The purpose of this study is to establish the bioequivalence of the hormones norgestimate, norelgestromin, and ethinyl estradiol in norgestimate/ethinyl estradiol (NGM/EE) tablets, formulated by wet process compared with the same hormones in NGM/EE tablets, formulated by dry process, in healthy women.
This is a Phase 1, single-dose, open-label (a medical research study in which participants and researchers are told which treatments the participants are receiving, "unblinded"), randomized (the study medication is assigned by chance), single-center and a 2-way crossover (method used to switch participants from one study group to another in a clinical trial) study in healthy women. The study consists of 3 parts: Screening phase, Treatment phase and end-of-study or withdrawal. Treatment periods will be separated by a wash out period of at least 10 days. The duration of participation in the study for an individual participant will be approximately 7 weeks. All participants will be randomly assigned in a 1:1 ratio to 1 of 2 possible treatment sequences and receive both of the following treatments: 1 oral tablet formulated by wet process or dry process, whereas each tablet contains norgestimate 250 microgram (mcg) and ethinyl estradiol 35 mcg. The primary endpoint of the study will be assessment of pharmacokinetic parameters. Participants' safety will be monitored throughout the study.

Maximum Plasma Concentration (C[max])
The C(max) is the maximum serum concentration which will be observed at the defined time points.
Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-last])
The AUC (last) is the area under the plasma concentration-time curve from time zero time of the last quantifiable concentration C(last), and C(last) is the last observed quantifiable concentration.
Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity])
The AUC (infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z), wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time; and C(last) is the last observed quantifiable concentration; and lambda(z) is elimination rate constant.
Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
Time to Reach the Maximum Plasma Concentration (T[max])
The T\[max\] is time to reach the observed maximum plasma concentration.
Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
Percentage of AUC(0-infinity)
Percentage of AUC(0-infinity) is calculated as (AUC\[0-infinity\] minus AUC\[0-last\] divided by AUC\[0-infinity\]) multiplied by 100.

Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
Elimination Half-life Period (t1/2)
Elimination half-life associated with the terminal slope (lambda\[z\]) of the semi logarithmic drug concentration-time curve, calculated as 0.693/lambda (z).
Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
Terminal slope (Lambda [z])
Terminal slope is defined by first-order rate constant associated with the terminal portion of the curve, determined as the negative slope of the terminal log-linear phase of the drug concentration-time curve.
Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
Coefficient of Determination (r^2)
The coefficient of determination is a goodness of fit statistic that gives the proportion of the variance of one variable that is predictable from the other variable.
Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
Adjusted Coefficient of Determination (r^2 adj.)
The coefficient of determination adjusted (r\^2 adj.) for the number of points used in the estimation of lambda\[z\].
Time frame: Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2
