Pharmacopoeias. In Chin., Eur. (see p.vii), Int., Jpn, US, and
Viet.
Ph. Eur. 6.2 (Indometacin). A white or yellow, crystalline powder.
Practically insoluble in water; sparingly soluble in alcohol.
Protect from light.
USP 31 (Indomethacin). A pale yellow to yellow-tan, crystalline
powder having not more than a slight odour. It exhibits polymorphism.
Practically insoluble in water; soluble 1 in 50 of alcohol,
1 in 30 of chloroform, and 1 in 40 of ether. Protect from light.
Stability. Indometacin is unstable in alkaline solution.
Indometacin Sodium (BANM, rINNM)
Indometacina sódica; Indométacine Sodique; Indomethacin Sodium
(USAN); Indomethacin Sodium Trihydrate; Natrii Indometacinum.
Sodium 1-(4-chlorobenzoyl)-5-methoxy-2-methylindole-3-
acetate, trihydrate.

C19H15ClNNaO4,3H2O = 433.8.
CAS — 74252-25-8.
Pharmacopoeias. In US.
USP 31 (Indomethacin Sodium). Protect from light.
Incompatibility. Indometacin sodium injection is reconstituted
with preservative-free sodium chloride for injection 0.9% or preservative-
free water for injection. Preparations containing glucose
should not be used; reconstitution at a pH below 6 may cause precipitation of indometacin. Visual incompatibility has
been reported between indometacin sodium injection and tolazoline
hydrochloride,1 7.5 and 10% glucose injection, calcium gluconate,
dobutamine, dopamine, cimetidine,2 gentamicin sulfate,
levofloxacin,3 and tobramycin sulfate.4 A pH below 6 may account
for the visual incompatibility of indometacin sodium and
several of these drugs.

trihydrate with drugs given to neonates by continuous infusion.

with gentamicin sulfate or tobramycin sulfate. Am J

Stability. A reconstituted solution of indometacin sodium
500 micrograms/mL was stable for 14 days when stored at 2° to
6° in either the manufacturer’s original glass vial or in a polypropylene
syringe.1

para hacer la locion lo ideal sería no la sal, sino mas bien la indometacina base.
