Description

For using the method and composition of oxibutynin
The present invention generally relate to use the new method of oxibutynin, the new model of oxibutynin and be designed for through lung approach send containing the novel form of oxibutynin.More specifically, the present invention includes the new model of the oxibutynin of the effective agent combination with one or more pharmacy.The present invention will describe especially in the following areas: lung is sent oxibutynin and is used for the treatment of respiratory system disease such as asthma and chronic obstructive pulmonary disease (COPD), although also consider other purposes such as preventative, therapeutic or improvement process incontinence and intestinal hypermotility (intestinal hypermotility) i.e. irritable bowel syndrome.
Oxibutynin is the racemic compound of chemical formula 4-diethylamino fourth-2-butyne base phenylcyclohexyl-oxyacetate:
Oxibutynin is the anticholinergic agents of overactive bladder (be hereafter called separately and be generically and collectively referred to as " urge incontinence ") being used for the treatment of urinary incontinence, urge incontinence, frequent micturition and incontinence traditionally.Oxibutynin is worked by the muscle spasm reducing bladder.The m-AChR of its antagonism of competition ground M1, M2 and M3 hypotype.It also has more weak direct spasmolysis to smooth muscle of bladder as calcium antagonist and local anesthetic, but far away higher than under the concentration of Clinical practice.It can be common dosage form and with the form of chloride salt with trade name with form and with the form of transdermal product, with in trade name under patch or with at trade name GELNIQUE tMunder gel form per os utilize.
Oxibutynin now with the form of tablet or multi-disc agent and syrup with oral preparation drug administration or with the form transdermal administration of patch or topical gel agent for treating urge incontinence.But the oral delivery of the oxibutynin of therapeutic activity amount has many shortcomings:
(1) with the oxibutynin of oral preparation drug administration change metabolism and undesirably high close rate situation under with less desirable slow and uneven speed from intestinal absorption, the metabolism wherein changed causes the less desirable change of blood level, and undesirably high close rate obtains therapeutic response and causes less desirable side effect;
(2) within the time that expectation is short, the high blood level of expectation is not produced with the oxibutynin of oral preparation drug administration;
(3) can cause not arriving target tissue in a large number with the oxibutynin of oral preparation drug administration, because it is consumed by metabolism or excretion;
(4) patient thus blocking malfunction to trouble gastrointestinal with the oxibutynin of oral dosage form administration due to the danger that there is urine retention is taboo; With
(5) need Chronic Administration with significant and serious side effect with the oxibutynin of oral preparation drug administration, comprise dry mouth (xerostomia), constipation, platycoria, blurred vision, drowsiness, nauseating, cardiopalmus, tachycardia and dizziness.
(6) stand first pass metabolism with the oxibutynin of oral preparation drug administration, cause the formation of metabolite N-desethyloxybutynin (DEO), this is the reason causing aforementioned most of side effect.
As a result, many patients have interrupted the treatment of per os anticholinergic.These untoward reaction are relevant to the relative high levels of the primary metabolite DEO of oxibutynin, and it is with the concentration circulating of about 4 (oxibutynin ER) to 10 (oxibutynin IR) parent compound doubly.Prove that DEO has higher affinity and in conjunction with the persistent period than the receptor of oxibutynin in salivary gland.In other words, proved that metabolite DEO has higher side effect and effect ratio than parent compound oxibutynin.The DEO level had been reported in per os and skin-penetrating therapeutic is respectively about 10-40ng/mL and 3ng/mL.In order to eliminate the side effect of this medicine completely, reduce DEO level in systemic circulation to will be favourable lower than the existing level (namely lower than 3ng/mL) found in the treatment.
And the oral administration of present oxibutynin also has other shortcoming, comprising:
(7) with the oxibutynin of oral dosage form administration with the form administration of tablet or multi-disc agent, it may lack the convenient drug administration of expectation, because some may not like swallow tablet, or the difficulty of swallow tablet may be had, or can not swallow tablet, or liquid may be needed to help swallow tablet; With
(8) tablet containing oxibutynin is also containing several non-active ingredient, comprise a large amount of lactose, corn starch, magnesium silicate, magnesium stearate and Pulvis Talci, these may be considered to less desirable, because some may not like in these non-active ingredients, one or more comprise oxibutynin tablet or irritated to it.
The transdermal delivery of oxibutynin has aforesaid many shortcomings.In addition, some patients suffer the skin irritation from transdermal patch, have any problem and keep and restrain oneself contacting of patch and skin, or do not like the aesthetics of transdermal patch.
Bronchoconstriction, pneumonopathy, as the mark of chronic obstructive pulmonary disease and asthma, comprises airway narrows (bronchus and bronchioles) in the lung that shrinks due to flesh.Usual flesh contraction is the result of muscarinic receptor activation on smooth muscle cell membrane.This causes the restriction of air flowing turnover lung and causes short of breath and overall dyspnea.
Pneumonopathy includes but not limited to, acute bronchitis, adult respiratory distress syndrome (ARDS), asbestosis, asthma, pulmonary atelectasis, aspergilliosis, bronchiectasis, bronchiolitis, bronchopulmonary dysplasia, byssinosis, chronic bronchitis, coccidioidomycosis, chronic obstructive pulmonary disease (COPD), cystic fibrosis, emphysema, eosinophilic pneumonia, Hantavirus pulmonary syndrome, histoplasmosis, people's Metapneumovirus, hypersensitivity pneumonitis, influenza, pulmonary carcinoma, Lymphangiomatosis, mesothelioma, necrotizing pneumonia, Nontuberculosis mycobacteria (nontuberculosis Mycobacterium), pertussis, hydrothorax, pneumoconiosis, pneumonia, primary ciliary dyskinesia, primary pulmonary hypertension, pulmonary hypertension, pulmonary fibrosis, Pulmonary Vascular is sick, respiratory syncytial virus, sarcoidosis, Severe Acute Respiratory syndrome, pneumosilicosis, sleep apnea, sudden infant death syndrome, and tuberculosis.Modal pneumonopathy generally includes asthma, bronchitis, COPD, emphysema and pneumonia.
In all pneumonopathy, the most general seemingly COPD.Estimate in 2004 according to World Health Organization (WHO), 64 million peoples have COPD and 3 million peoples die from COPD.WHO predicts the year two thousand thirty COPD will become the whole world the 3rd underlying cause of death.Merck Manual (2011) provides to be had COPD the U.S. 1,000 2 million people and describes the COPD as the 4th underlying cause of death, and at 1980 52,193 people's death are compared, and cause at 2003 122, and 000 people is dead.From 1980 to 2000 years, COPD mortality rate increased by 64% (from 40.7 to 66.9/100,000).Sickness rate, incidence rate and mortality rate increased with the age, although and sickness rate is higher in man, general mortality rate is similar in two kinds of sexes.Incidence rate and mortality rate usually Caucasian, blue-collar worker, be subject in the people of more juvenile regular education higher, probably because these colonies have higher smoking prevalence rate.Because increasing in developing country's smoking, due to the mortality rate reduction of infectious disease and widely using of biomass fuel, COPD is more and more in the whole world.
The therapeutic agent of present COPD mainly comprises the bronchodilator through inhalation, comprises the β that induction type is long-acting 2-agonist (LABA) or long-acting muscarine antagonist (LAMA).Although oxibutynin is a kind of LAMA, also do not develop the effective medicament forms with oxybutynin therapy COPD or medication up to now.The disease of known many respiratory tracts responds to the treatment by direct administering therapeutic agent.Because these reagent obtain the most in dry powder form, therefore their most convenient of using has been come by per nasal or mouth inhalation of dust material.This powder type can cause the more good utilisation of medicine, because medicine is accurately deposited on the site of expectation and it may need the place that acts on; Therefore, the atomic little dosage of this medicine is usually equally effective with the larger dose passing through alternate manner administration, and result is that the incidence rate of less desirable side effect and medicine cost significantly reduce.In addition, the medicine of dry powder form may be used for treating the disease except respiratory system or pulmonary system.When medicine deposits on the very high surface area of lung, it may very fast absorbing in blood flow go; Therefore, this application process can replace the administration by injection, tablet or other usual manner.
Although considered the ditropan XL compositions administration in dry powder form of some forms, this form was not also had successfully to put into practice.Still the clinical effective oxybutynin therapy compositions with having approximate physiological chemical property is needed.
Therefore, need sending of the oxibutynin improved, compared with oral or transdermal dosage form, the active onset that it can provide the bioavailability of increase, minimized blood level changes and obtain faster, and compare with transdermal delivery means with the present per os using oxibutynin simultaneously relative convenient drug administration and the side effect of reduction are provided.
Aforementioned object of the present invention and other object by provide by oxibutynin through lung be delivered to mammalian hosts, particularly people patient method and composition, while above-mentioned and other shortcoming avoiding per os and transdermal administration, provide the quick absorption of oxibutynin thus and realize.More specifically, the present invention relates to and be used for the treatment of novel form and the compositions that lung and respiratory system disease include but not limited to the oxibutynin of chronic obstructive pulmonary disease and asthma.In certain embodiments, the invention still further relates to the physiological function obstacle improving and cause the basis of pneumonopathy.The invention provides by using in check site to send specific air flue therapeutic agent being effectively applied to lung.
More specifically, the present invention has been found that compositions containing oxibutynin is effectively applied to mammal reacts with excitation therapy systemic metabolism product is significantly reduced while by sending with the lung of lower dosage level.Should be appreciated that the significant contributor of the detrimental effect of oxibutynin is the system level of metabolite DEO.The contribution of DEO to the increase of side effect is due to its affinity higher to the receptor in non-target tissue and salivary gland.In addition, compare with transdermal administration process with the traditional per os being used for the treatment of urinary incontinence, the present invention can provide the bioavailability of increase, the convenience obtaining active onset faster and use.The lung of oxibutynin sends the alleviation and treatment urinary incontinence and treatment stress urinary incontinence and intestinal hypermotility (intestinal hypermotility) the i.e. alleviation of irritable bowel syndrome that provide treatment respiratory system disease such as chronic obstructive pulmonary disease (COPD) and asthma.The present invention also provides the new model of oxibutynin and uses novel form and the therapeutic scheme of oxibutynin.

The lung of oxibutynin can be advantageously used to be delivered to the symptom of respiratory tract therapeutic respiratory tract disease, urge incontinence and stress urinary incontinence.From there is remarkable side effect need Chronic Administration and need a few hours to reach traditional oxibutynin per os of therapeutic activity blood level different with transdermal delivery, the dry powder lung of oxibutynin is sent and is allowed patient to enjoy remarkable compared with the side effect simultaneously of the alleviation under low dosage reduction as corresponding in dry mouth.The dry powder lung of oxibutynin sends the symptom alleviation also allowing patient to enjoy stress urinary incontinence more immediately or as required.Similarly, the dry powder lung of oxibutynin sends the preventative alleviation allowing patient to obtain respiratory distress symptom as required.
The features and advantages of the present invention of being sent generation by the lung of oxibutynin are being formed of the typical primary metabolite avoiding DEO widely, and this is the adverse side effect produced by it as mentioned above.
In addition, we have found that some salt of oxibutynin, produce when sending administration through lung than the oral delivery half-life be only 2.5 little time expection the significantly more long-acting effect of effect.These salt comprise the new salt form of oxibutynin, the xinafoate of the oxibutynin namely also do not reported in the literature up to now.Such as, the medication of all oxibutynin, because relatively short half-life of 2.5 hours are simultaneously the plateau of about eight (8) little medicines minimally constantly, typically is every day three times.On the other hand, the lung of oxibutynin salt sends the persistent period unexpectedly providing maximum 18 hours activity in Guinea pig lung, and it is converted into people's dosed administration every day one to twice.This shows in fig. 1.
The xinafoate of oxibutynin reacts to prepare by making oxibutynin and former times naphthoic acid (xinafoic acid) under inertia (nitrogen) atmosphere in methyl tertiary butyl ether(MTBE).Other oxibutynin salt sending administration by lung comprises palmitate, pamoic acid, resinate, laruate and stearate, also comprise the ester of oxibutynin (oxybutnin), and beyond thought result can be produced: the metabolite of the half-life of improvement and the bad of reduction produces.
Be used for the treatment of in the preferred configuration of the oxibutynin of administration in selection, the present inventor considers several character of various oxibutynin salt, includes but not limited to following:
