Displaying 2 results of Fidaxomicin Stable Isotopes Fidaxomicin is a potent antibacterial drug used in the treatment of Clostridium difficile infection. Stable isotopes of Fidaxomicin are synthetic molecules with atoms of the same element but different neutron numbers. These isotopes are chemically identical to the natural compound and are used in research, drug development, and clinical studies for pharmacokinetic and pharmacodynamic analysis. The use of stable isotopes in drug development offers advantages such as increased sensitivity, specificity, and accuracy in measuring drug levels and metabolism.
