Definitions
- the present invention relates to the field of transdermal drug application systems and relates to an improved device for the administration, by the dermal route, of drug solutes.
- FICK (as well as STOCK and STEIN) according to which the speed of migration is a function of the concentration gradient between two compartments, the molecules going from the most concentrated to the least concentrated.
- the speed decreases when the viscosity of the medium increases or when the permeability is low.
- the reservoir containing the active ingredient solute is closed by a membrane applied to the skin and permeable only to the active ingredient.
- This membrane is covered with an adhesive making it possible to fix the tampon on the skin and to offer a solution of continuity with the latter.
- the tank is replaced by an absorbent mass, a kind of sponge
- the matrix as well as the membrane and the adhesive act as barriers which considerably slow down the migration of the active principle towards the skin.
- the flow of active product which migrates into the skin still has the appearance over time, of an inverted exponential.
- the adhesive which serves as a continuity solution for the migration of the active product requires several hours to adhere, due to the adaptation to the relief of the skin, which creates a delay in the therapeutic effect.
- the adhesive forms a so-called occlusive area on the surface of the skin, that is to say that the adhesive prevents the evaporation of sweat. If the active ingredient is not soluble in water (for example, trinitrine and estradiol), this occlusion effect considerably disrupts, or even prevents, migration. Finally, this same effect is at the origin of the takeoff and the fall of the tampon or lozenge, which can be dramatic for the patient, for example in the event of myocardial infarction.
- the invention aims to eliminate these series of drawbacks and aims to propose a new transdermal application system requiring a set of qualities and advantages not achieved to date, including in particular: effectiveness; reliability at low cost; the absence of adhesive on the part of the skin receiving the active product; obtaining self-regulating flow despite variations in skin permeability (over time and depending on the patient) and the possibility of regular deposition of active product for a period of 8 days, 15 days or more.
- the device according to the invention for the administration by the transcutaneous route of medicinal solutes is essentially characterized in that it comprises: a) a reservoir or application bowl, the base of which is provided with an orifice filling for the solute as well as a cutout with cap provided on its periphery with micro-recesses for the distribution of the solute on the skin; b) means for pressurizing and regulating the flow of solute inside the tank; c) a cover for sealing said tank.
- the micro-recesses are formed by the roughness obtained when the plug is produced by molding the electro-erosion technique.
- roughness indices can be adopted which can vary between No. 33 and No. 21, which corresponds to maximum distances or heights between the peaks or troughs of the recesses from 4.5 to 1.2 microns.
- the stopper has a generally conical configuration in which a conical head can be provided, the first diameter of which corresponds to the diameter of the body of the stopper.
- the micro-recesses are constituted by a notch on the stopper constituting a mini-notch formed parallel to the axis of the stopper and forming an annular channel which ends, on the side in contact with the skin, by a flare whose shape is substantially triangular.
- the active principle of solute through 1 "echancrur circulates around the perimeter of the perimeter capillary then broadcasts on 1'ensemble of the area covered.
- the pressure means is constituted according to a first variant by a balloon based on a plastic film complex and filled with a mixture of freons.
- This balloon or hollow volume is advantageously - although not exclusively - constituted by a polyethylene film bonded to a polyamide film by means of an adhesive constituted, for example, by a two-component polyurethane adhesive.
- this balloon can be replaced by a film, simple or complex above, of plastic material not constituting a volume.
- a seal intended both to ensure the seal and to exert pressure on said film during closing. of the device.
- the balloon contains a mixture of freons which is either in the gaseous state or in the liquid state depending on the conditions of use (application of the tablet or storage of the latter in the cold).
- said mixture liquid at ordinary temperature, is deposited on the internal wall of the reservoir.
- freons freon 11 and freon 113, in substantially equal proportions.
- the pressure means can also be constituted according to a second advantageous variant of the invention by a spring resting on a plastic film.
- Fig. 1 a general view, in section, of a device according to the first alternative embodiment
- - Fig. 2 another embodiment of the internal part of the device
- - Fig. 3 a top view of the device
- - Fig. 4 and 5 representations, respectively in perspective and in section, of a plug with rough walls, obviously provided with a microphone
- - Fig. 6 a representation of a notch for flow, made on one edge of the plug
- - Fig. 7 an enlarged embodiment of a widening of a notch in the form of an equilateral triangle
- a device essentially comprises: a reservoir 1 or application cup, into which a balloon or a plastic film 2 is introduced, and a lid 3 for sealing .
- the wall of the reservoir is provided with a filling orifice 4 (with closure cap, not shown) and with a plug 5 of conical shape.
- FIGS. 4 and 5 illustrate an advantageous embodiment of a plug 5 provided with a conical head and the external faces of which are provided with roughness 13 obtained during electro-erosion molding and corresponding to roughness indices, for example between the n ° 39 and 21.
- a pressure medium intended to slightly compress, under a pressure which can vary for example from 5.10 3 to 5.10 4 Pascals (Pa), the medicated solution on the stopper 5 and force the latter to flow through the roughness 13 or to engage in the notch 6.
- this means is constituted by the balloon 2 made of plastic film welded on the edges and cut in a circle.
- the plastic film is advantageously constituted by a complex based on polyethylene bonded to the polyamide film with a polyurethane adhesive.
- the inner periphery of the cover 3 is provided with a seal 10, for example made of silicone, intended to seal and to wedge a plastic film 11 playing the role of balloon. The cover then acts here as one of the walls of the balloon.
- the solute tank 1 provided with a conical cap 5, and an opening for filling (located at the rear of said plug and not shown in the figure), constitutes the bearing surface of a bellows (15), made of folded plastic film (or possibly in the form of a balloon).
- a bellows made of folded plastic film (or possibly in the form of a balloon). The gradual release of the solute is done by the permanent support of the spring (14) on the bellows (15).
- each constituent element of the device according to the invention takes a similar shape, extra flat and can be made of plastic material by compression molding, using the electro-erosion technique, as said above, for the impressions of the plug and surface roughness or, depending on the variant, the notch.
- the device is often provided with adhesive parts 12 and 17 for attachment to the skin. But it can be used in other forms such as for example in the form of a bracelet or even a belt for application to the abdomen (in particular for the trinitrin solutions used as coronarodilators in 1 • myocardial infarction). It is of course possible to produce the device of the invention according to various dimensions. By way of nonlimiting example, experiments have been carried out according to the first embodiment of FIGS.
- the systems according to the invention are self-regulating.
- the surface of the skin which will absorb the solute will be all the smaller, the higher the permeability of the skin to the active principle.
