Cool technology for pharmacy – Formulary Toolkit

Omnicell has been busy developing the IV automation and technology that they acquired from Aeysnt. Honestly, a couple of years ago I was ready to write off Aesynt’s presence in the IV room because of their tiny market share. This is when their current IV room products were still part of Health Robotics. With that said, the IV group has effectively reinvented themselves over the past couple of years and are doing some really neat stuff.

Two developments that I’m particularly excited about are REINVENT and Formulary Toolkit (FTK). I’ve written about REINVENT several times already, most recently just 6 days ago. I’ve mentioned FTK a couple of times in passing but have never really understood what it was, until now.


Aesynt website: “Said John Barickman, senior executive IV pharmacist consultant at Aesynt.  “With the Formulary Toolkit, we can now offer pharmacies data and services to better leverage automation technology and enable best practices in pharmacy like beyond use dating.”… Formulary Toolkit provides cost-effective access to cGMP quality gravity and drug stability data, in combination with established robust sterility protocols and testing services, that can be utilized to extend beyond use dates for compounded sterile preparations.”

Basically, Omnicell (previously Aesynt) has taken it upon themselves to do CSP stability testing for a select group of drugs. They do this to offer extended beyond use dating (BUD) for sterile compounds. Why would they do that? Sit back and I’ll tell you.

The BUD for a CSP identifies the time by which the preparation – once mixed – must be used before it is at risk for chemical degradation, contamination, and permeability of the packaging. In the absence of direct sterility and stability testing evidence that supports longer BUDs, USP <797> currently states that low-risk CSPs are good at controlled room temperature for 48 hours, at cold temperature (refrigerated) for 14 days, and frozen for 45 days. For medium-risk compounds, BUDs are 30 hours, 9 days, and 45 days, respectively.

Given appropriate stability and sterility testing, BUDs can be extended, giving a hospital the ability to plan further ahead, reduce waste, and better allocate resources. FTK takes care of the stability testing, giving pharmacies one important piece of the puzzle they need to create large batches with extended BUDs. Once extended BUDs have been established by laboratory testing, facilities have only to test batches for sterility.

So let’s say your pharmacy services several facilities in your healthcare system and uses a ton of vancomycin 1250 mg in 250 mL D5W [Baxter bags]. According to USP <797> you can get 14 days in the refrigerator or 48 hours at room temperature. However, what if stability studies demonstrated that the same CSPs were stable for 90 days at room temperature? You would be able to make significantly larger batches. Prior to using the batch, it would need to be quarantined while sterility testing was performed, which usually takes a couple of weeks. But, when the sample returned negative results, the batch could be used for the remainder of the 90 days, effectively extending the BUD by more than four-fold. This is such an advantage for pharmacies that must prepare frequent, large batches of specific drugs.

I don’t know what drugs have been tested for inclusion in FTK, but I’ve been told that data for several drugs in currently available and more are being added each quarter. Very cool.

  1. Do you know if they will give you specific data for your particular pharmacy? Would you send in your pharmacies samples to their laboratory for testing?

  2. Hi Matthew – please see my email response. Ultimately I do not believe this is how the service works.
