  • Patent number: 7018658
    Abstract: Tamsulosin pellets having an advantageous release profile are formed. The pellets have an enteric coating and release less than 10% of the tamsulosin in two hours in SGF.
    Type: Grant

  • Publication number: 20040067254
    Abstract: Paroxetine salt compositions having improved stability are formed by controlling the pH to 6.5 or less. The compositions can be made with the aide of water without significant coloration problems. The paroxetine salts include paroxetine hydrochloride salts but preferably use paroxetine sulfonate salts such as paroxetine methane sulfonate.

  • Patent number: 6638535
    Abstract: Hypnotic pharmaceutical compositions are made from pellets and exhibit a modified release. Zolpidem or a pharmaceutically acceptable salt thereof is a typical hypnotic. The pellets are preferably spherical and exhibit a dissolution profile that includes 60% of the hypnotic agent being release from the pellet not earlier than 5 minutes from the start of a specified in vitro dissolution test. Although the modified release profile can include 50% of the hypnotic agent being released not earlier than 15 minutes after the start of the dissolution test, the pellet preferably does not contain a release rate controlling excipient or coating. Instead, microcrystalline cellulose and the active constitute the majority of the pellet, e.g. 90% or more. Spherical pellets are also made by a convenient method that is applicable to any pharmaceutically active agent.

  • Publication number: 20030147955
    Abstract: Pharmaceutical tablets containing low amounts of a tamsulosin active material are made by a dry process. The tablets, which contain 0.1 to 1.5% tamsulosin active material, can be formed reliably with low variations without the aid of a liquid.
