Complexes of deprotonated hyaluronic acid with 3d metal ions of the 4th period of the Periodic Table and compositions containing these complexes as active ingredients or carriers. A process for the preparation of the complexes and compositions (pharmaceutical and cosmetic compositions) containing these complexes as active ingredients are disclosed in which zinc or cobalt (II) hyaluronate is preferably used as active ingredient.

Compositions containing hyaluronic acid associates and a process for preparing same

This invention relates to a process for the production of optimally stable orally administrable solution forms of medicaments containing high-molecular polysaccharides, with controlled release of drugs having beta-blocking action, this process consisting of the reacting of 1 to 20 parts (w/w) of beta-blocking agent (oxprenolol, pindolol, sotalol, metoprolol, alprenolol, acebutolol, atenolol, bopindolol, practolol, nadolol or propranolol) in 100 parts of an aqueous solution with 0.001 to 10.0 parts of a polysaccharide polymer, advantageously with Xanthan Gum having beta-1,4-glucan chain, or dextran, or amylodextrin, or carboxymethylamylum. The reaction is allowed to take place in the course of 20 minutes at a pH adjusted no 2.0-4.5, with vigorous stirring at 80.degree. C. temperature. Following the usual method of the pharmaceutical practice, the system is then formulated by the addition of water to obtain a solution suitable for oral administration.

The present invention relates to a stabilized plant protecting agent suspension which can be characterized by containing 10 to 60% by weight of one or more active ingredients, 30 to 5% by weight of oily layer, 0 to 10% by weight of emulsifier, 10 to 20% by weight of conventionally used excipient and water needed to 100% by weight while by increasing solid concentration oil concentration decreases. The invention also provides a process for the preparation of a stabilized plant protecting agent suspension by adding oil and optionally an emulsifier and/or water containing layer to a suspension of a suitable particle size of the active ingredient and water soluble excipients, such as surfactants, optionally emulsifiers, dispersing agents, viscosity modifying agents, protective colloids and mixing together the suspension layer and the layer containing the oil with a stirrer of great shearing force and optionally adding to the obtained stabilized suspension further excipients, e.g. viscosity modifying agents, anti-foaming agent, protective colloid and dispersing agent.

Stabilized plant protecting carbofuran suspensions

The invention relates to carbofurane-containing plant protecting compositions. More particularly, the invention concerns insecticide compositions with improved plant growth accelerating properties, containing 1 to 50% by weight of 2,3-dihydro-2,3-dimethyl-7-benzofuranol methylcarbamate optionally along with usual amounts of additives conventionally used in the manufacture of plant protecting compositions, which comprises 50 to 99% by weight of a carrier granulate prepared by partial hydrolysis of vegetable waste matters, preferably corn-cob, corn-stalk, chopped wood or sawdust derived from broad leaved trees, rice hull, read or broaken reed, known per se.

Carbofuran-containing plant protecting compositions

The present invention relates to a solid oral pharmaceutical preparation with protracted release of the active ingredient consisting of discrete solid granules containing the active ingredient soluble in the stomach and auxiliary agents and of an equally solid external phase surrounding the said granules, whereby the granules forming the internal phase consist of granules prepared from a powder mixture which contains as active ingredient, or in addition to it a non-toxic metal compound, being capable of binding an acid, and being insoluble or but slightly soluble in neutral aqueous medium--particularly bismuth, aluminium or magnesium compound--and auxiliary materials prepared with an aqueous emulsion containing a hydrophobic component and hydrophylic emulsifiers, and the external phase contains a solid, dry, amphoteric gel forming substance in an amount of 1-50 percent w/w related to the total weight of the preparation in admixture with auxiliary agents. The preparation is produced by the wetting of the powder mixture containing the basic metal compound, auxiliary material and in given case additional active ingredient with the aqueous emulsion of the hydrophobic component prepared by applying the hydrophylic emulsifiers then by granulation and admixing the dried granules with the amphoteric gel forming substance, and pressing it into tablets, or filling into capsules.
