The invention provides Beta-blocker drugs that are chemically modified by covalent attachment of a water soluble oligomer. A conjugate of the invention, when administered by any of a number of administration routes, exhibits a different biological membrane crossing rate as compared to the biological membrane crossing rate of the Beta-blocker drug not attached to the water soluble oligomer.
