Ibuprofen amide is a nonsteroidal anti-inflammatory drug that belongs to the class of amides. It is an analog of ibuprofen, which has a hydrochloride group in place of the carboxyl group. Ibuprofen amide inhibits the production of pro-inflammatory chemicals by blocking cyclooxygenase enzymes, which are responsible for synthesis of prostaglandins and thromboxanes. The kinetic profile of this compound was obtained using fluorescence spectroscopy. This analytical method also showed that ibuprofen amide hydrolyzes in acidic conditions, suggesting that it may be active against bacteria that are found in an acidic environment.

Hydrochlorothiazide is a sulfonamide that inhibits the activity of the enzyme, angiotensin-converting enzyme (ACE), which is responsible for converting angiotensin I to the potent vasoconstrictor, angiotensin II. It also has antihypertensive effects by blocking the production of aldosterone, which causes sodium retention and leads to high blood pressure. It is a byproduct in reactions with substances such as valsartan. Hydrochlorothiazide may react chemically with other medicines such as ampicillin and cefaclor.

2-(4-Formylphenyl)propionic acid is a racemic mixture of 2-formylphenylacetic acid and 4-formylphenylacetic acid. This compound is used in the treatment of bacterial infections and inflammation.
