Přitom má býT terapeuticky účinná sloučenina přítomna vždy v koncentraci od asi 0,5 do 90 % hmotnostních, rztaženo na celkovou směs, tj. v množství, která jsou postačující к tomu, aby se dosáhlo uvedenénn rozsahu dávek.The new active substances can be converted in a known manner into conventional preparations such as tablets, dragees, pellet granules, aerosols, syrups, emulsions, suspensions and solutions, using inert, non-toxic, pharmaceutically acceptable carriers or solvents. The therapeutically active compound is always present in a concentration of from about 0.5 to 90% by weight, based on the total mixture, i.e. in amounts which are sufficient to achieve the stated dosage range.
Přípravky se yyríaějí například smísením účinných látek s rozpouštědly nebo/a nosnými láskami, popřípadě zi použití emulgátorů nebo/a dispergátorů, přičemž v případě použití vody jako ředidla se тэтой používat popřípadě organická rozpouštědla jakožto pomocná rozpouštědla.The formulations are prepared, for example, by mixing the active compounds with solvents and / or carrier substances, optionally using emulsifiers and / or dispersants, and optionally using organic solvents as co-solvents when water is used as the diluent.
Jako pomocné látky lze uvést například: vodu, netoxická organická rozpouštědla, jako parafinické uhlovodíky Cnapříklad ropné frakce), rostlinné oleje (například směs podzemnicovébo oleje a sezamovúio oleje), alkoholy (například ethylalkohol, glycerol), nosné látky, jako například příradní kamenné moučky (například kaoliny, aluminy, mastek, křídu), syntetické kamenné moučcy (jako například vysoce disperzní kyselinu křemičitou, křemičitany)» cukry (například třtinový cukr, mléčný cukr a hroznový cukr), emulgátory (například polyoxyethylenestery mastných kyselin, polyoxyethylenestery mastných alkoholů, alkylsulfonáty, arylsulíonáty), detergenty (například lignin, sulfitové odpadní louhy, methylcelulosu, škroby a polyvinylpyrrolidon) a látky kluzné (například hořečnatou sůl kyseliny stearové, mastek, stearovou kyselinu a natriumlaurylsulfát).Excipients which may be mentioned are, for example: water, non-toxic organic solvents such as paraffinic hydrocarbons (eg petroleum fractions), vegetable oils (for example a mixture of peanut oil and sesame oil), alcohols (for example ethyl alcohol, glycerol); e.g., kaolins, alumina, talc, chalk), synthetic stone meal (such as highly disperse silicic acid, silicates) »sugars (e.g., cane sugar, milk sugar, and grape sugar), emulsifiers (e.g. polyoxyethylene fatty acid esters, fatty alcohol polyoxyethylene esters, alkylsulfonates, arylsulonates), detergents (e.g., lignin, sulphite waste liquors, methylcellulose, starches and polyvinylpyrrolidone) and glidants (e.g., magnesium stearate, talc, stearic acid and sodium lauryl sulfate).
Aplikace se provádí obvyklým způsobem, výhodně perorálně nebo parenterálně, zejména perlinguálně nebo intravenosně. V případě orální aplikace mohou tablety obsahovat samozřejmě kromě uvedených nosných látek také přísady, jako sodnou sůl kyseliny citrónové, uhličitan vápenatý a dikalciumfosfát společně s různými přísadami, jako jsou škroby, výhodně bramborový škrob, želatina apod. Dále mohou obsahovat rovněž lubrikátory, jako hořečnatou sůl kyseliny stearové, natriumlaurylsulfát a mastek, které se používají jako pomocné látky při tabletování. V případě vodných suspenzí se mohou к účinným látkám pri- dávat kromě shora uvedených pomocných látek také různé látky zlepšující chuť nebo barviva.Administration is carried out in a conventional manner, preferably orally or parenterally, in particular perlingually or intravenously. In the case of oral administration, the tablets may of course also contain, in addition to the aforementioned carriers, additives such as sodium citric acid, calcium carbonate and dicalcium phosphate together with various additives such as starches, preferably potato starch, gelatin and the like. stearic acid, sodium lauryl sulfate and talc, which are used as tableting aids. In the case of aqueous suspensions, in addition to the abovementioned excipients, various flavor enhancers or colorants may be added to the active ingredients.
V případě parenterální aplikace se mohou používat roztoky účinných látek za použití vhodných kapalných masných látek.For parenteral administration, solutions of the active compounds using suitable liquid meat substances may be used.
Obecně se ukázalo výhodným používat při intravenosní aplikaci množství od asi 0,001 do 1 mgAg, výhodně od asi 0,01 do 0,5 mg/kg tělesné hmotnosti, aby se dosáhlo účinných výsledků. Při perorální aplikaci činí dávka od asi 0,01 do 20 mg/kg, výhodně od 0,1 rto 10 mg/kg tělesné hmotnosti.In general, it has proven advantageous to use an amount of from about 0.001 to 1 mgAg, preferably from about 0.01 to 0.5 mg / kg body weight, for intravenous administration, in order to achieve effective results. For oral administration, the dose is from about 0.01 to 20 mg / kg, preferably from 0.1 to 10 mg / kg body weight.
Přesto může být v některých případech popřípadě nutné odklonit se od uvedených množství a to v závislosti na tělesné hmotnosti, popřípadě na způsobu aplikace, na individuálním chování vůči medikamentu, na způsobu v jakém je podáván a na době, popřípadě intervalu, ke kterému se aplikace provádí. Tak může být v některých případech dostačující, použije-li se menšího množství než to, které je uvedeno shora jako minimální, zatímco v jiných případech se musí shora uvedená horní mez překročit. V případě aplikace větších množství lze doporučit rozdělit toto množství do několika jednotlivých dávek aplikovaných během dne.However, in some cases, it may be necessary to deviate from the indicated amounts, depending on body weight, the mode of administration, the individual behavior of the medicament, the manner in which it is administered, and the time or interval at which it is administered. . Thus, in some cases it may be sufficient to use less than the minimum listed above, while in other cases the above upper limit must be exceeded. In the case of administration of larger amounts, it is advisable to divide this into several individual doses administered during the day.
