The invention relates to a pharmaceutical oral capsule preparation filled with a substantially anhydrous mixture which is in solid or semi-solid form comprising: (a) a drug or a drug treated by a conventional manner, each of which is in solid form, and (b) a drug carrier which is a semi-solid mixture comprising a selected aqueous polymer and a selected liquid oil, the ratio of aqueous polymer to liquid oil by weight being 2:1 to 1:40.

Novel drug carrier and pharmaceutical preparation comprising the same

The present invention relates to soft capsules comprising (a) polymers prepared by polymerization of vinyl esters in the presence of polyethers (b) where appropriate structure-improving auxiliaries and (c) where appropriate other conventional constituents, the use and production thereof.

Soft capsules comprising polymers of vinyl esters and polyethers, the use and production thereof

The invention relates to the application of polymerizates which can be obtained by the polymerization of: a) at least one vinyl ester of aliphatic C1-C24 carboxylic acids in the presence of b) polyethers of general formula (I): R?1-(-O-(R2-O)?u-(R3-O)v-(R4-O)w-[-A-(R5-O)x-(R6-O)y-(R7-O)z-]S-R8)n in which the variables, independent of one another, have the meaning cited in the description. Said polymerizates are used as a coating agent, binding agent and/or as a film-forming auxiliary agent in pharmaceutical forms of administration.

Application of water-soluble or water-dispersible polymerizates which contain poly-ether and which are used as a coating agent, a binding agent and/or as a film-forming auxiliary agent in pharmaceutical forms of administration

A capsule is formed from a PVA composition by blow moulding. Such capsules can at last provide a viable alternative to gelatin for bio-degradeable capsule containing a pharmaceutical or consumable or other substance, for example a detergent. The capsules may contain solid or liquid substances. Blow moulding apparatus suitable for forming such capsules is also disclosed and claimed.

Method and apparatus for blowmolding capsules of polyvinylalcohol and blowmolded polyvinylalcohol capsules

The present invention relates to hard capsules comprising (A) polymers obtainable by free-radical polymerization of a) at least one vinyl ester in the presence of b) polyether-containing compounds and c) where appropriate one or more other copolymerizable monomers c) and subsequent at least partial hydrolysis of the ester functions in the original monomers a), with the proviso that in the absence of another copolymerizable monomer c) the polyether-containing compound b) must have a number average molecular weight ≦10,000, (B) where appropriate structure-improving auxiliaries and (C) other conventional shell constituents, the production and use thereof.
