Brand Name :Telpride AM
Composition :Eachtablet Contain Telmisartan 40mg + Amlodepin 5mg
It is a competitive antagonist of angiotensin-2 atAT-1 receptor. It decreases peripheral resistance and lowers BP in hypertensiveindividuals. It blocks all overt actions of angiotensin-2 such as: 1.Vasoconstriction, 2. Central & Peripheral sympathetic stimulus, 3. Releaseof aldosterone and adrenaline, 4. Salt and water reabsorption, 5. Centralactions like thirst, vasopressin release, and growth promoting actions on heartand blood vessels.
Amlodipine is a second generation dihydropyridineCa channel blocker. It exerts it`s antihypertensive, antianginal actionsthrough blocking the influx of Ca ions through voltage gated L-type Ca channelsto the peripheral vascular smooth muscle cells, Coronary smooth muscle cellsand to the myocardial cells. Thus causes dilatation of vascular endothelium,decrease peripheral resistance, & reduce myocardial oxygen demand .Itmarkedly relax arterioles and milder effects on veins. They do not compromisehaemodynamics and cerebral and renal perfusion.
Absorption: Absorbedorally, bioavailability is about 42%
Distribution: Itis distributed in to the body in a highly protein bound form.
Metabolism: Metabolizedby glucuronide conjugation in to an inactive metabolite.
Excretion: Excretedmainly through faeces and rest is excreted through urine.
Absorption: Wellabsorbed orally.
Distribution: Widelydistributed in a protein bound form.
Metabolism: Metabolizedin liver, but there is no active metabolite
ACE inhibitors: Thiazide diuretics:Potentiates effect of these drugs.
Beta Blockers : Best avoided, especially by those withimpaired LV function due to depressant effect on myocardial contractibility
or AV conduction.
Fentanyl: Severe hypotension orincreased fluid volume requirements.
