ABSTRACT

La Ivermectina, con más de 30 años de uso en humanos, es una droga que aún sigue siendo estudiada en otras indicaciones. Su seguridad es alta; se han dado casi 2.000 millones de dosis en humanos con efectos colaterales mínimos. Se excreta por las heces, no es nefrotóxica ni hepatotóxica. Es el tratamiento de elección en pacientes con SIDA, recibiendo terapia HAART para estrongiloidiasis sistémica y sarna noruega. Es empleada en niños mayores de dos años de edad o con más de 15 kilos de peso. La dosis es de 200 microgramos/kg en forma oral, al 0,6 por ciento en gotas (1 gota/kg de peso) y de 400 microgramos/kg en forma tópica al 0,1 por ciento (0,4 cc/kg de peso). Logró erradicar la oncocercosis que produce la “ceguera del río” y fue considerada como el triunfo de la humanidad sobre la adversidad por la OMS en 2009.


Ivermectin has been used during more than 30 years and yet it is an old drug in search for additional indications. Ivermectin has high safety profile, and more than 2 billion doses have been administered with mild side effects. Ivermectin is metabolized in the liver, and the drug or its metabolites are excreted almost exclusively in the feces over an estimated 12 days, with less than 1percent of the oral dose excreted in the urine. The plasma half-life of ivermectin in humans is approximately 18 hours following oral administration. Ivermectin is primarily metabolized by CYP3A4, and does not provoke hepato /nephrotoxicicty. This molecule is the gold standard treatment for strongyloidiasis and crusted scabies in patients with AIDS during treatment with HAART therapy. Ivermectin is used in children older than 2 years or more than 15 kg weight. Oral ivermectin 0.6 percent dose is 200 micrograms/kg (1 drop per kg) and topical ivermectin 0.1 percent dose is 400 micrograms/kg (0.4 cc per kg). Ivermectin was able to eliminate human river blindness (onchocerciasis) and “represent one of the most triumphant public health campaigns ever waged in the developing world” by WHO in 2009.
