Brief Summary:
If tigecycline clearance increases with body size then serum exposure values will be lower in obese class III compared to normal weight subjects because exposure changes inversely with clearance when the dose is fixed without regard to weight.

Condition or disease Intervention/treatment Phase
Obesity Drug: Tigecycline Phase 4

Detailed Description:
Not required

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 12 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: Pharmacokinetics Of Tigecycline In Morbidly Obese Subjects
Study Start Date : March 2012
Actual Primary Completion Date : May 2012
Actual Study Completion Date : May 2012

Resource links provided by the National Library of Medicine

Drug Information available for: Tigecycline

Arm Intervention/treatment
All subjects receive a single dose of tigecycline
Drug: Tigecycline
100 mg IV as a single infusion over 30 minutes
Other Name: Tygacil

Primary Outcome Measures :
  1. Single-dose Serum AUC of Tigecycline Between Time 0 and 96 Hours [ Time Frame: 4 days (96 hours) ]
    The AUC is the area under the concentration time curve in serum measured in the unit of concentration in milligram of tigeycline per liter of plasma multiplied by the time interval in hours (hour*mg/L)
