Abstract: Pharmaceutical formulations comprise a mono- or di-aminopyridine active agent for administration on a once- or twice-daily basis for use in the treatment of neurological diseases, in particular multiple sclerosis and Alzheimer's disease. The formulations, which are suitable for oral or percutaneous administration of the active agent, include the active agent in a carrier effective to permit release of the mono- or di-aminopyridine at a rate allowing controlled absorption thereof over, on the average, not less than a 12 hour period and at a rate sufficient to achieve therapeutically effective blood levels over a period of 12-24 hours following administration.

Abstract: A preparation for the once-daily, percutaneous administration of nicotine comprises nicotine uniformly distributed in a solid, semi-solid or mucilaginous medium which can be placed in intimate contact with the skin, the solid, semi-solid or mucilaginous medium is formed by adding a given amount of nicotine to a solution of a solidifying or gel-forming agent or mixture thereof in a suitable solvent or mixture of solvents and mixing or heating the mixture thereby obtained so as to form the solid, semi-solid or mucilaginous medium. The preparation can be used in a method of treating withdrawal symptoms associated with smoking cessation and for combating the psychological dependence that occurs through frequent smoking.

Abstract: A transdermal device having a detachably mounted electrode with a first surface adapted for contact with human skin and through which a drug substance contained in the electrode passes to the skin under the influence of an iontophoretic or electro-osmotic force and a second surface which is electrically conducting, the electrode has a surface area in contact with the skin, in use, in the range 0.1 to 30 cm.sup.2 and a drug dissolved or dispersed in a hydrophilic medium at a concentration in the range 0.1 to 15% (w/v) based on the hydrophilic medium.

Abstract: A method of using nicotine in the treatment of various conditions susceptible to alleviation by nicotine therapy such as disease states characterized by reduced central cholinergic function. Nicotine is administered to a subject initially having a blood supply substantially free of nicotine at a dose and for a period sufficient to allow the subject to tolerate the dose and thereafter increasing the dose of nicotine at intervals until a therapeutic dose is achieved. Smokers may also benefit from the treatment regimen.
