Description

Ovaj izum odnosi se na jednu novu kombinaciju aktivnih tvari za liječenje poremećaja ekstrapiramidnih motoričkih sustava. This invention relates to a new combination of active substances for the treatment of extrapyramidal motor system disorders.

Esupron je ester etansulfonske kiseline i 7-hidroksi-3,4-dimetilkumarina: Esupron is an ester of ethanesulfonic acid and 7-hydroxy-3,4-dimethylcoumarin:

Ova tvar poznata je kao aktivna tvar za farmakoterapiju psihičkih poremećaja, osobito kao antidepresiv (EP-PS 111 746). This substance is known as an active substance for the pharmacotherapy of mental disorders, especially as an antidepressant (EP-PS 111 746).

Levodopa je odavna poznata tvar (Merck Index, 11. Auflage, Nr. 5344), koja se upotrebljava kao sredstvo protiv Parkinsonove bolesti: Levodopa is a long-known substance (Merck Index, 11. Auflage, Nr. 5344), which is used as a means against Parkinson's disease:

Sada je pronađeno da se kombinacijom obaju tvari može postići učinak koji se ne može objasniti zbrajanjem pojedinačnih učinaka. It has now been found that the combination of both substances can produce an effect that cannot be explained by the sum of the individual effects.

Predmet izuma su lijekovi koji sadrže Esupron i Levodopu. The subject of the invention are medicines containing Esupron and Levodopa.

Lijekovi mogu biti pripremljeni kao kombinirani pripremci za istovremenu primjenu u nepromjenjivoj kombinaciji ili odvojeno za istovremenu ili vremenski postupnu primjenu. Medicines can be prepared as combined preparations for simultaneous administration in an unchanging combination or separately for simultaneous or time-gradual administration.

Kombinacije su vrlo prikladne za liječenje poremećaja ekstrapiramidnog motoričkog sustava, osobito Parkinsonove bolesti. Combinations are very suitable for the treatment of disorders of the extrapyramidal motor system, especially Parkinson's disease.

Esupron i Levodopa daju se u kombinaciji i količinama koje su ispod dolnje granice doziranja obaju tvari kod njihovih pojedinačnih aplikacija. Dnevna doza Esuprona u pravilu je od 100 do 200 mg po pacijentu i daje se jednokratno. Dnevna doza Levodope iznosi u pravilu 25 do 200 mg po pacijentu. Ona se može dati zajedno s Esupronom ili također i s vremenskim razmakom. Dnevna doza Levodope može se također podijeliti i na 2 do 3 pojedinačna davanja tijekom jednog dana. Esupron and Levodopa are given in combination and in amounts that are below the lower dosage limit of both substances in their individual applications. As a rule, the daily dose of Esupron is from 100 to 200 mg per patient and is given once. The daily dose of Levodopa is usually 25 to 200 mg per patient. It can be given together with Esupron or also with a time gap. The daily dose of Levodopa can also be divided into 2 to 3 individual doses during one day.

Kombinacija se može davati na uobičajen način, npr. oralno ili intravenozno. The combination can be administered in a conventional manner, eg orally or intravenously.

Aktivne tvari mogu se primjenjivati u uobičajenim galenskim aplikacijskim oblicima kao što su tablete, kapsule, prašak, granule, dražeje ili otopine. Oni se pripremaju na uobičajen način. Pri tome aktivne tvari mogu se preraditi s uobičajenim galenskim pomoćnim sredstvima (uglavnom nosiocima i sredstvima za razređenje) kao što su talk, gumirabika, saharoza, laktoza, žitni ili kukuruzni škrob, krumpirovo brašno, magnezijev stearat, alginati, tragant guma, karagenati, polivinil alkohol, polivinil pirolidon, vodeni ili nevodeni nosioci, sredstva za kvašenje, sredstva za dispergiranje, emulgatori i/ili konzervansi (usporediti H. Sucker et. al., Pharmazeutische Technologie, Thieme-Verlag, Stuttgart 1978). Tako dobiveni pripremci uobičajeno sadrže aktivnu tvar u količini od 10 do 93% težinski. The active substances can be used in the usual galenic application forms such as tablets, capsules, powder, granules, dragees or solutions. They are prepared in the usual way. In this case, the active substances can be processed with the usual galenic aids (mainly carriers and diluents) such as talc, gum arabic, sucrose, lactose, wheat or corn starch, potato flour, magnesium stearate, alginates, gum tragacanth, carrageenates, polyvinyl alcohol, polyvinyl pyrrolidone, aqueous or non-aqueous carriers, wetting agents, dispersing agents, emulsifiers and/or preservatives (compare H. Sucker et. al., Pharmazeutische Technologie, Thieme-Verlag, Stuttgart 1978). The preparations thus obtained usually contain an active substance in an amount of 10 to 93% by weight.

Također je moguće pojedinačne sastojke kombinacije preraditi u aplikacijske oblike i te onda pakirati zajedno, npr. protiskivanjem. It is also possible to process the individual ingredients of the combination into application forms and then package them together, for example by pressing.

Terapeutsko i profilaktičko djelovanje kombinacije kod poremećaja ekstrapiramidnog motoričkog sustava dokazano je slijedećim pokusima: The therapeutic and prophylactic action of the combination in disorders of the extrapyramidal motor system was proven by the following experiments:

Omamljenim štakorima (mužjaci, 180 - 200 g) dat je unilateralno injekcijom 6-OH-dopamin (8 μg u 4 μl u 4 minute) u supstantia nigra. Anesthetized rats (males, 180 - 200 g) were given a unilateral injection of 6-OH-dopamine (8 μg in 4 μl in 4 minutes) into the substantia nigra.

Kod tako oštećenih životinja postsinaptička dopaminergična stimulacija, npr. pomoću apomorfina ili L-dopa, izaziva kontralateralno okretanje (Brain Research 24, 485 (1970). In such damaged animals, postsynaptic dopaminergic stimulation, eg by apomorphine or L-dopa, induces contralateral turning (Brain Research 24, 485 (1970).

Frekvencija okretanja je mjera za veličinu stimulacije. 10 dana nakon operacije ispitane su životinje dva do tri puta s 0,5 mg/kg tj.tež. apomorfina. Životinje koje su reagirale sa 70 ili više okretaja u 15 minuta bile su podvrgnute ispitivanju tvari. The turning frequency is a measure of the magnitude of the stimulation. 10 days after surgery, the animals were tested two to three times with 0.5 mg/kg, i.e. weight. apomorphine. Animals that responded with 70 or more revolutions in 15 minutes were subjected to the test substance.

Jednostrane aplikacije 6-OH-dopamina u supstantia nigra na štakorima dovodi do degeneracije dopaminergičkih neurona koji se tamo nalaze i do njihove projekcije u striatum. Te promjene odgovaraju patološkim anatomskim nalazima kako oni izgledaju kod Parkinsonove bolesti muškaraca. Na taj način dobije se dakle životinjski model za Parkinsonovu bolest. Samo jednostrano oštećenje u životinjskom modelu dovodi do asimetrije pokretanja (okretanja), koje omogućuje kvantificiranje oštećenja odnosno djelovanja tvari. Unilateral application of 6-OH-dopamine in the substantia nigra of rats leads to the degeneration of dopaminergic neurons located there and to their projection into the striatum. These changes correspond to pathological anatomical findings as they appear in Parkinson's disease in men. In this way, an animal model for Parkinson's disease is obtained. Only one-sided damage in the animal model leads to an asymmetry of starting (turning), which enables the quantification of the damage or the action of the substance.

L-DOPA u tom modelu u dozama od približno 200 do 300 mg/kg ip izaziva kontralateralno okretanje, što se može uzeti kao ekvivalent klinički poznatog djelovanja L-DOPA kod Parkinsonove bolesti. Doza od 21,5 mg/kg nedjelotvorna je (vidi tablicu). L-DOPA in this model at doses of approximately 200 to 300 mg/kg ip induces contralateral turning, which can be taken as equivalent to the clinically known effect of L-DOPA in Parkinson's disease. A dose of 21.5 mg/kg is ineffective (see table).

Rezultati the results

[image] [image]

Istovremenim davanjem Esuprona uspjeva se pojačati učinak L-DOPA. 2,15 i 4,64 mg/kg p.o. Esuprona (doze koje su, date same, također neučinkovite) u kombinaciji s L-DOPA izazivaju izrazita okretanja. Ovaj porast statistički je signifikantan. The simultaneous administration of Esupron succeeds in enhancing the effect of L-DOPA. 2.15 and 4.64 mg/kg p.o. Esuprone (doses which, given alone, are also ineffective) in combination with L-DOPA cause pronounced turns. This increase is statistically significant.
