Abstract: This invention relates to sulfur-substituted phenylacetamides of the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 may be the same or different and are H or CH.sub.3 ; R.sub.4 is SR.sub.5, ##STR2## R.sub.5 and R.sub.6 may be the same or different and are lower alkyl containing 1-4 carbon atoms and R.sub.5 and R.sub.6 may be taken together with S to form a 5-7 member ring; and X.sup.- is a pharmaceutically acceptable anion, which exhibit arrhythmia activity.

Abstract: A method of enhancing transdermal delivery of a pharmaceutically active drug from a transdermal delivery system as well as a transdermal delivery system capable of providing a desirable flow interface between the delivery system and the skin surface are disclosed. The method involves pre-treating an area of skin with an anticholinergic agent in an amount sufficient to have a local antisecretory effect on the area treated, such amount being insufficient to cause systemic effects; and applying the transdermal delivery system to the pre-treated area. The delivery system of the present invention is comprised of a carrier means, a pharmaceutically active drug and an anticholinergic agent. With both the method and the delivery system, the anticholinergic agent is preferably a quaternary ammonium salt which is itself transdermally delivered to the area beneath the delivery system in an amount sufficient to suppress perspiration in that area.

Abstract: Pharmaceutical preparations comprised of a pharmaceutically active ingredient and a carrier which comprises a percutaneous penetration enhancer comprised of 2-ethyl-1, 3-hexanediol alone or in combination with oleic acid is disclosed. The 2-ethyl-1, 3-hexanediol may be present in an amount in the range of about 50% to 100% based on the weight of the carrier. The oleic acid may be used in combination with 2-ethyl-1, 3-hexanediol in an amount of about 1 to 40% based on the weight of the carrier to provide a synergistic effect with respect to percutaneous penetration enhancement. The compound 2-ethyl-1, 3-hexanediol as used alone and/or in combination with the oleic acid has been found to significantly enhance the delivery of a drug, to a patient, from a transdermal delivery system.

Abstract: A method of inducing short-term pupil diameter enlargement and reducing intraocular pressure in animals without significant systemic effects is disclosed. There is provided a site-specific chemical delivery method for topically applying to the eye of an animal, an effective ophthalmologically acceptable amount of an adrenalone diester of the general formula: ##STR1## wherein R prepresents a member selected from the group consisting of hydrogen or a C.sub.1 -C.sub.3 straight alkyl group; and wherein R.sub.1 and R.sub.2 independently represent an acyl group or derivative thereof; or an opthalmologically acceptable acid addition salt thereof. The method allows the pupil diameter to be enlarged for a short period after which the pupil returns to normal and thus restores normal eye sight.
