Ph partition theory of drug absorption is based on the ... predicted from ph partition ... A guide to the lipophilic nature of a drug is its partition Limitations of pH Partition Theory. pH partition theory often doesn't hold true for most weak ... Drug absorption is also affected by its lipid solubility. pH partition is the tendency for acids to accumulate in basic fluid compartments, and bases to accumulate in acidic compartments.
