Pentacarinat 300 mg powder for injectable solution is a powder for administration via intramuscular or intravenous routes.

The active ingredient of Pentacarinat is pentamidine isethionate, which is an antiprotozoal agent that acts lethally against microorganismsPneumocystis jirovecii(previously known asPneumocystis carinii),Trypanosoma gambienseandLeishmania, possibly inhibiting protein synthesis.

It is indicated for the treatment of:

• pneumonia caused byPneumocystis jirovecii(previously known asPneumocystis carinii),
• cutaneous leishmaniasis,
• early stage of African sleeping sickness caused byTrypanosoma gambiense.

No use Pentacarinat

• If you are allergic to pentamidine isethionate or any of the other components of this medication (listed in section 6).

Warnings and Precautions

Consult your doctor, pharmacist, or nurse before starting to use Pentacarinat:

• If your liver and/or kidney function is impaired, you have high or low blood pressure, elevated or low blood sugar levels, or a decreased number of white blood cells, red blood cells, or platelets in your blood.
• Due to the possibility of severe adverse reactions, sometimes with fatal outcome, such as low blood pressure (hypotension), low blood sugar (hypoglycemia), acute pancreatitis, and cardiac arrhythmias.
• After a dose of Pentacarinat, your blood pressure may drop to very low levels suddenly. Therefore, your doctor will monitor your blood pressure before and during administration, as well as at regular intervals during treatment. The medication will be administered in a lying down position, face up.
• Due to the possibility of QT interval prolongation. Cases of severe cardiac arrhythmias (sometimes with fatal outcome) caused by this effect, such as "Torsades de pointes", have been reported. Therefore, your doctor will consider the possibility of performing an electrocardiogram before starting treatment. Therefore, special care should be taken when administering Pentacarinat if you have conditions that increase the risk of arrhythmias, including patients with long QT syndrome, heart disease, a history of arrhythmias, low potassium and/or low magnesium levels in the blood, bradycardia (slow heart rate), or during concomitant administration with medications that prolong the QT interval (see "Pentacarinat use with other medications").
• Due to the possible alteration of certain parameters in blood, urine, or liver function. Laboratory tests should be performed, before, during, and after treatment:

• Daily during treatment: blood urea, nitrogen, and creatinine, complete blood count and platelet count, urine analysis, and serum electrolyte levels.
• Fasting blood sugar levels, daily during treatment, and at regular intervals after treatment. Hyperglycemia and diabetes mellitus, with or without previous hypoglycemia, may appear even several months after treatment is completed.
• Calcium levels, weekly, and magnesium levels, twice a week.
• Electrocardiogram at regular intervals.
• Liver function tests, including bilirubin, alkaline phosphatase, aspartate aminotransferase (AST/SGOT), and alanine aminotransferase (ALT/SGPT). If baseline values are normal and remain normal during treatment, controls will be performed weekly.

If baseline liver function test values are elevated, or become elevated during treatment, you will be monitored weekly, unless you are being treated with medications that can damage the liver, in which case you will be monitored every 3-5 days.

Pentacarinat use with other medications

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

Caution is advised if you are using Pentacarinat at the same time as:

• Medications known to prolong the QT interval, including:

• Certain medications for arrhythmia treatment (such as quinidine, disopyramide, and procainamide or amiodarone and sotalol).
• Medications for depression (tricyclic antidepressants or certain tetracyclic antidepressants such as maprotiline).
• Certain medications for psychosis treatment (such as phenothiazines and pimozide).
• Certain medications for allergy treatment (such as astemizol and terfenadine).
• Antibiotics (such as quinolones, intravenous erythromycin).
• Medications for malaria treatment (such as halofantrine, mefloquine).
• Bepridil (for angina pectoris treatment).
• Cisapride (medication to improve gastric motility).

• Foscarnet (medication used to treat certain viral infections), due to the risk of decreased calcium levels.

Pregnancy and lactation

If you are pregnant or breastfeeding, or think you may be pregnant, consult your doctor or pharmacist before using this medication.

Pregnancy:

Do not use Pentacarinat if you are pregnant, as the safety of Pentacarinat use during pregnancy has not been studied.

Lactation:

Do not recommend using Pentacarinat if you are breastfeeding.

Driving and operating machinery

The influence of Pentacarinat on the ability to drive or operate machinery is unknown.

Cases of dizziness have been reported, so you should be aware when driving or operating machinery.

The recommended dose for:

• Pneumocystis jiroveci pneumonia: 4 mg/kg of body weight of pentamidine isethionate, once a day, for at least 14 days, preferably by slow intravenous infusion. Intramuscular administration is not recommended in these cases. IV is the preferred route of administration for the treatment of Pneumocystis jiroveci pneumonia.
• Cutaneous leishmaniasis: 4 mg/kg of body weight of pentamidine isethionate, three doses on alternate days, by intramuscular or intravenous injection.
• Trypanosomiasis: 4 mg/kg of body weight of pentamidine isethionate, once a day, or every two days, until a total of 7-10 doses. Either intramuscular or intravenous administration can be used.

• In Pneumocystis jiroveci pneumonia:

• In cases with vital risk, administer 4 mg/kg of body weight once a day for 7-10 days, and then 4 mg/kg of body weight on alternate days until completing the cycle of at least 14 doses.
• In less severe cases: administer 4 mg/kg of body weight on alternate days until completing the cycle of at least 14 doses.

Intramuscular administration is not recommended in these cases. IV is the route of administration for the treatment of Pneumocystis jiroveci pneumonia.

• In cases of leishmaniasis and trypanosomiasis, dose reduction is not necessary.

No special dose recommendations exist for elderly patients and those with altered liver function.

Pentacarinat is administered by deep intramuscular injection or slow intravenous infusion (see "Instructions for correct administration of the preparation by healthcare professionals").

It must be administered always with the patient in a horizontal position, both for deep intramuscular injection and for slow intravenous infusion.

The dose to be administered must be reconstituted in water for injectable preparations (see "Instructions for correct administration of the preparation by healthcare professionals").

Your doctor will indicate the duration of your treatment with Pentacarinat. Do not discontinue your treatment before, as it must continue until he considers it necessary.

If you use more Pentacarinat than you should

Consult your doctor immediately. Cardiac rhythm alterations, including the so-called "Torsade de Pointes", have been reported after pentamidine isethionate overdose.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicological Information Service, phone 91 562 04 20, indicating the medication and the amount administered or ingested.

If you forgot to use Pentacarinat

No double dose will be administered to compensate for the missed doses.

INSTRUCTIONS FOR THE CORRECT ADMINISTRATION OF THE PREPARATION BY HEALTH PROFESSIONALS

The pentamidine isethionate powder must be reconstituted with water for injection (3 ml of water for injection). For intravenous administration, the required dose of pentamidine isethionate must be diluted, after reconstitution, in 50-250 ml of glucose solution (5 %) for infusion or in 150-300 ml of sodium chloride 0.9 %.

For the initial reconstitution of the pentamidine isethionate solution, saline solutions should not be used as they may cause precipitation of the medication. The resulting solution from reconstitution should not be mixed with other injectable solutions except glucose solution (intravenous infusion) or sodium chloride 0.9 %.
