phenylephrine + heparin

Phenylephrine + heparin is a combination of two active pharmaceutical ingredients used together, typically in hospital or procedural settings. Phenylephrine is an alpha-1 adrenergic receptor agonist that acts as a vasoconstrictor, increasing blood pressure and reducing swelling by constricting blood vessels[3][8]. Heparin is an anticoagulant that prevents the formation and extension of blood clots by potentiating the activity of antithrombin III, thereby inhibiting thrombin and factor Xa[6]. This combination may be used in clinical scenarios where both vasoconstriction (to maintain vascular tone or reduce local bleeding) and anticoagulation (to prevent catheter-related thrombosis or maintain line patency) are desired. There are no widely recognized brand names for this specific combination; it may be prepared for specific procedural use.
