1. What Dermatrans is and what it is used for

The Dermatrans patches contain the active ingredient glyceryl trinitrate, a vasodilator used in cardiac 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 tablet or spray.

The Dermatrans patches are for external use only.

2. What you need to know before using Dermatrans

Do not useDermatrans:

• if you are allergic to the active ingredient or to any of the other components of this medication (listed in section 6).
• if you have or have recently had a shock associated with very low blood pressure;
• if you suffer from headaches (cephalalgias), vomiting, or convulsions associated with increased intracranial pressure, including those caused by a head injury;
• if you suffer from cardiac insufficiency due to an obstruction, such as in the presence of aortic or mitral stenosis, or from a fibrotic thickening of the thin membrane surrounding the heart (constrictive pericarditis);
• if you are taking medications for the treatment of erectile dysfunction (e.g., sildenafil or any other PDE-5 inhibitor). Nitrates should not be administered to patients treated with sildenafil or any other medication used to treat erectile dysfunction. Patients who are currently receiving nitrates should not take sildenafil or any other medication for the treatment of erectile dysfunction. The combination of a nitrate with sildenafil or any other PDE-5 inhibitor can cause a profound and sudden drop in blood pressure, which can lead to fainting, loss of consciousness, or even a heart attack (see also "Do not use Dermatrans");
• if you are taking medications that contain riociguat, a soluble guanylate cyclase stimulator.
• if you have a severe drop in blood pressure (maximum arterial blood pressure of 90 mm Hg);
• if you suffer from a severe decrease in blood volume in your body due to significant blood loss or loss of other body fluids (severe hypovolemia);
• if you have severe anemia;
• if you have toxic fluid retention in the lungs (toxic pulmonary edema).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before taking Dermatrans:

• if you withdraw treatment. The withdrawal of treatment with Dermatrans should be gradual, by substituting with decreasing doses of long-acting oral nitrates;
• if you are going to undergo a magnetic resonance imaging scan, electrical stimulation of your heart to restore a normal heart rhythm (defibrillation or cardioversion), and before a heat treatment (diathermy), you should remove the Dermatrans patch before undergoing these treatments.

• if you have or have recently had a heart attack (myocardial infarction) or if you develop rapidly worsening symptoms of cardiac insufficiency (acute cardiac insufficiency) such as difficulty breathing, feeling very tired, or swelling of the legs. Your doctor may ask you to undergo laboratory tests to check your cardiovascular function.
• if you have a severe drop in blood pressure or if you experience a collapse or shock while being treated with Dermatrans, the patch should be removed;
• if you experience chest pain (acute angina attacks) or if your heart is not getting enough blood flow and oxygen (unstable angina) or in case of a heart attack (myocardial infarction). Dermatrans should not be used as immediate treatment for these conditions.
• if you experience severe headache or abnormally low blood pressure (hypotension). This can occur if the initial dose is too high. It is recommended to gradually increase the dose until the optimal effect is achieved;
• if you are taking other nitrates or sublingual glyceryl trinitrate, as your body may develop resistance to the effects of these substances after repeated exposure (cross-tolerance);
• if you have or have had abnormally low blood pressure induced by glyceryl trinitrate. In this case, you may experience a low heart rate (paradoxical bradycardia) and increased angina;
• if you suffer from optic nerve disease (angle-closure glaucoma);
• if you have insufficient oxygenation of the blood (hypoxemia) due to severe anemia or lung disease or reduced blood flow to your heart (ischemic cardiac insufficiency).

• Patient with these medical conditions often suffer from a ventilation/perfusion imbalance, which is an index of respiratory function. In these patients, glyceryl trinitrate could worsen the ventilation/perfusion imbalance and cause further decreased blood oxygenation;

• if the angina is caused by thickening of the heart (hypertrophic cardiomyopathy). Nitrates can worsen this type of angina;
• if you experience an increase in the frequency of angina attacks during patch-free periods. It is possible that your doctor may want to evaluate the possibility of additional anti-anginal therapy.
• If you experience skin sensitization (itching, burning, inflammation), treatment should be discontinued and your doctor consulted.

Use of other medications

The simultaneous administration of medications 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").

Simultaneous treatment with riociguat, a soluble guanylate cyclase stimulator, should be avoided, as its concomitant use can cause hypotension (see also "Do not use Dermatrans").

Simultaneous treatment with

• medications used to lower high blood pressure, such as calcium antagonists, ACE inhibitors (for the treatment of congestive heart failure), beta-blockers (used to manage cardiac arrhythmias), diuretics (to increase water elimination from the body), and other antihypertensives,
• tricyclic antidepressants (medications for the treatment of depressive disorders),
• neuroleptics (medications used to treat psychosis), and
• major tranquilizers (sedatives),
• as well as alcohol consumption and the combination of amifostine (a cytoprotective medication in chemotherapy and radiotherapy) and
• acetylsalicylic acid (an NSAID),

may enhance the blood pressure-lowering effects of Dermatrans.

Simultaneous treatment with dihydroergotamine may reduce the effect of Dermatrans.

Non-steroidal anti-inflammatory medications, except for acetylsalicylic acid, may decrease the therapeutic response to Dermatrans.

Inform your doctor or pharmacist if you are using, have recently used, or may need to use other medications.

Fertility, pregnancy, and lactation

Dermatrans should not be used during pregnancy, especially during the first three months, unless prescribed by your doctor.

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 interrupt 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 medication.

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 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, you should not drive or use machines.

3. How to use Dermatrans

Follow the administration instructions for this medication exactly as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

The recommended dose is one Dermatrans patch per 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 indicate how long you should 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 maintained 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

The patch should be applied to clean, dry skin, avoiding application over cuts, spots, or imperfections or over an area where cream, a moisturizing product, or talc has been applied. 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 to 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 side of the patch to the skin and remove the remaining 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 it 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 of hypotension or collapse, it is recommended to elevate the 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 interrupt treatment with Dermatrans

When you stop treatment with Dermatrans, you may experience a recurrence of angina attacks.

If you have any other doubts about the use of this product, ask your doctor, pharmacist, or nurse.
