.3 years. Chronic arrhythmia occurred in 7%. Patients had good postoperative recovery of left ventricle (LV) dysfunction (90%) and LV dilation (75%), although a low incidence of recovery of mitral regurgitation (40%). Compared to infants, older patients were more likely to present with cardiac arrest (11% vs 1%) and less likely to have moderate or worse LV dysfunction or mitral regurgitation. Older patients had significantly less postoperative extracorporeal membrane oxygenation use, and shorter ICU and hospital stay. In the older cohort, operative mortality occurred in only 1 patient and no patient died after discharge (median follow-up 2.7 years). Survival of patients who presented with ALCAPA beyond infancy was excellent, although chronic mitral regurgitation and chronic arrhythmia were not uncommon. Patients who underwent ALCAPA repair ≥1 year of age were less likely to present with LV dysfunction but more likely to present with cardiac arrest than younger patients.

Concurrent Use of Calcium Chloride and Arginine Vasopressin Infusions in Pediatric Patients with Acute Cardiocirculatory Failure.

Acute heart failure (AHF) can cause low cardiac output and poor end-organ perfusion. Inotropic agents along with vasodilators can improve organ perfusion. Arginine vasopressin (AVP) and calcium chloride (CaCl) infusions are increasingly being used in low cardiac output states in pediatric AHF. We retrospectively reviewed 77 patients (0-18 years) with AHF admitted between January 2014 and May 2017 who received concurrent AVP and CaCl infusions. Surrogates of cardiac output and organ perfusion included hemodynamic vital signs, laboratory parameters, and urine output (UO). Organ dysfunction and vasopressor inotropic scores were also calculated. Median (IQR) age was 0.88 years (0, 3.75), and median weight was 6.62 kg (3.5, 13.7). Congenital heart disease was present in 70% (46/77) patients. Univentricular physiology was present in 25% (25/77) patients. None of the patients were in the immediate postoperative period. Median durations of AVP and CaCl were 2 days (1, 3) and 3 days (2, 6), respectively. Using Wilcoxon-signed rank test and Bonferroni correction, post hoc comparison showed that at 8 h post infusion, all systolic blood pressure (SBP) and diastolic blood pressure (DBP) results, and UO were greater than those 1 h prior to infusion. Median SBP increased from 79 mm Hg (71, 92) 1 h prior to 97 mm Hg (84, 107) 8 h post. Median DBP increased from 44 mm Hg (35, 52) 1 h prior to 54 mm Hg (44, 62) 8 h post. Heart rate showed a decrease between measurements 1 h prior to infusion and 8 h post, with median scores 146 (127, 162) and 136 (114, 150) beats per minute, respectively. Within first 8 h, median UO continuously increased from 6 mL/h. (0, 25) at 1 h post infusion to 20 mL/h. (2, 62) at 8 h post infusion. Median pediatric logarithmic organ dysfunction scores on days 4 through 7 post infusion were lower compared to day 1; median vasopressor inotropic scores on day 2 through 7 post infusion were lower compared to day 1. Serum lactate level, arterial pH, and base excess all showed favorable trend. Concurrent use of AVP and CaCl infusions may improve surrogates of cardiac output, and intensive care outcomes, and prevent organ dysfunction in children with AHF.

Greater Omental Pancake Tumour due to Metastasis of Ovarian Cancer - A Cadaveric Study.

Cancer of ovary is the one of the common of all gynecological tumors and is the leading cause of death among women. A unique attempt is made to trace masses & its causes found in an abdomen of female cadaver during routine anatomy dissection. The mass was thick, hard and somewhat nodular in the region of greater omentum, After dissecting the pelvic cavity, it was found that both the ovaries were bulky, nodular & hard. Whole abdominal cavity was dissected & found that liver also involved by metastasis. Case suggests that there is the development of metastatic omental mass from grade IV ovarian cancer. Primary human omental adipocytes promote homing, migration and invasion of ovarian cancer cells. Adipokines like interleukin-8 (IL-8) mediate these activities.

A drug utilization study of psychotropic drugs prescribed in the psychiatry outpatient department of a tertiary care hospital.

BACKGROUND: Psychiatric disorders are one of the major causes of morbidity. Development of newer drugs like SSRIs and atypical antipsychotics has altered the treatment paradigms. Various factors like cost of drugs, local paradigms, etc. play a role in the selection of drug therapy and hence, affect the outcome. Keeping this in mind, we conducted a study to delineate the various drugs used in psychiatric disorders, to find discrepancies, if any, between the actual and the ideal prescribing pattern of psychotropic drugs and to conduct a cost analysis. MATERIAL AND METHODS: After our institutional ethics committee approved, a retrospective cross sectional drug utilization study of 600 prescriptions was undertaken. Preparation of the protocol and conduct of the study was as per the WHO - DUS and the STROBE guidelines. RESULTS: Drug use indicators - In 600 prescriptions, 1074 (88.25%) were psychotropic drugs. The utilization from the National and WHO EML was 100% and 90%, respectively. Average number of psychotropic drugs per prescription was 1.79 ± 1.02 (SD). 22.5% of the prescriptions contained psychotropic FDCs. 76.01% of drugs were prescribed by generic name. Percentage of psychotropic drugs prescribed from the hospital drug schedule and psychotropic drugs actually dispensed from the hospital drug store were 73.1% and 62.3%, respectively. Drug utilization pattern in different psychiatric disorders - Most commonly prescribed drugs for schizophrenia, bipolar disorders, depression and anxiety disorders were trifluoperazine + trihexiphenydyl (63.9%), carbamazepine (17.2%), amitriptyline (34.9%), and diazepam (23.8%), respectively. The least commonly prescribed drugs were levosulpiride (1.7%), lithium (1.3%), bupropion (4.7%) and clozapine (1.9%), respectively. The PDD/DDD ratio of three drugs - haloperidol, pimozide and amitriptyline - was equal to one. The cost borne by the hospital was 116, i.e., 65.2% of the total cost. The cost index of clozapine was 11.2. CONCLUSION: Overall, the principles of rational prescribing were followed. The hospital drug schedule should include more SSRIs. The practice of using 1(st) generation/ typical anti-psychotics as the first line was as per current recommendations. Anti-cholinergics should be used only in selected cases of patients on anti-psychotics. The use of diazepam should be curtailed and it should be used for short term only.
