Definitions
- the present invention which relates to the use of apocodeine (APC) and/or its derivatives for the preparation of various medicinal forms (patches, tablets, sprays), overcomes the current limitations of the treatment in use for treating the pathologies under consideration, since, in the forms and doses proposed, APC is effective, is free of side effects and requires only simple and cost-effective technology for its preparation.
- APC apocodeine
- compositions for the treatment of male impotence and for the stimulation of male and female libido.
- APC apocodeine
- the molecule APC and its derivatives are stable with respect to air and light.
- APC is a powerful drug which can be administered transdermally.
- the active principle (APC) is rapidly absorbed, becomes effective rapidly (latency time 8 ' -18 ' ) and is equally rapidly eliminated (half-life 30').
- TDDS transdermal drug delivery system
- a subject of the present invention is thus a pharmaceutical composition comprising, in pharmaceutically acceptable and effective doses, APC and/or its derivatives.
- a further subject of the invention is a transdermal patch comprising, as active principle, APC and/or its derivatives, this patch having a type I, type II or type III structure, and its shape and size being suitably sized in relation to the site of application and the desired dosage.
- a further subject of the invention is the use of APC and/or its derivatives, for the preparation of a transdermal patch for the treatment of male impotence and for the stimulation of male and female libido.
- TYPE I is a device comprising an impermeable support film on which is a matrix or reservoir in which the active substance is dissolved and/or dispersed.
- the matrix on the side opposite the support, is coated with a membrane which is permeable to the active substance and regulates its cross-flow.
- a contact adhesive is layered on the free side of the permeable membrane (adhesive layer) , protected by a release strip.
- the device is used as follows: the release strip is pulled off and the device is positioned over the desired part of the patient's body and applied with light pressure.
- TYPE II This device comprises an impermeable support film on which is a matrix or reservoir in which the active substance is dissolved or dispersed. It lacks the membrane which is permeable to the active substance, which modulates the cross-flow, as a result of which the matrix is free on one side and comes into direct contact with the epidermis.
- the adhesive is located around the edge of the device, as a kind of adhesive ring. The assembly is protected on the free side by a single removable release strip, as in type I.
- the device is used as follows: the release strip is pulled off and the device is positioned over the desired part of the patient's body and applied with light pressure.
- TYPE III This is also known as a "drug in an adhesive matrix" assembly.
- the pharmacological dose is housed directly, in dissolved or dispersed form, in the adhesive, which thus also acts as a reservoir matrix and is layered on an impermeable support film.
- the adhesive matrix is protected on one side by the support (backing) , and on the other side by the release strip.
- the device is used as follows: the release strip is pulled off and the device is positioned over the desired part of the patient's body and applied with light pressure.
- the preferred patch is the type III patch, and more preferably the type III patch with acrylic adhesives, in rectangular shape when it is desired to achieve constantly high doses for long periods, or in anatomical shape when a targeted rapid result is desired (e.g. treatment of sexual impotency) .
- Fig. 1 is a graph of the accumulation of APC over time.
- Fig. 2 is a graph of the flow of APC over time
- Fig. 3 is the approximate curve representing the levels in human plasma at the times indicated, relative to the APC active principles.
- the active principle APC or a derivative thereof is incorporated simultaneously with the other components (stabilizer, permeation activators, etc.) into the hot adhesive solution and is homogenized by stirring until the liquid adhesive matrix or reservoir is formed;
- the blade of a knife is mounted across the entire width of the conveyor belt of the laminating machine on which the release strip is solidly positioned;
- the "thready" adhesive matrix is poured in front of the blade which, as the conveyor belt advances, distributes a uniform layer (lamination) of adhesive matrix over the release strip;
- the thickness of the layer is determined mainly by the distance between the edge of the knife blade and the release strip passing underneath it;
- the process described allows the removal of the solvent, thus avoiding its occlusion by the rapid formation of a surface crust.
- the support film (backing) is affixed.
- Adhesive matrix formulation
- antioxidant sodium metadisulphite, EDTA disodium salt
- solubilizing agent a glycol
- acrylic resin to improve the cohesive force • acrylic resin to improve the cohesive force: cationic copolymers based on dimethylaminoethyl methacrylate and methacrylic esters
- surfactant SDS (sodium dodecyl sulphate);
- pressure-contact adhesive mixture of two adhesives, A and B, in which A is an acrylic contact adhesive of average molecular weight which is not self-bonding, with a high interlacing index, a dermal irritation index of 0.20, classified as "minimally irritant” and containing 100% ethyl acetate as solvent; and B is an acrylic adhesive of high molecular weight, which is self-bonding, with a moderate interlacing index, a dermal irritation index of 0, classified as "non- irritant” and containing a mixture of ethyl acetate, isopropanol, hexane and toluene as solvent.
- Release strip The release strip is a polyester film laminated with silicone on one side (the side facing the adhesive matrix) . The thickness is approximately 125 ⁇ m.
- the backing is a laminated, clear, occlusive polyester film with a heat-welding layer.
- the total thickness is approximately 51 um.
- APC APC or its derivatives
- APC/C batch with addition of permeation inducers, 0.5% active principle in the matrix (all of the drug is dissolved) : 1 ) APC/C 0 . 50%
- the skin permeability of APC is sufficient per se and can be increased or decreased by means of various permeation activators such as fatty acids or alcohols. All of the in-vitro permeation studies were carried out on models using guinea-pig skin, which we know has comparable permeability to that of human skin and which gives more reproducible results than the latter.
- the chemical stability of APC in the formulation of the patch is achieved by adding an antioxidant (sodium metabisulphite) and is demonstrated by means of a 15-day accelerated stability test at 40°C and 75% RH (relative humidity) .
- the surfactant (SDS) is added to dissolve most of the APC, since only the dissolved APC is available for release and permeation.
- the patches also demonstrated good physico- chemical properties, which can be optimized by those skilled in the art for the purposes of adhesion at the site of application and tolerability by the individual undergoing the treatment, without modifying the rate of permeation of the active principle.
- compositions comprising apocodeine and/or its derivatives for the treatment of male impotence and for the stimulation of male and female libido.
- APC is a powerful drug which can be administered orally.
- the active principle is rapidly absorbed, becomes effective rapidly (latency time 8'-18') and is equally rapidly eliminated (half-life 30').
- APC active principle
- composition active principle APC 150 mg
- Excipients corn starch 8 mg tribasic citrate 43 mg magnesium stearate 2 mg total 200 mg
- B the dose/effect ratio for induction of the penile erection (PE) activity by means of oral apocodeine (APC) in rats.
- the rats received apocodeine solution or saline solution.
- the animals were counted in accordance with a double-blind experimental plan.
- the penile erections were recorded continuously.
- PEI penile erections
- the number of animals is given in parentheses
- the effective dose is between 10 and 40 mg/kg, the optimum being 20 mg/kg.
- compositions comprising apocodeine and/or its derivatives for the treatment of male impotence and for the stimulation of male and female libido.
- APC is a powerful drug which can be administered orally in the form of a spray.
