  • Peripheral circulatory disorders in the extremities are often accompanied by numbness in the extremities, severely restricted mobility and swelling.
  • the severity of circulatory disorders is very different and can have different causes.
  • Frequent vasospastic attacks are treated with calcium antagonists or nitro compounds, which can lead to improved blood circulation due to their vasodilatory effects.

  • ointment base e.g. B. ground with lanolin
  • the trituration thus obtained is made up to 10 kg with lanolin or another ointment base, stirred vigorously and passed over the roller mill for homogenization.
  • This homogeneous mass is filled in m tubes. The tubes are folded and closed with a special machine.
  • a patient with diagnosed secondary Raynaud's disease i.e. with severe circulatory disorders of the fingers, was treated with a formulation according to Example 1 for 4 weeks.
  • the ointment was applied to the skin and was able to act for about 9 hours during the night. After a few days, the hands were functioning normally, i.e. the numbness of the fingers, their severely restricted mobility and the swelling had disappeared.
  • the ointment was applied to the hand regularly throughout the day. After three weeks the wounds were closed, the fingers were painless and the hand was functional.
