Purpose: The chemical interactions that cause drug incompatibility in solutions, with emphasis on the acid-base and ionized-nonionized forms of organic, weak, electrolyte drugs, are examined.

Federal offices (e.g., Food and Drug Administration, Patent and Trademark Office) as well as state and local governments hire organic chemists in the fields of specialization noted above.

Also, eating meat from animals that are fed antibiotics might make these drugs less helpful at treating bacterial infections in people. If your food is labeled "USDA Organic," does that mean it's ...

When the dilution or mixing of the salt or ionized forms of organic drugs results in precipitation, the most likely cause is formation of the nonionized drug forms. Yet, for example, when ...
