Diarrhea is a very common problem in children. Diarrhea is frequent, loose, or watery bowel movements (BMs) that differ from a childâs normal pattern. Sometimes diarrhea contains blood or mucus. Identifying mild diarrhea may be difficult because in healthy children, the number and consistency of BMs vary with age and diet.
Aspirin and nonaspirin nonsteroidal antiinflammatory drugs (NSAIDs) inhibit platelet cyclooxygenase, thereby blocking the formation of thromboxane A2. These drugs produce a systemic bleeding tendency by impairing thromboxane-dependent platelet aggregation and consequently prolonging the bleeding time.
Protease inhibitors are drugs that resemble pieces of the protein chain that protease normally cuts. By gumming up the protease scissors, HIV protease inhibitors prevent protease from cutting long chains of proteins and enzymes into the shorter pieces that HIV needs to make new copies of itself (Figure 1) .rotease inhibitors are drugs that slow down the spread of HIV -- the virus that causes AIDS -- inside the body.
