Adenosine Injection 3mg/ml (2ml amp) is a fast-acting cardiovascular medication primarily used to treat certain types of irregular heart rhythms, such as paroxysmal supraventricular tachycardia (PSVT). It works by slowing electrical conduction in the heart, helping to restore a normal rhythm. This injection is often administered in emergency settings due to its rapid onset and short duration of action.



The formulation comes in a convenient 2ml ampoule, with each milliliter containing 3mg of adenosine. This concentration allows for precise dosing, which is critical given the drug's potent effects. Healthcare providers typically administer it via rapid intravenous injection, often followed by a saline flush to ensure proper delivery into the bloodstream.




  • Rapid Action: Adenosine takes effect within seconds, making it ideal for acute arrhythmia management.

  • Short Half-Life: Its effects last only a few minutes, minimizing prolonged side effects.

  • Diagnostic Use: Helps differentiate between different types of supraventricular tachycardias.

  • Well-Tolerated: Though side effects like flushing or shortness of breath may occur, they are usually transient.



Due to its potency, Adenosine Injection should only be used under medical supervision. Patients with certain conditions, such as asthma or severe heart block, may require alternative treatments. Always ensure proper storage at controlled room temperature to maintain efficacy.



This medication is a staple in emergency medicine and cardiology, valued for its ability to quickly stabilize heart rhythms with a predictable safety profile when used correctly.

Adenosine Injection 3mg/ml (2ml amp) is a medication used primarily in the management of certain heart rhythm disorders, such as paroxysmal supraventricular tachycardia (PSVT). It works by slowing electrical conduction in the heart, helping to restore a normal rhythm. Below are detailed instructions for its proper use.




  1. Preparation: Ensure the patient is in a monitored environment, such as a hospital or clinic, where cardiac monitoring and resuscitation equipment are readily available. Adenosine is administered intravenously and requires immediate access to emergency support in case of adverse reactions.

  2. Dosage: The usual adult dose for PSVT is 6 mg administered as a rapid intravenous bolus over 1-3 seconds. If the arrhythmia persists after 1-2 minutes, a second dose of 12 mg may be given. The maximum single dose should not exceed 12 mg.

  3. Administration: Use a large vein, such as the antecubital fossa, for injection to minimize the risk of irritation. Administer the injection as a rapid bolus, followed immediately by a saline flush (20 ml) to ensure the medication reaches the systemic circulation quickly.

  4. Monitoring: Continuously monitor the patient’s ECG, heart rate, and blood pressure during and after administration. Adenosine has a very short half-life (less than 10 seconds), but its effects may last longer in some patients.

  5. Side Effects: Be aware of potential side effects, including flushing, chest pain, shortness of breath, and transient arrhythmias. These are usually brief but may require intervention in rare cases.

  6. Contraindications: Do not use Adenosine in patients with known hypersensitivity to the drug, second- or third-degree AV block (without a functioning pacemaker), or sinus node disease. Use with caution in patients with asthma or COPD due to the risk of bronchospasm.

  7. Storage: Store the ampoules at room temperature (20-25°C) and protect them from light. Do not use the solution if it appears discolored or contains particles.



Always follow the guidance of a healthcare professional when administering Adenosine Injection. Proper training and adherence to protocols are essential to ensure patient safety and effective treatment outcomes.
