Magnesium Sulfate 50% Injection 1 Gram Per 2 mL Single-Dose Vials x 25/Tray by Fresenius (Rx)

Magnesium Sulfate 50% Injection is primarily used in the treatment of eclampsia and severe pre-eclampsia in pregnant women, acting as an anticonvulsant to prevent seizures. It is also administered to correct magnesium deficiency and manage certain cardiac arrhythmias. In critical care, it helps alleviate symptoms of acute asthma and preterm labor. By relaxing muscles and nerves, this injection plays a crucial role in emergency and obstetric contexts, stabilizing patient conditions.

Fresenius USA presents Magnesium Sulfate 50% Injection, a crucial therapeutic solution designed for managing and treating acute magnesium deficiencies and various medical conditions requiring magnesium supplementation. Each single-dose vial delivers 1 gram of magnesium sulfate in a highly concentrated 50% formulation (2 mL per vial), tailored for rapid intervention in critical care scenarios. Packaged in trays containing 25 vials, this product ensures that healthcare providers have immediate access to essential magnesium therapy when it is most needed.

Details and Features:

Concentration and Dosage: Each vial contains 1 gram of magnesium sulfate (500 mg/mL), enabling precise control and rapid modulation of serum magnesium levels during acute treatment.
Packaging: Offered in single-dose vials, organized into trays of 25, optimizing both storage efficiency and accessibility in high-demand clinical settings.
Administration Route: Administered intravenously or intramuscularly, allowing for flexible application depending on the onset speed required for the condition being treated.
Indications: Recommended for the treatment of acute magnesium deficiency, eclampsia and pre-eclampsia, prevention and control of seizures, as well as for torsades de pointes and other acute arrhythmias linked to hypomagnesemia.

Mechanism of Action:

Magnesium sulfate acts as a potent electrolyte replenisher and anticonvulsant. In the body, magnesium is essential for enzyme activity, neuromuscular transmission, and cardiovascular function. As a CNS depressant, magnesium sulfate stabilizes neuromuscular excitation and conduction, effectively managing seizures and providing muscle relaxation in eclamptic settings. Its antiarrhythmic properties help rectify cardiac arrhythmias by modulating the distribution and flux of key electrolyte ions during cardiac action potential phases.

Warnings:

• Cardiovascular Risks: Potential for serious cardiovascular effects, such as severe hypotension, bradycardia, and heart block, especially with rapid administration or overdose. Cardiac monitoring is strongly recommended.
  
• Respiratory Depression: High doses can lead to respiratory paralysis. Therefore, assess respiratory function rigorously when administering magnesium sulfate.
  
• Hypermagnesemia: Symptoms like flushing, sweating, low blood pressure, and central nervous system depression could indicate toxicity, necessitating immediate adjustment or cessation of administration.
  
• Renal Impairment: Use cautiously in patients with renal dysfunction, as magnesium is primarily excreted by the kidneys, increasing the risk of accumulation and toxicity.

Side Effects:

• Common Adverse Effects: Sensations of warmth or flushing, sweating, and thirst.
  
• Severe Adverse Effects: Dysrhythmias, hypotension, and central nervous system depression, including confusion or lethargy.
  
• Injection Site Reactions: Localized discomfort or irritation at the injection site, particularly with intramuscular administration.

Clinical Considerations:

• Monitoring: Continuous monitoring of cardiovascular, respiratory, and neuromuscular function is essential during treatment. Serum magnesium levels should guide dosage adjustments.
  
• Patient Assessment: Comprehensive evaluation of renal function, pre-existing conditions, and concomitant medications is crucial before initiating therapy.
  
• Emergency Preparedness: Facilities should have calcium gluconate on hand to counteract potential magnesium sulfate overdose, providing immediate relief for severe cardiac or respiratory depression.

Magnesium Sulfate 50% Injection by Fresenius USA is designed for healthcare professionals in critical and acute care environments. This versatile product empowers them with the precise tools necessary for emergent clinical interventions that hinge on electrolyte balance and seizure management. Always refer to and adhere to the detailed prescribing information to ensure optimal patient outcomes.
