The absorption of acetylsalicylic acid from the stomach in relation to intragastric pH.

摘要: A comparative study on the effect of a buffered (pH 6.5) and an unbuffered 2.9) solution acetylsalicylic acid (ASA) gastric pH, emptying, absorption ASA was performed in 10 healthy volunteers. Gastric pH recorded using radiotelemetry. emptying studied with aspiration technique phenol red as nonabsorbable marker. Administration to fasting subjects resulted about 2 from stomach found occur. The increased above 5 be significantly less than after solution. emptied more rapidly one.
