WebExamples of counter-ion influence on peptide formulation are set out in Table 2. 3.2.2. Peptide Hydrophobic Ion Pairing. The use of most peptide drugs, based on hydrophilicity, and hence the poor membrane permeability, as well as low enzymatic stability, is restricted to intravenous, subcutaneous, and intramuscular administration. However, as ...
