Pharm should need to rename any drugs that are reformulated rather than being permitted to extend a patent based on reformulation. Perhaps there needs to be an attachment to applicable research but a drug should not be sold and advertised as the same if they changed it.
A look into the patent process should be undertaken to determine if it is becoming a risk to the public by both allowing medications to be protected after they have been changed and therefore not investigated properly and also if it is preventing progress from being made to cure and heal disease.
In addition, medication which are sold to create lifetime dependency should be investigated to determine if a cure is being prevented for profit.
