Information source: Pfizer
ClinicalTrials.gov processed this data on August 23, 2015
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Healthy Lactating Women

Intervention: pregabalin (Lyrica) (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Pfizer

Official(s) and/or principal investigator(s):
Pfizer CT.gov Call Center, Study Director, Affiliation: Pfizer


This is a pharmacokinetic study to determine the safety and tolerability of pregabalin in healthy lactating women. The objectives are to determine whether pregabalin is secreted in breast milk and if so, to characterize pregabalin pharmacokinetics in breast milk. Other objectives are to estimate potential infant exposure to pregabalin if administered to lactating women and to characterize the safety and tolerability of pregabalin in lactating women.

Clinical Details

Official title: A Multiple Dose Pharmacokinetic Open Label Study Of Pregabalin (Lyrica) In Healthy Lactating Women

Study design: Allocation: Non-Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Single Group Assignment, Masking: Open Label

Primary outcome:

Ae.tau.urine [Amount recovered in urine during the dosing interval, tau (12 hours)]

"Area Under the Curve from Time Zero to end of dosing interval (AUCtau) (plasma and breast milk)"

Clr [Renal clearance; Urine Ae(tau)/ Plasma AUC(tau)]

"Maximum Observed Plasma Concentration (Cmax) (plasma and breast milk)"

"Time to Reach Maximum Observed Plasma Concentration (Tmax) (plasma and breast milk)"

"Half-Life (t1/2) (plasma)"

Caverage (plasma only)

Minimum Observed Plasma Trough Concentration (Cmin) (plasma only)

Apparent Oral Clearance (CL/F) (plasma only)

Ae.tau.bm [Amount excreted in breast milk over the dosing interval tau (12 hours)]

"CL.bm [Breast milk clearance Ae(tau)bm/plasma AUC(tau)]"

"Half-Life (t1/2) ( breast milk)"

Detailed description: Post approval commitment for the FDA


Minimum age: 18 Years. Maximum age: 45 Years. Gender(s): Female.


Inclusion Criteria:

- Healthy lactating females between the ages of 18 and 45 years (inclusive) who are

actively breast-feeding or expressing breast milk and are at least 12 weeks post partum.
