Consequences of Hypoacidity Induced by Proton Pump Inhibitors - a Practical Approach.

BACKGROUND:   Proton pump inhibitors (PPIs) are often a part of drug regimens for many patients, including cancer patients. These drugs are very effective suppressors of gastric acid secretion; a significant increase in the gastric pH is seen with chronic use. This affects absorption of drugs, vitamins, and minerals. PURPOSE: PPIs are associated with many adverse drug reactions; nevertheless, these adverse effects are often neglected in clinical practice. The main aim of this article is to emphasize some of the adverse effects and theoretical mechanisms underlying these adverse reactions, the expected length of therapy before their clinical manifestation, and potential ways of dealing with these adverse reactions. We will focus on hypergastrinemia and rebound hyper-acidity, which occur in patients on long-term therapy with high dose PPIs. Next, we will focus on osteoporosis and hypomagnesemia, adverse effects for which the assumed mechanism is decreased absorption of particular ions from the gastrointestinal tract. Furthermore, clinically significant pharmacokinetic drug interactions at the level of absorption will be analyzed. Tyrosine kinase inhibitors (TKIs) are drugs with limited solubility; this solubility is pH-dependent. Some recommendations seek to ensure optimal absorption with minimal inter-day variability. Tables sum-marizing the optimal relationship between food and TKIs, and (sometimes) the optimal regimen of concomitant PPIs, are included.

Literature Analysis of Escitalopram Adverse Reactions / 医药导报

Objective To investigate the adverse drug reactions (ADRs) induced by escitalopram and precautions. Methods Wanfang,CNKI,Pubmed databases were searched to retrieve information about escitalopram adverse reactions reported in the literature,focusing on analysis of adverse reactions in patients with age,sex,clinical manifestations,involved systems, etc. Results Totally,31 references were collected,and a total of 31 cases included in the review analysis.The adverse reaction rate was equivalent between the male and the female.The adverse reaction occurred a few hours to 6 months after medication,and it involved several organ systems,including the nervous system,circulatory system,endocrine system,alimentary system,urinary system,kinetic system,etc. Conclusion Escitalopram should be used according to the doctor's advice,and its amount should not be arbitrarily added.Regular monitoring of adverse reactions should be performed to ensure rational use of the drug.

Reacción de anafilaxia grave por dipirona sin antecedente de hipersensibilidad. Informe de caso / Severe anaphylaxis reaction from dipyrone without a history of hypersensitivity. Case report

Introduction: The safety of dipyrone has been the object of numerous debates, since severe allergic reactions to it can occur with an estimated incidence of 1 in 5000 parenteral administrations. Clinical findings: We report the case of one patient who, after an infusion with dipyrone, presented coughing, pharynx itch, dyspnea, generalized cyanosis, and decreased consciousness. The diagnosis of anaphylactic shock without a history of hypersensitivity to the medication was made, and despite treatment with orotracheal intubation, adrenaline, hydrocortisone, sodium chloride, and sodium bicarbonate, it was fatal for the patient. Conclusion: Cases of severe hypersensitivity without antecedents can be present in patients, which makes it important to recognize this risk in our patients.

Introducción: La seguridad de la dipirona ha sido objeto de numerosos debates, ya que pueden aparecer reacciones alérgicas graves cuya incidencia estimada es de 1 en 5.000 administraciones parenterales. Hallazgos clínicos: Se reporta un caso de una paciente que luego de una infusión con dipirona presenta tos, prurito faríngeo, disnea, cianosis generalizada y deterioro del estado de conciencia. Se hizo el diagnóstico de shock anafiláctico sin antecedentes previos de hipersensibilidad al medicamento, que a pesar del tratamiento con intubación orotraqueal, adrenalina, hidrocortisona, cloruro de sodio, y bicarbonato de sodio, resultó fatal. Conclusión: pueden presentarse casos de grave hipersensibilidad en pacientes sin antecedentes de ésta, lo que hace importante reconocer este riesgo en nuestros pacientes.

Acatisia inducida por fármacos no psicotrópicos: a propósito de un caso asociado a metoclopramida / Non-psychotropic drugs induced akathisia: a propos of a case associated with metoclopramide use

La metoclopramida es un fármaco antiemético usado en diversas áreas de la práctica médica pero uno de sus efectos adversos más frecuentes y severos es la acatisia. La acatisia es un trastorno del movimiento caracterizado por sensación de intranquilidad y malestar internos acompañados de inquietud motora. Presentamos el caso de un varón de 19 años que desarrolló acatisia aguda luego de la administración de metoclopramida por vía endovenosa. Es importante tener siempre presente en la práctica clínica la posible presentación de acatisia como efecto adverso de la metoclopramida y de otros fármacos no psicotrópicos debido a la frecuencia de su aparición y a su severidad. Realizar un diagnóstico rápido y preciso es necesario para manejar adecuadamente este efecto secundario, además de tomar medidas preventivas para evitar su aparición.

Metoclopramide is an antiemetic drug used in several areas of medical practice but one of its most frequent and severe adverse effects is akathisia. Akathisia is a movement disorder characterized by internal feeling of uneasiness and discomfort accompanied by motor restlessness. We report the case of a 19 year old male who developed acute akathisia after intravenous administration of metoclopramide. It is important in clinical practice to keep in mind the occurrence of akathisia as a posible adverse effect of metoclopramide and other non-psychotropic drugs, because of the frequency of their emergence and severity. It is essential to perform a quick and accurate diagnosis to properly manage this side effect, in addition to taking preventive measures to avoid its occurrence.
