-
For a pregnancy to progress naturally to spontaneous labor at term
-
and a successful vaginal delivery,
-
the process of cervical ripening is crucial.
-
if a woman is post date.
-
or when complications arise from mother or child
-
medical intervention may be needed
to induce cervical ripening
-
and ultimately labor.
-
Propess, with its virginal controlled-release delivery system
-
is a well-established treatment
-
to stimulate ripening of the cervix from the 38th week gestation
-
the Propess virginal insert consists of a thin hydrogel polymer matrix
-
within a one-piece polyester pouch and retrieval tape.
-
the active substance Dinoprostonestone is a prostaglandin e2
-
that helps to decrease cirvical rigidity
-
by inducing changes in
the collagen structure in the connective tissue.
-
it also facilitates relaxation of the smooth muscles of the cervix
-
and consequently leads to cervical dilation and defacement.
-
How to use Propess
-
Propess virginal insert is ready to use immediately after removal from the freezer.
-
to open the foil primary pack
-
tear the notch on the side near the top
-
do not use scissors or other sharp objects.
-
now put on a pair of examination gloves
-
and remove the Propess insert
-
gently by pulling at the end of the retrieval tape
-
examine the insert
-
to ensure the plastics slab is safely contained
within the retrieval tape
-
water-soluble obstetric gel may be applied to
the index and middle fingers of one hand
-
now pick up the Propess insert between these two fingers
-
and extend the tape with the other hand
-
gently insert your two fingers into the vagina
-
with the insert securely held between them
-
place the insert high up in the posterior vaginal fornix
-
Then, tongue the retrieval tape just inside vagina
-
this will ensure it is secure from being dislodged inadvertently
-
the retrieval cape may be cut with scissors
-
always ensuring there is sufficient tape
outside the vagina to allow removal
-
after insertion of Propess,
-
the patient is to stay in the recumbent position for 20 to 30 minutes
-
the Propess vaginal insert may remain in place
for a maximum period of 24 hours
-
it should be removed, however, at the onset of labor
-
in cases of spontaneous rupture of membranes or amniotomy
-
evidence of fetal distress
-
evidence of maternal systemic adverse dinoprostone effects
-
such as nausea, vomiting, hypotension or tachycardia
-
and at least 30 minutes prior to starting
an intravenous infusion of oxytocin
-
to remove the propess insert
-
locate the retrieval tape and pull on it gently
-
until the product is fully outside the vagina
-
following removal
-
check if the hydrogel polymers slab
is still inside the retrieval tape
-
this is easily determined of the insert had swollen while in place
-
the half-life of the active substance dinoprostone is around 1 to 3 minutes.
-
ensuring the propess is rapidly cleared from the circulation
-
(Manufacture of thePropess vaginal insert)
-
both the innovative hydro gel polymer technology
-
and the retrieval system for quick removal of propess
-
have been developed at ferring-controlled therapeutics limited in Scotland
-
at this facility the hydrogel polymer insert are formed
-
by chemically cross-linking chains of polyethylene oxide
-
in a three-dimensional lattice
-
the inserts are hydrated
-
and then loaded with ten milligrams of dinoprostone
-
during drying, a matrix contracts and traps the drug, creating a reservoir
-
in a final step
-
the polymer slab is placed into a woven polyester retrieval tape
-
once inside the vagina,
-
the polymer slab absorbs moisture and swells
-
the resulting concentration gradient
-
enables the controlled-release of 0.3 milligrams of dinoprostone
-
every hour over a period of up to 24 hours
-
Summary and safety infomation
-
using the propess vaginal insert has a number of advantages
-
it is easy to administer without the use of stirrups, a speculum or a syringe
-
and provides accurate control of the release of dinoprostone
-
in the location of the cervix.
-
the reservoir of 10 milligrams
-
releases dinoprostone at a contolled and constant rate
-
with the time of vaginal delivery
-
significantly shorter compared to placebo
-
the retrieval system allows fast removal of the Propess insert
-
Propess for initiation of cervical ripening at term.
-
contraindications
-
the propess vaginal insert should not be used
-
or should be removed under the following circumstances:
-
when labor has started
-
when oxytocin drugs are being given
-
when strong prolonged uterine contractions would be inappropriate such as in patients
-
a who have had previous major uterine surgery,
-
e.g. caesarean section, myomectomy, etc.
-
see section 4.4 and 4.8
-
b. with cephalopelvic disproportion
-
c. with fetal malpresentation
-
d. with suspicion or evidence of fetal distress
-
e. who had more than three full term deliveries
-
f. previous surgery or rupsture of the cervix
-
when there is current pelvic inflammatory disease
-
unless adequate prior treatment has been instituted.
-
when there is hypersensitivity to
dinoprostone or to any of the excipients
-
when there is placenta previa or unexplained vaginal bleeding during the current pregnancy.
-
warnings and precautions
-
after insertion of propess,
-
uterine activity and fetal condition must be monitored regularly
-
the vaginal delivery system should be removed from the vagina,
-
if there is any suggestion of maternal-fetal complications,
-
if adverse effects occur,
-
if uterine contractions are prolonged or excessive,
-
if there is possibility of uterine hypertonus or rupture.
-
Propess should be used with caution in patients
-
with ruptured membranes,
-
a previous history of uterine hypertony,
-
glaucoma, asthma,
-
when there is a multiple pregnancy
-
at risk of disseminated intravascular coagulation
-
medication with non-steroidal anti-inflammatory drugs,
-
including acetylsalicylic acid,
-
should be stopped before administration of dinoprostone.
-
Propess should not be administered to
-
patients with a history of previous cesarean section or uterine surgery
-
given the potential risk for uterine
rupture
-
and associated obstetric complications
-
not recommended in patients with diseases
-
which could affect the metabolism
or excretion of dinoprostone,
-
e.g. lung, liver or renal disease.
-
a second dose of propess is not recommended.
-
always consult the full summary of product characteristics before prescribing.
