Molecular Design

MARCH 31, 2019

Drug design is a multi-objective endeavor. Other objectives such as controllability of exposure are much less easily defined and this means that drug design is indirect. Some objectives such as maximization of affinity against target(s) and minimization of affinity against anti-targets are easily defined.

Awareness of drug interactions involving opioids is critical for patient treatment as they are common therapeutics used in numerous care settings including both chronic and disease related pain. Not only do opioids have narrow therapeutic indexes and are extensively used, but they have the potential to cause severe toxicity.
