Dissolution Testing USP 4

The flow-through dissolution method offers complete flexibility on media volumes and allows repeatable positioning of virtually all dosage forms such as powders, APIs, lipophilic forms, suppositories, suspensions, liposomes, microspheres, semi-solids, implants, and medical devices including drug eluting stents. Described in the United States Pharmacopeia (USP) as Apparatus 4, in the European Pharmacopeia (EP) as Flow-through cell, in the Japanese Pharmacopeia (JP) as Apparatus 3, in the Chinese Pharmacopeia (ChP) as Method 6, and other Pharmacopeia, dissolution and drug release testing using a flow-through cell is proven to characterize the active drug release in terms of bioequivalence and in-vitro / in-vivo correlation (IVIVC) in clinical studies and daily QC routines alike.

Dissolution Testers

Sometimes referred to as the "Swiss Army Knife", flow-through cells allow dissolution testing of virtually all dosage forms. SOTAX was the first manufacturer to develop a standardized flow-through dissolution tester and has ever since helped pharmaceutical companies all over the world in designing robust flow-through methods - and new flow-through cells for novel dosage forms.

Applications

Applications

As dosage forms vary so do the requirements for dissolution testing.  Depending on the route of administration or analytical sensitivity the length of the test or volume of dissolution media can vary drastically.  The flow-through dissolution method flexibly accommodates the demanding nature of even the trickiest formulations because of the ability to adjust hydrodynamics and media volumes dynamically.

Software

Software

The WinSOTAX®plus software is 21 CFR Part 11 compliant, controlling all aspects of data capture and reporting with CE 7smart flow-through dissolution testers. Drivers for different UV-Vis spectrophotometers allow to analyze dissolution samples online and in real-time. If needed, you can also network conventional USP 1/2/5/6 dissolution testers performing dissolution tests with paddle & basket methods.
