Brand: PHENPRES LS Injection
Content: Phenylephrine Hydrochloride I.P. 50 mcg / ml
Company / Manufacturer: Neon Laboratories Ltd
Pack: 10 ml Vial
Category: Anti-hypotensive Agent / Vasopressor AgentProduct Description
PHENPRES LS Vial contains Phenylephrine Hydrochloride in a low-strength, ready-to-use parenteral format. It is widely used in operating rooms, critical care units, and emergency settings to manage or prevent sudden low blood pressure (hypotension) that occurs during spinal or general anesthesia. By delivering a precise, low-dose concentration of the active molecule, this sterile solution allows clinical teams to perform micro-adjustments to systemic blood pressure during delicate surgeries without requiring manual hospital dilution steps.Key Uses
- Management and rapid correction of low blood pressure resulting from spinal anesthesia during operations
- Immediate blood pressure support in circulatory shock or trauma-induced hypotensive states
- Intraoperative stabilization of blood pressure during specialized pediatric or adult surgical interventions
How It Works
Phenylephrine is a selective alpha-1 adrenergic receptor agonist. It works by targeted stimulation of the alpha receptors embedded in the vascular smooth muscles of peripheral blood vessels. This action triggers immediate vasoconstriction, which narrows the diameter of the arterioles. This narrowing systematically raises systemic vascular resistance, leading to a smooth, predictable increase in blood pressure while inducing a mild, physiological reduction in heart rate.Directions for Use
- Administer strictly via intravenous injection or targeted intravenous infusion routes
- Visually check the solution inside the multi-dose vial for any particles or tinting before extraction
- Use the exact pre-calculated low-dose volumes to avoid unintended systemic blood pressure spikes
- Must be handled and administered exclusively by a registered anesthesiologist or trained healthcare expert
