If there has been a decrease in demand for the drug, we would expect to see a decrease in the equilibrium quantity. This is because at a lower price, there will be less demand for the drug and therefore less of it will be sold, resulting in a lower equilibrium quantity. A shortage or surplus may be indicative of other factors affecting the market, but are not necessarily related to changes in demand alone. An increase in the equilibrium quantity would not support the idea of lower drug prices being attributed to a decrease in demand.
