摘要:
The present disclosure generally related to an improved process for the preparation of various piperidine derivatives. More particularly, the present disclosure related to an improved process for preparing sufentanil base (1) and related compounds, which advantageously utilizes more cost effective and/or less hazardous reagents, including a dispersion comprising between about 50% and about 70% by weight (based on the total weight of the dispersion) of an alkali metal hydride, such as sodium hydride, as well as eliminates the need for expensive and/or time consuming purification techniques.
摘要:
The present invention provides (+)-morphinanium compounds comprising substituted 6-hydroxy or 6-amine groups. The invention also provides methods for inhibiting microglial activation by administering the compounds of the invention.
摘要:
A dual head contrast media injection system performs a patency check or test injection, determining flow rate and/or flow volume from the programmed protocol. The tubing that connects syringes to a patient shares only a short common section near to the patient. Appropriate injection steps are taken to compensate for tubing elasticity. A wireless remote control and a touch screen control are provided, improving functionality and information delivery. The display brightness is controlled based on the ambient light, and the display panel includes a double swivel permitting re-orientation. The orientation of the display may also be controlled based on, e.g., the current step, the tilt angle of the powerhead, or a manual control. Furthermore, the display is customizable to identify the type of fluid (contrast, saline, etc.) on either side of the injector, to provide matched color coding, and to provide a folder/tab analogy for retrieving injection protocol parameters.
摘要:
A system for assaying an eluate for Technetium-99m and Molybdenum-99 content includes an inner ionization chamber including a well configured to receive the eluate, an outer ionization chamber concentric with the inner ionization chamber, and attenuating material positioned between the inner and outer ionization chambers. A computing device is configured to determine a Technetium-99m content of the eluate based on a first current measured in the inner ionization chamber, and determine a Molybdenum-99 content of the eluate based on at least a second current measured in the outer ionization chamber.
摘要:
An elution tool for a radiopharmaceutical elution system includes an elution tool. The tool has a vial chamber sized and shaped for receiving an elution vial. An access opening is aligned with a septum of the elution vial when the elution vial is received in the vial chamber. An elution tool lid is secured to the elution tool body by a hinged connection. The elution tool lid is rotatable at the hinged connection and movable relative to the elution tool body between an occluded position and an exposed position. The tool also includes a latching mechanism for selectively and releasably locking the lid in the occluded position.
摘要:
A foot-activated controller (70) for an imaging system (10) is disclosed. The foot-activated controller (70) may include a first controller section (80) and a second controller section (90) that may be disposed in each of a joined or separated state or configuration. The first controller section (80) may incorporate one or more first actuators (86) that are dedicated to communicating with one or more components that provide an imaging functionality (e.g., an imaging assembly (12)), while the second controller section (90) may incorporate one or more second actuators (96) that are dedicated to communicating with one or more components that provide a physical positioning functionality (e.g., a table positioner 38, where the table positioner (38) may be activated to control/establish the position of a table (32) on which a patient may be positioned for performance of one or more medical procedures (e.g., urology)).
摘要:
Systems and methods for tracking dosage periods are disclosed. The systems and methods may include setting a timer (140) to a predetermined value corresponding to a dosage period in response to the engagement of a cover (110) to a container (120). An indication may be provided that corresponds to a remaining period in the dosage period set by the engagement of the cover (110) and container (120). The indication may also indicate a remaining time period in the dosage period.
摘要:
The present disclosure provides pharmaceutical compositions comprising an opioid and an additional active pharmaceutical ingredient, wherein the composition exhibits gastric retentive properties which are achieved by a combination of a physical property of the composition and release of the opioid, wherein upon administration to a subject, the composition has at least one pharmacokinetic parameter that differs by less than about 30% when the subject is in a fasted state as compared to a fed state. The present disclosure further provides pharmaceutical composition comprising oxycodone and acetaminophen that provides a rapid onset of analgesia, and reduced levels of acetaminophen near the end of the dosing interval. Also provided are an extended release pharmaceutical composition comprising oxycodone and acetaminophen that provides reduced abuse potential.
摘要:
A holder for a vial containing a sterile liquid for use with a radiopharmaceutical elution system includes a holder body. The body has a top, an opposing bottom, an opening in the top and a vial chamber. The vial chamber extends from the opening in the top toward the bottom and is sized and shaped for receiving the vial therein. An access opening extends through the bottom to the vial chamber and is aligned with a septum of the elution vial when the sterile vial is received in the vial chamber. A cap is removably secured to the top of the holder body for selectively opening and closing the vial chamber. The holder body includes plastic and has a density less than the density of the cap.
摘要:
A solid composition comprises: MnO2; and a compound represented by the general formula (I) wherein: R is a polymer; each Y is independently a hydrogen or a negative charge; Z is either hydrogen or is not present; each n is independently 1, 2, 3, 4, 5 or 6; wherein the MnO2 is bound to the compound of formula (I) so as to coat the surface thereof. Such a composition may be used for the separation of polyvalent metal species, such as Mo, from one or more accompanying impurities.
