Abstract

The invention relates to medicinal pins for the dermal or transdermal administration of active substances with improved bioavailability. The medicinal substance is released from the medicinal pins and is transported into the skin by an electrical field.

Description

Gegenstand der Erfindung ist ein Arzneistift zur dermalen oder transdermalen Applikation mit verbesserter biolo­ gischer Verfügbarkeit der Arzneistoffe.The invention relates to a medicinal pen for dermal or transdermal application with improved biolo availability of drugs.

Zur dermalen oder transdermalen Applikation von Arznei­ stoffen werden in einem großen Umfang Arzneiformen wie z.B. Salben, Cremes, Gele und Pflaster eingesetzt. Ebenso sind arzneistoffhaltige Arzneistifte bekannt. Arzneistifte können z.B. zur Behandlung lokaler Haut­ veränderungen eingesetzt werden. Eine Anwendung von Arzneistiften zur dermalen und transdermalen Wirkstoff­ applikation ist möglich.For dermal or transdermal application of medication Pharmaceutical forms such as e.g. Ointments, creams, gels and plasters are used. Drug sticks containing medicinal substances are also known. Medicinal pens can e.g. for the treatment of local skin changes are used. An application of Drug pens for dermal and transdermal active ingredient application is possible.

Alle bisher bekannten Arzneistifte weisen den entschei­ denden Nachteil auf, daß die Wirkstofffreisetzung aus ihnen und die anschließende Permeation des Arzneistoffs aus dem Arzneiträger in die Haut ungerichtet durch pas­ sive Diffusion erfolgt. Wirkstoffe, die kein ausreichen­ des Permeationsvermögen durch die Haut aufweisen, können den Wirkort nicht erreichen.All previously known medicinal pens have the decisive factor end disadvantage that the drug release from them and the subsequent permeation of the drug from the drug carrier into the skin undirected by pas sive diffusion takes place. Active ingredients that are not enough of permeability through the skin do not reach the place of action.

Dieser Nachteil wird durch die vorliegende Erfindung dadurch beseitigt, daß der Arzneistoff aktiv aus dem Arzneistift mit Hilfe eines elektrischen Stroms frei­ gesetzt wird. Dadurch kann gleichzeitig auch der gerich­ tete aktive Transport des Wirkstoffes in die Haut, bzw. durch die Haut erfolgen.This disadvantage is overcome by the present invention eliminated in that the drug actively from the Drug stick released with the help of an electric current  is set. This also allows the court active transport of the active ingredient into the skin or through the skin.

In der Abbildung ist ein nichtbeschränkendes Beispiel für den erfindungsgemäßen Aufbau des Arzneistiftes wiedergegeben.The illustration is a non-limiting example for the construction of the medicinal stick according to the invention reproduced.

Der Stift besteht im vorliegenden Beispiel aus einem Griff­ teil, der durch eine in ihm enthaltene Batterie (2) als Kathode polarisiert wird. Der Griff (1) besteht aus Alu­ minium. Der Arzneistoff befindet sich in einem Hydrogel- Arzneiträger (3), der dazu bestimmt ist, auf die zu behan­ delnde Stelle der Haut, z.B. bei der Anwendung von Anti­ histaminika nach Insektenstichen, aufgebracht zu werden. Der Arzneiträger wird durch die Batterie als Anode po­ larisiert.The pin in the present example consists of a handle, which is polarized by a battery ( 2 ) contained in it as a cathode. The handle ( 1 ) is made of aluminum. The drug is in a hydrogel drug carrier ( 3 ) which is intended to be applied to the area of the skin to be treated, for example when using anti-histamines after insect bites. The drug carrier is polarized by the battery as an anode.

Bei der Anwendung des Arzneistifts zur Behandlung von Hautveränderungen am linken Arm wird der Stift mit der rechten Hand am Griff gehalten und mit dem Gelträger auf die zu behandelnde Stelle aufgesetzt. Der Stromkreis wird durch den Arzneistift und den Körper des Patienten gebildet. Die Funktion des Systems wird bei Anwendung über eine elektronische Schaltung (4) angezeigt.When using the medication pen to treat skin changes on the left arm, the pen is held by the handle with the right hand and placed on the area to be treated with the gel carrier. The circuit is formed by the drug stick and the patient's body. The function of the system is indicated by an electronic circuit ( 4 ).

Claims (4)
