Aspirin and other nonsteroidal anti-inflammatory drugs (NSAID) inhibit inflammation by inhibiting an enzyme in the prostaglandin pathway. However, inhibiting this enzyme also inhibits other pathways that protect the stomach from damage by stomach acid and that form blood clots. What can you conclude from this? Aspirin and other nonsteroidal anti-inflammatory drugs (NSAID) inhibit inflammation by inhibiting an enzyme in the prostaglandin pathway. However, inhibiting this enzyme also inhibits other pathways that protect the stomach from damage by stomach acid and that form blood clots. What can you conclude from this? The enzyme is found in many different types of cells. Prostaglandins cause blood clotting. Aspirin should not be given to people who people who need to synthesize enzymes. The enzyme inhibition is nonreversible.

The result that can be concluded is that this enzyme is found in different types of cells. This is the reason that the medicines like aspirin and other non-steroidal anti inflammatory drugs inhibit the prostaglandin pathway and other pathways too.

These medication acts on the enzymes and it will act in the cells where this enzyme will be present. Hence, the enzyme is acting in different types of cells.
