  • Publication number: 20220226359
    Abstract: Drug tablets that include a controlled release layer of a moisture-sensitive active agent are prepared with a lipidic matrix forming excipient, a water-soluble, channel forming excipient and a filler, each being non-hygroscipic. The tablets are formed in a process where the components are blended in the absence of moisture and in particulate form.

  • Publication number: 20210378964
    Abstract: Formulations are provided for the oral administration of avanafil, a Type V phosphodiesterase inhibitor (“PDE V inhibitor”), and analogs thereof. The formulations are orally disintegrating tablets (ODTs) that rapidly dissolve or disintegrate in the oral cavity. The tablets contain an absorption enhancing composition that increases the duodenal absorption of the active agent, following transfer from the low pH environment of the stomach to the more basic pH of the duodenum. Methods for administering the active agent using the dosage forms are provided. The invention also encompasses a method of selecting components and compositions to incorporate in the formulations which will facilitate increased absorption of the active agent in the duodenum and thus serve as “absorption enhancing compositions” herein. Also provided are methods for manufacturing orally disintegrating tablets to optimize the physical properties of the dosage forms, particularly hardness and disintegration time.

  • Patent number: 6788111
    Abstract: A one transistor, non-volatile programmable switch comprises a first node and a second node coupled with corresponding circuit elements in an integrated circuit. A single, non-volatile programmable transistor having a drain coupled to one of the first node and second node, a source coupled to the other of the first node and second node, gate coupled to an energizing conductor, the data storage structure constitute the programmable switch. The non-volatile programmable transistor consists of a mask programmable ROM cell, or a charge programmable device, in which the data storage structure comprises a floating gate or a nitride layer, or other charge trapping layer, between oxides or other insulators.

  • Patent number: 6545504
    Abstract: A one transistor, non-volatile programmable switch having four operating states for connection between circuit elements and passive elements including bus lines and input/output pads. The four states include a first unidirectional state in which the cell allows signal flow in a first direction, a second unidirectional state in which the cell allows signal flow in a second direction, opposite to the first direction, a third state in which the cell allows bi-directional signal flow, and a fourth state resenting high impedance in which signal flow is blocked (the switch is open). A non-volatile programmable transistor having a drain coupled to one of the first node and second node, a source coupled to the other of the first node and second node, a gate coupled to an energizing conductor, and a data storage structure constitute the programmable switch.
