The present invention relates to the dibenzoazulene compounds represented by formula I as well as to their pharmaceutical preparations for the inhibition of tumor necrosis factor alpha and interleukine 1 in mammals at all diseases and conditions where these mediators are excessively secreted. Desirably, the films disintegrate in water and may be formed by a controlled drying process, or other process that maintains the required uniformity of the film. The FET may be electrically connected between an input and an output. Pressure sensing occurs away from the step in a direction of the flow of the fluid in an enhanced turbulence region of the flowmeter where the inner diameter remains enlarged as a result of the step. A processor executes application software and driver software.
