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 20° C. and which can have 0.5 ml or more administered by a needle-free injector in about 0.1 second±0.02 seconds.
