Padrões Farmacêuticas
Os padrões farmacêuticos são um conjunto abrangente de materiais de referência essenciais para garantir a segurança, eficácia e qualidade dos produtos farmacêuticos. Esta categoria inclui padrões para ingredientes farmacêuticos ativos (APIs), que são os componentes principais responsáveis pelos efeitos terapêuticos. Além disso, abrange compostos e metabólitos relevantes tanto para a indústria farmacêutica quanto veterinária, fornecendo referências para a medição e análise precisa dessas substâncias. Padrões de controle de nitrosaminas são cruciais para detectar e mitigar nitrosaminas potencialmente prejudiciais em formulações de medicamentos. Padrões de toxicologia ajudam a avaliar a segurança e os potenciais efeitos adversos de compostos farmacêuticos. Além disso, padrões de ativadores e inibidores de enzimas são vitais para pesquisa e desenvolvimento, permitindo estudos precisos de vias bioquímicas e mecanismos de ação de medicamentos. Esses padrões farmacêuticos são ferramentas indispensáveis para conformidade regulatória, controle de qualidade e pesquisa, garantindo que os produtos farmacêuticos atendam a rigorosos critérios de segurança e eficácia.
