Levosimendan Eql Pharma (Levosimendan)

Levosimendan is used in the treatment of severe cardiac conditions where enhanced contractility and vasodilation are required.

• Acute decompensated heart failure: improves cardiac output and relieves symptoms of congestion.
• Cardiogenic shock: stabilizes hemodynamics and supports systemic circulation.
• Severe chronic heart failure (as bridge therapy): provides temporary inotropic support while definitive therapy is arranged.

• Levosimendan binds to cardiac troponin C, increasing its sensitivity to calcium and thereby augmenting myocardial contractility without raising intracellular calcium levels. Simultaneously, it opens ATP‑sensitive potassium channels in vascular smooth muscle, producing arterial and venous vasodilation. The drug’s effect is calcium‑independent, which limits the risk of arrhythmogenic calcium overload, and its vasodilatory action also contributes to decreased systemic vascular resistance.

Levosimendan may be associated with several adverse reactions, which are categorized by frequency and severity.

Common Side Effects

• Hypotension: drop in blood pressure, especially after rapid infusion.
• Headache: mild to moderate intensity during treatment.
• Nausea or vomiting: gastrointestinal discomfort reported in some patients.

Serious or Rare Side Effects

• Severe hypotension: profound blood pressure fall requiring intervention.
• Ventricular arrhythmias: potentially life‑threatening cardiac rhythm disturbances.
• Myocardial ischemia: chest pain or ECG changes indicating reduced coronary perfusion.
• Allergic reactions: rash, pruritus, or anaphylaxis in rare cases.

When using Levosimendan, clinicians should observe specific precautions to minimize risk.

• Renal impairment: monitor renal function and adjust therapy as needed.
• Hepatic impairment: use with caution; liver dysfunction may affect drug metabolism.
• Hypotension: assess baseline blood pressure and avoid rapid infusion rates.
• Concomitant vasodilators: increased risk of additive blood pressure lowering.
• Pregnancy and lactation: safety not established; avoid unless benefit outweighs risk.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Levosimendan can interact with other medicines, influencing its efficacy or safety.

Major Interactions (Avoid)

• Sodium nitroprusside: additive vasodilation may cause severe hypotension.
• Phosphodiesterase‑3 inhibitors (e.g., milrinone): combined inotropic effect can lead to excessive cardiovascular stimulation.
• Other calcium sensitizers: unknown synergistic effects, avoid co‑administration.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may blunt expected tachycardia response.
• ACE inhibitors or ARBs: additive blood pressure reduction requires monitoring.
• Diuretics: electrolyte disturbances may be amplified; monitor serum levels.
