These are some of the most prescribed drugs in America, the trend is quite clear. Every drug except albuterol and levothyroxine has decreased dramatically in price. Levothyroxine's patent expired this year so there will be some time before prices go down. Albuterol is expensive because the inhaler had to change the propellant to remove CFCs and there is a new patent on the hydrofluoroalkanes (HFAs) that has yet to expire.
