Pharmacology

đŸ”Ŧ

Mechanism of Action

Leuprolide acetate is a synthetic nonapeptide analog of naturally occurring gonadotropin-releasing hormone (GnRH). It acts as a potent inhibitor of gonadotropin secretion when given continuously. Initially, it causes a transient increase in luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels (a 'flare' effect), leading to a temporary increase in gonadal steroid production. However, continuous administration of leuprolide results in desensitization and downregulation of pituitary GnRH receptors, leading to a profound suppression of LH and FSH secretion. This, in turn, suppresses ovarian and testicular steroidogenesis, effectively reducing sex hormone levels to prepubertal or castrate levels. In Central Precocious Puberty (CPP), this suppression prevents further progression of puberty.

Precautions & Cautions

It is essential to inform all of your child's healthcare providers, including doctors, nurses, pharmacists, and dentists, that your child is taking this medication. Regular blood tests will be necessary, as directed by the doctor, to monitor your child's condition. Be sure to discuss any concerns or questions with the doctor.

This medication may interfere with certain laboratory tests, so it is crucial to notify all healthcare providers and laboratory personnel that your child is taking this drug.

During the initial few weeks of treatment, this medication may cause an increase in certain hormone levels in your child's body. As a result, signs of puberty, such as vaginal bleeding or spotting, may occur or worsen before improving. If your child experiences any new symptoms or if puberty signs persist after 2 months of treatment, notify the doctor.

In some cases, this medication may affect growth in children and teenagers. To monitor this potential effect, regular growth checks may be necessary. Discuss this with the doctor to determine the best course of action.

For children of childbearing age, a pregnancy test will be required before starting this medication to confirm that your child is not pregnant.

This medication may temporarily affect fertility during treatment, which could lead to difficulty conceiving. However, fertility typically returns to normal once the medication is discontinued. If you have concerns about this potential effect, consult with the doctor.

If your child is sexually active or may become sexually active:

If your child is using birth control, it is recommended to use a non-hormonal method, such as condoms, to prevent pregnancy while taking this medication.

If your child is pregnant or breastfeeding:

If your child becomes pregnant while taking this medication, it may harm the unborn baby. Immediately contact the doctor if your child is pregnant or suspects they may be pregnant.
* If your child is breastfeeding, inform the doctor, as they will need to discuss potential risks to the baby and determine the best course of action.

Timing: Prior to initiation of therapy.

📊

Routine Monitoring

Clinical Signs of Puberty

Frequency: Every 3-6 months or at each visit

Target: Regression or stabilization of pubertal signs

Action Threshold: Progression of pubertal signs may indicate inadequate suppression or non-adherence.

Height and Weight

Frequency: Every 3-6 months

Target: Deceleration of growth velocity to prepubertal rates

Action Threshold: Continued accelerated growth velocity may indicate inadequate suppression.

Bone Age

Frequency: Every 6-12 months

Target: Deceleration or arrest of bone age advancement

Action Threshold: Continued rapid bone age advancement may indicate inadequate suppression.

LH and FSH levels (basal or post-GnRH stimulation)

Frequency: Every 3-6 months or as clinically indicated

Target: Suppressed to prepubertal levels (e.g., LH < 4 mIU/mL after GnRH stimulation)

Action Threshold: Elevated levels indicate inadequate suppression, requiring dose adjustment or re-evaluation.

Sex Steroid Levels (Estradiol in girls, Testosterone in boys)

Frequency: Every 3-6 months or as clinically indicated

Target: Suppressed to prepubertal levels

Action Threshold: Elevated levels indicate inadequate suppression.

đŸ‘ī¸

Symptom Monitoring

  • Injection site reactions (pain, redness, swelling, abscess)
  • Headache
  • Hot flashes/flushing
  • Mood changes/emotional lability
  • Vaginal bleeding/spotting (especially during initial flare)

Special Patient Groups

🤰

Pregnancy

Contraindicated in pregnancy. Leuprolide may cause fetal harm when administered to a pregnant woman. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.

Trimester-Specific Risks:

First Trimester: High risk of fetal harm, including potential for abortion or birth defects due to hormonal effects.
Second Trimester: High risk of fetal harm.
Third Trimester: High risk of fetal harm.
🤱

Lactation

Contraindicated during breastfeeding. It is not known whether leuprolide is excreted in human milk. Due to the potential for serious adverse reactions in a breastfed infant, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Infant Risk: High risk (L5) - potential for hormonal disruption in the infant.
đŸ‘ļ

Pediatric Use

Lupron Depot-Ped is specifically indicated and dosed for the treatment of Central Precocious Puberty (CPP) in pediatric patients. Safety and efficacy have been established in this population. Close monitoring of pubertal progression and hormone levels is crucial.

👴

Geriatric Use

Not applicable for this specific pediatric formulation and indication. Leuprolide is used in geriatric populations for prostate cancer, but different formulations and dosing apply.

Clinical Information

💎

Clinical Pearls

  • The initial 'flare' effect (transient increase in sex hormones) may cause a temporary worsening of pubertal signs or vaginal bleeding/spotting in girls during the first few weeks of treatment. This is expected and usually resolves.
  • Ensure proper injection technique (subcutaneous or intramuscular) to maximize efficacy and minimize injection site reactions. Rotate injection sites.
  • Adherence to the every 3-month dosing schedule is critical for sustained suppression of puberty.
  • Treatment is typically continued until the appropriate chronological age for puberty (e.g., 11-12 years for girls, 12-13 years for boys), at which point it is discontinued to allow natural pubertal progression.
  • Monitor for psychological effects, including mood changes, as these have been reported with GnRH agonists, though causality is not fully established.
