a study of the effect of ly2189265 on two blood pressure drugs

Conditions: Diabetes Mellitus, Type 2

Summary: the purpose of this study is twofold: 1. to evaluate the effect of ly2189265 on how the body absorbs a blood pressure lowering drug (lisinopril) in participants with high blood pressure who are currently taking lisinopril. 2. to evaluate the effect of ly2189265 on heart rate and blood pressure in healthy volunteers when taken with a beta-blocker drug (metoprolol). in part 1, participants will receive four weekly injections of ly2189265 with continued use of normal lisinopril therapy. part 2 is a cross-over study design. participants will receive a single injection of ly2189265 in one period, and seven daily doses of metoprolol and a single injection of ly2189265 in another period.

esophageal reflux). participants having had cholecystectomy (removal of gall bladder) in the past with no further sequelae, may be included in the study at the discretion of the screening physician * have a history or presence of thyroid disease, unless have been on a stable dose of thyroxine replacement therapy for at least 1 month * show history or evidence of significant active neuropsychiatric disease * have personal or family history of medullary thyroid cancer (mtc) or a genetic condition that predisposes to mtc * regularly use known drugs of abuse and/or show positive findings on urinary drug screening * show evidence of human immunodeficiency virus (hiv) infection and/or positive human hiv antibodies * show evidence of hepatitis c and/or positive hepatitis c antibody * show evidence of hepatitis b and/or positive hepatitis b surface antigen * intend to start new concomitant medication during the study, including over-the-counter and herbal medication, use drugs that directly reduce gastrointestinal motility or who regularly use systemic corticosteroids, or potent, inhaled, or intranasal steroids known to have a high rate of systemic absorption * have donated more than 500 milliliters (ml) of blood within the month prior to screening * have a nondominant arm circumference of greater than 42 centimeters (cm) * have an average weekly alcohol intake that exceeds 21 units per week (males up to age 65) and 14 units per week (males over 65 and females), or are unwilling to stop alcohol consumption from 48 hours before each admission until discharge from the unit, and to limit alcohol intake to a maximum of 2 units/day on all other days from screening through 48 hours prior to the follow-up visit.
