Empirical tests have shown certain factories manufactured drugs with insufficient concentration of the active ingredient. Basically, they are making more profit by selling a placebo. This is often the case with low cost generics. When the low cost generics are ineffective, doctors prescribe more expensive alternatives produced by the same manufacturer --- again they generate more profit.
