----------
PERIOCHIP 2.5MG
(CHLORHEXIDINE GLUCONATE)
DESCRIPTION
PerioChip® (chlorhexidine gluconate) is a small, orange-brown,
rectangular chip
(rounded at one end) for insertion into periodontal pockets. Each
PerioChip weighs
approximately 6.9 mg and contains 2.5 mg of chlorhexidine gluconate in
a biodegradable
matrix of hydrolyzed gelatin (cross-linked with glutaraldehyde).
PerioChip also contains
glycerin and purified water.
Chlorhexidine gluconate is an antimicrobial agent. Chemically, it is
designated as 1,1'-
hexamethylenebis [5-(_p_-chlorophenyl)biguanide] di-D-gluconate, and
its molecular
formula is C
H
Cl
N
.2C H
O . The molecular weight is 897.8. The structural
formula of chlorhexidine gluconate is:
CLINICAL PHARMACOLOGY
MICROBIOLOGY
Chlorhexidine gluconate is active against a broad spectrum of
microbes. The
chlorhexidine molecule, due to its positive charge, reacts with the
microbial cell surface,
destroys the integrity of the cell membrane, penetrates into the cell,
precipitates the
cytoplasm, and the cell dies. Studies with PerioChip showed reductions
in the numbers
of the putative periodontopathic organisms _Porphyromonas
(Bacteroides) gingivalis,_
_Prevotella (Bacteroides) intermedia, Bacteroides forsythus,_ and
_Campylobacter rectus_
_(Wolinella recta)_ after placement of the chip. No overgrowth of
opportunistic organisms
or other adverse changes in the oral microbial ecosystem were noted.
The relationship
of the microbial findings to clinical outcome has not been
established.
PHARMACOKINETICS
PerioChip releases chlorhexidine _in vitro_ in a biphasic manner,
initially releasing
approximately 40% of the chlorhexidine within the first 24 hours and
then releasing the
remaining chlorhexidine in an almost linear fashion for 7-10 days.
This enzymatic release
rate assay is an experimental collagenase assay that differs from the
Regulatory
Specification's Agar Release Rate Assay. This release profile may be
