  • Patent number: 11471470
    Abstract: The present invention provides for bioavailable oral dosage forms containing esters of 17-hydroxyprogesterone as well as related methods. The oral dosage forms can be formulated for pregnancy support and can include a therapeutically effective amount of an ester of 17-hydroxyprogesterone and a pharmaceutically acceptable carrier. In another embodiment, a pharmaceutically acceptable oral dosage form for pregnancy support is provided. The pharmaceutically acceptable oral dosage can include a therapeutically effective amount of an ester of 17-hydroxyprogesterone and a pharmaceutically acceptable carrier. The oral dosage form can, when measured using a USP Type-II dissolution apparatus in 900 mL of deionized water with 0.5 (w/v) of sodium lauryl sulfate at 50 RPM at 37° C., release at least 20 wt % of the dose of the ester of 17-hydroxyprogesterone after 60 minutes, or in the alternative release at least 20 wt % more after 60 minutes than an equivalently dosed oral dosage form without the carrier.

  • Patent number: 11433083
    Abstract: The present disclosure is drawn to pharmaceutical compositions and oral dosage capsules containing testosterone undecanoate, as well as related methods. The capsule includes a capsule shell and a capsule fill. The capsule fill can include a solubilizer and about 14 wt % to about 35 wt % testosterone undecanoate based on the total capsule fill. The oral dosage capsule is such that when a single oral administration to a male subject of one or more capsules with a total testosterone undecanoate daily dose of about 350 mg to about 650 mg it provides a ratio of serum testosterone Cmax to serum testosterone Cave of about 2.7 or less. In yet another embodiment, a method for providing a serum concentration of testosterone within a target serum testosterone concentration Cave range for a male subject is provided.

  • Patent number: 11436049
    Abstract: Systems, apparatuses, and methods for controlling bandwidth through shared transaction limits are described. An apparatus includes at least a plurality of agents, a plurality of transaction-limit (T-Limit) nodes, a T-Limit manager, and one or more endpoints. The T-Limit manager creates a plurality of credits for the plurality of agents to send transactions to a given endpoint. Then, the T-Limit manager partitions the credits into N+1 portions for N agents, wherein the extra N+1 portion is a shared pool for use by agents when they run out of their private credits. The T-Limit manager assigns a separate private portion of the N portions to the N agents for use by only the corresponding agent. When an agent runs out of private credits, the agent's T-Limit node sends a request to the T-Limit manager for credits from the shared pool.

  • Publication number: 20210342282
    Abstract: A system and method for efficiently arbitrating traffic on a bus. A computing system includes a fabric for routing traffic among one or more agents and one or more endpoints. The fabric includes multiple arbiters in an arbitration hierarchy. Arbiters store traffic in buffers with each buffer associated with a particular traffic type and a source of the traffic. Arbiters maintain a respective urgency counter for keeping track of a period of time traffic of a particular type is blocked by upstream arbiters. When the block is removed, the traffic of the particular type has priority for selection based on the urgency counter. When arbiters receive feedback from downstream arbiters or sources, the arbiters adjust selection priority accordingly. For example, changes in bandwidth requirement, low latency tolerance and active status cause adjustments in selection priority of stored requests.
