  • Patent number: 9066942
    Abstract: The disclosed invention is drawn to pharmaceutical tablets that provide delivery of active agents having at least three oxygen-containing groups, as well as a second active ingredient. Non-limiting examples of three oxygen-containing group active agents include guaifenesin, codeine, hydrocodone, and their pharmaceutically acceptable salts. In one embodiment, a pharmaceutical tablet for oral administration once every 12 hours is provided. The tablet includes a first active agent that is a tri-oxy active agent, a second active agent, and a release rate controlling non-ionic oxyl-containing hydrophilic polymer. The total oxyl content of the hydrophilic polymer in the tablet is about 4×10?4 moles to about 2.0×10?3 moles.

  • Publication number: 20150165049
    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: 9034858
    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.
