Carnisure Inj

CARNISURE INJ

CARNISURE INJ is an injectable medication manufactured by Torrent Pharmaceuticals Ltd., primarily used to address carnitine deficiencies in the body.

Composition

The active ingredient in CARNISURE INJ is Levocarnitine, with each 5 ml ampoule typically containing 1 gram of Levocarnitine. Levocarnitine is an amino acid derivative crucial for mammalian energy metabolism, facilitating the transport of long-chain fatty acids into cellular mitochondria for energy production.

Uses

CARNISURE INJ is prescribed for the management of levocarnitine deficiency, which can arise from various causes:

• Primary Systemic Carnitine Deficiency: A congenital condition present from birth.
• Secondary Carnitine Deficiency: Occurring due to certain metabolic disorders (e.g., methylmalonic aciduria, propionic acidemia, glutaric aciduria, medium-chain fatty acyl dehydrogenase deficiency) that lead to the accumulation of abnormal and toxic metabolites.
• Carnitine Deficiency in Hemodialysis Patients: Used to prevent and treat carnitine deficiency in individuals with end-stage renal disease undergoing dialysis.

This medication helps to improve energy production, alleviate metabolic abnormalities, and can address symptoms such as muscle weakness, fatigue, and issues affecting the heart, liver, or brain.

Dosage and Administration

CARNISURE INJ is administered intravenously by a healthcare professional; it should not be self-administered. The dosage is determined by a doctor based on the patient's age, body weight, and medical condition.

• Adults: Typical dosage ranges from 50 mg/kg to 100 mg/kg per day, divided into multiple doses. The starting dose is usually 500 mg twice daily (total daily dose: 1000 mg), which can be increased up to a maximum of 3000 mg per day. A recommended dose of 20-40 mg/kg given as a slow 2-3 minute bolus injection or by infusion is also indicated.
• Elderly Patients (65 years and older): The starting dose may be lower, typically 250 mg twice a day (total daily dose: 500 mg).
• Children (2 years to 11 years): Starting dose is 20 mg/kg per day, divided into two doses, increasing up to a maximum of 60 mg/kg per day as needed.
• Infants (1 month to 23 months): Starting dose is 10 mg/kg per day, divided into two doses, increasing up to a maximum of 30 mg/kg per day as needed.

Side Effects

Common side effects may include:

• Vomiting, nausea, stomach pain, abdominal cramps, diarrhea.
• Headache.
• An abnormal fish-like body odour.
• Injection site reactions such as pain, swelling, and redness.

Serious, though rare, side effects warrant immediate medical attention:

• Signs of allergic reaction (difficulty swallowing or breathing, hives, swelling of the face, lips, tongue, or throat, rash).
• Unexplainable muscle pain, tenderness, or weakness, and dark brown urine (Rhabdomyolysis).
• Signs of increased calcium levels (increased thirst, frequent urination, nausea, vomiting, constipation, bone pain, confusion, and fatigue).
• Signs of high blood pressure (headache, dizziness, vision problems, shortness of breath), and palpitations.

Precautions

• Kidney Disease: Not recommended for use in patients with severely compromised renal function, particularly with high doses of oral formulations, due to the potential accumulation of toxic metabolites (trimethylamine and trimethylamine-N-oxide). The intravenous form is indicated for ESRD patients on hemodialysis.
• History of Fits: Use with caution in patients with a history of fits or seizures.
• Pregnancy and Breastfeeding: Should be used with caution; consult a doctor before use due to limited safety data.
• Drug Interactions: Inform your doctor about all prescription and non-prescription medicines, supplements, and herbal products being taken. Warfarin, when taken with CARNISURE INJ, may increase the time required for blood clot formation.
• Blood Glucose Monitoring: Regular monitoring of blood glucose levels may be necessary.
• Liver Disease: CARNISURE INJ is considered probably safe for use in patients with liver disease, and dose adjustment may not be needed.

Storage

CARNISURE INJ should be stored at a controlled room temperature, ideally below 25°C or below 30°C. It is recommended not to store it in the refrigerator. Keep the medicine out of reach of children and protect it from light.

Here are the most frequently asked questions about CARNISURE INJ by Torrent Pharmaceuticals Ltd.:

What is CARNISURE INJ used for?

CARNISURE INJ is primarily used to treat carnitine deficiency. This includes primary systemic carnitine deficiency, secondary carnitine deficiency resulting from inborn errors of metabolism (such as methyl malonic aciduria, propionic acidemia, glutaric aciduria, and medium-chain fatty acyl dehydrogenase deficiency), and carnitine deficiency in patients with end-stage renal disease who are undergoing dialysis. It helps improve energy production and alleviates metabolic abnormalities caused by low carnitine levels.

How does CARNISURE INJ work?

CARNISURE INJ contains Levocarnitine, which is an amino acid derivative. It works by increasing the levels of carnitine in the body. Carnitine plays a crucial role in transporting long-chain fatty acids into the mitochondria of cells, where they are oxidized to produce energy. By facilitating this process, it helps the body produce energy more efficiently and supports the normal functioning of internal organs, muscles, and nerves.

What is the usual dosage for CARNISURE INJ?

CARNISURE INJ is administered intravenously by a healthcare professional and should not be self-administered. For adults, the recommended intravenous dose is typically 20-40 mg/kg, given as a slow 2-3 minute bolus injection or by infusion. An adult starting dose might be around 500 mg twice a day, with the possibility to increase up to a maximum of 3000 mg per day, divided into two or three doses. For infants and children, the dosage is usually 50 to 100 mg/kg/day in divided doses, with a maximum of 3 grams per day, and is determined by the doctor based on the child's body weight and clinical response.

What are the possible side effects of CARNISURE INJ?

Common mild side effects may include nausea, vomiting, stomach pain or abdominal cramps, diarrhea, headache, and a peculiar "fishy" body odor. Reactions at the injection site such as pain, swelling, and redness can also occur. While generally mild and temporary, if these side effects persist or worsen, medical consultation is advised. Rarely, more serious side effects can occur, including allergic reactions (difficulty breathing, swelling), unexplained muscle pain with dark brown urine (rhabdomyolysis), increased calcium levels, high blood pressure, palpitations, decreased blood platelet count, anemia, bronchitis, seizures, and low blood sugar.

Is CARNISURE INJ safe during pregnancy or breastfeeding?

During pregnancy, CARNISURE INJ is generally considered safe if prescribed by a doctor. Animal studies have shown no or low adverse effects on the fetus, but there are limited well-controlled studies in pregnant women. Therefore, it should be used only if clearly needed after a thorough discussion with your doctor.

For breastfeeding mothers, CARNISURE INJ is probably safe to use if prescribed, as limited human data suggest it does not pose a significant risk to the baby. Levocarnitine is a normal component of human milk, but its supplementation in nursing mothers has not been specifically studied. It is advisable to consult your doctor before using this medicine while breastfeeding.

Can CARNISURE INJ be taken with other medications?

It is crucial to inform your doctor about all prescription, non-prescription, herbal, and supplement medications you are currently taking. CARNISURE INJ may interact with certain drugs. For example, it may increase the time required for blood clot formation when taken with warfarin. Concomitant use with valproic acid and sodium benzoate should generally be avoided. Your doctor should also be aware if you are taking medicines for elevated blood sugar levels.

What precautions should be taken with CARNISURE INJ?

CARNISURE INJ is not recommended for patients with a history of fits (seizures) or severely compromised renal (kidney) function, as it can lead to the accumulation of potentially toxic metabolites. Patients with any degree of kidney disease should use this medicine with caution, and dose adjustments may be necessary. Regular monitoring of blood glucose levels is also recommended during treatment. CARNISURE INJ should always be administered by a qualified healthcare professional; it is not for self-administration. Inform your doctor about any known allergies to the components of the injection.

What happens if a dose of CARNISURE INJ is missed?

Since CARNISURE INJ is typically administered in a clinical or hospital setting by a healthcare professional, the likelihood of missing a dose is very low. However, if a scheduled dose is missed, it is important to contact your doctor or pharmacist immediately to arrange for a new dosing schedule. Do not attempt to take a double dose to compensate for the missed one.

How should CARNISURE INJ be stored?

CARNISURE INJ vials should be stored in a cool and dry place, away from direct sunlight, at a controlled room temperature (typically between 10°C and 25°C or below 30°C). It should not be stored in the refrigerator or frozen. After mixing or dilution, the solution may be stored at room temperature for up to 24 hours. Any unused portion of an opened vial should be discarded. Always keep this medicine out of the reach and sight of children.
