Brief Summary:
This study compared the bioavailability of two formulations 100 mg (one capsule or other respectively) of each one of the products, of Minocycline, under fasting conditions, in healthy Mexican volunteers of both sexes. The single dose study under fasting (10 hours prior to study) conditions, cross, with two treatments, two periods, two sequences (2x2) randomized sequence, balanced, and with a washout period of at least 7 days between each dose, in 24 healthy volunteers.

Primary Outcome Measures :
  1. Bioavailability as assessed by composite of PK parameters. [ Time Frame: The samples were collected for each period to 0.0, 0.33, 0.66, 1.0, 1.33, 1.66, 2.0, 2.33, 2.66, 3.0, 4.0, 6.0, 8.0, 12.0, 16.0, 24.0, 36.0, 48.0 and 72.0 hours after administration ]
    The following pharmacokinetic (PK) parameters will assessed maximum observed concentration (Cmax), Area under the concentration time curve from time zero (pre-dose) to last common time of quantifiable concentration within a subject across all treatments (AUC0-t) and Area under the concentration time curve from time zero (pre-dose) extrapolated to infinite time (AUC0-inf).
