Definitions
- the invention relates to the use of pramipexole (2-amino-4,5,6,7-tetrahydro-6-n-propylamino-benzothiazole), its (+) or (-) enantiomer, its pharmacologically acceptable acid addition salts and hydrates and solvates for Manufacture of a medicinal product for the prevention and / or treatment of HIV encephalopathy.
- the 2-amino-6-n-propylamino-4.5 l of 6,7-tetrahydrobenzo-thiazole is a D2 / D3-dopamine receptor agonist which is also known under the name Pramipexol or its (+) - enantiomer under the Name SND 919 is known in the prior art.
- Pramipexole and processes for its production are known, for example, from EP-A-186 087 and US 4,886,812. Above all, the utility of pramipexole for the treatment of schizophrenia and in particular for the treatment of Parkinson's is known. In addition, the neuroprotective effect of pramipexole has been described in WO 009618395, among others.
- HIV infections are often associated with neurological dysfunctions, which are manifested, for example, in behavioral disorders, motor disorders and cognitive impairments (Czub et al., Acta neuropathol., 2001, 101; 85-91). HIV dementia should be mentioned in particular as a symptom of these functional disorders.
- HIV encephalopathy Treatment of HIV encephalopathy with classic Parkinson drugs, such as L-dopa or selegiline, has not proven to be effective. It is the object of the present invention to provide an active ingredient for the treatment of HIV encephalopathy, in particular for the treatment of HIV dementia.
- pramipexole is suitable for the prevention and / or treatment of HIV encephalopathy, in particular HIV dementia.
- the present invention therefore relates to the use of pramipexole and its pharmacologically acceptable acid addition salts, as well as hydrates and solvates, for Manufacture of a medicinal product for the prevention and / or treatment of HIV encephalopathy.
- pramipexole (-) enantiomer and its pharmacologically acceptable acid addition salts, as well as hydrates and solvates, for the manufacture of a medicament for the prevention and / or treatment of HIV encephalopathy.
- pramipexole for the manufacture of a medicament for the treatment of HIV dementia is particularly preferred.
- pramipexole for the manufacture of a medicament for the treatment of HIV-associated motor disorders is also particularly preferred.
- pramipexole for the manufacture of a medicament for the treatment of HIV-associated cognitive impairment is also particularly preferred.
- pramipexole for the production of a medicament for the treatment of HIV-associated behavior disorders is particularly preferred.
- Another object of the present invention is the use of pramipexole in combination with one or more active substances selected from the group consisting of nucleoside and non-nucleoside inhibitors of reverse transcriptase, HIV protease inhibitors and other HIV replication inhibitors, antiviral active substances in the context of a HAART (highly active antiretroviral therapy), AIDS vaccines, inhibitors of virus adhesion and virus uptake in mammalian cells, in particular CXCR4 and CCR5 chemokine receptor antagonists, combinations with several antiviral agents in the context of a hair and CXCR4 and CCR5 chemokine receptor are particularly preferred Antagonists, particularly preferred are CXCR4 and CCR5 chemokine receptor antagonists.
- active substances selected from the group consisting of nucleoside and non-nucleoside inhibitors of reverse transcriptase, HIV protease inhibitors and other HIV replication inhibitors, antiviral active substances in the context of a HAART (highly active antiretrovir
- the present invention relates to a pharmaceutical composition containing pramipexole in combination with one or more active substances selected from the group consisting of nucleoside and non-nucleoside inhibitors of reverse transcriptase, HIV protease inhibitors and other HIV replication inhibitors, antiviral active substances in the context of a HAART (highly active antiretroviral therapy), AIDS vaccines, inhibitors of virus adhesion and virus uptake in mammalian cells, in particular CXCR4 and CCR5 chemokine receptor antagonists, combinations with several antiviral active ingredients in the context of a hair and CXCR4 and CCR5 chemokine receptor antagonists are particularly preferred, and CXCR4 and CCR5 antagonists are particularly preferred
- pramipexole for the treatment of HIV-infected patients is preferred.
- pramipexole can be used as a racemate, in the form of its (+) - or in the form of its (-) - enantiomer.
- Pramipexol can also be used in the form of its pharmaceutically acceptable acid addition salts and, if appropriate, in the form of its hydrates and / or solvates.
- pharmaceutically acceptable acid addition salts are understood to be those salts which are selected from the salts of hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, methanesulfonic acid,
- indications can alternatively also be one Combination therapy of pramipexole with one or more pharmaceutically active compounds can be performed.
- Pramipexole is able to intercept various radicals and thereby render them harmless. Since free radicals play a role in the development of HIV encephalopathy, especially HIV dementia, the use of pramipexole in HIV dementia leads to a therapeutic effect.
- the Scavenge function of Pramipexol is among others supported by the following experimental data from experiments A (in vitro), B (in vivo) and C (in vitro):
- Mitochondria reduce 95% of the oxygen to water.
- As a (patho-) physiological side reaction up to 5% of the oxygen is incompletely reduced to the superoxide anion, which is normally reduced to water via hydrogen peroxide.
- Overproduction and / or reduced detoxification of superoxide anion and hydrogen peroxide leads to the generation of oxidative stress. This is significantly involved in neuronal cell death in a wide variety of neurodegenerative diseases.
- Isolated mitochondria produce succinate H 2 0 2 in the presence of the energy substrate, which derives from the dismutation of superoxide anion.
- the fluorogenic chromophore resorufin is formed in the presence of amplexRed TM and horse-radish peroxidase, which is measured and quantified in a kinetic test.
- the amount of H 2 0 2 formed by the mitochondria can be increased by adding the quinone analogue duroquinone. The test result is shown in Table 1.
- Pramipexole reduces the duroquinone-induced H 2 0 2 formation to approx. 50-60%. Since Pramipexole neither reacts with H 2 0 2 nor influences the detoxification of H 2 0 2 by the mitochondrial metabolism, Table 1 shows that the superoxide anion is detoxified by Pramipexole. This reduces the amount of the secondary product formed from 0 2 " , H 2 0 2 .
- Aconitase is a mitochondrial enzyme that catalyzes the conversion of citrate to isocitrate in the citrate cycle. In its active center it carries an iron-sulfur cluster [4Fe-4S], which is required for catalytic activity. This iron-sulfur cluster is specific to the radicals
- NO nitrogen monoxide
- Different NO donors can be used to generate NO in situ.
- the donors differ in their half-life, so they release different amounts of NO per unit of time at the same concentration.
- the NO generation was measured by triazole formation from diaminofluorescein and a NO donor. Different concentrations of pramipexole or (+) enantiomer were added to this system.
- IC-50 values are in the range from 13 ⁇ M -80 ⁇ M depending on the donor used and the one used
- Pramipexole and the (+) enantiomer thus act as NO-
- Pramipexole is naturally very dependent on the clinical picture.
- pramipexole can be used in doses of about 0.05 to 7.5 mg, preferably 0.1 to 5 mg, per day. These dosages are based on pramipexole in the form of its free base. Based on the preferred salt form of pramipexole dihydrochloride monohydrate, these correspond to Dosages mentioned above about 0.07 to 10.65 mg, preferably 0.14 to 7.1 mg pramipexole dihydrochloride monohydrate per day.
- 2nd week 1 tablet 3 times a day containing 0.18 mg pramipexole; Week 3 and following: 1/2 tablet 3 times a day - containing 0.7 mg pramipexole.
- pramipexole can be administered orally, transdermally, intrathecally, by inhalation or parenterally.
- Suitable forms of use are, for example, tablets, capsules, suppositories, solutions, juices, emulsions, dispersible powders or plasters.
- Corresponding tablets can be mixed, for example, by mixing the active ingredient (s) with known auxiliaries, for example inert diluents such as calcium carbonate, calcium phosphate or milk sugar, disintegrants such as corn starch or alginic acid, binders such as starch or gelatin, lubricants such as magnesium stearate or talc, and / or agents to achieve the depot effect, such as carboxymethyl cellulose, cellulose acetate phthalate, or polyvinyl acetate.
