A kind of antiviral Neulized inhalation pharmaceutical solutions and preparation method thereof
Technical field
The present invention relates to a kind of antiviral Neulized inhalation pharmaceutical solutions and preparation method thereof, belong to galenic pharmacy neck
Domain.
Background technology
Influenza (abbreviation influenza) is ARI caused by influenza virus, is also a kind of biography
The disease that metachromia is strong, spread speed is fast.Its spittle main through the air, interpersonal contact or
With the contact transmission of contaminated article.Typically clinical symptoms are:It is anxious play hyperpyrexia, it is overall pain, significantly weary
Power and slight respiratory symptom.General autumn and winter is its high-incidence season, caused complication and the phenomena of mortality
It is very serious.
Antiviral oral liquor clearing heat and expelling damp, removing pattogenic heat from the blood and toxic material from the body, for anemopyretic cold, influenza.Antiviral oral liquor
Not only have obvious action to the prevention, treatment and control of regional influenza, and to caused by virus other
Disease has significant curative effect.But be administered orally and work slowly, consumption is big, and toxic side effect is larger, therefore urgently opens
The formulation that to send out a kind of safer, allows medicament to be directly entered respiratory tract, dosage is small, rapid-action, reduces
Adverse reaction, improves clinical application safety.
The content of the invention
The present invention solves the technical problem of provide it is a kind of safely, effectively, the antiviral mist of good quality
Change suction pharmaceutical solutions;Present invention also offers the preparation method of said preparation.
The present invention is achieved by the following technical solutions:
A kind of antiviral Neulized inhalation pharmaceutical solutions, including:
(1) antiviral active ingredient;
(2) isotonic agent and solvent;
Buffer solution can also be added.
Wherein, the mass ratio of active ingredient and isotonic agent is 1: 1-1: 5.
The composition (by weight) of active ingredient:
10-15 parts of Radix Isatidis, 3-6 parts of the capsule of weeping forsythia, 4-8 parts of gypsum, 1.5-4.5 parts of the wind-weed, glutinous rehmannia 2-5
Part, 1.5-4.5 parts of grass-leaved sweetflag, 1.5-4.5 parts of root tuber of aromatic turmeric, 1.6-4.8 parts of Pogostemon cablin, 4-8 parts of reed rhizome;
Preferably (by weight):
12.87 parts of Radix Isatidis, 4.65 parts of the capsule of weeping forsythia, 5.72 parts of gypsum, 2.5 parts of the wind-weed, 3.22 parts of glutinous rehmannia,
2.50 parts of grass-leaved sweetflag, 2.50 parts of root tuber of aromatic turmeric, 2.86 parts of Pogostemon cablin, 6.08 parts of reed rhizome;
The preparation method of active ingredient is:
Nine taste medicines are weighed according to above-mentioned parts by weight, secondary, 3 hours first times is added water to cook, collects volatile oil,
Included with HYDROXYPROPYL BETA-CYCLODEXTRIN, or 1.5 hours for the first time, while collecting volatile oil and volatile oil milkiness
Liquid;Second 20 minutes 1 hour, filtration, filtrate merged, be concentrated into it is appropriate, plus 85% more than ethanol
It is 70% to make alcohol content, is stood, and filtration, filtrate recycling ethanol is simultaneously concentrated into thick paste, adds volatile oil clathrate compound
Or volatile oil, volatile oil emulsion are added, obtain the active ingredient of the present invention;
Above volatile oil, volatile oil emulsion also can use solubilizer (such as:Tween 80) dissolving after add thick paste
In.
Isotonic agent is in sodium chloride, potassium chloride, magnesium chloride, calcium chloride, glucose, xylitol, sorbierite
One kind.
Buffer solution be citric acid-sodium citrate, citrate-phosphate disodium hydrogen, potassium dihydrogen phosphate-disodium hydrogen phosphate,
One kind in citric acid-sodium hydroxide, citric acid-disodium hydrogen phosphate.
Appropriate flavouring can also be added in the present invention.
The pH value of aerosol inhalation solution is 3.0-8.5;Preferable ph is 4.0-7.0.
The consumption of aerosol inhalation solution is 0.01-1.0 times of antiviral oral liquor consumption;Preferable amount is disease-resistant
0.05-0.8 times of malicious oral liquid consumption;More preferably consumption is 0.1-0.5 times of antiviral oral liquor consumption.
Antiviral Neulized inhalation pharmaceutical solutions of the present invention can be used for treatment anemopyretic cold, influenza etc..
It is an advantage of the present invention to provide a kind of novel form better than antiviral oral liquor, said preparation is directly by exhaling
Road suction is inhaled, in localized clusters into higher concentration, and the receptor or target acceptor of airway surface is directly acted on
And play a role, and can directly be absorbed from air flue mucous membrane and lung, the administering mode can be straight by effective component
Connect and be delivered to focus, safely and effectively, bioavilability is high, can realize low dosage and fast and effectively treat,
Thus have a clear superiority.
Pharmaceutical solutions prepared by the present invention compensate for the blank on domestic market, can prevent due to a lack of suction
Enter to treat special preparation medicine.And pharmaceutical solutions prepared by the present invention is to aim at Neulized inhalation to be set with patient
Meter, is supported the use with atomizer, convenient using process, compared with antiviral oral liquor, and method of administration is different,
Dosage is reduced, and security is improved.
Beneficial effects of the present invention are further illustrated below by way of test example:
Prepare influenza rat model 80, be randomly divided into Normal group, positive controls, medicine group one,
Medicine group two, medicine group three, medicine group four, medicine group five, medicine group six, every group 10, wherein, just
Normal control group gives normal saline gavage;Positive controls give antiviral oral liquor gavage;Medicine group
First, two, three, four, five, six antiviral aerosol inhalation solution is given respectively (consumption is respectively antiviral mouth
Take 0.01 times, 0.05 times, 0.1 times, 0.5 times, 0.8 times, 1.0 times of liquid), successive administration 3 days,
Observation after treatment, after the cure rate of each group, adverse reaction rate, and last dose lung tissue and
Peak concentration of drug in blood.Specifically it see the table below:
Situation after the treatment of table each group
It can thus be seen that each medicine group has preferable therapeutic action to influenza rat, wherein medicine group
Therapeutic effect is substantially better than positive controls, and does not have adverse reaction.
In summary, medicine group dosage is small, and adverse reaction is few, and medicine it is main lung be gathered into compared with
High concentration, is conducive to effective component to directly act on focus, and bioavilability is high, realizes low dosage and fast
Fast effective treatment, thus have a clear superiority.
Equally, the effect of medicine group treatment anemopyretic cold is also significantly better than antiviral oral liquor.
The therapeutic effect of the antiviral aerosol inhalation solution of the present invention is substantially better than antiviral oral liquor, has filled up mesh
The blank of antiviral special aerosol inhalation solution on preceding domestic market, compared with antiviral oral liquor, is used
Dosage greatly reduces, and is 0.01-1.0 times of antiviral oral liquor, preferably 0.05-0.8 times, more preferably
For 0.1-0.5 times, while changing method of administration, the generation of adverse reaction is reduced, therefore, present invention tool
It is standby creative with prominent substantive distinguishing features and significantly progressive.
