I am a pharmacist in a busy retail community pharmacy and we do good
numbers but very little compounding.  I received this order today:

docusate sodium 283mg/3.4ml mini-enemas #30

The patient brought in his previous docusate mini-enemas, which were
filled at an out-of-state compounding pharmacy.  The finished product
is 3.4ml liquid in a 10ml syringe, which is capped.  Prior to
administration, the cap is removed and a rectal applicator is screwed
onto the barrel.

This order looked pretty simple when I received it, but I quickly ran
into problems.  First, what is the best way to get 283mg DOS into the
3.4ml of solution?  I cannot find any DOS solution stronger than
50mg/ml.  Second, looking in my Cardinal wholesaler book, I can't
figure out what the screw-on rectal applicators might be called.

Any help is appreciated - I have a couple weeks to fill the order.  I
would refer the patient to a compounding pharmacy but he is determined
to get all of his scripts filled at our site.
