Abstract
The invention belongs to field of pharmaceutical preparations, and in particular to a kind of dextromethorphan hydrobromide and the compound oral solution of PHENYLEPHRINE HYDROCHLORIDE and preparation method thereof.Dextromethorphan hydrobromide is clinically widely used in the various types of coughs for the treatment of, neo-synephrine is vasoconstrictor, respiratory mucosa oedema can be reduced, increase the drainage of sinus cavities, this compound oral pharmaceutical solutions can be used for catching a cold caused cough, nose or throat is itched, shed tears, having a stuffy nose, reducing nasal meatus swelling.
Description
Technical field
The invention belongs to field of pharmaceutical preparations, and in particular to deoxygenate adrenal gland containing dextromethorphan hydrobromide and hydrochloric acid to a kind of
The compound oral solution and preparation method thereof of element.
Technical background
Dextromethorphan hydrobromide is a kind of central antitussive, mainly inhibits the coughing centre of medulla oblongata and plays a role, leads to
The sensibility for reducing intrapulmonary sensory nerve is crossed, under therapeutic dose, the effect of unrestraint breathing and respiratory mucosa secretion, not exclusively
Inhibit cough reflex, without additive, clinic is mainly used for dry cough caused by flu and a variety of causes or has phlegm and excessively frequent
Cough caused by acute cough is a kind of safely and effectively antitussive medicine, and the affinity of dextromethorphan hydrobromide and its receptor is lower, controls
Adverse reaction is less under treatment dosage, and safe range is wide, and neural and Psychotoxicity and cardiovascular response are seldom, is used for a long time without habituation
Property and tolerance, children and old man can be used, also have and do not increase fetus terateger rate using this product during document report gestation;
PHENYLEPHRINE HYDROCHLORIDE be ɑ 1-ADR excitomotor, it is very faint to the effect of β-ADR, act on it is similar to NA but
It is weaker, but since chemical property stablizes event persistent, predominantly vasoconstriction, increase blood pressure;It is mucocutaneous, internal organ such as kidney
It is reduced with the blood flow of lung and four limbs.It is a kind of powerful vasoconstrictor, is used as nasal decongestant and electrocardio agent, goes
Oxygen adrenaline also results in Pulmonary Vascular contraction and subsequent pulmonary artery pressure increases, the vessel retraction under respiratory mucosa
Oedema can be reduced, the drainage of sinus cavities is increased.
The current product of dextromethorphan hydrobromide has tablet, capsule etc., and it is husky containing the right U.S. of hydrobromic acid that the present invention relates to one kind
Sweet smell is free of pigment in the compound oral solution, while antioxidant is added with the compound oral solution of PHENYLEPHRINE HYDROCHLORIDE, shows
Work reduces chemical explanation.Compared with other solid dosage forms, two kinds of drugs are significant in efficacy under therapeutic effect, and this product water solubility is good
Well, the advantages that Small side effects have convenient to take, compliance height, are conveniently adjusted dosage is especially suitable for children and the elderly's clothes
With;It joined corrigent appropriate in this oral administration solution simultaneously, can suitably cover the poor taste of drug, substantially increase children
And the compliance of the elderly's medication.
Summary of the invention
It is an object of the invention to: a kind of dextromethorphan hydrobromide without pigment is provided and PHENYLEPHRINE HYDROCHLORIDE is multiple
Square oral solution formulation and preparation method thereof.
Wherein, every 1ml contains dextromethorphan hydrobromide 0.5-2mg and PHENYLEPHRINE HYDROCHLORIDE 0.5-2mg, and antioxidant contains
Amount is 5-20mg.
Oral administration solution pH of the invention is 2.5-6.5, and preferably pH is 3.0-5, and more preferable pH is 3.5.The inventors discovered that
The compound oral liquid is more stable at low ph conditions, especially in the case where using low content buffer as pH adjusting agent, sample
Product are more stable.
The pH adjusting agent can be organic or inorganic edible acid and its salt.The organic or inorganic edible acid is selected from
One of citric acid and its salt, potassium hydroxide, sodium hydroxide, phosphoric acid and its salt form are several.Preferably citric acid and its
The form of salt forms buffer solution.
The bacteriostatic agent is benzoic acid, sodium benzoate, one of sorbic acid, potassium sorbate or several.
The corrigent is in sucrose, Sucralose, Steviosin, saccharin sodium, sorbierite, maltitol and mannitol
It is one or several kinds of;Refiner essence is added in solution simultaneously, increases aromatic odor, selectable essence fruit essence, strawberry
One or more of essence, orange essence, lemon extract, flavoring pineapple essence, sweetener, fragrant refiner be able to solve patient according to
From property, children, infant are easier to receive.
The solvent is by one or several kinds of in water, ethyl alcohol, propylene glycol, glycerol.It is preferred that water, propylene glycol, glycerol form
Double solvents.
Another aspect of the present invention provides a kind of compound oral containing dextromethorphan hydrobromide and PHENYLEPHRINE HYDROCHLORIDE
The preparation method of solution includes the following steps: to take suitable purified water, pH adjusting agent is added, stirs and be added to after being completely dissolved
Dextromethorphan hydrobromide and PHENYLEPHRINE HYDROCHLORIDE;After adding corrigent, bacteriostatic agent dissolution completely, refiner, molten is added
Agent is uniformly mixed;Finally it is settled to full dose with purified water, after filtering to obtain the final product.
The utility model has the advantages that
The present invention contains dextromethorphan hydrobromide and corrigent, mouth is added in the compound oral solution of PHENYLEPHRINE HYDROCHLORIDE
Sense preferably, is particularly suitable for children.
The present invention uses pH adjusting agent buffer system, makes the pH stable of product, increases bacteriostatic agent, can prevent microorganism
Growth, significantly reduces chemical degradation.
The compound oral stability of solution of the present invention from the dextromethorphan hydrobromide and PHENYLEPHRINE HYDROCHLORIDE is high,
Antioxidant is added, significantly reduces chemical degradation.
It is provided by the invention to prepare work containing the compound oral solution of dextromethorphan hydrobromide and PHENYLEPHRINE HYDROCHLORIDE
Skill is simple, quality controllable, low production cost, is suitble to large-scale production.
