Encapsulation Efficiency of Temazepam NLCs

The encapsulation efficiency (EE%) of temazepam within NLCs was calculated indirectly by measuring unincorporated temazepam spectrophotometrically using (Shimadzu, model UV-1601 PC, Kyoto, Japan), at λ = 232 nm, after ultrafiltration of temazepam NLCs suspension using (Amicon^® Ultra-4 30k Merck Millipore, Fisher Scientific, Pittsburgh, PA, USA) at (4000× g) for 10 min.
Calculations were performed according to:

EE % = \frac{[(WT - WF)]}{WT} \times 100 %

where WT = weight of total drug added, and WF = weight of free un-entrapped drug quantified in the ultrafiltrate, respectively.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
