A SYNOPSIS OF THE Principles of Combination, AS INVESTIGATED IN THE PRECEDING PAGES, ARRANGED IN A TABULAR FORM SO AS TO AFFORD THE STUDENT AN EASY REFERENCE TO THE KEY LETTERS.
A Synopsis of the Principles of Medicinal Combination.
OBJECT I. TO PROMOTE THE ACTION OF THE BASIS.
Key Letters.
A
A.—By combining the several different forms, or preparations of thesame Substance.
B
B.—By combining the Basis with Substances which are of thesame
Nature, i. e, which are individually capable of producing the same effects,
but with less energy than when in combination with each other.
C
C.—By combining the Basis with Substances of aDifferent
Nature, and which do not exert any Chemical influence upon it, but are found
by experience, or inferred by analogy, to be capable of rendering the stomach, or system,
more susceptible of its action.
OBJECT II. TO CORRECT THE OPERATION OF THE BASIS, BY OBVIATING ANY UNPLEASANT EFFECTS IT MIGHT BE LIKELY TO OCCASION, AND WHICH WOULD PERVERT ITS INTENDED ACTION, AND DEFEAT THE OBJECT OF ITS EXHIBITION.
D
A.—ByCHEMICALLYneutralizing, orMECHANICALLYseparating, the offending ingredient.
E
B.—By adding some substance calculated to guard the stomach, or system against its
deleterious effects.
OBJECT III. TO OBTAIN THE JOINT OPERATION OF TWO, OR MORE MEDICINES.
F
A.—By uniting those Medicines which are calculated to produce theSAME ULTIMATE RESULTS, but by modes of operation totally
different.
G
B.—By combining Medicines which have entirely different powers, and which are
required to obviate different symptoms, or to answer different indications.
OBJECT IV. TO OBTAIN A NEW AND ACTIVE REMEDY, NOT AFFORDED BY ANY SINGLE SUBSTANCE.
H
A.—By combining Medicines which excite different actions in the stomach and system,
in consequence of whichNEW, orMODIFIED RESULTSare produced.
B.—By combining substances which have the property of actingCHEMICALLYupon each other; the results of which are—
I
a. The Formation of New Compounds.
K
b. The Decomposition of the Original Ingredients, and the developement of their
more active elements.
C.—By combining Substances, between which no other change is induced than a
diminution, or increase in theSolubilityof the
principles in which their Medicinal virtues reside.
L
a. By the intervention of Substances that actCHEMICALLY.
M
b. By the addition of Ingredients whose operation is entirelyMechanical.
OBJECT V. TO AFFORD AN ELIGIBLE FORM.
N
a. By which theEfficacyof the Remedy is
enhanced.
O
b. By which itsAspectorFlavouris rendered more agreeable, or its mode of administration
more convenient.
P
c. By which it isPreservedfrom the spontaneous
decomposition to which it is liable.
