ORTHOFORM—METHYL-PARA-AMIDO-META-OXY-BENZOATE.
Formula.—C.HIOH) (NH2)COOCH3.
Orthoform occurs in the form of a white, voluminous powder,
odorless, and tasteless, and slightly soluble in water.
Therapeutic Action.—Orthoform is antiseptic, hemostatic, and
a local anaesthetic. It is used as a local anaesthetic and antiseptic
to relieve the pain of ulcers, burns, wounds, excoriations, etc.
As it is non-toxic it may be applied to large surfaces ad libitum.
In the form of ointment it is employed to the extent of 10 to 20^
per cent, made up with lanolin. It is also administered internally
in affections of the gastric mucous membrane. Combined with
— "
hydrochloric acid " orthoform hydrochloride — in the form of
a soluble crystalline salt, it anaesthetizes as well as the powdered
orthoform, but is not applicable for subcutaneous injection.
Dose.—Of Orthoform, gr. viii to xv.
Dental Uses.—Orthoform is applied to ulcers, excoriations,
etc., as an antiseptic, and anaesthetic. It is also recommended
for hemorrhage following the extraction of teeth ; after remov-
ing the blood, the alveolar cavity is packed with the powdered
orthoform to arrest the hemorrhage.
A new form of Orthoform (under the name of Orthonew)
has recently been introduced, this new preparation being
whiter and cheaper than the original orthoform. This new prep-
aration is perfectly non-irritating, even when applied in its full
strength, and is used in the same way as the original.
