warnings and cautions
5 WARNINGS AND PRECAUTIONS Hypotension: Correct volume or salt depletion prior to administration. ( 5.2 ). Monitor renal function and potassium in susceptible patients Increased angina or myocardial infarction with calcium channel blockers may occur upon dosage initiation or increase ( 5.3 ). Observe for signs of fluid or electrolyte imbalance ( 5.6 ). Exacerbation or activation of systemic lupus erythematosus ( 5.8 ). Acute angle-closure glaucoma ( 5.9 ). Sprue-like enteropathy has been reported. Consider discontinuation of Tribenzor in cases where no other etiology is found ( 5.10 ). 5.1 Fetal Toxicity Olmesartan medoxomil. Tribenzor can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death. When pregnancy is detected, discontinue Tribenzor as soon as possible [ see Use in specific Populations ( 8.1 ]. Hydrochlorothiazide. Thiazides cross the placental barrier and appear in cord blood. Adverse reactions include fetal or neonatal jaundice and thrombocytopenia [see Use in Specific Populations (8.1) ]. 5.2 Hypotension in Volume- or Salt-Depleted Patients Olmesartan medoxomil. In patients with an activated renin-angiotensin system, such as volume- and/or salt-depleted patients (e.g., those being treated with high doses of diuretics) symptomatic hypotension may be anticipated after initiation of treatment with olmesartan medoxomil. Initiate treatment with Tribenzor under close medical supervision. If hypotension does occur, place the patient in the supine position and, if necessary, give an intravenous infusion of normal saline. A transient hypotensive response is not a contraindication to further treatment, which usually can be continued without difficulty once the blood pressure has stabilized. Amlodipine. Symptomatic hypotension is possible, particularly in patients with severe aortic stenosis. Because of the gradual onset of action, acute hypotension is unlikely. 5.3 Increased Angina and /or Myocardial Infarction Amlodipine. Patients, particularly those with severe ...

adverse reactions
6 ADVERSE REACTIONS Most common adverse reactions (incidence ≥2%) are dizziness, peripheral edema, headache, fatigue, nasopharyngitis, muscle spasms, nausea, upper respiratory tract infection, diarrhea, urinary tract infection, and joint swelling ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, Cosette Pharmaceuticals, Inc. at 1-800-922-1038 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Tribenzor In the controlled trial of Tribenzor, patients were randomized to Tribenzor (olmesartan medoxomil/amlodipine/hydrochlorothiazide 40/10/25 mg), olmesartan medoxomil/amlodipine 40/10 mg, olmesartan medoxomil/hydrochlorothiazide 40/25 mg, or amlodipine/hydrochlorothiazide 10/25 mg. Subjects who received triple combination therapy were treated between two and four weeks with one of the three dual combination therapies. Safety data from this study were obtained in 574 patients with hypertension who received Tribenzor for 8 weeks. The frequency of adverse reactions was similar between men and women, patients 300,000 patient-years. In the sub-group of diabetic patients receiving high-dose olmesartan (40 mg/d) for > 6 months, there appeared to be an increased risk of death (HR 2.0, 95% CI 1.1, 3.8) compared to similar patients taking other angiotensin receptor blockers. In contrast, high-dose olmesartan use in non-diabetic patients appeared to be associated with a decreased risk of death (HR 0.46, 95% CI 0.24, 0.86) compared to similar patients taking other angiotensin receptor blockers. No differences were observed between the groups receiving lower doses of olmesartan compared to other angiotensin blockers or those receiving therapy for < 6 months. Overall, these data raise a concern of a possible increased CV risk associated with the use of high-dose olmesartan in diabetic patients. There are, however, concerns with the credibility of the finding of increased CV risk, notably the observation in the large epidemiologic study for a survival benefit in non-diabetics of a magnitude similar to the adverse finding in diabetics. Amlodipine. The following post-marketing event has ...
