Glyceryl trinitrate
Read all of this leaflet carefully before you start using this medicine because it contains important information for you.
Contents of the pack:
The Dermatrans patches contain the active ingredient glyceryl trinitrate, a vasodilator used in heart diseases, which belongs to a group of drugs called organic nitrates.
The Dermatrans patches are applied to the skin and then the active ingredient will pass continuously through your skin into your body.
Dermatrans is indicated for the prevention of angina attacks, either alone or in combination with other anti-anginal therapy.
Angina usually manifests as pain or pressure in the chest, although it can be felt in the neck or arm. The pain occurs when the heart is not sufficiently oxygenated. Dermatrans is not indicated for the treatment of acute attacks. For the treatment of acute attacks, you should use your usual sublingual or sublingual spray.
The Dermatrans patches are for external use only.

Warnings and precautions
Consult your doctor, pharmacist, or nurse before taking Dermatrans:
Using other medicines
The simultaneous administration of medicines for the treatment of erectile dysfunction (e.g., sildenafil or any other PDE-5 inhibitor) enhances the blood pressure-lowering effects of nitrates and should therefore be avoided (see also "Do not use Dermatrans").
Concomitant treatment with riociguat, a soluble guanylate cyclase stimulator, should be avoided, as its use in combination with nitrates can cause hypotension (see also "Do not use Dermatrans").
Concomitant treatment with
may enhance the blood pressure-lowering effects of Dermatrans.
Concomitant treatment with dihydroergotamine may reduce the effect of Dermatrans.
Non-steroidal anti-inflammatory drugs, except for acetylsalicylic acid, may decrease the therapeutic response to Dermatrans.
Tell your doctor or pharmacist if you are using, have recently used, or might use other medicines.
Fertility, pregnancy, and breastfeeding
Dermatrans should not be used during pregnancy, especially during the first three months, unless your doctor advises you to do so.
Due to limited information on the presence of glyceryl trinitrate in breast milk, the risk to the baby cannot be excluded. Your doctor will decide whether to discontinue breastfeeding or the use of Dermatrans.
No data are available on the effect of Dermatrans on human fertility.
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.
Driving and using machines
Especially at the start of treatment or in case of dose adjustment, Dermatrans may affect your ability to drive or use machines, as it may reduce your reaction time or rarely cause hypotension when standing up and dizziness, as well as exceptional cases of fainting after an overdose.
If you experience these effects, do not drive or use machines.
Follow exactly the administration instructions of this medicine indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.
The recommended dose is one Dermatrans patch once a day. You should apply the patch to your skin carefully and keep it on for 12-16 hours, then remove the patch and leave a patch-free period for the remaining 8-12 hours. You should change your Dermatrans patch according to the instructions given by your doctor. Your doctor will tell you how long to keep the patch on your skin and the duration of the patch-free interval.
Use in children and adolescents
Dermatrans should not be used in children and adolescents under 18 years of age.
How long to use Dermatrans
Treatment with Dermatrans can be continued for several years, however, your doctor should see you periodically to decide whether to continue treatment or change the therapeutic regimen.
How to apply the patch
You should apply the patch to clean, dry skin, avoiding areas with cuts, spots, or imperfections, or areas where you have just applied cream, a moisturizing product, or talcum powder. It is recommended to apply the Dermatrans transdermal patches to the skin of the chest (see Figure 1) or the upper outer arm, in areas without redness or irritation, and change the application sites. The suitable area can be shaved if necessary. Areas that form folds or are subject to friction during movement should be avoided.
Figure 1
Do not apply two consecutive patches to the same place.
Once the Dermatrans patch is removed from the pouch, it should be applied immediately to the skin, as follows:
(I) Open the pouch at the notch.
Do not use scissors (see Figure 2).
Figure 2
(II) Hold the patch with your thumb and index finger on the tab that will be removed
(see Figure 3).
Figure 3
(III) Remove the protective liner with the other hand
(see Figure 4). Do not touch the adhesive side of the patch, as it will not stick well.
Figure 4
(IV) Apply the open part of the patch to the skin and remove the remaining part of the protective liner. Press firmly for about 10 seconds on the entire surface of the patch. Pass your fingers over the edges of the patch again to ensure it is firmly stuck.
Wash your hands before and after applying Dermatrans.
To remove a patch, simply peel it off from the edge and gently pull the patch until it comes off. After use, fold the patch in half, with the adhesive side inward, and throw it away in a trash can where children cannot reach it.
What to do if the patch falls off
If Dermatrans is applied correctly, it is very unlikely that the patch will fall off. However, if the patch falls off, replace it with a new one and follow the usual periodic schedule with the next patch.
If you use more Dermatrans than you should
If you apply high doses of glyceryl trinitrate, you may experience a severe drop in blood pressure, increased heart rate, or collapse and fainting, as well as alteration in hemoglobin (methemoglobinemia).
If you or someone else applies too many patches at the same time, remove the patches carefully and wash the underlying skin carefully to reduce absorption. In case you experience a drop in blood pressure or collapse, it is recommended that you elevate your legs or, if necessary, apply compression bandages.
If you forget to change the patch
If you forget to change the patch at the corresponding time, you should change it as soon as possible and then follow your original periodic schedule, applying the next patch.
If you stop treatment with Dermatrans
When you stop treatment with Dermatrans, you may experience a recurrence of angina attacks.
If you have any further questions on the use of this product, ask your doctor, pharmacist, or nurse.
