Abstract: A pharmaceutical composition for oral administration comprising a free-flowing granular powder comprising diclofenac or a pharmaceutically acceptable salt thereof, a pharmaceutically acceptable substantially non-hygroscopic water soluble diluent, an optional binder, and one or more optional pharmaceutically acceptable excipients, wherein the composition is devoid of any alkalizer, buffer or base. The pharmaceutical composition is divided into unit doses containing a therapeutically effective amount of diclofenac, and may be incorporated into sachets, tablets or capsules. and not less than 85% of the free-flowing granulate powder dissolves after 3 minutes in simulated intestinal fluid at pH 6.8. The pharmaceutical composition is rapidly bioavailable when orally administered to a mammal, e.g., human.

Abstract: Methods, circuitries, and systems for real-time protection of a stack are provided. A stack protection circuitry includes interface circuitry and computation circuitry. The interface is circuitry configured to receive a return instruction from a central processing unit (CPU). The computation circuitry is configured to, in response to the return instruction, generate protection data that i) identifies a new topmost return address location that is below a current protected topmost return address location and ii) specifies read only access for the new topmost return address location. The interface circuitry is configured to provide the protection data to a memory protection unit to cause the memory protection unit to enforce a read only access restriction on the new topmost return address location.
