Description
Technical field
The present invention relates to a kind of turning capsule powder inhaler opened.
Background technology
From the mid-50 in last century, the inhaler that Charles Thiel invents starts, and people just start, in the treatment of asthma and chronic obstructive disease of lung, to use inhaled drugs aerosol delivery to the medical treatment device of patient.
Relative to administering modes such as oral and subcutaneous injections, inhalation-type drug administration has advantage clearly.Mucomembranous surface due to human body nasal cavity, bronchus and pulmonary is long-pending very large, and the respiratory tract of human body always has 23 bifurcateds, and adult's alveolar surface area can up to 140 square metres, and alveolar wall is very thin, and around gather a large amount of blood capillary.Drug particles can be organized and directly enter blood circulation by fast strikethrough alveolar mucosa wherein.Have without intestines and stomach Degradation, without the first pass effect of liver, dosage little rapid-action, toxic and side effects is low and be applicable to biomacromolecule and the advantage such as send.Lung Sucked medicine is the optimal treatment mode of pulmonary disease such as treatment asthma, chronic obstructive pneumonia etc., and also further expanded to treatment whole body property disease in recent years, as diabetes etc., its market is huge.
Existing suction apparatus has pressurized metered dose inhalers (Pressurized Metered DoseInhaler, pMDI), aerosol apparatus (Nebulizer), Diskus (Dry PowderInhaler, DPI) three kinds of forms.PMDI need use propellant, although at present application be eco-friendly to atmospheric ozone layer without the hydrofluoroalkane of destruction as propellant, it still can bring greenhouse effect; And when using pMDI, need the appropriate cooperation that medicine ejection-patient sucks, otherwise suction efficiency is very low.Aerosol apparatus is that volume is large, the product of non-portable, is generally only applicable to use in hospital or family.And DPI does not need propellant; Medicine dispersion is caused by patient inspiration flow, there is not cooperative effect; And biomacromolecule is under dry powder, its stability is higher.The aerodynamic force dimensional requirement of inhalation-type drug administration to drug particles is higher, aerodynamic force diameter 0.5 ?drug particles between 5 microns can effectively deposit to the place such as lower respiratory tract and alveolar, thus effectively to be absorbed by human body.The granule being greater than 5 microns will deposit to oral cavity, trunnion and upper respiratory tract; And be less than the granule of 0.5 micron, 90% will breathe out with patient expiration external.But 0.5 ?drug particles powder between 5 microns be usually easy to conglomeration, need the optimal design of pharmaceutical engineering technology and inhalant to improve the dispersibility of drug particles.Have an important parameter to be exactly fine granular ratio (FineParticle Fraction, FPF) when assessing the effectiveness of mealy medicine when sucking, it represents in the medicament ejected in inhaler the ratio having an opportunity to deposit in lung.Usually, this ratio is defined as the particle fraction that aerodynamic diameter in medicament is less than 5 microns.
Potion medication amount for sucking generally is less than 50 micrograms, is generally 25-50 microgram.People wish to have higher concordance from the dosage of inhaler sucking-off, and for the medicine of predetermined close, the relative standard deviation (RSD) between each dosage should more than 5%.So existing way generally will need the medicine sucked to make capsule.
Existing its structure of capsule Diskus is relatively complicated, production cost is relative to higher, volume is bigger than normal simultaneously carries inconvenience, and general capsule pierces through direction and is all perpendicular to suction inlet direction, medicated powder need could be blotted only with larger suction, the patient that some suction are on the weak side cannot be used or can not be used completely.
So existing capsule Diskus awaits perfect further.
