Diovan Hct Pharmacokinetics
Diovan Hct Interactions
See Contraindications. Concomitant renin-angiotensin system (RAS) inhibitors, K+ supplements, K+ sparing diuretics, K+-containing salt substitutes or other drugs (eg, heparin) may cause hyperkalemia and, in heart failure patients to increases in serum creatinine. Antagonized by cholestyramine, colestipol resins. Dual inhibition of the RAS with ARBs, ACEIs, or aliskiren may increase risk of hypotension, hyperkalemia, renal function changes; monitor closely, in general, avoid combined use of RAS inhibitors. Concomitant aliskiren in renal impairment (CrCl <60mL/min): not recommended. May be antagonized by, and renal toxicity potentiated by NSAIDs, including selective COX-2 inhibitors (monitor renal function periodically in elderly and/or volume-depleted). Orthostatic hypotension may be potentiated by alcohol, barbiturates, narcotics, antihypertensives. May be potentiated by inhibitors of OATP1B1 (eg, rifampin, cyclosporine) or MRP2 (eg, ritonavir). Potentiates nondepolarizing muscle relaxants. Adjust antidiabetic, antigout medications. Hyperuricemia may be potentiated by cyclosporine. May increase toxicity of digitalis, lithium (monitor). Possible symptomatic hyponatremia with carbamazepine.
Diovan Hct Adverse Reactions
Headache, dizziness, nasopharyngitis, fatigue, cough, diarrhea, orthostatic hypotension, electrolyte disturbances (eg, hypokalemia, hyponatremia, hypomagnesemia), hyperuricemia, increased serum cholesterol or triglycerides; rare: rhabdomyolysis; HCTZ: increased risk for non-melanoma skin cancer.
