Abstract: Stable pharmaceutical compositions of descarboethoxyloratadine (DCL), a metabolic derivative of loratadine, for the treatment of allergic rhinitis and other histamine-induced disorders are disclosed. The compositions are formulated to avoid the incompatibility between DCL and reactive excipients such as lactose and other mono- and di-saccharides. Disclosed compositions include lactose-free, non-hygroscopic and anhydrous stable pharmaceutical compositions of DCL.

Abstract: A voltage generation circuit includes a voltage pump that receives a supply voltage and develops an output voltage responsive to a pump activation signal. A level detection circuit receives a pump-boost signal and is coupled to the voltage pump to receive the output voltage. The level detection circuit operates in a normal mode responsive to the pump-boost signal being inactive to develop the pump activation signal to activate the voltage pump responsive to the output voltage being less than or equal to a first low threshold value. The level detection circuit operates in a demand-controlled mode responsive to the pump-boost signal being active to develop the pump activation signal to activate the voltage pump responsive to the output voltage being less than or equal to a second low threshold value.

Abstract: A regulator circuit with at least two independently selectable and adjustable adjustment circuits. Each adjustment circuit may be connected across a standard voltage divider circuit used to create a reference voltage for operating a voltage pump. Between each adjustment circuit and the voltage divider circuit is an associated connection circuit that is controlled by an associated control signal. When activated by its respective control signal, the connection circuit connects its associated adjustment circuit to the voltage divider circuit so that the reference voltage is generated by the voltage divider as adjusted by the connected adjustment circuit. The amount of adjustment each adjustment circuit can introduce is independently selectable, the regulator circuit can adjust the operation of the pump for different modes of operation and can compensate for process variations without the need to re-design, re-mask or re-fabricate the circuitry.
