Nalphin Injection 20 mg/ml contains Nalbuphine, a semi-synthetic opioid analgesic used for the management of moderate to severe pain. It is a potent parenteral formulation intended for intravenous (IV), intramuscular (IM), or subcutaneous (SC) administration, providing rapid and effective pain relief in hospital and clinical settings. Nalphin is a mixed agonist-antagonist opioid, offering analgesic benefits while minimizing certain opioid-related risks such as respiratory depression and dependence.

Nalbuphine works by selectively activating kappa-opioid receptors in the central nervous system, producing analgesia, while acting as a partial antagonist at mu-opioid receptors. This dual mechanism provides effective pain control with a reduced potential for euphoria and abuse. The high concentration of 20 mg/ml allows precise dosing, making it ideal for acute pain management, post-operative analgesia, and labor pain relief.

Indications

Nalphin Injection 20 mg/ml is indicated for:

• Management of moderate to severe acute pain, including post-operative and trauma-related pain

• Pain relief during labor and delivery

• Analgesia in patients requiring parenteral opioid therapy in clinical or hospital settings

It is important to note that Nalphin is not intended for long-term pain management or for use in outpatient self-administration without medical supervision.

Dosage and Administration

The dosage of Nalphin Injection depends on the severity of pain, route of administration, and patient response:

• Adults: 10–20 mg IV, IM, or SC every 3–6 hours as needed for pain. IV injections should be administered slowly to reduce the risk of adverse effects.

• Elderly or debilitated patients: Lower doses or extended dosing intervals may be necessary.

Doses should be titrated by healthcare professionals to achieve optimal analgesia while minimizing potential side effects. Continuous monitoring is recommended when administering IV injections to assess for sedation, respiratory status, and blood pressure changes.

Precautions and Warnings

• Use cautiously in patients with respiratory disorders such as asthma or chronic obstructive pulmonary disease, as opioids may cause respiratory depression.

• Avoid in patients with head injury, increased intracranial pressure, or impaired consciousness.

• Dose adjustment may be required for patients with liver or kidney impairment.

• Concomitant use with CNS depressants, sedatives, or alcohol may enhance sedative or respiratory effects.

• Not recommended during pregnancy or lactation unless clearly necessary and under medical supervision.

• Monitor for potential dependence or abuse, though risk is lower than with pure mu-opioid agonists.
