ABSTRACT
Background: Renal impairment is the primary cause of mortality and morbid conditions in patients. Inappropriate drug use in patients who are with risk of renal damage causes harmful and deleterious effects. Adjusting doses based on renal function is necessary for renal risk drugs, primarily to avoid adverse reactions of medications. Aim of the present study was to assess the risk of incidence on ADRs with drugs lowering the renal function.Methods: This is a cross-sectional observational study conducted in General Medicine department. 230 Patients constituted the sample in the study. The study was conducted for a period of one year and prescriptions with renal risk drugs were evaluated. Changes in the renal functional tests were compared to the normal range and adverse drug responses were monitored.Results: A total of 230 patients who fulfilled the inclusion criteria were included in the study. The meanage of the study subjects were 50.9±15.2 respectively. 56.39% patients were men and 43.6% were women. Renal risk drugs included in the study are anti-hypertensive, antibiotics, and analgesics. Paracetamol (24.77%) followed by telmisartan (20.85%) are the predominantly prescribed renal risk drugs with high incidence of adverse drug reactions. Causality assessment by Naranjo ADR probability scale showed out of 211 ADRs, 51.6% were possible, 25.59% were doubtful, 21.8% were probable and 0.94% was definite.Conclusions: The current study signifies that patients under high risk of renal damage require continuous monitoring and optimized therapy for better disease management.
ABSTRACT
Introducción: Por prevalencia y trascendencia como factor de riesgo para enfermedad cardiovascular, la hipertensión arterial es una de las enfermedades de mayor importancia en la práctica médica. Este trabajo describe las características clínicas y sociodemográficas de una muestra de pacientes hipertensos con al menos un factor de riesgo cardiovascular adicional, en Argentina, Colombia y Venezuela. Metodología: Es un estudio de corte transversal, con recolección prospectiva de la información en una muestra por conveniencia de pacientes con hipertensión arterial que consultaron a los médicos participantes en cada uno de los tres países. Resultados: Se detectaron diferencias estadísticamente significativas en la distribución de los factores de riesgo cardiovascular (obesidad central, hipertensión arterial no controlada, tabaquismo y dislipidemia) entre las poblaciones de Colombia, Venezuela y Argentina. La población participante estuvo compuesta en su mayoría por mujeres (53,7%), la edad promedio fue de 59,3 +/- DE 13,6 años; 29% de los participantes en el estudio tenían cifras tensionales controladas en el momento de la evaluación. El manejo con dos medicamentos fue el más frecuente en la población total (40,6%) así como en los subgrupos, argentino (47,1%) y colombiano (46,4%), mientras que en la población venezolana el manejo más común fue monoterapia (45%). Los bloqueadores del sistema renina angiotensina II fueron los más utilizados en los tres países. Discusión: Los factores de riesgo cardiovascular susceptibles de ser modificados tienen diferencias geográficas que justifican cambios en su manejo. La hipertensión requiere no solamente manejo farmacológico, sino la intervención sobre estos factores.
Introduction: Due to its high prevalence and its importance as a risk factor for stroke, heart disease, and renal failure, hypertension is one of the most important diseases in common medical practice. The aim of this study was to describe the clinical and demographic characteristics of a sample of hypertensive patients, with at least one additional cardiovascular risk factor, in Argentina, Colombia and Venezuela. Methods: We performed a cross sectional study, with prospective data collection from a convenience sample of patients. Results: we found statistically significant differences in the distribution of cardiovascular risk factors (obesity, non-controlled hypertension, smoking and dyslipidemia) in the population of the different countries. There were slightly more women in our sample (53.7%), the average age was 59.3 (SD 13.6) years. In 29% of the patients hypertension was controlled. The most common practice in the whole sample was the use of two different drugs (40.6%). This was true both in Colombia (46.4%) and in Argentina (47.1%), while in Venezuela the use of monotherapy was more common (45%). Angiotensin II receptor antagonists are the most commonly used drug family in the three countries, either alone or in combination with other therapies. Discussion: Our population shows a poor control of blood pressure. Our patients need a more strict pharmacological therapy together with a strategy to identify and reduce all modifiable cardiovascular risk factors.

BACKGROUND: In Korea before the enforcement of the medical reform in July 2000, it was generally difficult to analyze the conditions of prescriptions in hospitals and clinics. It was true that the circulation process of prescribed medicine was unclear and that there was no support between medical and pharmaceutical industries with the government. Also with the reality of high rate of pharmaceutical expenses among medical costs in Korea, it was necessary to enforce reform of medical and pharmaceutical industries and for our citizens to follow the new reform as well in order to prevent drug abuse and reduce medical costs. This research was to provide basis for future studies on prescription conditions and related factors through compared analysis of before and after the medical reform by analyzing university hospital prescriptions. METHODS: A comparison and analysis of patients, who visited a university hospital for medical treatment, was dpme. There were 23,974 patients in March 2000, and 22,550 patients in March 2001. During these periods 16,870, 12,919 prescriptions were each issued, respectively. RESULTS: There was a total of 46,524 outpatients with 29,789 prescription issued. There were 23,974 outpatients in March 2000 and 22,550 in March 2001 with 16,870 and 12,919 prescriptions, respectively. Among the outpatients, there were 20,769 men (44.6%) and 24,471 women (52.6%) with 13,527 and 16,209 prescriptions, respectively. In comparing the outpatients and prescription issued patients in March 2000 and in March 2001, both men and women showed decrease in the number of prescriptions (P <.001). Also in the ages between 0-15, 16-40 and 41-65, there was a clear evidence of decrease in the number of both outpatients and prescription issued patients (P<0.001). However in the age group of 65 and over there was an increase of 4,453 patients from 3,956 outpatients. The patient analysis in March 2000 and March 2001 excluding the outpatients in emergency, urology, dentistry and radiology shows a decrease in the number of patients in medical departments in general. Also except for the increase of prescription authorized patients in dentistry, urology and family health, it showed a decrease. In general, there was a decrease in the number of cases in the issuance of prescriptions excluding few item changes in the upper 1st to 10th medicine categories in prescribed frequencies. For prescribed medicine categories no vast difference existed. In total medicine categories, there was a decrease in injections from 24.5% to 12.3% and increase of oral medications from 64.5% to 73.8%. Also there was a significant decrease of prescriptions in injections for antibiotics and significant increase of prescription for anti-hypertensive agents such as Angiotensin Converting Enzyme inhibitors. CONCLUSION: This study involved before and after the reform of prescription conditions and obtained related factor information. The results may differ depending on the type of a hospital, patient distribution and local area, but has provided valuable basic research information which did not exist in previous university hospital unit. Hence in relation to the before and after the medical reform, future studies on diseases and on significant changes in elderly patient care, antibiotic usage and in categories of anti-hypertensive agents may be necessary.
