Physical & Chemical Properties & Uses Of Pharmaceutical &
Medicinal GasBy Zisan Ahmed Ziko
GAS
Gas is one of the four fundamental states of matter.
Example of gases
Oxygen Nitrogen Carbon Dioxide Florine Hydrogen
Pharmaceutical Gas The gas which are used
in pharmaceutical industry is called the pharmaceutical gas.
Example of Pharmaceutical Gas :
Nitrogen Oxygen Carbon Dioxide Ozone Hydroge
Physical Properties Of Pharmaceutical gas
Nitrogen:
Nitrogen gas is generally inert. It is a colorless gas. It has no Taste. Melting point -210° C Boiling point -196° C
Oxygen
Oxygen exists in all three forms - liquid, solid, and gas.
oxygen gas is colourless, Tasteless. Boiling point -182.96°C Melting point -218.4°C.
Carbon Dioxide
Carbon dioxide is a colourless gas. It is soluble in water . Melting Point : -55.6 degC Boiling Point : -78.5 degC Density : 1.977
Chemical Properties Of 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
Uses of pharmaceutical gas
Nitrogen: Nitrogen is used for Inerting Lyophilisation Drying Liquid phase transfer
OxygenOxygen is Used for Chemical synthesis Low temperature storage Cyro condensation of waste gases In fermentation
Ozone : Used in chemical synthesis Uses in cyro grinding Low temperature storage
Carbon Dioxide :It is used for Inerting Chemical synthesis Extration Transportation of products
Medicinal Gas
Medical gases fall the definition of drugs and such must be treated as pharmaceutical products
Example
Helium Nitrogen Nitrous Oxide Halothane Oxygen Calibration of devices Carbon Dioxide
Physical Properties Of Medicinal Gas
Xenon
Xenon is a colorless. It is odourless gas. It has a boiling point of -108.13°C (-162.5°F)
Nirous Oxide
Color: colorless Odor: slightly sweet melting point -90.81 oC boiling point -88.46 oC
Helium
Helium is a colorless. It is odorless. It is a tasteless gas. Boiling point -268.9°C The freezing point of helium is -272.2°C
Chemical properties of Medicinal gases
Helium It is less soluble in water than
any other gas. It is non toxic. It is non-flammable
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.
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.
