Concurrent administration of colesevelam reduces the systemic exposure and peak plasma concentration of olmesartan. Olmesartan should be administered at least 4 hours before colesevelam.
Compared with Caucasian patients, Black patients have a reduced blood pressure response to monotherapy with angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers; however, the reduced response is largely eliminated if combination therapy that includes an adequate dose of a diuretic is instituted.
For pediatric patients who cannot swallow tablets, the same dose can be given using an extemporaneous suspension: (for 200 mL of a 2 mg/mL suspension): Add 50 mL of purified water to an amber polyethylene terephthalate (PET) bottle containing twenty olmesartan 20 mg tablets and allow to stand for a minimum of 5 minutes. Shake the container for at least 1 minute and allow the suspension to stand for at least 1
minute. Repeat 1-minute shaking and 1-minute standing for four additional times. Add 100 mL of Ora-Sweet (R) and 50 mL of Ora-Plus(R) to the suspension and shake well for at least 1 minute.
