Abstract: Essentially sodium-free effervescent solid pharmaceutical compositions The present invention relates to an effervescent solid pharmaceutical composition, which is essentially free of sodium content, comprising: a therapeutically effective amount of an active pharmaceutical ingredient; one or more pharmaceutically acceptable alkaline earth metal carbonates or hydrogencarbonates in an amount from 1 to 31% by weight of the composition; and one or more pharmaceutically acceptable acids, pharmaceutically acceptable acid salts, or alternatively, a mixture thereof, in an amount from 2 to 62% by weight of the composition; together with one or more pharmaceutically acceptable excipients or carriers; wherein, the total content of the ion sodium in the effervescent solid pharmaceutical composition is equal to or lower than 1 mmol. It also relates to processes for its preparation and its use in therapy.

Abstract: A system for hierarchical topological addressing and hierarchical recursive routing in a network includes routing devices organized in a hierarchical topology forming a routing layer including levels. The levels include first and second levels including first and second subsets of the routing devices, respectively. Each routing device in the first level is directly connected to endpoint modules and to routing devices in the second level. Each routing device has a hierarchical address based on a location of the routing device within the hierarchical topology. Each routing device performs recursive one-hop routing to route packets through the network. Performing recursive one-hop routing on a particular packet includes: selecting a network port based on a destination address of the packet, wherein the destination address is a hierarchical address of a second routing device in the first level, and forwarding the packet to a routing device directly connected to the selected network port.
