Standard farmaceutici
Gli standard farmaceutici sono un insieme completo di materiali di riferimento essenziali per garantire la sicurezza, l'efficacia e la qualità dei prodotti farmaceutici. Questa categoria include standard per ingredienti farmaceutici attivi (API), che sono i componenti principali responsabili degli effetti terapeutici. Inoltre, copre composti e metaboliti rilevanti sia per l'industria farmaceutica che veterinaria, fornendo punti di riferimento per la misurazione e l'analisi precisa di queste sostanze. Gli standard di controllo delle nitrosammine sono cruciali per rilevare e mitigare le nitrosammine potenzialmente dannose nelle formulazioni di farmaci. Gli standard di tossicologia aiutano a valutare la sicurezza e i potenziali effetti avversi dei composti farmaceutici. Inoltre, gli standard per attivatori e inibitori enzimatici sono vitali per la ricerca e lo sviluppo, consentendo studi precisi delle vie biochimiche e dei meccanismi d'azione dei farmaci. Questi standard farmaceutici sono strumenti indispensabili per la conformità normativa, il controllo di qualità e la ricerca, garantendo che i prodotti farmaceutici soddisfino rigorosi criteri di sicurezza ed efficacia.
