Tericin IV Injection

Uses of Tericin IV Injection

• Severe Fungal Infections

How does Tericin IV Injection work?

Tericin IV Injection binds to ergosterol (steroid present on the cell membranes of fungi) which leads to the formation of pores and ion leakage on the cell membrane resulting in fungal cell death thus treating invasive fungal infections in affected individuals.

Side Effects of Tericin IV Injection

• Injection site reactions (pain, swelling, redness)
• Nausea
• Vomiting
• Chills
• Headache
• Anemia (low number of red blood cells)
• Decreased potassium level in the blood
• Abnormal liver function tests
• Decreased magnesium level in blood
• Diarrhea
• Decreased appetite
• Hypotension (low blood pressure)
• Skin rash
• Nephrocalcinosis
• Increased creatinine level in blood
• Abnormal renal function tests
• Renal tubular acidosis

Quick Suggestions:

• It is usually given as an injection over 1-2 hours under the supervision of a medical professional.
• Tericin IV Injection can cause rash, chills, headache, and tiredness during the initial days of the treatment, but these may fade away with time.
• Your doctor may ask you for regular blood tests to monitor your blood sugar, potassium, magnesium, and kidney function.
• Inform your doctor immediately if you notice pain or blood upon urination, swelling of the face, and trouble breathing.
• Inform your doctor if you are pregnant, planning pregnancy, or breastfeeding.

Indication of Tericin IV Injection

• Treats invasive fungal infections in patients who are resistant/intolerant to conventional Amphotericin B therapy

Pharmacology

Amphotericin B is a polyene antifungal antibiotic that works by binding to ergosterol in the cell membrane of fungi. This alters the permeability of the membrane, causing leakage of cell components and leading to fungal cell death. It is effective against various fungal species, including Candida, Aspergillus, Cryptococcus, and others mentioned in the provided list.

Dosage & Administration of Tericin IV Injection

Dosage regimens for amphotericin B (conventional) for different routes of administration and indications are as follows:

1. Oral Candidiasis (PO):

• Each lozenge contains 10 mg of amphotericin B.
• Suck 1 lozenge four times a day. If necessary, the dose can be increased up to 8 lozenges per day.

1. Systemic Fungal Infections (IV):

• Test Dose: Administer a one-time IV dose of 1 mg infused over 20-30 minutes.
• Loading Dose: Administer a loading dose of 0.25-0.5 mg per kilogram of body weight infused over 2-6 hours.
• Maintenance Dose: Administer a maintenance dose of 0.25-1 mg per kilogram of body weight once daily (day) or up to 1.5 mg per kilogram of body weight once every other day (EOD). The maintenance dose can be gradually increased by 0.25 mg increments per day.

Administration:

• Increased toxicity may occur when amphotericin B is used with flucytosine.
• Drug-induced renal toxicity can be enhanced in the presence of other nephrotoxic medications.
• Amphotericin B may antagonize the effects of azole antifungals.
• Potentially fatal interactions: Amphotericin B can potentiate potassium loss caused by corticosteroids. It should be avoided with diuretics. It can enhance digitalis toxicity and the effects of neuromuscular blockers.

Additional Considerations:

• Adjustments in dosage may be necessary for patients with renal or hepatic impairment. Close monitoring of renal and liver function is important.
• In pregnant patients, the risks and benefits of using amphotericin B should be carefully considered.
• The excretion of amphotericin B in breast milk is unknown. Due to the potential for serious adverse reactions in breastfed infants, a decision should be made whether to discontinue nursing or the drug, taking into account its importance to the mother.

Tericin IV Injection will be given to you only by a doctor or a nurse into a vein as an intravenous infusion. Your doctor will decide the correct dose and duration for you depending on your age, body weight, and disease condition.

Interaction

Nephrotoxic drugs: These are medications that can potentially cause kidney damage. Examples include aminoglycosides (e.g., gentamicin, tobramycin) and cisplatin. It is important to disclose the use of these drugs to your doctor, as combining them with Tericin IV Injection may increase the risk of kidney problems.

Zidovudine: This medication is used in the treatment of HIV. It is essential to inform your doctor if you are taking zidovudine, as there may be interactions between zidovudine and Tericin IV Injection. Your doctor will evaluate the potential risks and benefits of combining these medications.

Cyclosporin: Cyclosporin is used to prevent rejection of transplanted organs. If you are taking cyclosporin, it is important to discuss this with your doctor before receiving Tericin IV Injection. There may be interactions between these medications, and your doctor will monitor you closely for any potential adverse effects.

Contraindications

You are allergic to netilmicin or other aminoglycosides or any of the other ingredients of Netmicin Injection.

Pregnancy & Lactation

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.

It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.

Precautions & Warnings

• Allergies: Inform your doctor or pharmacist if you have any allergies to amphotericin B or any other substances. This medication may contain inactive ingredients that could cause allergic reactions or other complications. Discuss your allergies with your pharmacist for further information.
• Medical history: Share your complete medical history with your doctor or pharmacist, especially if you have a history of white blood cell (leukocyte) transfusions, heart disease (such as irregular heartbeat or congestive heart failure), liver disease, or kidney disease. These conditions may influence the use and dosage adjustments of amphotericin B.
• Pregnancy: During pregnancy, the use of amphotericin B should only be considered if the potential benefits outweigh the risks. It is important to have a discussion with your doctor regarding the risks and benefits of using the medication during pregnancy.
• Breastfeeding: It is unknown whether amphotericin B passes into breast milk. Consult your doctor before breastfeeding while using this medication to assess the potential risks and benefits.
