HOW DO ANALGESIC/ANTIHISTAMINE/ANTITUSSIVE COMBOS WORK?

Analgesic/antihistamine/antitussive combos are over-the-counter medicines used for treating cold and flu symptoms. 

Analgesics reduce pain and fever associated with cold and flu symptoms. They block pain signal generation and generation of prostaglandins from the central nervous system released during fever. Thus, blocking the generation of prostaglandins helps in lowering the body temperature.

Antihistamines block the release of a chemical called histamine. Histamine is responsible for the itching and swelling of the tissues in the nose. Thus, antihistamines help relieve runny noses and sneezing during a cold.

Although the exact mechanism of action of antitussives (cough suppressants) is not known; they suppress coughing by inhibiting a coordinating region for coughing located in the brain stem.
