Descrizione Description
Titolo: Realizzazione di un dispositivo di segnalazione dermatologico simile ad un patch test per l'identificazione di reazione allergica di medicamenti, preventiva alla somministrazione al paziente. Title: Creation of a dermatological signaling device similar to a patch test for the identification of allergic reactions to medicines, prior to administration to the patient.
Ambito dell'invenzione Scope of the invention
La presente invenzione si riferisce alla creazione di un dispositivo di segnalazione dermatologico simile ad un patch test personalizzato in grado di identificare una eventuale reazione allergica ai farmaci , che dovranno essere somministrati come terapia oftalmologica e o dermatologica, valutando in maniera preventiva le eventuali reazioni avverse da parte del paziente. The present invention refers to the creation of a dermatological signaling device similar to a personalized patch test capable of identifying a possible allergic reaction to drugs, which will have to be administered as ophthalmological or dermatological therapy, evaluating in advance any adverse reactions from the of the patient.
Stato della tecnica nota State of the prior art
Il Patch test ? solitamente eseguito per verificare se una particolare sostanza provochi una reazione allergica cutanea (dermatite da contatto); ? un esame indolore che si effettua tramite l'applicazione, sulla pelle del dorso, composti da cellette di plastica o alluminio adese al supporto di cerotti (patch) contenenti gli allergeni da valutare. Questi vengono lasciati sulla cute per 48-72 ore, durante le quali bisogna evitare di bagnarsi e, possibilmente, limitare la sudorazione evitando attivit? fisica e lavori pesanti per far s? che i cerotti stessi non si stacchino dalla pelle. Trascorse 48 ore, il medico procede ad una prima lettura per verificare l'eventuale presenza di reazioni cutanee (eritema, edema, papule o vescicole). Dopo 72 ore viene eseguita la lettura definitiva. Patch test ? un esame che saggia le reazioni di sensibilit? mediate da cellule (e non da anticorpi) che necessitano di almeno due giorni per realizzarsi. Il Patch test ? utile soprattutto per accertare le dermatiti da contatto e, per quanto riguarda alcuni aspetti delle allergie alimentari, per verificare la presenza di allergia al nichel e agli additivi alimentari contenuti nei cibi preconfezionati (ad es. marmellate, succhi di frutta, conserve, prodotti). Purtroppo i patch non possono essere utilizzati per le valutazioni dirette delle allergie ai farmaci. Patch testing? usually done to check if a particular substance causes an allergic skin reaction (contact dermatitis); ? a painless examination which is carried out through the application, on the skin of the back, composed of plastic or aluminum cells adhered to the support of plasters (patches) containing the allergens to be evaluated. These are left on the skin for 48-72 hours, during which it is necessary to avoid getting wet and, possibly, limit sweating by avoiding active activities. physics and hard work to make s? that the patches themselves do not detach from the skin. After 48 hours, the doctor carries out an initial reading to check for any skin reactions (erythema, oedema, papules or vesicles). After 72 hours the final reading is performed. Patch testing ? an examination that tests the reactions of sensitivity? mediated by cells (and not by antibodies) that need at least two days to develop. Patch testing? especially useful for ascertaining contact dermatitis and, as regards some aspects of food allergies, for verifying the presence of an allergy to nickel and food additives contained in pre-packaged foods (e.g. jams, fruit juices, preserves, products). Unfortunately the patches cannot be used for direct assessments of drug allergies.
Il nostro dispositivo offre la possibilit? di identificare una eventuale reazione allergica ai colliri che vengono testati, cosa che attualmente non ? possibile valutare in maniera preventiva se non dopo la somministrazione diretta del medicamento da parte del paziente. La caratteristica opzionale ? che il prodotto, pu? essere utilizzato in numerosi altri campi della medicina, come ad esempio la dermatologia ma non solo, per prodotti prettamente ad uso curativo. Our device offers the possibility? to identify a possible allergic reaction to eye drops that are tested, which currently is not? possible to evaluate in a preventive manner only after the direct administration of the drug by the patient. The optional feature ? that the product, pu? be used in numerous other fields of medicine, such as dermatology but not only, for products purely for curative use.
Sintesi dell'invenzione Summary of the invention
Le sostanze per uso oftalmico, colliri, geli, pomate cosi come qualsiasi soluzione destinata alla superficie corneale e per uso intraoculare, necessitano di una valutazione sulla tollerabilit?. Al fine di migliorare e ottimizzare l'affidabilit? della risposta terapeutica si ? ideato ed allestito un presidio che ha la possibilit? di far gestire allo stesso medico la scelta del medicamento da usare pi? adatto e che non causino reazioni di natura allergica al paziente. ? infatti noto anche dai dati di letteratura delle numerose reazioni a principi attivi/eccipienti contenuti in colliri, pomate o geli, in particolar modo a medicamenti che vengono somministrati nello specifico per la terapia antiglaucomatosa, antibiotica e nell'utilizzo di lacrime artificiali. Il dispositivo ? formato da una pellicola sottile con un dischetto forato che pu? contenere il gel (Carbomer 341) che viene preparato a parte e successivamente miscelato con il prodotto da esaminare e quindi posto sul dischetto forato. Per il nostro scopo sono stati preparati gel a differente concentrazione di Carbomer 341, dallo 0.3 allo 0.8% e neutralizzati con NaOH. Il gel che ha dato le migliori performance in termini di viscosit?, ? stato quello allo 0.8%, una volta miscelato con i differenti colliri e oppure farmaci da testare in un rapporto di 1:1. Substances for ophthalmic use, eye drops, gels, ointments as well as any solution intended for the corneal surface and for intraocular use, require an assessment of tolerability. In order to improve and optimize the reliability? of the therapeutic response yes? designed and set up a garrison that has the possibility? to have the same doctor manage the choice of medicine to use more? suitable and which do not cause allergic reactions to the patient. ? in fact it is also known from the literature data of the numerous reactions to active ingredients/excipients contained in eye drops, ointments or gels, especially to drugs that are administered specifically for anti-glaucomatous therapy, antibiotics and in the use of artificial tears. The device ? formed by a thin film with a perforated disk that pu? contain the gel (Carbomer 341) which is prepared separately and subsequently mixed with the product to be examined and then placed on the perforated disk. For our purpose, gels were prepared with different concentrations of Carbomer 341, from 0.3 to 0.8% and neutralized with NaOH. The gel that gave the best performance in terms of viscosity? was the one at 0.8%, once mixed with the different eye drops and/or drugs to be tested in a ratio of 1:1.
Esempi di utilizzo industriale: Examples of industrial use:
Il presidio ? stato realizzato mediante la preparazione estemporanea di varie tipologie di gels di natura sintetica e naturale. Il gel che maggiormente si ? mostrato compatibile con numerosi colliri oftalmici ? stato quello a base di Carbomer con concentrazione tra 0.3% e 0.8%. Questo nome sta a identificare una famiglia di omopolimeri reticolati ad alto peso molecolare dell'acido acrilico. Essi si presentano come polvere bianca disperdibile in acqua, dove le catene del polimero rimangono raggomitolate e devono essere neutralizzate con una base (a pH superiore a 5) in modo tale da farle distendere. I carbomer danno gels trasparenti e sono utilizzati in concentrazioni inferiori all' 1%. Le basi utilizzate come agenti neutralizzanti possono essere sia di natura inorganica (NaOH KOH, ecc) che composti organici (es. trietanolamina). Ogni prodotto (circa 10?L) viene saggiato su almeno 20 volontari. Ad ogni volontario possono essere applicati non pi? di 10 campioni. I campioni sono deposti in Finn Chambers<? >on Scanpor<? >di alluminio (SmartPractice<? >3400 E. The garrison? was achieved through the extemporaneous preparation of various types of synthetic and natural gels. The gel that most? shown compatible with numerous eye drops ? was the one based on Carbomer with a concentration between 0.3% and 0.8%. This name identifies a family of high molecular weight cross-linked homopolymers of acrylic acid. They appear as a white powder dispersible in water, where the polymer chains remain curled up and must be neutralized with a base (with a pH higher than 5) in order to make them relax. Carbomers give transparent gels and are used in concentrations of less than 1%. The bases used as neutralizing agents can be both of an inorganic nature (NaOH KOH, etc.) and organic compounds (e.g. triethanolamine). Each product (about 10?L) is tested on at least 20 volunteers. No more can be applied to each volunteer. of 10 samples. Samples are deposited in Finn Chambers<? >on scanpor<? >aluminium (SmartPractice<? >3400 E.
