Resumen
Este resumen es generado por máquina.Los comprimidos genéricos de fenobarbital son bioequivalentes a la formulación original, ofreciendo una opción asequible de tratamiento de la epilepsia en China. La comida puede disminuir la absorción de fenobarbital, lo que afecta a la eficacia del medicamento.
Área De La Ciencia
- Estudios de farmacocinética y bioequivalencia
- Neurología y Ciencias Farmacéuticas
Sus Antecedentes
- La epilepsia es un trastorno neurológico grave con opciones de tratamiento limitadas en China.
- El fenobarbital es un medicamento crítico e insustituible para varios tipos de convulsiones, sin embargo, su formulación original no está disponible en el país.
- La necesidad de un fenobarbital genérico accesible y rentable es significativa para los pacientes chinos.
Objetivo Del Estudio
- Establecer la bioequivalencia entre un comprimido genérico de fenobarbital (Shandong Xinhua Pharmaceutical) y el producto de referencia (Phenobal).
- Evaluar el impacto de los alimentos en el perfil farmacocinético del fenobarbital.
- Apoyar el lanzamiento al mercado del fenobarbital genérico en China.
Principales Métodos
- Un estudio de diseño abierto, aleatorizado, de un solo centro, de una sola dosis, de dos períodos, de dos secuencias cruzadas y paralelas.
- Comparación de los comprimidos de fenobarbital de Shandong Xinhua Pharmaceutical (prueba) con el Phenobal de Fujinaga Pharmaceutical (referencia).
- Investigación del efecto de los alimentos en los parámetros farmacocinéticos, incluida la Cmax y la exposición global.
Principales Resultados
- Los comprimidos genéricos de fenobarbital demostraron bioequivalencia con la formulación de referencia.
- Se observó que la ingesta de alimentos potencialmente reduce la concentración máxima (Cmax) y la exposición general del fenobarbital.
- El estudio cumplió su objetivo principal de demostrar la equivalencia terapéutica del medicamento genérico.
Conclusiones
- La formulación genérica de fenobarbital es bioequivalente al producto de referencia, validando su idoneidad para el tratamiento de la epilepsia.
- Los hallazgos sugieren que la administración de fenobarbital sin alimentos puede optimizar la exposición y la eficacia del fármaco.
- Esta investigación proporciona datos cruciales para la aprobación y el uso racional del fenobarbital genérico en China.

The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.

Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...
Phase I biotransformation reactions are integral to drug metabolism, predominantly involving oxidative, reductive, and hydrolytic transformations. Chief among these are oxidative reactions, which enhance the hydrophilicity of xenobiotics and introduce polar functional groups to facilitate their elimination from the body.
Oxidation reactions are fundamental in aromatic carbon-containing systems. An example is the hydroxylation of phenobarbital, a process that transforms it into...
Biological factors significantly impact drug metabolism, influencing drug clearance, efficacy, and potential toxicity.
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
When a drug follows nonlinear pharmacokinetics, its bioavailability, the amount of the drug that reaches the systemic circulation, can change with different doses. This is due to the presence of a saturable pathway. The pathway becomes saturated as the drug concentration increases, decreasing the absorption rate. Consequently, the drug's bioavailability may be lower than expected at higher doses.
To quantify the extent of bioavailability, pharmacologists often use a parameter called .
Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...
