A sample can be collected from an enclosed container, such as an aseptic bioreactor or chemical environment, using the disclosed sampling modules and manifold, providing consistent or substantially consistent sampling procedures for obtaining samples of a desired quality, while reducing the risk of contamination. The samples can be directed to appropriate analytical devices for analysis.

A spray-drying apparatus includes a drying chamber that has a first end, a second end, and at least one side wall extending between the first and second ends to define an interior of the drying chamber having a center axis. A nozzle can be positioned at the first end of the drying chamber and be configured to atomize liquid and spray the atomized liquid into the interior of the drying chamber at a maximum spray pattern angle relative to the center axis. A heating device can be provided to heat the liquid prior to introduction into the drying chamber.


Conventional spray-drying methods are improved by incorporation of a pressure nozzle and a diffuser plate to improve the flow of drying gas and a drying chamber extension to increase drying time, such improvements leading to the formation of homogeneous solid dispersions of drugs in concentration-enhancing polymers.

Spray dried solid dispersions comprising a sparingly soluble drug and hydroxypropylmethylcellulose acetate succinate (HPMCAS) provide increased aqueous solubility and/or bioavailability in a use environment.

A drug in a solubility-improved form is combined with a concentration-enhancing polymer in a sufficient amount so that the combination provides substantially enhanced drug concentration in a use environment relative to a control comprising the same amount of the same solubility-improved form of drug without the concentration-enhancing polymer.
