Description

FORMULACIJE AEROSOLOV BREZ KLOROFLUOROOGLJIKOVFORMULATIONS OF AEROSOLS WITHOUT CHLOROFLUOROCARS

Predstavitev izumaPresentation of the invention

Predstavljeni izum je usmerjen k formulacijam aerosolov, ki so popolnoma brez klorofluoroogljikov (CFC). Bolj specifično, predstavljeni izum je usmerjen k formulacijam, ki so brez CFC in imajo posebno uporabnost v medicinskih sredstvih, posebej v inhalatorjih z odmerjeno dozo pod pritiskom (MDI).The present invention is directed to formulations which are completely chlorofluorocarbons (CFC) aerosols. More specifically, the present invention is directed to formulations that are CFC-free and have particular utility in medical devices, especially in metered dose inhalers (MDI).

Dokazano je, da so inhalatorji z odmerjeno dozo pod pritiskom učinkovita metoda za dajanje zdravil oralno in nazalno. Široko jih uporabljajo pri dajanju bronhodilatantnih in steroidnih spojin astmatikom in so lahko prav tako uporabni za dajanje drugih spojin, kot so pentamidin ter antiinflamatornih zdravil, ki niso bronhodilatatorji. Rapidno zvišanje aktivnosti spojin, ki jih dajemo na ta način, in odsotnost kakršnihkoli stranskih učinkov sta dala veliko število spojin, ki so formulirane za dajanje po tej poti. Tipično dajemo zdravilo pacientom s sistemom s pogonskim sredstvom (propellant), ki na splošno vsebuje enega ali več pogonskih sredstev, ki imajo ustrezni parni tlak in so primerni za oralno in nazalno dajanje. Najbolj zaželjeni sistemi pogonskih sredstev vsebujejo pogonsko sredstvo 11, pogonsko sredstvo 12, pogonsko sredstvo 114 ali pa njihovo mešanico. Pogosto reguliramo parni tlak sistema s pogonskim sredstvom z mešanjem tekočega ekscipienta (inertno polnilo) s pogonskim sredstvom.Dosing pressure inhalers have been shown to be an effective method of administering drugs orally and nasally. They are widely used in the administration of bronchodilator and steroid compounds to asthmatics and may also be useful for the administration of other compounds such as pentamidine and anti-inflammatory drugs other than bronchodilators. The rapid increase in the activity of the compounds administered in this manner and the absence of any side effects produced a large number of compounds formulated for administration by this route. Typically, the drug is administered to patients with a propellant system, which generally contains one or more propellants that have adequate vapor pressure and are suitable for oral and nasal administration. Most preferred propellant systems include propellant 11, propellant 12, propellant 114, or a mixture thereof. We often regulate the vapor pressure of the system with the propellant by mixing the liquid excipient (inert filler) with the propellant.

Vendar pa pogonska sredstva 11, 12 in 114 spadajo v razred spojin, ki so znane kot klorofluoroogljiki, ki so povezani z odvajanjem ozona iz atmosfere. Ugotovljeno je bilo, da ozon zadrži določene škodljive UV žarke in, da bo upadanje vsebnosti ozona v atmosferi povzročilo povečano pogostost kožnega raka. Da bi zmanjšali emisijo CFC iz aerosolov, so leta 1970 naredili določene korake. Uporabljali so druga pogonska sredstva, kot so ogljikovodiki, ali pa so proizvod dajali na drugačen način. Ker je uporaba CFC v medicinskih sredstvih relativno nizka, t.j. manj kot 1% celotne emisije, in zaradi koristnosti zdravju, ki je povezana z inhalatorji z odmerjeno dozo pod pritiskom, v tistem času niso omejili uporabe CFC pogonskih sredstev v inhalatorjih z odmerjeno dozo.However, propellants 11, 12 and 114 belong to the class of compounds known as chlorofluorocarbons, which are associated with the release of ozone from the atmosphere. Ozone has been found to retain certain harmful UV rays and that a decrease in ozone content in the atmosphere will lead to an increased incidence of skin cancer. In 1970, some steps were taken to reduce CFC emissions from aerosols. They used other propellants, such as hydrocarbons, or otherwise marketed the product. Because the use of CFC in medical devices is relatively low, i.e. less than 1% of total emissions, and because of the health benefits associated with metered dose inhalers, did not limit the use of CFC propellants in metered dose inhalers at that time.

Vendar so nadaljnje in bolj izpopolnjene meritve ozona nakazale, da so bile prejšnje omejitve uporabe CFC nezadostne in, da je potrebno še dodatno znatno zmanjšati emisijo CFC. Nedavno je bilo priporočeno, da bi do konca stoletja dejansko zaustavili proizvodnjo CFC. Zato ne bo mogoče nadaljevati uporabe CFC pogonskih sredstev v tem času in dolgoročno. Čeprav je bilo vloženega precej truda v uporabo inhalatorjev z odmerjeno dozo brez pritiska, mnoga izmed teh sredstev niso bila popolnoma uspešna. Mnoga ne dostavijo določenih doz in so mehansko kompleksna, ne omogočajo 100-200 doz na enoto sedanjih embalaž aerosolov, so posameznikom težavna za uporabo ter so obsežna in/ali nerodna za uporabo, posebej še, ko imajo pacienti akutno potrebo po zdravilu.However, further and more sophisticated measurements of ozone indicated that previous restrictions on CFC use were insufficient and that significant further reductions in CFC emissions were required. It was recently recommended that by the end of the century, the production of CFCs should actually be stopped. Therefore, it will not be possible to continue using CFC propellants during this time and in the long term. Although considerable effort has been made to use non-pressure metered dose inhalers, many of these agents have not been completely successful. Many do not deliver specific doses and are mechanically complex, do not allow 100-200 doses per unit of current aerosol packaging, are difficult for individuals to use and are bulky and / or awkward to use, especially when patients have an acute need for medication.

Kot rezultat obstaja potreba po formulacijah aerosolov, ki so popolnoma brez CFC. Sistemi pogonskih sredstev brez CFC morajo zadostiti več kriterijev za inhalatorje z odmerjeno dozo pod pritiskom. Morajo biti nestrupeni, stabilni in nereaktivni z zdravilom in drugimi važnejšimi komponentami v ventilu/sprožilu. Pogonsko sredstvo, ki se je izkazalo za primerno, je CF3-CHF-CF3, znan tudi kot Freon 227, HFA 227, HFC 227 ali 1,1,1,2,3,3,3-heptafluoropropan. Kakorkoli že, določene fizikalne lastnosti HFC 227, t.j. polarnost in topnost, se razlikujejo od lastnosti CFC pogonskih sredstev, ki jih uporabljamo običajno. Surfaktanti, ki jih uporabljamo običajno, so lahko v HFA 227 netopni. Še več, kjer moramo dati zdravilo v raztopini, zdravilo ne sme biti dobro topno v tem pogonskem sredstvu. Razlika v polarnosti med HFC 227 in prej uporabljanimi CFC pogonskimi sredstvi lahko povzroči drugačno dostavo zdravila, če CFC zamenjamo s HFC 227 pogonskim sredstvom. V pogonskem sredstvu brez CFC se zdravilo lahko razsloji, posede ali aglomerira, tudi, če se to ni pojavljalo v CFC pogonskem sredstvu.As a result, there is a need for CFC-free aerosol formulations. Propulsion systems without CFCs must satisfy several criteria for metered dose inhalers. They must be non-toxic, stable and non-reactive with the drug and other major components in the valve / actuator. The propellant that has proven to be suitable is CF3-CHF-CF3, also known as Freon 227, HFA 227, HFC 227 or 1,1,1,2,3,3,3-heptafluoropropane. Anyway, certain physical properties of HFC 227, i.e. polarity and solubility differ from the properties of CFC propellants commonly used. The surfactants commonly used may be insoluble in HFA 227. Moreover, where the drug is to be given in solution, the drug should not be well soluble in this propellant. The difference in polarity between HFC 227 and previously used CFC propellants may result in a different drug delivery if CFCs are replaced by HFC 227 propellants. In a non-CFC propellant, the drug may be stratified, possessed or agglomerated even if it did not occur in the CFC propellant.

Uporaba HFA 227 je bila predhodno razkrita za uporabo pri medicinskih inhalatorjih. European Patent Publication No. 0 384 371 je usmerjena k kombinaciji pogonskega sredstva 227 in propana, butana, izobutana, Me2<D in/ali F2CHMe.The use of HFA 227 has been previously disclosed for use in medical inhalers. European Patent Publication 0 384 371 is directed to a combination of propellant 227 and propane, butane, isobutane, Me2 <D and / or F2CHMe.

Research Disclosure No. 30161, maj, 1989 razkriva, da pogonska sredstva brez CFC, kot so fluorohidroogljiki, lahko uporabljamo pri zdravilih pod pritiskom, ki jih dovajamo direktno v pljuča, t.j. bronhodilatatorjih.Research Disclosure No. 30161, May 1989 discloses that non-CFC propellants, such as fluorohydrocarbons, can be used in pressurized drugs that are fed directly into the lungs, i.e. bronchodilators.

Druge publikacije so usmerjene k uporabi drugih fluorohidroogljikov, kot je HFC 134a, za pogonska sredstva aerosolov. European Patent Publication No. 0 372 777 je usmerjena k medicinskim formulacijam aerosolov, ki vključujejo HFC 134a In adjuvans, ki ima višjo polarnost kot pogonsko sredstvo. Ta publikacija našteva več možnih adjuvansov in surfaktantov za uporabo v kombinaciji z zdravilom in s pogonskim sredstvom.Other publications have focused on the use of other fluorohydrocarbons, such as HFC 134a, for propellants of aerosols. European Patent Publication 0 372 777 is directed to aerosol medical formulations comprising HFC 134a And an adjuvant having a higher polarity than the propellant. This publication lists several possible adjuvants and surfactants for use in combination with a drug and a propellant.

International Patent Application No. WO 91/04011 razkriva kombinacijo HFC 134a in zdravila v prahu, ki je pred dispergiranjem v pogonsko sredstvo prej-prekrito z nepertluoriranim surfaktantom. Strani publikacije 6-7 naštevata primerne surfaktante za uporabo s pogonskim sredstvom. Poljubno lahko dodamo perfluoriran adjuvans. Vendar pa je lahko predhodno prekrivanje zdravila neprednostno, ker v proizvodni proces dodaja dodatno kompleksno stopnjo.International Patent Application No. WO 91/04011 discloses a combination of HFC 134a and a powdered drug that is previously coated with a non-fluorinated surfactant prior to dispersion into the propellant. Pages 6-7 list suitable surfactants for use with a propellant. Perfluorinated adjuvant may be added optionally. However, prior overlapping of the drug may be advantageous because it adds an additional complex rate to the production process.

U.S.Patent No. 4 174 295 razkriva kombinacijo HFC 134a z različnimi klorotluoroogljiki in poljubno z nasičenimi ogljikovodiki. U.S.Patent No. 2 885 427 razkriva uporabo HFC 134a za pogonsko sredstvo za aerosole. U.S.Patent No. 3 261 748 razkriva uporabo HFC 134a za anestezijo. U.S.Patent No. 4 129 603, 4 311 863, 4 851 595 in European Publication No. 379 793 tudi razkrivajo uporabo HFC 134a kot pogonsko sredstvo za aerosole.U.S. Pat. 4 174 295 discloses the combination of HFC 134a with various chlorothluorocarbons and optionally with saturated hydrocarbons. U.S. Pat. 2 885 427 discloses the use of HFC 134a for propellant for aerosols. U.S. Pat. 3 261 748 discloses the use of HFC 134a for anesthesia. U.S. Pat. 4 129 603, 4 311 863, 4 851 595 in European Publication No. 3 379 793 also disclose the use of HFC 134a as a propellant for aerosols.

Vendar specifične kombinacije, ki so omenjene zgoraj, lahko ne zagotovijo zaželjene topnosti, stabilnosti, nizke strupenosti, natančnega odmerjanja (doziranja), pravilne velikosti delcev (v primeru suspenzije) in /ali kompatibilnosti z montažami ventilov, ki jih navadno uporabljamo pri inhalatorjih z odmerjeno dozo.However, the specific combinations mentioned above may not provide the desired solubility, stability, low toxicity, accurate dosing, correct particle size (in the case of suspension) and / or compatibility with valve assemblies commonly used in metered dose inhalers dose.

PODROBEN OPIS IZUMADETAILED DESCRIPTION OF THE INVENTION

V vseh formulacijah iz predstavljenega izuma uporabljamo pogonsko sredstvo 227 v kombinaciji z zdravilom, poljubno s tekočim ekscipientom in poljubno s surfaktantom.In all the formulations of the present invention, propellant 227 is used in combination with a drug, optionally with a liquid excipient, and optionally with a surfactant.

Ekscipient omogoča kompatibilnost zdravila s pogonskim sredstvom in tudi znižuje sprožitveni pritisk na sprejemljivo raven t.j. okrog 2.76-5.52x105 N/m^ absolutno (40 do 80 psia), zaželjeno 3.45-4.83x10^ N/m^ absolutno (50 do 70 psia). Izbrani ekscipient mora biti nereaktiven z zdravilom, relativno nestrupen in naj ima parni tlakj pod okrog 4.35x10$ N/m^ absolutno (50 psia). Kakor smo ga uporabili tukaj, se izraz ‘maščobne kisline s srednijimi verigami' nanaša na verige alkilnih skupin, ki se končajo s -COOH skupino in imajo 6-12 ogljikovih atomov, najraje 8-10 ogljikovih atomov. Izraz maščobne kisline s kratkimi verigami se nanaša na verige alkilnih skupin, ki se končajo s -COOH skupino in imajo 4-8 ogljikovih atomov. Izraz alkohol vsebuje C1-C3 alkohole, kot so metanol, etanol in izopropanol. Med zaželjenimi ekscipienti so:Excipient allows the drug to be compatible with the propellant and also lowers the trigger pressure to an acceptable level ie around 2.76-5.52x10 5 N / m ^ absolute (40 to 80 psia), desirable 3.45-4.83x10 ^ N / m ^ absolute (50 to 70 psia ). The selected excipient should be non-reactive with the drug, relatively non-toxic and should have a vapor pressure below about 4.35x10 $ N / m ^ absolute (50 psia). As used herein, the term 'medium chain fatty acids' refers to chains of alkyl groups ending with a -COOH group having 6-12 carbon atoms, preferably 8-10 carbon atoms. The expression of short-chain fatty acids refers to chains of alkyl groups ending with a -COOH group having 4-8 carbon atoms. The term alcohol contains C1-C3 alcohols such as methanol, ethanol and isopropanol. Desirable excipients include:

Kjer morajo zdravilo, ekscipient in pogonsko sredstvo tvoriti raztopino, je surfaktant lahko nujen ali pa tudi ne, odvisno od topnosti določenega zdravila in ekscipienta. Surfaktant je lahko katerakoli primerna, nestrupena spojina, ki je nereaktivna z zdravilom in stvarno znižuje površinske napetosti med zdravilom, ekscipientom in pogonskim sredstvom in/ali deluje kot mazivo za ventil. Med zaželjenimi surfaktanti so:Surfactant can be optionally added to reduce the surface and internal stresses between the drug and the propellant. Where the drug, excipient and propellant must form a suspension, surfactant may or may not be used. Where the drug, excipient and propellant must form a solution, the surfactant may or may not be necessary depending on the solubility of the particular drug and excipient. The surfactant can be any suitable, non-toxic compound that is non-reactive with the drug and actually reduces surface tension between the drug, excipient and propellant and / or acts as a valve lubricant.

Zdravila iz predstavljenega izuma lahko vključujejo vse farmacevtsko aktivne spojine, ki naj bi jih dali z oralno inhalacijo ali nazalno. Tipični razredi spojin vključujejo bronhodilatatorje, antiinflamatorne spojine, antihistaminike, antialergene, analgetike, zdravila proti kašlju, zdravila proti angini, steroide, kortikosteroide, vazokonstriktorje in antibiotike. Specifične spojine v teh razredih spojin so albuterol, mometazon furoat, belkometazon dipropionat, izoproterenol, heparin, terbutalin, rimiterol, perbuterol, dinatrijev kromoglikat, izoprenalin, adrenalin, pentamidin in ipratopij bromid. Te spojine lahko uporabimo kot proste baze ali kot soli ali pa kot klatrate, odvisno od stabilnosti in topnosti aktivne spojine v specifični formulaciji. Ko uporabljamo klatrate, so posebej zaželjeni P-11 in heksanovi klatrati.The medicaments of the present invention may include any pharmaceutically active compound to be administered by oral inhalation or nasal. Typical classes of compounds include bronchodilators, anti-inflammatory compounds, antihistamines, anti-allergens, analgesics, cough drugs, anti-angina drugs, steroids, corticosteroids, vasoconstrictors and antibiotics. The specific compounds in these classes of compounds are albuterol, mometasone furoate, belkometazone dipropionate, isoproterenol, heparin, terbutaline, rimiterol, perbuterol, disodium chromoglycate, isoprenaline, adrenaline, pentamidine and ipratopium bromide. These compounds can be used as free bases or as salts or as clathrates, depending on the stability and solubility of the active compound in a specific formulation. When using clathrates, P-11 and hexane clathrates are especially desirable.

Kjer aktivna spojina tvori suspenzijo, mora biti velikost delcev relativno izenačena, s popolnoma vsemi delci raje v okviru med 0.1-25 pm, še raje 0.510 pm, najraje 1-5 pm. Delci večji od 25 pm se lahko zadržijo v žrelni votlini, medtem, ko delcev manjših od okrog 0.5pm raje ne uporabljamo, ker je večja verjetnost da jih pacient izdihne in tako ne dosežejo pljuč.Where the active compound forms a suspension, the particle size should be relatively uniform, with all particles preferably in the range of 0.1-25 pm, preferably 0.510 pm, preferably 1-5 pm. Particles larger than 25 pm may be retained in the pharynx, while particles smaller than about 0.5pm may not be used because the patient is more likely to exhale and thus not reach the lungs.

Formulacije predstavljenega izuma lahko polnimo v posode za aerosol z uporabo konvencionalne polnilne opreme. Ker je pogonsko sredstvo 227 lahko nekompatibilno z vsemi elastomernimi spojinami, ki jih tekoče uporabljamo pri obstoječi montaži ventilov, je lahko nujno le te nadomeščati z drugimi materiali, kot je bel sintetični kavčuk, ali pa uporabljati ekscipiente in neobvezno surfaktante, ki blažijo ali nasprotujejo učinkom pogonskega sredstva 227 na komponente ventila.The formulations of the present invention can be filled into aerosol containers using conventional filling equipment. Because propellant 227 may be incompatible with all elastomeric compounds that are currently used in existing valve assembly, it may be necessary to replace them with other materials, such as white synthetic rubber, or to use excipients and optional surfactants that mitigate or counteract the effects propellant 227 to valve components.

Za zagotovitev enakomerne disperzije aktivne sestavine bodo formulacije tipično vsebovale komponente, ki sledijo:In order to ensure uniform dispersion of the active ingredient, the formulations will typically contain components as follows:

V odvisnosti od določene uporabe je lahko rezervoar napolnjen s prej določeno količino formulacije za enkratno ali večkratno odmerjanje. Tipično je rezervoar načrtovan za večkratno odmerjanje, zatorej je zelo pomembno, da je formulacija, ki jo dajemo, popolnoma enaka pri vsakem odmerjanju. Na primer, kjer je formulacija za bronhodilatacijo, je rezervoar tipično napolnjen z zadostno količino formulacije za 200 dajanj.Depending on the particular application, the tank may be filled with a predetermined amount of single or multiple dosage formulation. Typically, the reservoir is designed for multiple dosing, so it is very important that the formulation administered is exactly the same at each dosage. For example, where the formulation is for bronchodilation, the reservoir is typically filled with sufficient formulation for 200 administrations.

Primerne suspenzije lahko podvržemo selekciji z opazovanjem nekaterih fizikalnih lastnosti formulacije, t.j. stopnje aglomeracije delcev, velikosti aglomeratov in stopnje razslojevanja/posedanja in primerjavi le teh s sprejetimi standardi. Primerne raztopine lahko podvržemo selekciji z opazovanjem topnosti zdravila čez celotni priporočeni okvir trajanja skladiščenja in temperature.Suitable suspensions can be selected by observing some of the physical properties of the formulation, i.e. the particle agglomeration rates, the size of the agglomerates, and the stratification / settling rate, and comparing them with accepted standards. Suitable solutions can be selected by observing the solubility of the drug over the entire recommended storage life and temperature.

Suspenzije iz predstavljenega izuma najraje pripravimo z obojim, polnjenjem pod pritiskom ali s postopki hladnega polnjenjenja, ki so strokovnjakom dobro znani.The suspensions of the present invention are preferably prepared by both pressurized, pressurized, or cold-fill processes well known to those skilled in the art.

Za inhalatorje z odmerjeno dozo so najbolj zaželjene suspenzije zaradi precejšnje učinkovitosti in stabilnosti.For metered dose inhalers, suspensions are most preferred because of their high efficiency and stability.

Strokovnjaki lahko kot dodatek izberejo eno ali več sredstev za konzerviranje, pufer, antioksidant, sladilo in/ali arome ali druge agenske, ki zakrijejo/maskirajo okus, odvisno od značilnosti formulacije.Experts may opt for one or more preservatives, buffer, antioxidant, sweetener and / or flavors or other agents that mask / mask the taste, depending on the characteristics of the formulation.
