Abstract: The present invention is concerned with pharmaceutically acceptable solutions of carvedilol or pharmaceutically acceptable salts thereof containing adjuvants with lipophilic character, with the carvedilol content lying above 5% (wt./wt., based on the solution) and the carvedilol being distributed in the solution as a molecular dispersion, as well as pharmaceutical administration forms containing such solutions and their use for the treatment and/or prophylaxis of illnesses, such as hypertension, cardiac insufficiency or angina pectoris.

Abstract: Microparticles which are less than 12 .mu.m in size and are formed of or comprise a solid lipophilic group-containing compound having an HLB value less than about 20 produce a long lived ultrasonically echogenic entity in aqueous liquid and are useful as left heart ultrasonic contrast image enhancing agents. Contrast media for ultrasonic diagnostics comprising a liquid vehicle containing (a) suspended therein microparticles of a mixture of at least one (C.sub.8 -C.sub.20)-fatty acid and at least one solid that is not a surfactant and (b) microbubbles, are especially effective upon ultrasonic imaging after intravenous administration, for the contrasting of both the right heart and left heart, of the myocardium, as well as other organs, such as liver, spleen, and kidneys.

Abstract: A device for transdermal administration of active medicinal agents is based on the active medicinal agent dissolved to an extent of at least 50% in a nonflowable, physiologically acceptable gel, which latter is distributed in a microdisperse mode in a crosslinked silicone elastomer.

Abstract: A vaginal ring comprises a supporting ring 1 free of active agent. A layer 2, which contains an active agent such as a steroid, is applied on its outer rim, optionally in a continuous groove provided in the supporting ring. This layer, in turn, is coated with a layer 3 devoid of active ingredient. All components preferably comprise an LTV silicone elastomer. The ratio of the thickness of the layer 2, containing an active agent, to the layer 3, free of active agent, is about 5-50:1. As a result, a long-term and uniform release rate is achieved for the active agent.

Abstract: The useful lifetime and the amount of microbubbles of a size less than 50 .mu.m produced by mechanical agitation of an aqueous liquid employed as an ultrasonic contrast medium are increased by employing a liquid containing dissolved therein a tenside which reduces the surface tension of the liquid and a compound which raises the viscosity of the liquid.
