Patent Number: 8,066,661

Title: Viscous formulations and their use in needle-free injection

Abstract: Formulations are described that are viscous and will benefit from needle-free delivery at high driving pressures. Conventional delivery of these viscous formulations by hypodermic syringes is inconvenient as well as painful. Formulations include those which have a viscosity of about 5 cS or more at about C. and which can have 0.5 ml or more administered by a needle-free injector in about 0.1 second.+-.0.02 seconds.
