Amlodipine (as besylate, mesylate or maleate) is a long-acting calcium channel blocker (dihydropyridine class) used as an anti-hypertensive and in the treatment of angina. 2nd or 3rd degree AV block, sick sinus syndrome, hypotension, decompensated heart failure, sinus bradycardia, severe peripheral arterial circulatory disorders, cardiogenic shock, severe asthma and bronchospasm, untreated phaeochromocytoma, Prinzmetal's angina, metabolic acidosis. Like other calcium channel blockers, amlodipine acts by relaxing the smooth muscle in the arterial wall, decreasing peripheral resistance and hence reducing blood pressure; in angina it increases blood flow to the heart muscle. May increase negative inotropic and negative dromotropic effect of antiarrhythmic drugs (e.g. May reduce antihypertensive efficacy w/ indometacin. Metoprolol selectively inhibits β1-adrenergic receptors but has little or no effect on β2-receptors except in high doses. Dizziness, insomnia, tiredness, headache, vertigo, confusion, bradycardia, shortness of breath, hypotension, Raynaud's phenomenon, CHF, peripheral oedema, cold extremities, syncope, chest pain, palpitations, gangrene, claudication, hallucinations, nightmares, visual disturbances; diarrhoea, constipation, flatulence, GI pain, heartburn, nausea, hiccups, xerostomia; bronchoconstriction, wheezing, dyspnoea; dry skin, maculopapular, psoriasiform, pruritus, worsening of psoriasis, urticarial rash. It does not exhibit membrane stabilising or intrinsic sympathomimetic activity. Rarely, Peyronie's disease, tinnitus, restless legs, musculoskeletal pain, a polymyalgia-like syndrome, decreased libido, blurred vision, dry mucous membranes, sweating; reversible alopecia, thrombocytopenia, agranulocytosis, retroperitoneal fibrosis, wt gain, arthritis, dry eyes. May antagonise β1-adrenergic stimulating effects of sympathomimetics. Onset: 1-2 hr (oral); 20 min, when infused over 10 min (IV). Time to peak plasma concentration: Approx 1.5-2 hr (oral). Metabolism: Extensively hepatic via CYP2D6 isoenzyme and undergoes oxidative deamination, O-dealkylation followed by oxidation and aliphatic hydroxylation. Additive effect w/ catecholamine-depleting drugs (e.g. Additive negative effects on SA or AV nodal conduction w/ cardiac glycosides, nondihydropyridine Ca channel blockers. Increased plasma concentrations w/ CYP2D6 inhibitors (e.g. Increased risk of hypotension and heart failure w/ myocardial depressant general anaesth (e.g. Duration: Oral: Approx 3-6 hr (immediate release); approx 24 hr (extended release). Absorption: Absorbed readily and completely from the GI tract. Distribution: Widely distributed, enters breast milk, crosses the placenta and blood-brain barrier. Excretion: Via urine (as metabolites and unchanged drug). Elimination half-life: 3-4 hr (fast hydroxylators); approx 7 hr (poor hydroxylators). Patients w/ myasthenia gravis, well-compensated heart failure, bronchospastic disease, AV conduction disorders, substantial cardiomegaly. diflucan pregnancy Or vasospastic angina (where it occurs in cycles) and without heart failure. It can be used as either monotherapy or combination therapy for the management of hypertension or coronary artery disease. Amlodipine can be administered to adults and children 6–17 years of age. Other situations occur, however, where amlodipine generally should not be used. In patients with cardiogenic shock, where the heart's ventricles are not able to pump enough blood, calcium channel blockers exacerbate the situation by preventing the flow of calcium ions into cardiac cells, which is required for the heart to pump. While use in patients with aortic stenosis (narrowing of the aorta where it meets the left ventricle) since it does not inhibit the ventricle's function is generally safe, it can still cause collapse in cases of severe stenosis. In unstable angina (excluding variant angina), amlodipine can cause a reflex increase in cardiac contractility (how hard the ventricles squeeze) and heart rate, which together increase the demand for oxygen by the heart itself.

No difference existed between metoprolol and amlodipine in terms of gout-related hospitalization P =.93 or gout-related medication use P. zithromax 3 day pack Abstract A simple, precise, specific and accurate reverse phase HPLC method has been developed for the simultaneous determination of metoprolol succinate. Objectives—To compare the effects of amlodipine and slow release metoprolol on subjective symptoms and signs of ischaemia during bicycle ergometric. A simple, precise, specific and accurate reverse phase HPLC method has been developed for the simultaneous determination of metoprolol succinate (MS) and amlodipine besylate (AB) in tablet dosage form. The chromatographic separation was achieved on Hypersil BDS cyano (250 mm x 4.6 mm, 5 microm) column using PDA detector. The mobile phase consisting of buffer (aqueous triethylamine p H 3) and acetonitrile in the ratio of (v/v) at a flow rate of 1.0 m L/min was used. The method was validated according to the ICH guidelines with respect to specificity, linearity, accuracy, precision and robustness. The method employed HPTLC aluminum plates precoated with silica gel 60Fâ?? The solvent system consisted of toluene:ethyl acetate:methanol:triethylamine (4:1:1:0.4 v/v/v). layer chromatographic method for simultaneous determination of amlodipine besylate and metoprolol succinate in bulk and pharmaceutical combined dosage form was developed and validated. The system was found to give a compact spot for amlodipine besylate (Rf = 0.39±0.02) and metoprolol succinate (Rf = 0.59±0.02). Densitometric analysis of amlodipine besylate and metoprolol succinate was carried out in the absorbance mode at 254 nm. Linear regression analysis data for the calibration plots showed good linear relationship with r2 = 0.9990±0.0013 with respect to peak area in the concentration range 400â?? 1400 ng per spot for amlodipine besylate and r2 = 0.9993±0.0013 with respect to peak area in the concentration range 3800–13300 ng per spot for metoprolol succinate. The method was validated for precision, recovery and robustness.
