ABSTRACT

OBJECTIVE: To evaluate the efficacy and tolerability of aceclofenac, 200 mg/day, and paracetamol, 3000 mg/day, in the treatment of osteoarthritis (OA) of the knee. METHODS: This was a double-blind, parallel-group, multicentre clinical trial involving patients with symptomatic OA of the knee, conducted in Spain. Patients were randomly allocated to aceclofenac 100 mg twice daily (n=82) or paracetamol 1000 mg three times daily (n=86). Patients were assessed at baseline and 6 weeks. Primary efficacy measures were severity of pain (visual analogue scale, VAS), Lequesne OA knee index, and patient's and physician's global assessment of disease activity. Severity of knee pain at rest or walking, stiffness, knee swelling and tenderness, and assessment of health-related quality of life (Health Assessment Questionnaire, Western Ontario and McMaster Universities Osteoarthritis Index, and Short Form 36) were included as secondary endpoints. RESULTS: Both treatment groups showed significant improvement compared with their baseline values in the four primary endpoints. Mean between-treatment differences favoured aceclofenac over paracetamol on pain (VAS, 7.64 mm [95% confidence interval (CI), 0.44-14.85 mm]), Lequesne OA index (1.41 [95% CI, 0.45-2.36]), and patient's (0.33 [95% CI, 0.06-0.61]) and physician's (0.23 [95% CI, 0.01-0.47]) global assessments. Adverse events were similar for both drugs (paracetamol, 29% patients vs aceclofenac, 32%; P=0.71). Four patients withdrew in each group due to adverse events. Patients tended to prefer aceclofenac to paracetamol (P=0.001), and more treated with paracetamol withdrew from the study due to lack of efficacy (n=8 vs n=1, P=0.035, for paracetamol and aceclofenac, respectively). CONCLUSION: At 6 weeks, patients with symptomatic OA of the knee showed a greater improvement in pain and functional capacity with aceclofenac than paracetamol with no difference in tolerability.

ABSTRACT

PURPOSE: To investigate the behaviour of primary care (PC) physicians on inadequate hypertension control. DESIGN: Cross-sectional and multicentric study. SETTING: PC clinics in the whole of Spain. PATIENTS: Patients > or =18 years old who followed pharmacological antihypertensive treatment since at least 3 months before, selected by a consecutive sampling. MEASUREMENTS: Blood pressure measured by family doctors. The therapeutic diagram used before and after the visit was registered, and in those cases in which some kind of modification was adopted, the reasons why. RESULTS: 12,754 hypertensive patients were included. The average age was 63.3+/-10.9 years (57.3% women). A 65% lived in urban areas and the 35% in semi-urban o rural areas. The 63.9% (95% confidence interval, 63.1%-64.8%) showed a bad control of hypertension. The majority of the patients followed a therapeutic regimen of monotherapy (56%) being the ACE inhibitors the most prescribed drug (34.8%), followed by the calcium antagonist (21.3%), and angiotensin II antagonists (17.4%). The percentage of patients with inadequate control of the blood pressure, in which the therapeutic behaviour was modified was 18.3% (95% confidence interval, 17.5%-19.1%) (a change of drug in 47%, association in 34.7% and an increase in the dose in 18.3%). The main reasons for which the therapeutic behaviour was modified was because no drug efficacy (63.7%) and the presence of adverse events (5.5%). The price of the therapy originated 1.2% of the modifications. CONCLUSIONS: PC physicians behaviour was conservative in uncontrolled hypertension cases. Amongst the doctors who modified their behaviour, by inadequate blood pressure control, the change of drug was the decision most adopted.

ABSTRACT

Objetivos. Conocer la conducta del médico de atención primaria (AP) ante la falta de control de la hipertensión arterial. Diseño. Estudio descriptivo, multicéntrico. Emplazamiento. Consultas de AP del conjunto de España. Participantes. Hipertensos mayores de 18 años que seguían tratamiento farmacológico antihipertensivo desde al menos 3 meses antes, reclutados mediante muestreo no probabilístico de casos consecutivos. Mediciones principales. Presión arterial medida por los médicos de familia. Se registró el esquema terapéutico utilizado antes y después de la visita, y en los casos en los cuales se adoptó alguna modificación, los motivos de ésta. Resultados. Se incluyó a 12.754 pacientes hipertensos. La edad media fue de 63,3 ± 10,9 años (un 57,3% mujeres). El 65% habitaba en medio urbano y el 35% en medio semiurbano o rural. El 63,9% (intervalo de confianza del 95%, 63,1-64,8%) presentó mal control de la hipertensión arterial. La mayoría de los pacientes seguía un régimen terapéutico de monoterapia (56%). Los fármacos más prescritos fueron los inhibidores de la enzima de conversión de la angiotensina (34,8%), seguidos de los antagonistas del calcio (21,3%) y los antagonistas de los receptores de la angiotensina (17,4%). El porcentaje de pacientes con inadecuado control de la presión arterial en quienes se modificó la pauta terapéutica fue del 18,3% (intervalo de confianza del 95%, 17,5-19,1%) (cambio de fármaco en un 47%, asociación en el 34,7% y aumento de dosis en un 18,3%). Los principales motivos por los que se modificó la pauta terapéutica fueron la falta de eficacia del tratamiento (63,7%) y la presencia de acontecimientos adversos (5,5%). El precio del medicamento originó el 1,2% de las modificaciones en la pauta. Conclusiones. La conducta terapéutica del médico de AP fue conservadora en los hipertensos no controlados. En los médicos que modificaron su conducta ante el mal control, el cambio de fármaco fue la decisión más adoptada

ABSTRACT

Objetivos. Candesartán es un fármaco antihipertensivo, antagonista de los receptores AT1 de la angiotensina II (ARA) que ha demostrado una alta eficacia y seguridad en ensayos clínicos. El presente estudio pretende evaluar la efectividad y tolerabilidad de candesartán en condiciones de práctica clínica real y el efecto sobre la presión arterial (PA) y la presión de pulso (PP) en pacientes con hipertensión arterial (HTA) esencial leve-moderada no controlada. Material y métodos. Estudio prospectivo observacional realizado en una cohorte de 9.013 pacientes afectos de HTA esencial (54 por ciento mujeres), con una edad media de 60,7 ñ 11,5 años, en tratamiento con candesartán y un seguimiento de 12 semanas. Todos los pacientes fueron tratados en régimen ambulatorio y recibieron candesartán durante 12 semanas. Las variables de eficacia analizadas fueron el descenso absoluto de la PA y PP y el porcentaje de pacientes que alcanzaron cifras inferiores a 140/90 mmHg. La variable de seguridad fue la tasa de reacciones adversas aparecidas durante el tratamiento con candesartán. Resultados. Después de 12 semanas de tratamiento candesartán produjo un descenso significativo (p < 0,001) de la PAS (23,9 mmHg), de la PAD (14,3 mmHg) y de la PP (9,7 mmHg). Este último parámetro descendió de forma significativa más marcada en las mujeres respecto a los varones (10,4 mmHg frente a 9,3 mmHg; p < 0,05), en los pacientes diabéticos respecto a los no diabéticos (10,7 mmHg frente a 9,5 mmHg; p<0,05) y en aquellos con factores asociados de riesgo cardiovascular respecto a los que no tenían (10,1 mmHg frente a 9,4 mmHg; p<0,05). La tasa de control estricto (cifras inferiores a 140/90 mmHg) con candesartán fue del 30,4 por ciento. En los pacientes con HTA sistólica aislada los descensos de PA observados después del tratamiento con candesartán fueron de 20,5 mmHg para la PAS, de 3 mmHg para la PAD y de 17,5 mmHg para la PP. La tasa de reacciones adversas al fármaco fue del 2,1 por ciento. Conclusiones. Candesartán es un fármaco efectivo y bien tolerado capaz de reducir la PP, especialmente en los pacientes diabéticos, con factores asociados de riesgo vascular o con HTA sistólica aislada. En estos últimos además la modificación de la PAD es insignificante, lo que otorgaría al fármaco un mejor perfil de seguridad (AU)
