Summary. This paper is not about rural innovation. It is a pharmaceutical sciences study examining pH, buffer capacity, and motility in the human gastrointestinal tract to improve drug dissolution and absorption predictions. The authors measured these properties in healthy subjects after ibuprofen administration under fasted and fed conditions, finding extremely low buffer capacity throughout the upper GI tract with important implications for oral drug delivery formulation.
