Patent number: 6103269Abstract: The invention relates to accurately meterable shaped articles, for example granules or pellets, containing hydrophilic macromolecules, active compounds and optionally further pharmaceutically acceptable structure-forming substances and auxiliaries, the active compound being present in a matrix in dissolved, suspended or emulsified form, and a novel process for the production of these shaped articles, the process being particularly economically and ecologically acceptable, and use of the shaped articles as medicaments, in which the bioavailability, shelf life and tolerability is increased. Using the shaped articles or mixtures according to the invention, intermediates or final products for pharmacy, cosmetics, diagnosis, analysis or dietetics (healthcare) can additionally be advantageously prepared.Type: GrantFiled: March 1, 1999Date of Patent: August 15, 2000Assignee: Alfatec-Pharma GmbHInventors: Jens-Christian Wunderlich, Ursula Schick, Jurgen Werry, Jurgen Freidenreich

Patent number: 6066332Abstract: A medicament for immediately treating painful, inflammatory and/or febrile diseases contains as active substance ibuprofen as a racemate, as a racemic mixture with its enantiomers, as a pseudoracemate (mixtures of equal parts of S- and R-ibuprofen) or as a mixture of different parts of S- and R-ibuprofen in a range between pure S- and pure R-ibuprofen in the form of a pharmaceutically applicable nanosol and satisfies all requirements of an immediate-effect pharmaceutic form. It can in addition be combined with a slow-release medicament that contains as active substance ibuprofen as a racemic compound, as a pseudoracemate (mixtures of equal parts of S- and R-ibuprofen) or as a mixture of different parts of S- and R-ibuprofen in a range between pure S- and pure R-ibuprofen, in the form of a pharmaceutically applicable, gelatine-based nanosol.Type: GrantFiled: December 1, 1995Date of Patent: May 23, 2000Assignees: Alfatec-Pharma GmbH, PAZ Arzneimittelentwicklungsgesellschaft mbHInventors: Jens-Christian Wunderlich, Otto Schuster, Helmut Lukas, Ursula Schick

Patent number: 5932245Abstract: Nanosols and process for preparing the same allow colloidally dispersed solutions of scarcely water-soluble active substances to be stabilized with gelatin or its derivatives, by partly or fully setting the iso-ionic point (IIP, equivalent to a neutral charge) between the gelatin and the surface charged active substance particles. In order to neutralize the charge of the system composed of active substance particles and gelatin, the surface charge of the particles is compensated by a corresponding opposite charge of the gelatin molecules. For that purpose, a determined charge in relation to the isoelectric point (IEP) and the pH value of the solution is set on the gelatin molecules. By stabilizing in this way the practically monodispersed state thus generated, the Ostwald maturation of the colloidal particles of scarcely soluble active substance is strongly reduced.Type: GrantFiled: October 25, 1994Date of Patent: August 3, 1999Assignee: Alfatec Pharma GmbHInventors: Jens-Christian Wunderlich, Ursula Schick, Jurgen Werry, Jurgen Freidenreich

Patent number: 5902606Abstract: Sparingly water-soluble active compounds, for example medicinal substances, are converted into the dissolved (molecularly disperse) state by dissolving them in a hydrophilic peptide having a molecular weight above 100 D, for example gelatin. The solubility both during storage and during use of the formulation by the user or patient is thereby ensured, without organic solvents or solubilizing agents which cause undesirable side effects being required.Type: GrantFiled: March 17, 1995Date of Patent: May 11, 1999Assignee: Alfatec-Pharma GmbHInventors: Jens-Christian Wunderlich, Ursula Schick, Jurgen Werry, Jurgen Freidenreich

Patent number: 5614219Abstract: A peroral administration form for peptidic medicaments contains the peptidic medicament, in particular insulin, distributed in a gelatine or gelatine derivate matrix, besides usual pharmaceutical excipients and additives. By selecting an appropriate gelatine, the medicament is released in the small or large intestine, so that it is no longer enzymatically decomposed by peptidases.Type: GrantFiled: September 13, 1994Date of Patent: March 25, 1997Assignee: Alfatec-Pharma GmbHInventors: Jens-Christian Wunderlich, Ursula Schick, Jurgen Werry, Jurgen Freidenreich

Patent number: 5578307Abstract: Shaped articles containing plant extract(s), in particular pellets, are formed by dispersing the plant extract(s) in a matrix predominantly composed of a skeleton builder, i.e. collagen, gelatin, fractionated gelatin, a collagen hydrolysate, a gelatin derivative, plant protein or plant protein hydrolysate. They are storage-stable, and their pharmacological and cosmetic characteristics are essentially unaltered in comparison with the native extract. They are prepared by a simple process in which liquid plant extract(s) is(are) mixed or emulsified in a solution of the skeleton builder, or solid extracts are dissolved or suspended in a solution of the skeleton builder, the dispersion of skeleton builder and plant extract(s) is added dropwise to an intensely cold, inert, liquefied gas, preferably liquid nitrogen, thus shaping the pellets, and the shaped pellets are dried. The plant extract employed is preferably Aloe vera juice.Type: GrantFiled: October 18, 1994Date of Patent: November 26, 1996Assignee: Alfatec-Pharma GmbHInventors: Jens-Christian Wunderlich, Ursula Schick, Jurgen Werry, Jurgen Freidenreich

Patent number: 5560924Abstract: Immediate-effect medicaments containing a pharmacologically active 2-arylpropionic acid derivate as a pharmaceutically applicable nanosol have a considerably improved action start and bioavailability of the active substance. The 2-arylpropionic acid derivates, for example ibuprofen, flurbiprofen and ketoprofen, that are scarcely soluble in an aqueous medium, are present in a gelatine-stabilized nanosol in a form that allows these active substances to be quickly and completely resorbed already in the stomach. The disclosed colloidal disperse system composed of a 2-arylpropionic acid derivate is prepared by selecting a gelatine or gelatine derivate according to their isoelectric point (IEP), so that their IEP is adapted to the charge of the 2-arylpropionic acid derivate particles, leading to a neutral charge when the gelatine or its derivate is combined with the undissolved 2-arylpropionic acid derivate at a determined pH value.Type: GrantFiled: September 29, 1994Date of Patent: October 1, 1996Assignees: Alfatec-Pharma GmbH, PAZ Arzneimittelentwicklungsgesell schaft mbHInventors: Jens-Christian Wunderlich, Ursula Schick, Jurgen Werry, Jurgen Freidenreich, Helmut Lukas, Otto Schuster
