Diuretic Agents

Diuretics are commonly defined as drugs that increase the amount of urine produced by kidney. A precise definition is that diuretics are the agent which augment the renal excretion of sodium and either chloride or bicarbonate primarily, and water excretion secondarily. The term “saluretic” is sometime used to describe a drug that increase the renal excretion of sodium and chloride ion Diuretics are responsible for increase the rate of urine flow, sodium excretion and to maintain the volume and composition of body fluids in a various clinical Disorders. But drug-induced diuresis is very much beneficial in such type of life-threatening disorders like CHF, hypertension, renal failure, Liver cirrhosis and often pregnancy toxaemia.[1] Diuretics relieve pulmonary congestion and peripheral edema. This decreases cardiac workload, oxygen demand and plasma volume, thus decreasing blood pressure. Thus, diuretics play an important role in hypertensive patients.[2] Plant medicine is commonly used in the traditional treatment of some renal diseases, and many plants are reported to possess significant diuretic activity. The diuretic activity of a number of plants used in ethno medicine as diuretic agents has been confirmed in experimental animal. [3]The progress of a polyherbal formulation is a tough job because of the large number of different chemical compounds present in the different medicinal plants.

In the last four decades, the several classes of diuretics, currently available for clinical use, have been the first line option for the therapy of widespread cardiovascular and non-cardiovascular diseases. Diuretic drugs generally exhibit an overall favourable risk/benefit balance. However, they are not devoid of side effects. In particular, all the classes of diuretics cause alteration of potassium homeostasis. <p> In recent years, understanding of the physiological role of the renal outer medullary potassium (ROMK) channels, has shown an intriguing pharmacological target for developing an innovative class of diuretic agents: the ROMK inhibitors. This novel class is expected to promote diuretic activity comparable to (or even higher than) that provided by the most effective drugs used in clinics (such as furosemide), with limited effects on potassium homeostasis. <p> In this review, the physio-pharmacological roles of ROMK channels in the renal function are reported, along with the most representative molecules which have been currently developed as ROMK inhibitors.

VIEKIRA PAK (ritonavir-boosted paritaprevir/ombitasvir and dasabuvir) is an approved treatment for compensated patients with genotype 1 (GT1) chronic hepatitis C virus (HCV) infection. This oral regimen has minimal adverse effects and is well tolerated. Cure rates are 97% in patients infected with HCV GT 1a and 99% in those with HCV GT 1b. We report the first case of life-threatening allergic pneumonitis associated with VIEKIRA PAK. This unexpected serious adverse event occurred in a 68-year-old Chinese female with genotype 1b chronic hepatitis C and Child-Pugh A cirrhosis. One week into treatment with VIEKIRA PAK without ribavirin, she was admitted to hospital with respiratory distress and acute kidney injury requiring intensive care input. She was initially diagnosed with community acquired pneumonia and improved promptly with intravenous antibiotics and supported care. No bacterial or viral pathogens were cultured. Following complete recovery, she recommenced VIEKIRA PAK but represented 5 days later with more rapidly progressive respiratory failure, requiring intubation and ventilation, inotropic support, and haemodialysis. The final diagnosis was drug induced pneumonitis.

Toxic epidermal necrolysis (TEN) is a rare, life-threatening drug-induced skin disease with a mortality rate of approximately 30%. The clinical hallmark of TEN is a marked skin detachment caused by extensive keratinocyte cell death associated with mucosal involvement. The exact pathogenic mechanism of TEN is still uncertain. Recent advances in this field have led to the identification of several factors that might contribute to the induction of excessive apoptosis of keratinocytes. In addition, specific human leukocyte antigen types seem to be associated with certain drugs and the development of TEN. As well-controlled studies are lacking, patients are treated with various immunomodulators (e.g. intravenous immunoglobulin) in addition to the best supportive care.

AbstractCardiac arrhythmias are the most common cause of sudden cardiac death worldwide. Lengthening the ventricular action potential duration (APD) either congenitally or via pathologic or pharmacologic means, predisposes to a life-threatening ventricular arrhythmia, Torsade de Pointes. IKs, a slowly activating K+ current plays a role in action potential repolarization. In this study, we screened a chemical library in silico by docking compounds to the voltage sensing domain (VSD) of the IKs channel. Here we show that C28 specifically shifted IKs VSD activation in ventricle to more negative voltages and reversed drug-induced lengthening of APD. At the same dosage, C28 did not cause significant changes of the normal APD in either ventricle or atrium. This study provides evidence in support of a computational prediction of IKs VSD activation as a potential therapeutic approach for all forms of APD prolongation. This outcome could expand the therapeutic efficacy of a myriad of currently approved drugs that may trigger arrhythmias.Significance statementC28, identified by in silico screening, specifically facilitated voltage dependent activation of a cardiac potassium ion channel, IKs. C28 reversed drug-induced prolongation of action potentials, but minimally affected the normal action potential at the same dosage. This outcome supports a computational prediction of modulating IKs activation as a potential therapy for all forms of action potential prolongation, and could expand therapeutic efficacy of many currently approved drugs that may trigger arrhythmias.

Toxic epidermal necrolysis (TEN) is a rare life-threatening drug-induced mucocutaneous skin disease with a mortality rate of approximately 30%. Nimesulide is a preferential cyclo-oxygenase (COX-2) inhibitor which is frequently used for its antipyretic, anti-inflammatory and analgesic activity. Here, we report a case of nimesulide induced toxic epidermal necrolysis in a 57 years old male patient. This patient was admitted in the hospital with symptoms of epidermal sloughing and fluid filled blisters all over the body following over the counter intake of nimesulide for fever. The drug was promptly stopped, and patient was managed with steroids, antibiotics and other adequate supportive measures. The patient showed significant recovery following stoppage of drug and adequate management. This case highlights the importance of nimesulide and other NSAIDs as possible cause of TEN.

AbstractDrug-induced acute hemolytic anemia led to the discovery of G6PD deficiency. However, most clinical data are from isolated case reports. In 2 clinical trials of antimalarial preparations containing dapsone (4,4′-diaminodiphenylsulfone; 2.5 mg/kg once daily for 3 days), 95 G6PD-deficient hemizygous boys, 24 G6PD-deficient homozygous girls, and 200 girls heterozygous for G6PD deficiency received this agent. In the first 2 groups, there was a maximum decrease in hemoglobin averaging −2.64 g/dL (range −6.70 to +0.30 g/dL), which was significantly greater than for the comparator group receiving artemether-lumefantrine (adjusted difference −1.46 g/dL; 95% confidence interval −1.76, −1.15). Hemoglobin concentrations were decreased by ≥ 40% versus pretreatment in 24/119 (20.2%) of the G6PD-deficient children; 13/119 (10.9%) required blood transfusion. In the heterozygous girls, the mean maximum decrease in hemoglobin was −1.83 g/dL (range +0.90 to −5.20 g/dL); 1 in 200 (0.5%) required blood transfusion. All children eventually recovered. All the G6PD-deficient children had the G6PD A− variant, ie, mutations V68M and N126D. Drug-induced acute hemolytic anemia in G6PD A− subjects can be life-threatening, depending on the nature and dosage of the drug trigger. Therefore, contrary to current perception, in clinical terms the A− type of G6PD deficiency cannot be regarded as mild. This study is registered at http://www.clinicaltrials.gov as NCT00344006 and NCT00371735.

Introduction: CAAs are a rare but potentially life-threatening condition. Commonly defined as localized dilations greater than 1.5 times the adjacent artery, “giant” CAA (GCAA) is a term used to describe CAAs that have progressed to greater than four times the adjacent artery. Case: A 73-year-old male who presented with acute dyspnea was found to have a 4.5cm epicardial mass on computed tomography angiography (CTA) of the chest. Coronary angiography revealed a large partially thrombosed saccular aneurysm of the proximal LCx with diffuse ectasia of the remaining coronary arteries. He underwent percutaneous coronary intervention (PCI) with the placement of a covered stent from the left anterior descending to the left main artery, traversing and effectively occluding the LCx. He tolerated the procedure and was discharged on clopidogrel and apixaban. Discussion: Due to their insidious nature, CAAs are underdiagnosed and progress undetected. Serious complications include aneurysm rupture and fistula formation. CAAs are most commonly caused by atherosclerosis but have been associated with infectious, rheumatologic, and genetic etiologies. Drug-eluting stents are increasingly implicated in CAAs by the mechanism of direct vessel trauma and drug-induced inhibition of smooth muscle proliferation. The optimal management of CAAs remains unclear. Cardiovascular risk reduction and monitoring are recommended. Invasive management is usually reserved for giant or unstable aneurysms. Surgical resection or repair is conventional but percutaneous methods such as coiling and stent occlusion are increasingly utilized. Our patient underwent a successful vessel and aneurysm occlusion with favorable post-PCI outcomes. Conclusion: GCAAs are extremely rare and understudied. Percutaneous management appears effective in the management of GCAAs, but the study of long-term safety and outcomes is required.

Adverse reactions to medication represent a major issue in inpatient psychiatry. This chapter systematically explores the most relevant, concerning, and problematic adverse effects routinely encountered in an inpatient setting. It describes the typical presentation, pathophysiology, incidence, and practical management of these problems. Extrapyramidal side effects including acute dystonia, drug-induced parkinsonism, akathisia, and tardive dyskinesia are considered before the chapter explores the rare but potentially life-threatening condition of neuroleptic malignant syndrome. Other adverse effects common to antipsychotics that are described include hyperprolactinaemia and psychotropic-induced arrhythmias including QTc prolongation. Sexual dysfunction is an under-recognized and undertreated adverse effect common to several classes of psychotropic medication and is also considered. Focusing on antidepressants, the chapter reviews the frequently encountered issue of hyponatraemia as well as serotonin syndrome and selective serotonin reuptake inhibitor-induced bleeding risk. Finally, the chapter addresses perinatal considerations for psychotropic drugs.

ABSTRACT Background: Pancytopenia is a relatively common hematological entity. It is a striking feature of many serious and life-threatening illnesses, ranging from simple drug-induced bone marrow hypoplasia, megaloblastic anemia to fatal bone marrow aplasias and leukemias. The severity of pancytopenia and the underlying pathology determine the management and prognosis. Thus, identification of the correct cause will help in implementing appropriate therapy. Objectives: To study the clinical presentations in pancytopenia due to various causes; and to evaluate hematological parameters, including bone marrow aspiration. Materials and Methods: It was a prospective study, and 104 pancytopenic patients were evaluated clinically, along with hematological parameters and bone marrow aspiration in Hematology Unit, Department of Pathology, JJMMC, Davanagere, during the period of September 2005 to September 2007. Results: Among 104 cases studied, age of patients ranged from 2 to 80 years with a mean age of 41 years, and male predominance. Most of the patients presented with generalized weakness and fever. The commonest physical finding was pallor, followed by splenomegaly and hepatomegaly. Dimorphic anemia was the predominant blood picture. Bone marrow aspiration was conclusive in all cases. The commonest marrow finding was hypercellularity with megaloblastic erythropoiesis. The commonest cause for pancytopenia was megaloblastic anemia (74.04%), followed by aplastic anemia (18.26%). Conclusion: The present study concludes that detailed primary hematological investigations along with bone marrow aspiration in cytopenic patients are helpful for understanding disease process and to diagnose or to rule out the causes of cytopenia. These are also helpful in planning further investigations and management.
