PREFACE TO FIRST EDITION


The Pharmacopeia of the United States and the National Formulary are now
recognized by federal and state laws as standards for drugs and their
preparations. Physicians who prescribe Pharmacopeial or National
Formulary drugs or preparations, therefore, are more likely to obtain a
good and constant quality than if they prescribe unofficial articles,
i.e., articles that have no legalized standard. Hence medical men are
interested in knowing what drugs and preparations are included in these
two books of standards. Both the Pharmacopeia and the National
Formulary, however, contain a vast amount of technical information, of
value to pharmacists but of little interest to physicians. The Journal
of the American Medical Association in 1907 issued the "Physicians'
Manual of the U.S. Pharmacopeia and National Formulary," a book designed
to meet the needs of physicians in this respect. The fact that this book
did meet a real need is evidenced by the continued demand for it.

The present "Epitome of the U.S. Pharmacopeia and National Formulary"
takes the place of that book, but is based on the new (the ninth)
revision of the Pharmacopeia and the new (the fourth) edition of the
National Formulary. It has been prepared under the direction of a
committee appointed by the Council on Pharmacy and Chemistry of the
American Medical Association. The aim has been to include all the matter
in the Pharmacopeia and National Formulary which is likely to be of
interest to physicians. This, it is believed, consists of the official
titles and their abbreviations; synonyms; brief definitions; when
necessary, concise descriptions of the physical properties; and dosage.
Since both the Pharmacopeia and the National Formulary include many
drugs and preparations which are irrational, superfluous or worthless,
in many cases the medical members of the committee have added brief
comments to aid a discriminating selection of therapeutic agents.

In this epitome drugs are arranged alphabetically by Pharmacopeial or
National Formulary titles; preparations of drugs are placed under the
drugs themselves. Thus Tinctura Digitalis is placed not among the Ts,
but among the Ds under Digitalis. Names of drugs are in black-face type;
names of preparations are in light-face italics. An index is added to
assist in ready reference.

Statements of composition refer in some cases to percentage by volume,
in others to percentage by weight, and in still others to percentage by
weight-volume--that is, the weight of a given chemical contained (or the
weight of a given vegetable drug represented by extractives) in 100 Cc.
of the preparation. It has not been thought worth while to indicate
whether the statement in each case is by volume, weight or
weight-volume, since the differences are too small to have any
therapeutic importance. Statements of alcoholic content refer to
percentage by volume and are approximate only. In a few instances in
which the quantity of alcohol in a dose is small, or in which the
preparation is intended for external use, the alcohol content is not
stated.

DOSAGE statements, when followed by the letters "U.S.P." or "N.F.," are
taken from these books, respectively, and are understood to be the
average adult doses. In some cases in which this statement was felt to
be inadequate or unsatisfactory, further suggestions as to dosage have
been added.




PREFACE TO SECOND EDITION


The text of this edition is the same as that of the first, except that a
few typographical errors which were in the first edition have been
corrected.

The new edition differs from the first in the following particulars:

In the first edition, a star indicates that the drug is included in the
second (1916) edition of Useful Drugs. To bring the present edition up
to date, the star (*) here indicates that the drug is included in the
fifth (1921) edition of Useful Drugs.

In compliance with the opinion expressed by some that a more complete
index would be helpful, the index to the second edition has been
materially extended. It is hoped that this will help to familiarize
those who purchase the book with its contents.

AMERICAN MEDICAL ASSOCIATION, PRICE 50 CENTS]


       *       *       *       *       *


=Absinthium (Absinth.), Absinthium, N.F.= (Wormwood, Madderwort,
Vermuth).

     Leaves and flowering tops.

  ACTION AND USES: Obsolete aromatic bitter; without
  advantage over gentian or other bitter drugs.


=*Acacia (Acac.), Acacia, U.S.P.= (Gum Arabic, Gum Senegal).

     A gum occurring in tears, fragments or powder. Slowly and almost
     completely soluble in water and insoluble in alcohol. Incompatible
     with sodium borate, lead acetate and ferric salts.

  ACTION AND USES: Demulcent; chiefly as a vehicle to
  suspend insoluble substances in aqueous mixtures.

_*Mucilago Acaciae (Mucil. Acac.), Mucilage of Acacia, U.S.P._--Acacia
(35%) in water.

  DOSAGE: 15 Cc. or 4 fluidrachms (U.S.P.).

_Syrupus Acaciae (Syr. Acac.), Syrup of Acacia, U.S.P._--Acacia (10%) in
sugar and water.


=ACETA, VINEGARS.=--A vinegar is a solution of vegetable principles
either in diluted acetic acid or in a mixture of diluted acetic acid and
alcohol. For Acetum Aromaticum, see under =Oleum Lavandulae=; for Acetum
Opii and Acetum Scillae, see under =Opium= and =Scilla=, respectively.


=*Acetanilidum (Acetanil.), Acetanilid, U.S.P.= (Acetanilide,
Antifebrin).--C{6}H{5}NH.CH{3}CO.

     A white, odorless, crystalline powder, with a slightly burning
     taste. Slightly soluble in water (1:190), very soluble in alcohol
     (1:3.4) and in chloroform (1:3.7). Incompatible with spirit of
     nitrous ether and forms pasty masses when triturated with chloral
     or antipyrin.

  ACTION AND USES: Analgesic, antipyretic and, in excessive
  doses, a cardiac depressant. Used particularly to
  relieve headache and neuralgic pains. A habit-forming
  drug. If used over a long period of time, it may produce
  a severe anemia.

  DOSAGE: 0.2 Gm. or 3 grains (U.S.P.) in powders
  which may be placed in capsules, or tablets which should
  be crushed before swallowing. It is well to begin with 0.1
  Gm. or about 1-1/2 grains, and to repeat cautiously.

_Pulvis Acetanilidi Compositus (Pulv. Acetanil. Co.), Compound
Acetanilid Powder, N.F._--Acetanilid (70%), caffeine (10%) and sodium
bicarbonate (20%).

  USES: Irrational acetanilid preparation. The caffeine
  does not diminish the toxicity, nor does the bicarbonate
  increase the solubility of acetanilid, as was at one time
  supposed.

  DOSAGE: 0.3 Gm. or 5 grains (N.F.).


=Acetonum (Aceton.), Acetone, U.S.P.= (Dimethyl-Ketone).

     A colorless liquid, with an ethereal odor and a pungent sweetish
     taste. Miscible with water, alcohol, ether and chloroform.

  ACTION AND USES: Pharmaceutic solvent.


=*Acetphenetidinum (Acetphen.), Acetphenetidin, U.S.P.
(Phenacetin).=--C{6}H{4}(OC{2}H{5}).NH.CH{3}CO.

     White, odorless, slightly bitter, crystalline scales or powder.
     Very slightly soluble in water (1:1310), soluble in alcohol (1:15)
     and in chloroform (1:14).

  ACTION AND USES: Analgesic, antipyretic and, in excessive
  doses, a cardiac depressant. Used particularly for
  the relief of headache and neuralgic pains and in the treatment
  of mild fevers. A habit-forming drug. If used for a
  long period of time, it may produce a severe anemia.

  DOSAGE: 0.3 Gm. or 5 grains (U.S.P.), in powders or
  capsules. If small doses fail to relieve headache, larger
  doses are also usually ineffective.


=*Acidum Aceticum (Acid. Acet.), Acetic Acid, U.S.P.=--Acetic acid
CH{3}.COOH (about 36.5%).

  ACTION AND USES: Caustic and rubefacient. In the form
  of vinegar, is antidote to alkalies.

_Acidum Aceticum Dilutum (Acid. Acet. Dil.), Diluted Acetic Acid,
U.S.P._--CH{3}COOH (about 6%).

  DOSAGE: 2 Cc. or 30 minims.

_Acidum Aceticum Glaciale (Acid. Acet. Glac.), Glacial Acetic Acid,
U.S.P._--CH{3}COOH.

     A colorless liquid, with a vinegar-like odor and a pungent, sour
     taste. Miscible with water or alcohol.


*=Acidum Benzoicum (Acid. Benz.), Benzoic Acid, U.S.P.=--C{6}H{5}.COOH.
Obtained from benzoin or prepared synthetically.

     Lustrous, almost colorless scales or needles, with a pungent, acid
     taste. Slightly soluble in water (1:275) and freely soluble in
     alcohol (1:2.3); also readily soluble in solutions of alkali
     hydroxides or carbonates with the production of alkali benzoates.

  ACTION AND USES: Mild antiseptic and diuretic.

  DOSAGE: 0.5 Gm. or 8 grains (U.S.P.), best given in the
  form of soluble benzoates (see under =Sodii Benzoas=).


*=Acidum Boricum (Acid. Bor.) Boric Acid, U.S.P.= (Boracic
Acid).--H{3}BO{3}.

     Colorless, odorless scales or powder with a faintly bitter taste.
     Soluble in water and in alcohol (1:18); freely soluble in glycerin
     (1:4).

  ACTION AND USES: Mild antiseptic and astringent.

  DOSAGE: 0.5 Gm. or 8 grains (U.S.P.), in solution. A
  watery solution, ranging from 2 per cent. to =saturated=, is
  used in the treatment of conjunctivitis, cystitis, etc.
  Externally used as dusting powder.

_*Glyceritum Boroglycerini (Glycer. Boroglyc.), Glycerite of
Boroglycerin, U.S.P._--Boroglycerin in glycerin representing 31% boric
acid.

_Liquor Antisepticus (Liq. Antisept.), Antiseptic Solution, N.F._--Boric

  For disinfecting rooms, from 150 Cc. or 5 fluidounces to 1 quart or 1
  liter of the official formaldehyde solution are allowed to each 1,000
  cubic feet of space by various authorities. Various methods have been
  employed. One is to allow the solution to evaporate from sheets
  suspended in the tightly closed room. Another is to generate the gas
  in the room by treating the solution with potassium permanganate,
  allowing about 110 Gm. or 3-1/2 ounces of potassium permanganate to
  500 Cc. or 1 pint of formaldehyde solution. A third method utilizes
  the reaction between formaldehyde solution and sodium dichromate in
  the presence of sulphuric acid, used in the proportion of 45 Cc. or
  1-1/2 fluidounces of sulphuric acid and 280 Gm. or 9 ounces of sodium
  dichromate to 500 Cc. or 1 pint of formaldehyde solution. These
  methods are not effective if the temperature of the room be below 60
  F. or the relative humidity below 65 per cent.
