Process for preparing musk pain-stopping spray

Abstract

Disclosed is a process for preparing musk pain-stopping spray, wherein the medicinal soup is loaded into purpose-made spraying bottles, the medicine spraying can be operated by hand-operated pressing, the spraying bottles are made of high-density polyethene or PET, the medicament in bottles is in normal pressure state all the time, it has the advantages of convenience in carrying, safety, quantitative spraying and easy control.

Description

1. Technical field: [0001] The invention belongs to the field of medicine for external use, and in particular relates to a preparation method of musk pain-relieving spray. 2. Background technology: [0002] The prescription of Musk Pain Relief Spray comes from the "Musk Pain Relief Liniment" recorded in the first part of the Chinese Pharmacopoeia in 2000. The Musk Pain Relief Liniment is filled with a liquid medicine in a bottle and applied to the affected area when used. The disadvantages of this dosage form are that it is not quantitative and inconvenient to use, it is not easy to apply the liquid medicine evenly, the liquid medicine is easy to come into contact with air and light frequently and is unstable, and it is easy to be polluted after repeated use. [0003] The 2005 edition of Chinese Pharmacopoeia included the musk pain-relieving aerosol again. The musk pain-relieving aerosol is filled with a propellant (freon CF) after filling the liquid medicine in a high-press...

Problems solved by technology

The disadvantages of this dosage form are that it is not quantitative and inconvenient to use, it is not easy to apply the liquid medicine evenly, the liquid medicine is easy to be in frequent contact with air and light, it is unstable, and it is easy to be polluted after repeated use.

[0003] The 2005 edition of Chinese Pharmacopoeia included the musk pain-relieving aerosol again. The musk pain-relieving aerosol is filled with a propellant (freon CF) after filling the liquid medicine in a high-pressure aluminum can and sealing it. 2 Cl 2 ), press the valve when in use, and spray the liquid medicine by the pressure of the propellant. Freon contains chemical elements "fluorine" and "chlorine", which are poisonous to the human body and have a great destructive effect on the ozone layer in the atmosphere. Musk Pain-relieving aerosol uses non-quantitative valves, and the aluminum cans containing the medicine have high pressure and are not resistant to high temperatures. If they are squeezed or collided, they will cause damage and explosion, which is dangerous
