E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the minimum dose and pharmacokinetics (Tmax, Cmax, metabolite ratios / active ingredient in blood and urine) for each of the active ingredients of Frenadol COMPLEX ® (acetaminophen, dextromethorphan, chlorpheniramine and caffeine) in volunteer subjects. and the optimum time for taking samples (blood and urine) for the efficient determination of the metabolites Administer the drug that is the basis of Hepatotest (Frenadol Complex) to patients who are operated on for liver surgery preoperatively, determining the presence of metabolites in blood and urine. After the taking of a tissue sample is determined activity per gram of tissue of the enzymes that are involved in the metabolism of the aforementioned drugs |
Determinar la dosis mínima y la farmacocinética (Tmáx, Cmáx, ratios metabolito/principio activo en sangre y orina) para cada uno de los principios activos del FRENADOL®COMPLEX (paracetamol, dextrometorfano, clorfenamina y cafeína) en sujetos voluntarios. y el tiempo óptimo para la toma de muestras (sangre y orina), para una eficaz determinación de los metabolitos Administrar el fármaco que constituye la base del Hepatotest (Frenadol Complex) a pacientes que sean intervenidos por una cirugía hepática antes de la intervención, determinando la presencia de metabolitos en sangre y orina. Tras la toma de una muestra de tejido se determinarán la actividad por gramo de tejido de los enzimas que están implicados en el metabolismo de los anteriormente citados fármacos |
|
E.2.2 | Secondary objectives of the trial |
Establish a procedure for sampling, processing and analysis that is robust, reproducible and consistent with current clinical practice for drug administration and measurement of metabolites in blood and urine. Development of an algorithm for correlating the results of metabolite concentrations in serum / urine with the enzymatic activities measured in liver tissue |
Establecer un procedimiento para la toma de muestras, procesamiento y análisis que sea robusto, reproducible y compatible con la práctica clínica habitual, para la administración del fármaco y la medida de los metabolitos en sangre y orina. Desarrollar de un algoritmo que permita correlacionar los resultados de concentraciones de metabolitos en suero/orina con las actividades enzimáticas medidas en tejido hepático |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Group volunteers: volunteer subjects without severe liver pathology associated. Group patients: Patients who are to undergo abdominal surgery (liver resection preferably in the context of the underlying pathology, eg liver metastases, hepatic adenoma, cholangiocarcinoma, etc ...). |
Grupo voluntarios: Sujetos voluntarios sin patología hepática grave asociada. Grupo pacientes: Pacientes que vayan a ser sometidos a una intervención quirúrgica abdominal (preferentemente una resección hepática en el contexto de su patología de base, por ejemplo metástasis hepática, adenoma hepático, colangiocarcinoma, etc...). |
|
E.4 | Principal exclusion criteria |
Group volunteers: under 18 years, pregnant and lactating women, allergy to any of the active substances or excipients, allergy to acetylsalicylic acid, liver pathology associated (cirrhosis, hepatitis, liver tumor pathology), moderate consumption of alcohol, renal failure (creatinine of 1.2mg/dl or less glomerular filtration of 90 ml / min). Group patients: below 18, allergy to any of the active ingredients or allergy to acetylsalicylic acid, renal failure (creatinine of 1.2mg/dl or less glomerular filtration of 90 ml / min), the appearance of other pathological conditions over study that contraindicate surgery. Pregnant women and lactating. |
Grupo voluntarios: Menores de 18 años, embarazadas y mujeres en periodo de lactancia, alergia a alguno de los principios activos o excipientes, alergia a ácido acetil salicílico, patología hepática asociada (cirrosis, hepatitis, patología tumoral hepática), consumo de alcohol moderado, insuficiencia renal (creatinina mayor de 1.2mg/dl o filtrado glomerular menor de 90 ml/min). Grupo pacientes: Menores de 18 años, alergia a alguno de los principios activos o, alergia a ácido acetil salicílico, insuficiencia renal (creatinina mayor de 1.2mg/dl o filtrado glomerular menor de 90 ml/min), aparición de otras circunstancias patológicas durante el estudio que contraindiquen la cirugía. Mujeres embarazadas y en periodo de lactancia. |
