Executive Summary
Vivus has received a US patent for its MUSE drug delivery system for treating erectile dysfunction. The non-invasive system delivers alprostadil, a vasodilator, via the urethra to increase blood flow to the penis and maintain functional blood vessels within the organ. Earlier this year, Vivus, of Mountain View, California, saw sales of its device plunge by 70% as a result of the launch of Pfizer's pharmaceutical, Viagra (see Clinica No 816, p 9).
