The Short Answer
As well as the gastrointestinal pH affecting drug absorption some drugs are purposely given with or immediately after a meal to slow down absorption or to provide short term protection against the acidic nature of the stomach contents (the presence of food raises the stomach pH towards neutral). Drugs mixed with food pass into the small intestine more slowly than drug mixed in stomach secretions alone. For some drugs it is necessary to control the rate of absorption to stop large quantities of the drug entering the blood stream quickly and giving what are known as peak plasma level side effects (typically nausea and vomiting from high plasma levels being reached quickly). Slower absorption from mixing with food can still let the same amount of drug into the blood but the levels do not get so high as those that cause the nausea and vomiting experienced by some patients. This is a very simplified picture (source: pharmacist involved in drug development for more than 30 years).
