 Variability in PK from IM injection [PK / PD]

Hi everyone,

I once heard that IM injection tends to yield higher variability in PK, is that true? Relative to IV.

Thanks

 Variability in PK from IM injection

Hi John,

» I once heard that IM injection tends to yield higher variability in PK, is that true? Relative to IV.

I think that's true by some margin, usually.
One joker is that IM is not IM. Quite a few IM injections end up being SC in part or in whole.

I could be wrong, but...

Best regards,

R's base package has 274 reserved words and operators, along with 1761 functions. I can use 18 of them (about 14 of them properly). I believe this makes me the Donald Trump of programming.

 Variability EV > IV (always)

Hi John,

» […] IM injection tends to yield higher variability in PK, is that true? Relative to IV.

By “definition”?
As soon as you add an entry compartment to the system, its inherent variability will increase the overall variability, since the variability you already have (elimination and eventual distribution) will remain constant (driven only by the properties of the drug).

Sorry for the long sentence.
