Hepatic insufficiency, biliary obstruction, renal impairment, renaly artery stenosis. Correct volume depletion before initiating treatment. Monitor serum potassium levels regularly, especially in elderly and renally-impaired patients.
Lactation: discontinue drug or do not nurse
Indication
Hypertension,
Treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions.
Contra Indication
Severe hepatic impairment, biliary obstructive disorders. Pregnancy. Lactation.

Description
FDA has not yet classified the drug into a specified pregnancy category.
Mode of Action
Hydrochlorothiazide inhibits the reabsorption of Na and chloride in the distal tubules causing increased excretion of Na and water K and hydrogen ions.
Telmisartan is a nonpeptide AT1 angiotensin II receptor antagonist. It exerts antihypertensive activity by preventing angiotensin II from binding to AT1 receptors thus inhibiting the vasoconstricting and aldosterone-secreting effects of angiotensin II.
Interaction
Lithium, kaliuretic diuretics, laxatives, corticosteroids, ACTH, amphotericin, carbenoxolone, penicillin G, salicylates, K-sparing diuretics, K supplements, K salt substitutes drugs that cause hyperkalaemia, digitalis glycosides, antiarrhythmic agents, drugs known to induce torsades de pointes, alcohol, barbiturates, narcotics, oral antidiabetics, insulin, anion-exchange resins, NSAIDs, nondepolarising skeletal muscle relaxants, pressor amines, allopurinol, Ca salts, beta-blockers, diazoxide, anticholinergics, amantadine, cytotoxics.
Pregnancy Category Note
Pregnancy
Can cause fetal harm when administered to a pregnant woman; discontinue drug when pregnancy is dectected and treat hypertension according to guidelines during pregnancy
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
Reports of hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death owing to olihydramnios
Oligohydramnios in this setting has also been associated with fetal limb contractures, craniofacial deformation, and hypoplastic lung development
Lactation
Because of the potential for serious adverse reactions in the breastfed infant including hypotension, hyperkalemia and renal impairment, advise a nursing woman not to breastfeed during treatment with telmisartan/amlodipine
There is no information regarding the presence of telmisartan in human milk, the effects on the breastfed infant, or the effects on milk production
Limited published studies report that amlodipine is present in human milk; however, there is insufficient information to determine the effects of amlodipine on the breastfed infant
Renal impairment
Dose adjustment not necessary
Hemodialysis patients are more susceptible to hypotension
Administration
May be taken with or without food.
