Abstract: A stable, ready-to-use injectable solution including thiotepa and one or more pharmaceutically acceptable solvents, co-solvents, and/or solubilizing agents. Formulations retain at least 90% and as high as 99% of the purity of thiotepa as measured by HPLC after storage at 25° C./60% RH for a period of 7 days. Certain formulations retain at least 99% of the purity of thiotepa as measured by HPLC after storage for at least six months at 2-8° C.

Abstract: The present application provides a stable, ready-to-use fosaprepitant dimeglumine formulation which is easy to administer without need of any reconstitution step and has a desirable solubility, stability and safety profile. The concentration of the fosaprepitant dimeglumine in the liquid formulation is preferably less than about 80 mg/ml, or more preferably between about 20 mg/ml to about 60 mg/ml. In certain embodiments, the liquid formulation retains at least about 90% chemical stability of the fosaprepitant dimeglumine after storage for a commercially reasonable amount of time at a temperature between about 0° C. to about 40° C.

Abstract: A duty cycle correction circuit has a delay line comprising a plurality of current-starved inverters coupled together in series. An input of a first current-starved inverter receives an input clock signal. A relatively weak inverter is coupled in parallel with each of the current-starved inverters. A low pass filter having an operational amplifier has a differential input coupled to the output of the delay line for receiving an output clock signal. A single-ended output of the operational amplifier is coupled to current source and current sink transistors of each of the current-starved inverters to control the amount of delay provided by the delay line. The low pass filter corrects the duty cycle of the input clock signal so that the output clock signal has a 50 percent duty cycle. The relatively weak parallel-connected inverters insure that no clock pulses are skipped if the current-starved inverters fail to transition.

Abstract: The present invention provides a titratable transdermal drug delivery system comprising an effective dose of an antithrombotic agent, such as tirofiban, or a pharmaceutically acceptable salt thereof. The dosage of the drug delivered is proportional to the size of the patch applied and achieves 60-85% platelet inhibition. The system enables and individualized treatment for patients. Also provided are methods for the treatment of various disorders where platelet inhibition is desired.
