DIGITAL IN.-DISINFE C TOL.
Dzgitalin is supposed to be one of the four or five
glucosides (?) existing in the common foxglove (Digitalis
purpurca). Its true chemical nature has not been deter-
Physical Properties.-Digitalin occurs as an amor-
phous crystalline powder.
Therapeutic Applications.-This remedy is employed
in those cardiac diseases in which digitalis itself is indi-
Administration.-The dose of digitalin is from 1
to -1 of a grain (o.ooo6 to 0.0013 gramme).
This name is given to a combination composed of 5
parts of the residue left over in the distillation of crude
naphtha and I part by volume of concentrated sulphuric
acid. This mixture is allowed to cool, and the fluid
portion is finally and gradually combined with an equal
volume of io per cent. soda solution and well shaken.
The mixture appears as a yellowish-brown emulsion.
When used as a disinfectant, disinfectin must be diluted
with four parts of hot water.
This is a mixture of hydrocarbons, soaps, carbolic
acid, and soda.
Physical Properties.--Disinfectol occurs as a brown-
ish-black oily liquid analogous to creolin and lysol. It
has an alkaline reaction and a sp. gr. of i.o86.
I Two other glucosidal principles have been described of late--digitalein
and digiloxin. I)igitalein, whose formula is C1180,, occurs as a yellowish
amorphous powder, freely soluble in water and alcohol. Digitoxin is said
to have a composition of C21120,7, and is a white crystalline body, of a
bitter taste, readily soluble in chloroform, but insoluble in water. The dose
of this principle is put down as from ,-. to 4a of a grain (o.oo0003 to
0.ooo6 gramme) twice a lday. This drug has been highly recommended as
a substitute for digitalis in cardiac disease, being said to act especially upon
the left ventricle.
