When assessing inhaled drug absorption, standard pharmacokinetic analyses cannot differentiate drug that reaches the systemic circulation from the lungs from that of the gut. Pulmonary absorption kinetics can be assessed for drugs with negligible gastrointestinal absorption or for drugs that are eliminated via first-pass metabolism. For other drugs, pulmonary absorption kinetics can be studied by blocking gastrointestinal absorption with charcoal, or by studying absorption during the first 30… CONTINUE READING
