Palnox Injection (Palonosetron) 0.25mg is a prescription medicine primarily used to prevent nausea and vomiting caused by cancer chemotherapy and surgery. This medicine belongs to a specialized group of antiemetic drugs that work by blocking certain signals in the brain responsible for triggering nausea and vomiting.
Palnox Injection (Palonosetron) 0.25mg is classified under Prescription Medicines, Antiemetic Drugs, Oncology Supportive Care, and Injectable Therapies. It contains Palonosetron, which works by blocking serotonin (5-HT3) receptors involved in nausea and vomiting reflexes.
In some markets, the original brand Aloxi is widely used, while Palnox is available as a local generic option providing similar therapeutic benefits when prescribed by a qualified healthcare professional.
What Is Aloxi (Palonosetron)?
Aloxi is the original brand name for Palonosetron, an injectable medication widely used to prevent chemotherapy-induced and postoperative nausea and vomiting.
Palonosetron belongs to a class of medicines known as 5-HT3 receptor antagonists. These medicines help control nausea by blocking serotonin signals in the nervous system.
Generic versions such as Palnox Injection 0.25mg contain the same active compound and may be used depending on physician recommendation and regional availability.
Drug Class and Mechanism of Action
Palonosetron is classified as a selective serotonin (5-HT3) receptor antagonist with strong antiemetic properties.
How Palonosetron Works
It works in several ways:
- Blocks serotonin receptors in the brain and gut
- Prevents activation of the vomiting center
- Provides long-lasting control of nausea and vomiting
Through these mechanisms, Palonosetron helps prevent both acute and delayed nausea caused by chemotherapy.
How Aloxi Works in the Body
Chemotherapy and surgery can release serotonin, which triggers nausea and vomiting. Palonosetron blocks this pathway effectively.
Key Actions of Palonosetron
- Inhibits serotonin binding in the gastrointestinal tract
- Blocks signals to the brain’s vomiting center
- Provides prolonged anti-nausea effect (up to 72 hours)
Generic versions such as Palnox deliver the same active compound for effective nausea prevention when used appropriately.
