DESCRIPTION
Polymyxin B Sulfate and Trimethoprim Ophthalmic Solution is a sterile
antimicrobial
solution for topical ophthalmic use. Trimethoprim sulfate,
2,4-diamino-5-(3,4,5-
trimethoxybenzyl)pyrimidine sulfate (2:1), occurs as a white,
odorless, crystalline
powder with a molecular weight of 678.72. The structural formula is as
follows:
Polymyxin B sulfate is the sulfate salt of polymyxin B1 and B2 which
are produced by
the growth of Bacillus polymyxa (Prazmowski) Migula (Fam.
Bacillaceae). It has a
potency of not less than 6,000 polymyxin B units per mg, calculated on
an anhydrous
basis. The structural formula is as follows:
EACH ML CONTAINS:
ACTIVES: Trimethoprim Sulfate equivalent to Trimethoprim 1 mg (0.1%)
and Polymyxin B
Sulfate 10,000 units. Preservative: Benzalkonium Chloride 0.04 mg
(0.004%). INACTIVES:
Sodium Chloride, Sulfuric Acid and Sodium Hydroxide may be added to
adjust pH (3.0 to
5.5), and Water for Injection.
CLINICAL PHARMACOLOGY
Trimethoprim is a synthetic antibacterial drug active against a wide
variety of aerobic
gram-positive and gram-negative ophthalmic pathogens. Trimethoprim
blocks the
production of tetrahydrofolic acid from dihydrofolic acid by binding
to and reversibly
inhibiting the enzyme dihydrofolate reductase. This binding is very
much stronger for
the bacterial enzyme than for the corresponding mammalian enzyme. For
that reason,
trimethoprim selectively interferes with bacterial biosynthesis of
nucleic acids and
proteins.
Polymyxin B, a cyclic lipopeptide antibiotic, is rapidly bactericidal
for a variety of gram-
negative organisms, especially _Pseudomonas aeruginosa_. It increases
the permeability of
the bacterial cell membrane by interacting with the phospholipid
components of the
membrane.
When used topically, trimethoprim and polymyxin B absorption through
intact skin and
mucous membranes is insignificant.
