Per l'uso in cheratocongiuntivite e cheratite causata da virus herpes simplex.

In idoxuridina struttura chimica si avvicina molto la configurazione di timidina, uno dei quattro elementi costitutivi del DNA (materiale genetico del virus Herpes). Di conseguenza, è in grado idoxuridina per sostituire timidina nel passaggio enzimatico di replicazione virale o di "crescita". La conseguente produzione di risultati del DNA difettoso in un pseudostructure che non possono infettare e distruggere i tessuti. In breve, la pre- svuotare un elemento vitale nel materiale genetico del virus Herpes simplex, Herplex-D soluzione topica distrugge la capacità infettiva e distruttiva del materiale virale. Il virus infetta cella può essere attaccato solo durante il periodo della sintesi del DNA attiva. Ciò si verifica durante lo sviluppo iniziale del Herpes simplex lesione, ma in tempi diversi in celle diverse. Quindi, idealmente, , L'area interessata deve rimanere saturato con l'agente antivirale.

Description
Idoxuridine (eye-dox-YOOR-i-deen) belongs to the family of medicines called antivirals.
Idoxuridine is used to treat virus infections of the eye.

Idoxuridine is available only with your doctor's prescription, in the following dosage forms:

Ophthalmic
Ophthalmic ointment (U.S. and Canada)

Proper Use of This Medicine
For patients using the eye drop form of idoxuridine:

The bottle is only partially full to provide proper drop control.
To use:
First, wash your hands. Then tilt the head back and pull the lower eyelid away from the eye to
form a pouch. Drop the medicine into the pouch and gently close the eyes. Do not blink. Keep the
eyes closed for 1 or 2 minutes to allow the medicine to come into contact with the infection.

If you think you did not get the drop of medicine into your eye properly, use another drop.
To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface
(including the eye). Also, keep the container tightly closed.

For patients using the eye ointment form of idoxuridine:

To use:
First, wash your hands. Then pull the lower eyelid away from the eye to form a pouch. Squeeze a
thin strip of ointment into the pouch. A 1-cm (approximately -inch) strip of ointment is usually
enough unless otherwise directed by your doctor. Gently close the eyes and keep them closed for 1
or 2 minutes to allow the medicine to come into contact with the infection.
To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface
(including the eye). After using idoxuridine eye ointment, wipe the tip of the ointment tube with
a clean tissue and keep the tube tightly closed.

Do not use this medicine more often or for a longer time than your doctor ordered. To do so may
cause problems in the eyes. If you have any questions about this, check with your doctor.

To help clear up your infection completely, keep using this medicine for the full time of treatment,
even though your symptoms may have disappeared. Do not miss any doses.

If your dose is different, do not change it unless your doctor tells you to do so.

The number of doses you use each day, the time allowed between doses, and the length of time you use the
medicine depend on the medical problem for which you are using idoxuridine.
