The pharmacokinetic and pharmacodynamic properties of orally administered BBP-671 evaluated in cannulated rats showed that CoA concentrations were elevated in blood, liver and brain. This work describes the pharmacokinetic/pharmacodynamic properties of BBP-671, a pantothenate kinase activator.
Together, the tools estimate how a drug may impact diverse outcomes of interest to drug developers: general cellular health, pharmacokinetics, and heart and liver function. Drug developers also assess pharmacokinetic effects, or how an organism absorbs, distributes, metabolizes, and clears a drug.
What are the primary considerations in optimising the pharmacokinetics (PK) and biodistribution of MC4R-specific nanobodies in preclinical obesity models, and how does Confo Therapeutics plan to address challenges related to blood-brain barrier penetration?
A small clinical trial with a pharmacokinetic sub-study, led by a world-renowned pharmacologist at the University of Houston, has demonstrated the promising effectiveness of the drug Riluzole for improving functionality in people with acute spinal cord injuries (SCI) if the drug is taken within 12 hours post-injury.
