  • Absorption: Metabolized by the liver and lung enzymes.
  • Excretion: Primarily excreted in urine.
  • Contraindications: Avoid in women with hypersensitivity to carboprost, acute pelvic inflammatory disease, and specific cardiac, pulmonary, renal, or hepatic diseases. Use caution in those with asthma, hypotension/hypertension, anemia, jaundice, diabetes, epilepsy, or previous uterine surgery.
  • Adverse Reactions: Excessive doses can cause tetanic contractions, uterine rupture, hypertonus when used with oxytocin, nausea, vomiting, diarrhea, fever, chills, headaches, and changes in blood pressure.
  • Nursing Considerations: Store refrigerated, administer via deep intramuscular injection, rotate injection sites, monitor vital signs, and administer antiemetics as necessary.

Misoprostol (Cytotec)

  • Actions for Hypertonic Contractions: Place the patient in a side-lying position; provide oxygen and administer tocolytic drugs like terbutaline or magnesium sulfate if necessary.
  • Oxytocin Induction: Can begin at least 4 hours after the last dose of Misoprostol.
  • Precautions: Misoprostol is only FDA-approved for peptic ulcer treatment but is commonly used for labor induction and cervical ripening. The manufacturer will not seek additional approval. Contraindicated in women with previous cesarean or uterine surgery. Hospital pharmacy should prepare accurate 25-mcg doses.

Apresoline (Hydralazine)

  • Classification: Antihypertensive.
  • Action: Relaxes arterial smooth muscle leading to reduced blood pressure.
