DESCRIPCiÓN Description

Una composición farmacéutica que contiene ketamina yamitriptilina A pharmaceutical composition containing ketamine yamitriptyline

La presente invención tiene por objeto una composición farmacéutica de uso tópico conteniendo como principios activos ketamina en una proporción superior al 2,5% en peso y preferentemente un 3%, y amitriptilina en una proporción superior al 3% en peso, y preferentemente un 4%. The present invention aims at a pharmaceutical composition for topical use containing as active ingredients ketamine in a proportion greater than 2.5% by weight and preferably 3%, and amitriptyline in a proportion greater than 3% by weight, and preferably 4 %.

El dolor Neuropático (DN) está asociado a lesiones o disfunciones del sistema nervioso provocadas por múltiples enfermedades y es motivo de consulta muy frecuente en las Unidades Especializadas de Tratamiento de Dolor. Neuropathic pain (DN) is associated with lesions or dysfunctions of the nervous system caused by multiple diseases and is a reason for frequent consultation in the Specialized Units of Pain Treatment.

Desde el punto de vista anatómico, las lesiones nerviosas responsables de la aparición del dolor pueden clasificarse en dos tipos, DN periférico, cuando las lesiones nerviosas se localizan en nervios periféricos o en raíces nerviosas y DN central cuando las lesiones nerviosas son a nivel del Sistema Nervioso Central (SNC), siendo múltiples, las causas que pueden provocar estas lesiones, compresiones y atrapamientos, traumatismos, infecciones, alteraciones metabólicas, isquemias, polineuropatías, enfermedades oncológicas, etc. From the anatomical point of view, the nerve lesions responsible for the onset of pain can be classified into two types, peripheral DN, when the nerve lesions are located in peripheral nerves or in nerve roots and central DN when the nerve lesions are at the System level Central Nervous (CNS), being multiple, the causes that can cause these injuries, compressions and entrapments, trauma, infections, metabolic alterations, ischemia, polyneuropathies, cancer diseases, etc.

Los pacientes con DN presentan gran variedad de síntomas aislados o asociados, entre los que destacan sensaciones anormalmente desagradables (disestesias), el aumento de la sensibilidad dolorosa Patients with DN have a wide variety of isolated or associated symptoms, among which abnormally unpleasant sensations (dysesthesias), increased pain sensitivity

espontánea o provocada (hiperalgesia), la sensación de dolor a spontaneous or provoked (hyperalgesia), the sensation of pain

estímulos que normalmente no producen dolor (alodinia), (parestesias) definidas como una sensación desagradable expresadas como hormigueo o cosquilleo, (hiperestesias) o aumento de la sensibilidad stimuli that normally do not produce pain (allodynia), (paraesthesia) defined as an unpleasant sensation expressed as tingling or tingling, (hyperesthesia) or increased sensitivity

5 táctil y térmica, (hiperpatía) o sensibilidad extrema y en algunos pacientes incluso (hipoestesia) o disminución de la sensibilidad superficial y dolor referido, metamérico o incluso en áreas lejanas. 5 tactile and thermal, (hyperpathy) or extreme sensitivity and in some patients even (hypoaesthesia) or decreased surface sensitivity and referred pain, metameric or even in remote areas.

15 A pesar de que se dispone de una gran cantidad de fármacos de primera línea y con evidencia científica para su tratamiento, antiepilépticos, antidepresivos, opioides, bloqueos nerviosos, estimulación medular etc., son frecuentes los fracasos terapéuticos o los efectos secundarios intolerables a los tratamientos. De forma que, 15 Despite the availability of a large number of first-line drugs with scientific evidence for their treatment, antiepileptics, antidepressants, opioids, nerve blocks, spinal stimulation, etc., therapeutic failures or side effects intolerable to patients are frequent. treatments So,

20 la persistencia y rebeldía del DN provoca en los pacientes altas tasas de sufrimiento, genera gran impacto económico y su inadecuado control representa un desafío para el profesional sanitario que los atiende. 20 the persistence and rebelliousness of the DN causes high rates of suffering in patients, generates great economic impact and its inadequate control represents a challenge for the healthcare professional who attends them.

La utilización de la vía tópica en el tratamiento del dolor es una alternativa en auge y de interés durante los últimos años. La capacidad de actuar a nivel de los receptores periféricos, la baja absorción sistémica y su reducido coste y fácil aplicación, le confiere a los fármacos analgésicos administrados por esta vía, un perfil favorable de seguridad, eficacia y coste frente a las otras vías alternativas existentes. The use of the topical route in the treatment of pain is a booming and interesting alternative in recent years. The ability to act at the level of peripheral receptors, low systemic absorption and its low cost and easy application, gives analgesic drugs administered by this route, a favorable profile of safety, efficacy and cost compared to the other existing alternative routes .

Existen preparados ya comercializados para su uso tópico como agentes analgésicos en el tratamiento del dolor de etiología neuropática. Así, la crema de capsaicina utilizada por vía tópica para el tratamiento del DN de distinta etiología debe ser aplicada a bajas concentraciones (0.025 1%) por sus efectos irritantes intensos. Estudios realizados muestran que la aplicación repetida de una dosis baja ( 0,075% ) de crema, o una sola aplicación de una dosis alta (8 % ) mediante parche, aunque puede proporcionar un alivio del dolor en algunos pacientes con dolor neuropático, es frecuente que la irritación local de la piel provoque la retirada del tratamiento, y las estimaciones sobre los beneficios y daños no son consistentes debido a la cantidad limitada de datos disponibles que avalen su uso para diferentes condiciones de DN. Los parches de lidocaína al 5%, están indicados para el alivio del dolor asociado con una neuralgia post herpética en mayores de 18 años. Pero aunque parece eficaz para el tratamiento del DN un meta análisis efectuado evaluando ensayos controlados aleatorios o cuasi aleatorizados que compararon There are preparations already marketed for topical use as analgesic agents in the treatment of neuropathic etiology pain. Thus, capsaicin cream used topically for the treatment of DN of different etiology should be applied at low concentrations (0.025 1%) for its intense irritating effects. Studies show that repeated application of a low dose (0.075%) of cream, or a single application of a high dose (8%) by patch, although it can provide pain relief in some patients with neuropathic pain, it is common that local skin irritation causes withdrawal of treatment, and estimates of benefits and damages are not consistent due to the limited amount of data available that support its use for different DN conditions. 5% lidocaine patches are indicated for pain relief associated with post herpetic neuralgia in people over 18 years. But although a meta analysis carried out by evaluating randomized or quasi-randomized controlled trials that compared comparisons seems effective for the treatment of DN

La combinación de la amitriptilina y ketamina por vía tópica está 10 descrita como una alternativa atractiva por el efecto analgésico aditivo y multimodal de ambos fármacos en el tratamiento del DN. The combination of amitriptyline and ketamine topically is described as an attractive alternative because of the additive and multimodal analgesic effect of both drugs in the treatment of DN.

Estado de la técnica State of the art

US 2003/0060463 Al describe un método para la preparación de composiciones utilizadas para el tratamiento del dolor. Según este método se utiliza la aplicación de composiciones por vía tópica a las áreas de piel afectadas por el dolor, conteniendo dichas composiciones tres clases de agentes terapéuticamente efectivos preparados en bases adecuadas; los agentes son antagonistas de los receptores NMDA, agentes anticolinérgicos, y agentes de bloqueo del simpático. Estos pueden ser utilizados solos o combinados. US 2003/0060463 Al describes a method for the preparation of compositions used for the treatment of pain. According to this method, the application of compositions is used topically to the areas of skin affected by pain, said compositions containing three kinds of therapeutically effective agents prepared on suitable bases; the agents are antagonists of NMDA receptors, anticholinergic agents, and sympathetic blocking agents. These can be used alone or in combination.

Sin embargo, aún cuando no quedan específicamente definidas, las proporciones que logran obtenerse no superan el 1% en el mejor de los casos, lo que resulta insatisfactorio para un tratamiento eficaz. La amitriptilina 2 % Y la Ketamina 2% administrada de forma tópica para el tratamiento del dolor neuropático localizado, ha sido asociada con efectos analgésicos para amplios periodos de tiempo (6 12 meses). Bien tolerada por los pacientes y sin riesgos de absorción sistémica, su efecto farmacológico se justifica por bloqueo de los receptores periféricos del N Metil D aspartato junto con sus propiedades anestésicas locales y la interacción con sistemas adenosina, siendo una alternativa sencilla y de interés. Pero son necesarias altas concentraciones de esta combinación de fármacos para provocar una significativa analgesia porque concentraciones de una mezcla de amitriptilina al 2% y 1 % ketamina, cuando fueron comparadas con crema de Amitriptilina 2% y de Ketamina 1 % no revelaron diferencias However, even if they are not specifically defined, the proportions that can be obtained do not exceed 1% in the best case, which is unsatisfactory for an effective treatment. Amitriptyline 2% and Ketamine 2% administered topically for the treatment of localized neuropathic pain, has been associated with analgesic effects for extended periods of time (6 12 months). Well tolerated by patients and without risks of systemic absorption, its pharmacological effect is justified by blocking the peripheral receptors of N Methyl D aspartate together with its local anesthetic properties and interaction with adenosine systems, being a simple and interesting alternative. But high concentrations of this combination of drugs are necessary to cause significant analgesia because concentrations of a mixture of 2% amitriptyline and 1% ketamine, when compared with 2% Amitriptyline cream and 1% Ketamine revealed no differences
