Pitofenone is an antispasmodic compound commonly used in combination with other agents like fenpiverinium and metamizole for the treatment of smooth muscle spasms, particularly in the gastrointestinal and urogenital systems. It works by directly relaxing smooth muscle fibers, helping relieve pain and discomfort caused by muscle spasms.
It is frequently indicated for:
∙ Renal colic
∙ Biliary colic
∙ Intestinal cramps
∙ Gynecological pain (e.g., dysmenorrhea)
Pitofenone is available in both oral and injectable dosage forms, especially in fixed-dose combinations in Central and Eastern Europe.
Parent: Pitofenone/ Pitofenone Hydrochloride
Impurities in Pitofenone can originate from its chemical synthesis, degradation during shelf life, or excipient interactions. Regulatory bodies such as ICH and pharmacopeias require the identification and qualification of these impurities to ensure safety and efficacy.

Analytical Techniques for Impurity Detection
Pitofenone is used as an antispasmodic to relieve pain associated with smooth muscle spasms, particularly in the stomach, intestines, bile ducts, urinary tract, and uterus.
It is most commonly used in fixed-dose combinations with other agents like fenpiverinium and metamizole to enhance its analgesic and antispasmodic effects.
Use during pregnancy is generally not recommended unless clearly necessary and prescribed by a physician.
It should be stored in a cool, dry place away from light and moisture to minimize degradation and impurity formation.
