Abstract: Disclosed are soluble polyelectrolyte complexes of polymeric biguanidine antimicrobial, such as polyhexamethylene biguanide or polyaminopropyl biguanide, with glycosaminoglycans, such as hyaluronic acid, chondroitin or chondroitin sulphate and derivatives thereof, and their use as active ingredients of pharmaceutical compositions or medical devices.

Abstract: New soft capsules are described having within them a fill which contains thyroid hormones such as thyroxine T4 or triiodothyronine T3) and a high amylose-starch, optionally associated with vegetable hydrocolloids and/or glycerol. Compared to traditional capsules, these capsules have a strong and unexpected increase in the stability of T4 or T3 during storage.

Abstract: Disclosed are injectable dermo-aesthetic formulations comprising aqueous solutions of at least one unmodified high-molecular-weight linear hyaluronic acid or hyaluronate and at least one unmodified low-molecular-weight linear hyaluronic acid or hyaluronate or non-sulphated chondroitin.

Abstract: Disclosed are intra-articular compositions comprising at least one low-molecular-weight linear hyaluronic acid or hyaluronate and at least one high-molecular-weight linear hyaluronic acid or hyaluronate, said compositions being characterised by a dynamic viscosity ranging between 10 and 60 Pa*s (at 0.01 s-1), a crossover frequency ranging between 1 and 10 rad/s, and a value of the viscous and elastic moduli at the crossover frequency ranging between 20 and 110 Pa.

Abstract: Disclosed is a process for the preparation of hydrogels consisting of crosslinked glycosaminoglycans, which comprises: a) reacting at least one hybrid cooperative complex obtained by heating aqueous solutions of low- and high-molecular-weight glycosaminoglycans at 80-160° C. with a diepoxide as crosslinker in a ratio with the complex ranging between 0.1 and 1 equivalents, preferably between 0.2 and 0.4 equivalents, the concentration by weight of the complex in the solution ranging between 1% and 15%, preferably between 2% and 10%; b) purifying by dialysis, ultrafiltration and diafiltration.

Abstract: The present invention relates to compositions based on: (a) a glycosaminoglycan or mixtures thereof; (b) one or more tocopherols, tocotrienols and mixtures thereof; and (c) a selected stabilizer. The composition is a solution, with the agents not chemically bound with each other. The component (a) can be hyaluronic acid (HA) or a salt thereof; the component (b) can be a polyether clathrate a cyclodextrin, or a combination of a fatty acid with an emulsifier; the component (c) can be ?-tocopherols, ?-tocopherols, ?-tocopherols, ?-tocopherols; ?-tocotrienols, ?-tocotrienols, ?-tocotrienols, ?-tocotrienols. Preferably component (c) is vitamin E. The agents strongly cooperate to provide enhanced and more stable viscoelastic properties, resulting in a product with higher resistance to thermal treatments like e.g. heat-sterilization, autoclaving, etc. The present compositions, optionally loaded with pharmaceutically and/or cosmetically active agents, are advantageously used in medical or cosmetic methods.

Abstract: Disclosed are soft gelatin capsules comprising a gelatin shell, a plasticiser, water, and optionally a calcium salt and a filling containing a dispersed or solubilised medicament comprising gelatin with gelling power, hydrolysed gelatin, glycerol, water, pectin and gellan gum. The formulations according to the invention allow gradual release of the active ingredient, regardless of pH.

Abstract: Disclosed are pharmaceutical or nutraceutical compositions comprising the peptide having the sequence NMYLPPVPPP PVVPTF or extracts containing it, in admixture with suitable excipients.

Abstract: Disclosed are ophthalmic formulations which use complexes called L/H-HA, obtainable by subjecting at least two fractions of hyaluronic acids and/or other glycosaminoglycans with different molecular weights to an appropriate heat cycle.

Abstract: New soft gelatin capsules highly protected against the degradation of the active ingredient contained therein and highly resistant to hydration are described. The capsular wall is characterized by containing hydroxypropyl beta cyclodextrin in low quantity with respect to the weight of the wall and sub-stoichiometric with respect to that necessary for complexing the drug contained within the capsule. The new capsules are storage-stable, avoid the development of active ingredient by-products and maintain a high weight constancy, i.e. low hygroscopy.

Abstract: The invention relates to a process for decontaminating a biological material by partitioning and inactivation techniques. The process includes the formation of a three-layer liquid system (a-b-c), where the layers are placed one onto the other and are different from each other in density and/or miscibility properties. The upper layer (a) has an aqueous solution of the biological material to decontaminate; the lower layer (c) has the solution inactivating viruses, prions or bacteria; the intermediate layer (b), interposed between the upper and lower layers, separates and protects the biological material from the inactivating solution which has an organic solvent or a mixture of more such solvents, immiscible at least with the upper layer. Moreover, the invention provides specific indications about the density difference between the layers in order to preserve system stability and, at the same time, protect the efficiency of decontamination and the biological activity of the material undergoing decontamination.

Abstract: The present invention provides for a method of improving the release of non-steroidal anti-inflammatory drugs (NSAIDs) from a plaster or bandage comprising an adhesive layer with a pharmaceutically acceptable NSAID together with heparin or a heparinoid. The invention also provides for methods of reducing muscle hyperalgesia in subjects without spontaneous pain.

Abstract: The present invention concerns the preparation and the therapeutic use of aqueous solutions of Progesterone or Testosterone, complexed with hydroxypropyl-?-cyclodextrin (HP?CD) that are suitable for oral administration. The solutions are characterised by a specific molar ratio between HP?CD and the hormones such as to ensure high hormone plasma levels, following oral administration, thanks to the optimisation of their solubility, permeability, metabolic stability and ultimately, bioavailability. The formulation object of the present patent makes it possible to achieve effective plasma concentrations following oral administration of lower doses of hormone with respect to oral formulations currently on the market (e.g. Prometrium, Andriol) to the advantage of greater safety and compliance of the patients.
