Definitions
- the invention relates to a combination preparation in the sense of a "kit-of-parts" for the oral administration of antibiotics as an aqueous suspension containing a coated active ingredient and a syrup base.
- Filming, coating or coating active ingredient particles for example active ingredients which are in the form of crystals, agglomerates, granules, pellets or microtablets, is a common method in pharmaceutical technology to improve the stability of the active ingredient in an aqueous environment.
- the choice of coating agent is adapted to the therapeutic task.
- Coating with a high permeability polymer e.g. B .magensaftlöslichem Dimethylaminoethylmethacry- lat methacrylate copolymer of the type Eudragit ® E (Röhm GmbH Chemical Factory), and a suitable layer thickness, allows drug release in the acidic environment of gastric juice.
- the rapid release of the active substance is important if infectious conditions are to be treated within a short time immediately after their appearance and rapid onset of action with higher doses is desired.
- a coating with a lower permeability for example acrylic ester-methacrylic acid ester copolymer of the EUDRAGIT ® NE type, and possibly a greater layer thickness, the release of active ingredient in the stomach can be delayed with a corresponding prolongation of the duration of action. This effect is desirable with a longer therapy duration.
- Coated active ingredient particles are also only stable for a limited time in aqueous suspension.
- the undesired diffusion of the active ingredient into the suspension liquid takes place immediately after the suspension has been prepared. This results in the hydrolytic decomposition of the active ingredient and the significantly increasing deterioration in taste during the period of use of the suspension.
- the object of the present invention is to produce pharmaceutical suspensions (dry juices) with acceptable taste properties and sufficient stability for orally administrable antibiotics.
- the invention relates to a combination preparation for the oral administration of antibiotics as an aqueous suspension containing
- active ingredient component a) consists of coated active ingredient particles which are combined with component b), the suspending agent, before use.
- the two components are contained in two separate containers, which are packaged in a common package in the sense of a "kit of parts".
- the contents of the two containers are combined in a suitable container immediately before use.
- the two separate containers can be designed so that a single dose can be found in each case.
- the contents of the two containers can be combined in a storage vessel from which the measured amount of liquid can be removed until the end of the therapy.
- the storage container can be one of the two containers.
- the suspension produced in this way is characterized by favorable taste and stability properties. After the suspension has been prepared, the pleasant taste of the liquid and the effectiveness of the active ingredient are retained until the end of therapy.
- An oral antibiotic is administered as a single active ingredient or as a combination of active ingredients.
- Suitable active substances are selected from the group of penicillins, cephalosporins, quinolones, aminoglycosides and macrolides and can be combined with another active substance from the substance groups mentioned.
- the penicillins or cephalosporins can be combined with a ⁇ -lactamase inhibitor, for example clavulanic acid or sulbactam or tazobactam.
- a ⁇ -lactamase inhibitor for example clavulanic acid or sulbactam or tazobactam.
- the active ingredient component can be made of amoxicillin and clavulanic acid (Augmentan ® ) or. Ampicillin and Sulbactam (Unacid ® ) or Piperacillin and Tazobactam (Tazobac ® ) exist.
- penicillins such as amoxicillin, ampicillin, bacampicillin, nacillin-Na, propicillin-K, phenoxymethylpenicillin-K, flucloxacillin, dicloxacillin, oxacillin, or pivampicil-lin.

- the active ingredient component can also be selected from the group of aminoglycosides. Examples of these are neomycin sulfate or paromomycin.
- Macrolides such as azithromycin, clarithromycin, roxithromycin, josamycin or spiramycin I / II / III can also be used as active ingredient.
- rifampicin such as quinolones / nalixidic acid derivatives (gyrase inhibitors), such as e.g. Ciprofloxacin, Norfloxacin, Cinoxacin, Lomefloxacin, Moxifloxacin, Ofloxacin, Fleroxacin, Enoxacin, Perfloxacin, Trovafloxacin, Geprafloxacin, Sparfloxacin, Tusofloxacin, Enrofloxacin or Pipemidklare.
- quinolones / nalixidic acid derivatives such as e.g. Ciprofloxacin, Norfloxacin, Cinoxacin, Lomefloxacin, Moxifloxacin, Ofloxacin, Fleroxacin, Enoxacin, Perfloxacin, Trovafloxacin, Geprafloxacin, Sparfloxacin, Tusofloxacin, Enrofloxacin or Pipemidklare.
- clindamycin or lincomycin can also be used as an active ingredient in the combination preparation according to the invention.
- the active substances mentioned which have a salt-forming group, can, if not already stated, be present as pharmaceutically acceptable salts, for example alkali metal salts (sodium or potassium salts), alkaline earth metal salts (calcium or gastric salts), plasticites, starates, propionates, Choline salts, citrates, embonates, mesila te, sulfates or hydrochloride.
- the active ingredients can additionally contain half to ten moles of water of crystallization.
- the active substances mentioned, or their combinations are present in the dosages prescribed for oral administration.
- a suitable permeable, gastric juice-soluble coating agent consists of a film-like material which is permeable to acidic, aqueous systems, such as the contents of the stomach, and is swellable and / or soluble in these liquids.
- Suitable are e.g. hydrophilic polyacrylates with an average molecular weight of approx. 1.0 x 10 to 1.0 x 10, consisting of acrylic acid polymers or acrylic acid-methacrylic acid copolymers.
- the acid groups of the acrylic acid and / or methacrylic acid monomers are partially or completely esterified by C ⁇ -C4-alkyl groups, especially by methyl and / or ethyl groups, whereby these ester groups can be replaced by hydrophilic groups, especially trimethylammoniumethyl or dimethylaminoethyl.
- EUDRAGIT ® Preferred polyacrylates are available under the registered trademark EUDRAGIT ® from Röhm Chemische Fabrik GmbH.
- EUDRAGIT ® commercial forms are particularly preferred for rapidly disintegrating film coatings, for example swellable, permeable types based on acrylic acid ester / methacrylic acid ester copolymer, in particular ethyl acrylate / methyl methacrylate ester copolymer, for example gastric juice-soluble types such as EUDRAGIT ® E.
- ethyl cellulose methyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, polyvinyl acetate, polyvinyl alcohol, copolymers of methacrylic acid and methacrylic acid esters (Eudragit ® S / L) aminomethacrylate copolymers (Eudragit ® RS / RL), and acrylic acid polymers of the Carbopol type (eg Carbopol ® 934).
