Provided that a drug is sure non-especially into a protein, it are unable to Possess a therapeutic action, nor can it's removed (metabolized hepatically through the liver or excreted via the kidneys).

POTENCY due to check here the fact one particular could manipulate the drug dose to supply the attractive response in case of a drug with reduced potency but a drug with very low efficacy could not be manipulated in exactly the same way.
