    • PROBLEM TO BE SOLVED: To provide a method for producing an extremely high-purity galantamine or an extremely high-purity galantamine derivative.
      SOLUTION: The method comprises the following process: the starting material is a racemic bromonarwedine, which is first debrominated under palladium's catalytic action; in this case, reaction mixture treatment is essential, which is conducted in the presence of oxygen or a peroxide so that the palladium catalyst in an insoluble form can easily be converted to such a form as to be easily separated, and a further reaction is conducted by reducing an enantiomerically pure narwedine in order to form an enantiomerically pure galantamine, wherein an alkylation or dealkylation follows so as to attain the corresponding substitution at a nitrogen atom on the ring, and, by further refining the enantiomerically pure galantamine thus formed such as making a recrystallization, residual palladium content of 5 ppm or less is attained, enabling the resultant enantiomerically pure galantamine to be directly used as a pharmaceutical material.

    • The invention relates to a pharmaceutical composition based on an active ingredient that is enclosed in liposomes for topical, transdermal application. The interior of said liposomes comprises an acidic, aqueous medium containing at least one cholinesterase inhibitor, preferably from the group containing donepezil, rivastigmine, galantamine, physostigmine, heptylphysostigmine, phenserine, tolserine, cymserine, thiatolserine, thiacymserine, neostigmine, huperzine, tacrine, metrifonate and dichlorvos, or an enantiomer or derivative of at least one of said compounds. In addition, the invention relates to a method for producing said composition, optionally in a sterile form and also to the use of the liposomes charged with the active ingredient in various galenic formulations for topical, transdermal application with a depot effect in the epidermis, for the prophylaxis and/or treatment of cutaneous neuropathic pain or the loss of cutaneous sensory function as a result of neuropathy.
