The strengths currently involved in this change are the 2 gr (120
mg) , 3 gr (180
mg), 4 gr (240
mg) and 5 gr (300 gr). If we maintain our current schedule, these strengths should be available in October. During this time, we will continue to manufacture the .25 gr, .50 gr, 1 gr, and 1.5 gr tablets. However, we may encounter short-term backorders on these strengths as a result of increase in demand."
I am not sure what "enhance" means - but I am trying to learn more.
