No. 4,472,305, preferably in doses between about 0.05 and 500 mg , in particular between 0.5 and 100 mg administered per dosage unit.
• the daily dosage is preferably between about 0.01 and 2 mg / kg body weight.
• the specific dose for each patient depends on a variety of factors, for example on the effectiveness of the particular compound used, on the age, body weight, general health, sex, on the diet, on the time and route of administration, on the rate of elimination, combination of drugs and severity the respective disease to which the therapy applies. Parenteral administration is preferred.
• customary work-up means: if necessary, water is added, if necessary, depending on the constitution of the end product, the pH is adjusted to between 2 and 10, extracted with ethyl acetate or dichloromethane, and the mixture is separated off, dries the organic phase over sodium sulfate, evaporates and purifies by chromatography on silica gel and / or by crystallization.
• Example A Injection glasses
• a solution of 100 g of an active ingredient of the formula I and 5 g of disodium hydrogenphosphate is adjusted to pH 6.5 in 3 l of double-distilled water with 2N hydrochloric acid, sterile filtered, filled into injection glasses, lyophilized under sterile conditions and sealed sterile. Each injection jar contains 5 mg of active ingredient.
• a mixture of 20 g of an active ingredient of the formula I is melted with 100 g of soy lecithin and 1400 g of cocoa butter, poured into molds and allowed to cool. Each suppository contains 20 mg of active ingredient.
• a solution of 1 g of an active ingredient is prepared of the formula I, 9.38 g of NaH 2 P0 4 • 2 H 2 0, 28.48 g Na 2 HP0 4 • 12 H 2 0 and 0.1 g of benzalkonium chloride in 940 ml of double distilled water. It is adjusted to pH 6.8, made up to 1 I and sterilized by irradiation. This solution can be used in the form of eye drops.
• Example D ointment
• 500 mg of an active ingredient of the formula I are mixed with 99.5 g of petroleum jelly under aseptic conditions.
• Example F coated tablets
• Example E tablets are pressed, which are then coated in a conventional manner with a coating of sucrose, potato starch, talc, tragacanth and colorant.
• Example G capsules
• each capsule contains 20 mg of the active ingredient.
• a solution of 1 kg of active ingredient of the formula I in 60 l of double-distilled water is sterile filtered, filled into ampoules, lyophilized under sterile conditions and sealed under sterile conditions. Each ampoule contains 10 mg of active ingredient.
