Abstract
The invention relates to an inhalant containing sodium 2-mercaptoethane sulfonate and ciclesonide and preparation method thereof. The inhalant is composed of ciclesonide and sodium 2-mercaptoethane sulfonate as the active ingredients, and one or more pharmaceutical adjuvants suitable for inhalation drug delivery.
Description
Technical field:
The present invention relates to treat the respiratory tract disease especially medicine of asthma, particularly inhalation powder spray and preparation method thereof.
Background technology:
Asthma is a kind of chronic airway inflammation, it is characterized by Reversible airway obstruction and airway reactivity increases, and the secretions increase that airway obstruction is caused by the bronchial mucosa inflammation, myxedema and two kinds of factors of inflammatory stimulus smooth muscle spasm cause; And airway reactivity to increase also be because the result of the bronchial epithelial cell damage that airway inflammation causes.People recognize to only have the inflammation of control air flue mucosa, just can reach the purpose of final reduction airway hyperreactivity, relieving asthma symptoms.The medicine for the treatment of at present the pulmonary disease such as asthma mainly contains following several: (1) broxaterol, (2) xanthine drug, (3) anticholinergic agent, (4) glucocorticoid, (5) antiallergic agent.China's document " inhaled corticosteroids is for learning and pharmacodynamics " (Wang Changzheng, practical hospital clinical magazine, the 1st phase of the 4th volume January in 2007,16-18) point out, sucking parahormone (ICS) has become the first-line drug of asthma long-term treatment, such as ciclesonide, fluticasone propionate, momestasone furoate, budesonide etc.The document also points out, desirable ICS should be the perfect adaptation of effectiveness and safety, although ICS than the general hormone in existing huge progress aspect the safety for the treatment of, still can not satisfy well the needs of clinical treatment.Long-term, high-dose uses ICS the untoward reaction such as adrenal cortex function inhibition still can occur, and uses separately the ICS (inferior heavy dose) of so-called safe dose can't effectively control severe asthma in the majority.
Mercapto ethylsulfonic acid sodium (CAS, 19767-45-4; Molecular formula, C

Pharmacology embodiment 1
According to Chinese document " airway inflammation disease " (Liu Chuntao, People's Health Publisher, 2004; 506-507) open, SERUM IgE, IL-4, IL-5 occupies critical role in the pathogenesis of asthma, so the serum content with above-mentioned three kinds of factors changes to characterize medicine to the therapeutic effect of Brown-Norway rats with asthma among this pharmacology embodiment.
1, laboratory animal, male wistar rat, age in 6-8 week, body weight 180 ± 20g, 10 every group.Grouping and administration situation such as following table:
1, experimental group 1-4 adopts respectively the aerosol combination that embodiment 5-8 makes, the aerosol combination that experimental group 5-8 adopts respectively embodiment 5-1 to 8-1 to make, what experimental group 9 adopted is the aerosol combination that embodiment 9 makes, during experimental group 10 administration, use first the used pharmaceutical composition administration of experimental group 9, use again the used pharmaceutical composition administration of experimental group 6-1 behind the 15min, not administration of model group.Quantitative valve system according to dosage sealing-in different size.
2, Experimental agents, chicken egg protein (OVA) ((U.S. SIGMA company), deactivation pertussis vaccine (5 * 10
9/ ml)
3, modeling and administration are according to Chinese document " dexamethasone is on the impact of Airway in Asthmatic Guinea Pigs wall thickness " (Wang Luning etc., Chinese Journal of Pathophysiology, 2002,18 (5); Disclosed method is carried out modeling 564-565), and the 1st, model group and each treated animal of experiment (contained OVA10mg, deactivation pertussis vaccine 5 * 10 with 1ml sensitization liquid
9Individual, gel aluminum hydroxide 100mg) lumbar injection sensitization; The 8th repeats sensitization once; Pattern drawing group on the 15th places the atomizing inlet box with each treated animal of experiment, and (60cm * 40cm * 40cm), suck to excite with the 1%OVA solution atomization with ultrasound atomizer once a day puts into 10 rats at every turn, sucks 20min, sucks continuously for eight weeks.Matched group adopts the suction of injecting and atomize of same amount physiologic saline for substitute modeling medicine.Experiment is respectively organized every day and is excited front 30min to adopt the aerosol inhalation, matched group and model group adopt blank HFA134a to replace, the aerosol drug delivery method is: animal is fixed on the operating-table becomes 60-70 ° of placement with level, seal the nostril with adhesive tape, make animal can only per os air-breathing, aerosol nozzle place connects a plastic tube (3cm), the animal tongue is pulled out and plastic tube is extended the throat position, treats that animal is air-breathing to finish administration.
4, after exciting, gets last in the 24h with opening breast under the 1% pentobarbital intraperitoneal anesthesia (40mg/kg), through the right ventricle intubate to pulmonary artery, get middle lobe of right lung after getting express developed with normal saline, place 10% formaldehyde fixing, carry out HE dyeing and under light microscopic, observe the Asthmatic Rat Lung pathology.Get blood survey blood calcium value before facing anesthesia.
5, SERUM IgE, IL-4 and IL5 assay, according to experimental rat model of asthma abdominal aortic blood after anesthesia, in 4 ℃ leave standstill 30min after, with the centrifugal 15min of 1500r/min, collect upper serum, adopt the ELISA method to measure SERUM IgE, the content of IL-4 and IL-5), ELISA test kit (the biological company limited of Wuhan doctor's moral), result such as following table (
N=10)
SERUM IgE, IL-4 and IL-5 content detection result show, compare experimental group 1-4 SERUM IgE with model group, IL-4 and IL-5 content all are decreased significantly (P＜0.01), and compare with the experimental group 5-8 of alone hormone, experimental group 1-4 SERUM IgE, IL-4 and IL-5 content also are decreased significantly (P＜0.05), illustrate that ciclesonide and mercapto ethylsulfonic acid sodium makes the more alone ciclesonide preparation of compound preparation and can produce significant effect to Brown-Norway rats with asthma.And the experimental group of alone mercapto ethylsulfonic acid sodium is compared with model group, and therapeutic effect is also not obvious.Adopt the experimental group 10 of successively administration to compare with the experimental group 2 that adopts the compound recipe administration, also there were significant differences for therapeutic effect, and experimental group 10 is compared with the experimental group 6 of identical hormone dosage, curative effect is basic identical, and it is relevant that this may be that two kinds of active component are made the synergism that compound preparation produces in the treatment.
6, Asthmatic Rat Lung pathological change is observed under the light microscopic, compares with matched group, and model group rat airway wall and smooth muscle obviously thicken, epithelial cell shedding, and inflammatory cell infiltration around reaching in the luminal stenosis, tube wall, collagen deposition increases.The above-mentioned change of experimental group 1-4 obviously alleviates.Experimental group 9 is compared no significant difference with model group, and experimental group 5-8 and the effect that adopts the experimental group 10 of two kinds of active component of inhalation successively be between experimental group 1-4 and experimental group 9, and experimental group 1-4 demonstrates and ciclesonide and mercapto ethylsulfonic acid sodium made the compound preparation Inhalation in Treating airway remodeling of inhibition Brown-Norway rats with asthma has been produced significant synergistic therapeutic effect.
