Felypressin is primarily used in the medical and dental fields for its vasoconstrictive properties. It is commonly added to local anesthetic solutions to prolong their effect by reducing blood flow to the area, thereby slowing the absorption of the anesthetic. This makes it particularly useful in dental procedures, where it helps to minimize bleeding and enhance the duration of pain relief. Additionally, its vasoconstrictive action is beneficial in controlling minor bleeding during minor surgical interventions. Felypressin is often preferred over other vasoconstrictors like epinephrine in patients with certain cardiovascular conditions, as it has a milder impact on the heart.
