Description
Technical field
The present invention relates to field of pharmaceutical preparations, particularly inhalant and preparation method thereof and the application of pulullan as the inhalant carrier.
Background technology
Pulmonary delivery system (PDDS) refers to can be with the drug-supplying system of drug delivery to pulmonary, generation part or whole body therapeutic effect.Lung is determined by its physiological structure as new drug delivery place: the adult has 3～400,000,000 alveolars, and the gross area reaches 70～100m
2, and alveolar epithelial cells very thin (0.1～0.2 μ m), the blood capillary that gathers on every side, medicine can be rapidly absorbed and directly enter the body circulation, realizes the purpose of whole body/targeted therapy.Suck form administration with lung, have obvious advantage: 1. without liver first-pass effect, without the gastrointestinal tract Degradation; 2. medicine sucks rapidly, and is rapid-action; 3. can be used for treatment part and whole body property disease; 4. pulmonary's enzymes metabolism activity is low, is the good Non-parenteral Delivery Routes of biomacromolecule, and increases compliance and toleration.5. dosage obviously reduces, and reduces toxic and side effects.
The inhalation-type drug administration approach is the academic therapy for the treatment of respiratory system disease, has been widely used in treatment locality disease such as pneumonia, pulmonary carcinoma, asthma, emphysema, pulmonary cystic fibrosis, chronic obstructive pulmonary disease etc.Found again in the last few years that pulmonary administration is the good approach that realizes that the biomacromolecules such as proteins and peptides are sent, and can realize the effective treatment to systemic disease, and effectively improve patient's compliance.At present, pulmonary is as the drug systemic administration route of the macromolecular drugs such as protein, polypeptide, the vaccine person's that becomes the pharmacy work hot research content, the lung of having developed the biomacromolecules such as insulin, recombinant human somatropin, salmon calcitonin see calcimar, parathyroid hormone, Measles Vaccine sucks preparation and is used for clinical research, and its development space is huge.
The pulmonary administration mode comprises spray (Nebulizer), metered dose inhalation aerosol (pMDI) and Foradil Aerolizer formoterol fumarate (DPI).The spray device is larger, not portable and use; The biological macromolecule solns preparation that sucks for spraying needs cold chain storage and transportation, and is in use easily waited destruction and affect therapeutic effect by ultrasonic.The pMDI preparation needs propellant, although adopt at present hydrofluoroalkane (HFA) replacement fluorine Lyons (CFC) as having eliminated this risk that damages the ozone layer after propellant, but still the tool greenhouse effect; Propellant is influential to the physicochemical property of biomacromolecule isoreactivity medicine, be unsuitable for sending of biomolecule medicine, need the air-breathing cooperative effect that goes out granule with the preparation impelling of patient just can reach good effect when using pMDI, this is for young and old patient and be difficult for row.And DPI is without propellant, to respiratory tract non-stimulated and to environment without any infringement; The ejection of its granule relies on patient's inspiratory airflow to cause fully, thereby has eliminated the air-breathing synergism that causes with device of patient of pMDI; And the biomolecule medicine can more stable preservation under dry powder.Thereby dry powder formulations (claiming again powder spray) is referred to as lung suction preparation of future generation.
Powder spray preparation composition has important function for its dispersibility and lung suction efficiency.The powder spray of using in the market, its adjuvant is lactose.Because lactose has stronger adhesive attraction, cause the lung suction efficiency low, in general, the dosage that in fact can reach pulmonary only has sets 10%～30% of dosage.Therefore, provide a kind of new inhalant adjuvant to have important value for what improve medicine through the lung delivery efficiency.
