Diclofenaco y riesgo cardiovascular



Widely Used Diclofenac Associated With Increased Risk for Cardiovascular Events


Abstract
Background
Certain non-steroidal anti-inflammatory drugs (NSAIDs) (e.g., rofecoxib [Vioxx]) increase the risk of heart attack and stroke and should be avoided in patients at high risk of cardiovascular events. Rates of cardiovascular disease are high and rising in many low- and middle-income countries. We studied the extent to which evidence on cardiovascular risk with NSAIDs has translated into guidance and sales in 15 countries.
Methods and Findings
Data on the relative risk (RR) of cardiovascular events with individual NSAIDs were derived from meta-analyses of randomised trials and controlled observational studies. Listing of individual NSAIDs on Essential Medicines Lists (EMLs) was obtained from the World Health Organization. NSAID sales or prescription data for 15 low-, middle-, and high-income countries were obtained from Intercontinental Medical Statistics Health (IMS Health) or national prescription pricing audit (in the case of England and Canada). Three drugs (rofecoxib, diclofenac, etoricoxib) ranked consistently highest in terms of cardiovascular risk compared with nonuse. Naproxen was associated with a low risk. Diclofenac was listed on 74 national EMLs, naproxen on just 27. Rofecoxib use was not documented in any country. Diclofenac and etoricoxib accounted for one-third of total NSAID usage across the 15 countries (median 33.2%, range 14.7–58.7%). This proportion did not vary between low- and high-income countries. Diclofenac was by far the most commonly used NSAID, with a market share close to that of the next three most popular drugs combined. Naproxen had an average market share of less than 10%.
Conclusions
Listing of NSAIDs on national EMLs should take account of cardiovascular risk, with preference given to low risk drugs. Diclofenac has a risk very similar to rofecoxib, which was withdrawn from worldwide markets owing to cardiovascular toxicity. Diclofenac should be removed from EMLs.

Mi comentario
Desde hace años se han publicado artículos del riesgo cardiovascular de los AINES y este artículo nos viene a demostrar lo que hemos estado leyendo.  Creo que debemos de reevaluar nuestra manera de tratar el dolor y la inflamación y debemosde usar los medicamentos con menor RCV, tales como naproxeno.  Para el dolor hay que seguir la tabla del tratamiento del dolor de OMS:

Estoy totalmente de acuerdo con regular y normar el uso de medicamentos de venta libre como en el caso del diclofenaco, ya que como hacertadamente demuestra el estudio conlleva a los riesgos cardiovasculares de los cuales la propaganda y los comerciales no hacen referencia, asi mismo debemos de ser conciente en los usos en pacientes que si lo ameriten, en pocas palabras individualizar el paciente con el medicamento que prescribimos.
