En este estudio prospectivo, no comparativo, se evaluó la eficacia y seguridad de la atorvastatina, una estatina de tercera generación, en el tratamiento de la hipercolesterolemia y su relación con el sexo.

Se incluyó a un total de 40 pacientes con lipoproteínas de baja densidad (cLDL) elevadas. Se consideraron aptos para la inclusión en el estudio los pacientes de ambos sexos, de entre 18 y 80 años de edad, que presentaban una concentración de cLDL > 160 mg/dl si tenían menos de dos factores de riesgo (FR) para enfermedad arterial coronaria (EAC); cLDL > 130 mg/dl si tenían dos o más FR para EAC, y cLDL > 100 mg/dl si padecían EAC. Tras la estabilización con una dieta de 4 semanas, se les administraron 10 mg de atorvastatina por la noche durante 8 semanas.

La concentración de cLDL se redujo en el 38 y el 42% (p < 0,001); el colesterol total (CT) en el 31 y el 32% (p < 0,001); los triglicéridos (TG) en el 23 (p < 0,05) y el 24% (p < 0,01), y las lipoproteínas de alta densidad (cHDL) en el 0 y el 5% (p = NS) en varones y mujeres, respectivamente.

El 77,5% de los pacientes alcanzaron las metas del NCEP para las cLDL. No se encontraron diferencias significativas entre sexos en los parámetros analizados. Ningún paciente abandonó el estudio. Dos pacientes (5%) presentaron flatulencia y dispepsia leve y transitoria. No se registraron elevaciones de las transaminasas o creatincinasas.

En conclusión, la atorvastatina administrada en dosis de 10 mg/día redujo significativamente las concentraciones de cHDL, CT y TG sin modificar las de cHDL. La mayoría de los pacientes alcanzó las metas del NCEP para el cLDL, y el fármaco fue bien tolerado a corto plazo. No se registraron diferencias de eficacia y seguridad entre sexos.

In this prospective, non comparative study, we evaluated the efficacy and safety of atorvastatin, a third generation statin, in the treatment of hypercholesterolemia and its relation with the gender.

We included 40 patients with high low density lipoprotein (cLDL). Inclusion criteria were age between 18 and 80 and levels of cLDL > 160 mg/dl in patients with < 2 risk factors (RF) for coronary arterial disease (CAD); cLDL > 130 if they had two or more RF for CAD and cLDL > 100 mg/dl if they already had CAD. After stabilization with diet during 4 weeks, we administered 10 mg of atorvastatin, at night during 8 weeks.

The cLDL concentrations decreased 38 and 42% (p < 0.001), total cholesterol (TC) 31 and 32% (p < 0.001), triglicerides (TG) 23 (p < 0.05) y 24% (p < 0.01) and high density lipoprotein (cHDL) 0 and 5% in men and women, respectively. Seventy-eight percent of patients reached the NCEP goals for cLDL. We didn't find significant differences between men and women in the analyzed parameters. No patient gave up the study. Only two patients (5%) presented flatulence and dyspepsia that was light and transitory. We didn't observe creatinkinase or transaminase elevations.

In conclusion, atorvastatin administered in single dose of 10 mg decreased the levels of cLDL, TC and TG significantly, without modifying the cHDL. Most of the patients reached the goals of NCEP for cLDL. In this short term study the tolerance was good and we didn't find efficacy or safety differences in relation to the gender.
