DESCRIZIONE DESCRIPTION

annessa a domanda di brevetto per INVENZIONE INDUSTRIALE dal titolo: attached to a patent application for INDUSTRIAL INVENTION entitled:

PRODOTTO. METODO ED USO DI POLIACRILAM-MIDE COME VEICOLO PER SOSTANZE FARMACO-LOGICHE. PRODUCT. METHOD AND USE OF POLYACRILAM-MIDE AS A VEHICLE FOR DRUG-LOGIC SUBSTANCES.

il presente trovato concerne un prodotto, metodo ed uso di poliacrilammide in gel, solido o liquido (ovvero di polimeri dell’ acrilammide) come veicolo o carrier per sostanze farmaceutiche o parafarmaceuticbe o per un dispositivo farmaceutico per uso topico, preferenzialmente iniettivo. the present invention relates to a product, method and use of polyacrylamide in gel, solid or liquid (or acrylamide polymers) as a vehicle or carrier for pharmaceutical or para-pharmaceutical substances or for a pharmaceutical device for topical use, preferably injecting.

L’utilizzo di questo prodotto è attualmente noto nella ricostruzione, come riempitivo per endoprotesi od in campo estetico in generale: questo in virtù delle caratteristiclie di atossicità totale del prodotto stesso nei confronti del tessuto vivente, ovvero del fatto cbe lo stesso prodotto si presenta inerte sia dal punto di vista cbimico cbe fisico, non è tossico, non è cancerogeno, è stabile sia dal punto di vista cbimico cbe fisico, è facilmente iniettabile anche sottocute, è perfettamente modellabile una volta iniettato ed è di consistenza simile al tessuto cbe sostituisce od affianca. The use of this product is currently known in reconstruction, as a filler for endoprostheses or in the aesthetic field in general: this is due to the characteristics of total non-toxicity of the product itself towards living tissue, or the fact that the same product is inert both from the biological and physical point of view, it is not toxic, it is not carcinogenic, it is stable both from the biological and physical point of view, it is easily injectable even under the skin, it is perfectly moldable once injected and is of a consistency similar to the tissue that replaces or alongside.

il prodotto sopra indicato comprende poliacrilammide ed un quantitativo di acqua variatile in funzione delle esigenze dell’ applicazione, diciamo fino ad un massimo del 95-98% in peso di acqua. the product indicated above includes polyacrylamide and a quantity of water that varies according to the needs of the application, let's say up to a maximum of 95-98% by weight of water.

La richiedente ha sorprendentemente ritrovato come questo prodotto potesse fungere da veicolo per un prodotto od una sostanza farmaceutica che potesse disciogliersi o miscelarsi nell’acqua. In altre parole, all’acqua di composizione con il poliacrilammide viene aggiunta la sostanza desiderata (che può essere un vero e proprio farmaco od un disinfettante) nella percentuale che si riterrà la più opportuna, il prodotto risultante (poliacrilammide acqua sostanza) viene quindi iniettato nella zona da trattare ed ivi lasciato. La proprietà tipica del prodotto sarà di rilasciare il composto acqua farmaco in modo che lo stesso possa interagire con il tessuto circostante ed esercitare l’azione diretta funzione delle caratteristiche della sostanza rilasciante: ad esempio antitumorale, antihiotica, ecc. L’effetto sorprendente è dato dal fatto che il rilascio è controllabile in funzione dello stato di viscosità iniziale del prodotto, specie se in gel, fino a tempi estremamente variahili e quantificabili in settimane. L’effetto primario è dato dal fatto che, una volta rilasciato completamente il composto acqua sostanza attiva, il polimero rimanente risulterà compietamente inerte per l’organismo, il risultato positivo è altresì dato dal fatto che, modulando diversamente il rilascio della sostanza attiva, è possibile ottenere risultati con minore utilizzo del farmaco, minore tossicità ed uso esclusivamente topico. The Applicant has surprisingly found how this product could act as a vehicle for a pharmaceutical product or substance that could dissolve or mix in water. In other words, the desired substance (which can be a real drug or a disinfectant) is added to the water of composition with polyacrylamide in the percentage that will be considered most appropriate, the resulting product (polyacrylamide water substance) is then injected in the area to be treated and left there. The typical property of the product will be to release the drug water compound so that it can interact with the surrounding tissue and exert the direct action function of the characteristics of the releasing substance: for example, antitumor, antihiotic, etc. The surprising effect is given by the fact that the release is controllable according to the initial viscosity state of the product, especially if in gel, up to extremely variable times that can be quantified in weeks. The primary effect is given by the fact that, once the active substance water compound has been completely released, the remaining polymer will be completely inert for the organism, the positive result is also given by the fact that, by modulating the release of the active substance in a different way, it is It is possible to obtain results with less use of the drug, less toxicity and exclusively topical use.

il trovato così concepito è suscettibile di numerose modifiche e varianti, tutte rientranti nell'ambito del concetto inventivo. the invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
