ABSTRACT

Objetivo: Comparar efectos hipotrigliceridemiantes entre gemfibrozilo y aceite de Sacha Inchi en Rattus rattus var albinus. Materiales y Método: Se utilizaron 36 especímenes, los cuales fueron divididos al azar en 2 grupos experimentales (GE1 y GE2) y un grupo control (GC). Fueron sometidos a etapa de acondicionamiento por 2 semanas, luego alimentación rica en grasa por 2 semanas; posteriormente se administró aceite de Sacha Inchi y gemfibrozilo a GE1 y GE2, respectivamente. Se midieron los niveles de triglicéridos séricos en etapa basal, post-alimentación rica en grasa y tratamiento a una y dos semanas. Resultados: Disminución de niveles de triglicéridos séricos en GE1, GE2 y GC a dos semanas de tratamiento, de 45,57 %; 44,83 % y 27,24 % respectivamente. Diferencia de medias para GE1 y GE2 a una y dos semanas de tratamiento en relación a medias de valores postalimentación rica en grasa, fue muy altamente significativa; y diferencia entre grupos experimentales y GC a dos semanas de tratamiento fue significativa, con homogeneidad entre GE1 y GE2 (p=0,600). Conclusión: El aceite de Sacha Inchi demostró efectos hipotrigliceridemiantes, con eficacia similar al gemfibrozilo, en Rattus rattus var albinus, a una y dos semanas de tratamiento.


Objective: To compare the triglyceride lowering effect of gemfibrozil against that of Sacha Inchi oil in Rattus rattus var albinus. Materials and Methods: Thirty-six animals were used. They were divided in two experimental groups (GE1 and GE2) and a control group (CG). The animals underwent a conditioning stage for two weeks, afterwards they were fed with fat-rich meals; and later, the animals from the two experimental groups received Sacha Inchi oil and gemfibrozil, respectively. Serum triglyceride levels were measured at the beginning of the trial, after receiving the fat-rich food and after one and two weeks receiving the test drugs. Results: Serum triglyceride levels had 45,57%, 44,83%, and 27,24% reductions in GE1, GE2 and CG groups, respectively, after two weeks receiving the test drugs. The mean difference of triglyceride values in GE1 and GE2 groups after one and two weeks receiving the test drugs was highly significant compared with values measured after receiving the fat-rich meals; and the difference between the experimental groups and the control group after two weeks using the test drugs was also significant, and the results obtained in the GE1 and GE2 groups were homogeneous (p= 0,600). Conclusion: Sacha Inchi oil showed a triglyceride lowering effect which was similar inefficacy to that of gemfibrozil in Rattus rattus var albinus, after one and two weeks using the test products.

ABSTRACT

Monoterapia para o tratamento das dislipidemias é frequentemente insuficiente para o alcance das metas recomendadas pelas diretrizes. Entretanto, nos últimos anos, o uso de terapia combinada tem se apresentado como uma nova opção em muitos casos. Uma revisão de 36 estudos envolvendo a combinação de estatinas com fibratos apresentou 29 casos de rabdomiólise e uma prevalência geral de miopatia de 0,12 por cento. A combinação de estatinas com o genfibrozil parece causar mais rabdomiólise que com os fibratos de nova geração (especialmente quando comparado com fenofibrato ou bezafibrato). Idade avançada, diabetes, mulheres, medicações concomitantes, disfunção renal, consumo excessivo de álcool, exercícios, traumatismos e cirurgias estão também associados com maior risco de efeitos adversos.

ABSTRACT

Se evaluó el efecto de 40 mg de Lovastatina en comparación con 900 mg de Gemfibrozil en 32 pacientes con hiper-colesterolemia primaria e hipertriglicidemia, después de un período de dieta tipo I de acuerdo a la Sociedad Americana de Cardiologia. En ambos grupos se produjo un descenso en los niveles de colesterol, siendo más pronunciado en el grupo que recibió Lovastatina con un descenso promedio de 92 mg/dl Vs. 58,5 mg/dl de Gemfibrozil. En relación a los triglicéridos los descensos fueron de 99 mg/dl para el grupo de Lovastatina y de 149,9 mg/dl en el grupo de Gemfibrozil. No se reportaron efectos secundarios en el grupo que recibió Lovastatina, el grupo con Gemfibrozil (5/16) en 31 por ciento presentaron efectos en el área gastrointestinal

ABSTRACT

Con el fin de evaluar el uso racional de gemfibrozilo, lovastatina y colestiramina, se llevó a cabo un estudio de utilización de medicamentos por vía prescripción-indicación referido al protocolo Institucional sobre el manejo de las dislipidemias con medicamentos tras un período de dieta. El criterio fundamental para valorar la racionalidad de la indicación fue gemfibrozilo para hipertrigliceridemia pura o hiperlipidemia mixta, y colestiramina o lovastatina para hipercolesterolemia pura, a partir de las boletas del protocolo de tratamiento recibidas en el curso de 12 meses. El análisis incluyó n=3539 casos, y mostró el uso racional de los fármacos hipolipidemiantes en más del 87 por ciento de las prescripciones registradas; el uso irracional mostró diversas causas. Se incluye que existe un predominante uso racional de hipolipidemiantes y que la protocolización terapéutica tuvo un impacto positivo en el perfil de prescripción.

ABSTRACT

Effectiveness of repeated blood donation in lowering blood lipids has been studied. Ten patients of hyperlipidaemia who donated blood 300 ml every month for 3 months and received gemfibrozil 1200 mg/day (Group B) had nearly 2 fold greater fall in serum total cholesterol, LDL and triglyceride levels in comparison to 17 patients of group A who were treated with gemfibrozil alone in similar dose for the same period. HDL level remained almost unchanged. Thus, a non-pharmacological way of treating hyperlipidaemia has emerged from this study. Moreover donated blood will be available as by-product for use by others. This method may be especially suitable in obese persons.

ABSTRACT

Teniendo en cuenta las múltiples evidencias con resultados satisfactorios con Gemfibrozil por varios autores en otras latitudes y, considerando que existen algunos pacientes que, debido a varios factores, no cumplen las medidas higiénico-dietéticas adecuadamente, se realizó un estudio en 27 pacientes con Hiperlipemias tipo IIb y tipo IV de Fredrickson. Además de insistirles en las medidas higiénico-dietéticas conocidas, se le inició tratamiento con Gemfibrozil a razón de 600 mgrs. dos veces al día. Se elaboró un formato con toda la información pertinente. Se determinó el perfil lipídico previo y luego a los (3) meses de tratamiento. En la mayoría de los pacientes hubo cambios favorables significativos en sus perfiles lipídicos, siendo estos cambios más notables en los pacientes con Hiperlipidemias tipo IIb. No se observaron efectos colaterales relacionados con la droga que obligara a suspender la misma. Podemos concluir que, además de las medidas higiénico-dietéticas como medida de intervención primaria en pacientes con Hiperlipidemia, Gemfibrozil constituye un elemento de primer órden a considerar en el manejo de estos pacientes, sobre todo si además presentan otros factores de riesgo cardiovascular como ocurre usualmente.

ABSTRACT

La utilización de la cromatografía de afinidad con concanavalina A o de cromatografía de inmunoafinidad con anticuerpos anti apoB permite obtener dos grupos de lipoproteínas: las que contienen apoA y las que contienen apoB. El subfraccionamiento por cromatografía de inmunoafinidad secuencial de las partículas lipoproteicas que contienen apoA permite obtener a su vez tres mayores partículas lipoproteicas: LP-A-I, LP-A-I:A-II y LP-A-II. El subfraccionamiento a través de inmunoprecipitación secuencial o cromatografía de inmunoafinidad secuencial de las partículas lipoproteicas que contienen apoB permite obtener cinco mayores grupos de partículas: LP-B, LP-B:C, LP-B:E, LP-B:C:E y LP-A-II:B. La diferencia entre normo e hiperlipoproteinémicos sería el resultado de cambios cuantitativos (y no cualitativos) de las partículas lipoproteicas. En hipercolesterolémicos se destaca un aumento de LP-B en tanto que en hipertrigliceridémicos aumentan la LP-B-C y LP-B:C:E. Las drogas hipolipemiantes, independientemente de su mecanismo de acción, afectan en diferentes sentidos las concentraciones de las partículas lipoproteicas que contienen apoA y apoB. Bajas concentraciones de LP-A-I y elevadas de LP-B:C y LP-B:C:E se asocian con riesgo aterogénico

ABSTRACT

Purpose - To compare the effects of lovastatin and gemfibrozil in patients with primary hyperlipidemias. Patients and Methods - Forty patients with cholesterolemia over 200 mgldl and triglyceridemia not higher than 350 mp/dl, excluded secondary causes, were selected. Twenty patients received lovastatin and 20 gemfibrozil. In order to establish the lipid profile, blood samples were taken after 2 months without medication, after 4 weeks of diet and placebo and after 6 and 12 weeks active treatment. Biochemic profile was determined before and after the treatment with active drug. Results - Thirty nine patients completed the study. Total and LDL-cholesterol were significantly reduced (p < 0.05) by both drugs but lovastatin had greater effect. Only gemfibrozil reduced triglycerides significantly. Neither drug had significant effects on HDL-cholesterol. The tolerance was satisfactory; only one patient (using gemfibrozil) needed to stop the treatment due to gastrointestinal side effects. The biochemic profïle did not present any significant alteration. Conclusion - Both drugs produced useful effects on the lipid profile. Lovastatin produced greater reductions of total and LDL-cholesterol, while gemfibrozil was more active reducing triglycerides. Neither drug changed significantly the HDL-cholesterol

ABSTRACT

Gemfibrozil, a lipid lowering agent, was administered to two patients with familial hyperlipidaemia and one patient with insulin dependent diabetes mellitus. It was partially effective in familial hyperlipidaemia. It dramatically reduced triglyceride and cholesterol levels in the patient with Type V hyperlipidaemia and insulin dependent diabetes mellitus. Patients with familial and Type V hyperlipidaemias should be given a trial of gemfibrozil therapy.

ABSTRACT

The efficacy of Gemfibrozil on S. lipid levels was studied in 36 middle aged subjects with type IIA, IIB, IV hyperlipidemia. Gemfibrozil was well tolerated in the dose of 1200 mg/day and no dropouts were attributable to its use. An overall reduction in total cholesterol (39.91%), total triglycerides (71.10%), VLDL triglycerides (62.97%). LDL cholesterol (45.57%) and apolipoprotein B levels (26.83%) were observed at 24 weeks. At the same time HDL cholesterol, and apolipoprotein A levels showed increases by 26.23% and 53.67% respectively. It is concluded that Gemfibrozil is an effective lipid lowering agent. Further long term studies are necessary to determine its optimal dosage and its long term safety in Indian subjects.
