Pharmaceutical Gas The gas which are used
in pharmaceutical industry is called the pharmaceutical gas.

Nitrogen
The color of indicators is not affected by the Nitrogen.
Nitrogen can combine with other elements . At high temperature or low temperature nitrogen
can form compounds.

Oxygen it supports combustion. Oxygen also combines with
elements at room temperature. Oxygen also reacts with many
compounds.

Carbon Dioxide
Carbon dioxide is a linear covalent molecule. Carbon dioxide is an acidic oxide and reacts with
water to give carbonic acid. CO2 + H2O ==> H2CO3

any other gas. It is non toxic. It is non-flammable
![Page 25: Physical & chemical properties & uses of pharmaceutical](https://reader031.vdocuments.mx/reader031/viewer/2022021507/58ecc4991a28ab946f8b46eb/html5/thumbnails/25.jpg)
Nitrous Oxide
It is highly soluble in alcohol, ether, oils, and sulfuric acid.
By heating ammonium nitrate, it will decompose into nitrous oxide and water vapor (NH4NO3 (s) → 2 H2O (g) + N2O (g)).

Hydrogen: This gas is used in chemical synthesis and biochemistry.
Ammonia: This gas is used in chemical synthesis and biochemistry.
Nitrous Oxide :Used as gas propeilant for aerosois packaging

Uses of medicinal gas
Carbon dioxide : Carbon dioxide in liquid phase provides
temperatures of down to -76.C and can therefore It can be used for cryotherapy for local analgesia.
Helium : Liquid helium is used to cool the magnets. It also used in modern Magnetic Resonanace.
![Page 28: Physical & chemical properties & uses of pharmaceutical](https://reader031.vdocuments.mx/reader031/viewer/2022021507/58ecc4991a28ab946f8b46eb/html5/thumbnails/28.jpg)
Nitrogen : It is used for cryobiology crytherapy.Nitrous oxide : N2O is used for introduction and maintenance of
inhalational anesthesia in combination with other drugs such as volatile compounds,anesthetics,muscle relaxants analgesic compouns and others.
Oxygen : As oxygen is essential for life.Therefore oxygen is
given for treatment and prevention of a variety of cardiac pulmonary and other diseases.
