Definitions
- the present invention relates to compositions and devices for transdermal delivery of S-ketamine.
- the present invention relates to compositions for the iontophoretic delivery of S-ketamine for the treatment of pain or depression.
- TTS Transdermal Therapeutic Systems
- iontophoresis is an active drug delivery system.
- the working principle of iontophoresis is based on the fact that an electric field is generated between two electrodes placed on the skin. Depending on the charge of the active ingredient, it is present in a reservoir in the area of one of the electrodes and is repelled by the electrode closer to the reservoir and attracted by the electrode further away from it. In order to get to this electrode, the active ingredient has to pass the skin barrier and is thus absorbed by the body. However, this process only takes place as long as the electric field exists.
- Iontophoresis does not necessarily have to be used with pharmaceutical active ingredients that have ionized functional groups, as it is also possible, for example, that the active ingredient is entrained in an electrolyte-containing solution.
- the most favorable for iontophoretic administration are electrically charged active ingredients that are moved directly over barriers (e.g. the skin) within an electric field.
- iontophoresis The process of iontophoresis was originally described by LeDuc in 1908 and even earlier in US Patents 222,276 (1879) and 486,902 (1892). Since then, iontophoresis has found commercial use in the delivery of ionically charged therapeutic drugs such as pilocarpine, lidocaine, dexamethanone, lidocaine, and fentanyl.
- the skin contact area of the device and the drug concentration within the device are less important to the amount of drug flow through the skin. Instead, the release of the active ingredient depends largely on the applied current with which the active ingredient is pressed into the skin.
- a typical iontophoretic drug delivery system comprises an electrolytic electrical system comprising an anode and a cathode to be adhered to different, preferably adjacent, areas of skin of a patient, each electrode being connected by a wire to a remote power supply.
- this is an electrical instrument controlled by a microprocessor.
- Such devices including systems with a slim construction, are, for example, in US 5,685,837 or US 6,745,071. Further developed systems are also known in principle to the person skilled in the art.
- iontophoretic transdermal systems for lidocaine and fentanyl are approved in the USA.
- an administration system and in particular an iontophoretic administration system for S-ketamine with which the effective Doses for the treatment of pain or depression can be provided and in which satisfactory pharmacokinetics are achieved with largely suppressing side effects.
- the present invention accordingly relates in a first aspect to an iontophoretic composition which
- a thickener in an amount to set a viscosity of at least 500 mPas (at 20 ° C.), and
- a thickener to set the specified minimum viscosity serves to match a desired ionic strength with which the efficiency of the iontophoretic process can be improved so that effective amounts can be administered for the treatment of pain and / or depression.
- the active ingredient ketamine is present in the iontophoretic composition according to the invention as a salt and preferably as a salt of “S-ketamine” (see below) in which the amine nitrogen atom is protonated.
- Suitable anions for such salts are, for example, chloride, bromide, iodide, sulfate, phosphate, lactate, citrate, tartrate, salicylate, succinate, maleate, gluconate, mesylate, laurate, dodecylate, myristate, palmitate, stearate, coconoate, behinate, oleate, linoleate , Linolenate, eicosapentaenoate, eicosahexaenoate, docosapentaenoate, docosahexaenoate, eicosanide and the like. Most preferred is the chloride salt.
- the ketamine content should expediently be such that an effective amount of ketamine can be administered over a longer period of time, such as, for example, 2 to 12 hours or 4 to 8 hours.
- a sufficient amount of the active ingredient must be dissolved in the composition so that the concentration of the ketamine must not be set too low.
- the ketamine salt cannot be dissolved in any amount in the iontophoretic composition.
- the iontophoretic composition according to the invention contains cations which are not due to protonated ketamine in a concentration in the range from about 0.05 to about 1.5 mol / l, in particular from about 0.1 to 1.0 mol / l , more preferably about 0.12 to about 0.8 mol / l and even more preferably about 0.15 to 0.7 mol / l.
- the cations can be based on dissolved pharmaceutically acceptable organic or inorganic salts (e.g. sodium chloride), or they can be provided by protonation or deprotronation of thickeners or other additives in the composition that have appropriate groups.
- the iontophoretic composition according to the invention has an ionic strength of the ions not attributable to ketamine salts in the range from about 0.05 to about 1.5 mol / l, in particular from about 0.1 to 1.0 mol / l, more preferably about 0.12 to about 0.8 mol / l and even more preferably about 0.15 to 0.7 mol / l.
- Suitable thickeners for the purposes of the present invention are, for example, neutral thickeners, such as those based on polysaccharides.
- neutral denotes the fact that the thickeners do not have any ionic groups.
- Particularly suitable neutral thickeners are, for example, cellulose derivatives such as hydroxypropylmethyl cellulose (HMPC), hydroxypropyl cellulose (HPC) or hydroxyethyl cellulose (HEC).

- HPC hydroxypropyl cellulose

- alkali or alkaline earth metal salts and in particular alkali metal salts expediently in the form of alkali metal chlorides, are particularly preferred.
- Sodium chloride is very particularly preferred as the pharmaceutically acceptable salt.
- the proportion of pharmaceutically acceptable salts to be included should expediently be in a range that is well tolerated by the skin, but on the other hand not too high as possible so that competition between the salts and the active ingredient is limited to a tolerable level.
- the salt is preferably present in a concentration of at least 75 mmol, more preferably at least 100 mmol and even more preferably at least 130 mmol.
- the iontophoretic composition according to the invention should, if possible, contain no more than 500 mmol, preferably no more than 300 mmol and even more preferably no more than 200 mmol of pharmaceutically acceptable salt.
- a further class of suitable thickeners are cationic thickeners, such as in particular those which (under the conditions under which they are used) have protonated amino groups. Since the positive charges are localized on the amino groups that are immobilized in the composition due to the size of the thickener molecules or have only a reduced mobility, transport of these cationic thickeners to the skin or to the counter electrode is largely prevented when the composition is used in an iontophoretic administration process. A decrease in ionic strength can thus be prevented and the iontophoretic process can be sustained for longer periods of time, while efficient transdermal absorption is ensured.
- Particularly suitable cationic thickeners are (meth) acrylate copolymers with amino groups, which can be primary, secondary and tertiary amino groups.
- the term (meth) acrylate copolymers denotes copolymers which are built up from methacrylate monomers, acrylate monomers and mixtures of acrylate and methacrylate monomers.

- the alkylated copolymers can also include hydroxylated alkyl groups, preferably C1 to C12 hydroxyalkyl groups such as hydroxymethyl, hydroxyethyl or hydroxypropyl.
- the "dimethylaminoethyl" unit is preferred as a constituent of the cationic thickener; such a group is present, for example, in dimethylaminoethyl methacrylate.
- Very particularly preferred thickeners are (meth) acrylate copolymers containing amine groups in the form of butylated and / or methylated methacrylate (s) and dimethylaminoethyl methacrylate.
- These preferred copolymers include the "basic butylated methacrylate copolymer” described in Pharmacopoea Europaea (Ph. Eur.), The “aminomethacrylate copolymer” described in USP / NF and the “aminoalkyl methacrylate copolymer E” described in "Japanese Pharmaceutical Excipients”.
