Estándares farmacéuticos
Los estándares farmacéuticos son un conjunto integral de materiales de referencia esenciales para garantizar la seguridad, eficacia y calidad de los productos farmacéuticos. Esta categoría incluye estándares para ingredientes farmacéuticos activos (APIs), que son los componentes centrales responsables de los efectos terapéuticos. Además, abarca compuestos y metabolitos relevantes tanto para las industrias farmacéutica como veterinaria, proporcionando puntos de referencia para la medición y análisis precisos de estas sustancias. Los estándares de control de nitrosaminas son cruciales para detectar y mitigar las nitrosaminas potencialmente dañinas en las formulaciones de medicamentos. Los estándares de toxicología ayudan a evaluar la seguridad y los posibles efectos adversos de los compuestos farmacéuticos. Además, los estándares de activadores e inhibidores enzimáticos son vitales para la investigación y el desarrollo, permitiendo estudios precisos de las vías bioquímicas y los mecanismos de acción de los medicamentos. Estos estándares farmacéuticos son herramientas indispensables para el cumplimiento normativo, el control de calidad y la investigación, asegurando que los productos farmacéuticos cumplan con estrictos criterios de seguridad y eficacia.
