How to determine if a drug is acidic or basic
WebSolutions are classified as acidic or basic based on their hydrogen ion concentration relative to pure water. Acidic solutions have a higher H ^+ + concentration than water (greater than 1 × 10 ^ {-7} −7 M), while basic … WebWeakly acidic drugs are predominantly of the unionized form at lower pH of the gastric fluid, and absorbed from the stomach as well as intestine. Some very weak acidic drugs, such as phenytoin and many barbiturates, whose pKa values are greater than 7, are essentially unionized at all pH values.
