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. 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. 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.
