Question on Davis' s Drug Guide for Nurses

[khrfx4]

I've searched the internet and Davis's Guide and have come up empty.

Under TIME/ACTION PROFILE (Onset, Peak, Duration) for Cefaclor they use a Route abbreviated PO-CD and on Nitroglycerin PO-ER.

I assume the PO means by mouth, but can't work out the meanings for CD or ER.

On the chance there are more of these odd abbreviations, does anyone know where a table of them are located in Davis's Guide?

Thanks

Not positive what the CD words mean, but it looks similar to ER (Extended Release).

"While the abbreviations used to denote sustained activity refer to different technologies with different characteristics, they have no specific meanings

and appear to be randomly chosen, Cohen said. This leads to confusion among

physicians, pharmacists, and patients. Consider the following alphabet soup

of suffixes: XL, SR, CD, LA, XT, to name just a few."

Dr Google tells me that the CD in a medication name means controlled delivery.

Thanks CalicoKitty. With your clue for ER I was able to make a better search in Google and I also came up with the same thing Vanilla Bean came up with -- "Controlled Delivery", which certainly seems to just be another way to say ER.
