Sublingual nitroglycerin may be taken as required for the control of acute manifestations of angina, particularly during Procardia titration. Since steady-state plasma levels are achieved on the second day of dosing, titration may proceed more rapidly, if symptoms so warrant, provided the patient is assessed frequently.

In patients with renal disease or congestive heart failure, therapy resulting in central volume expansion is not without hazard. Treatment of nitroglycerin overdose in these patients may be subtle and difficult, and invasive monitoring may be required. It's an impressive finding, agrees Sampath Parthasarathy, PhD, director of gynecology and obstetrics research at Atlanta's Emory University. On the other hand, other research suggests that taking multivitamins that contain vitamin C for 10 years seems to prevent cataracts. Use of supplements for shorter periods does not appear to work.

Several well-controlled, randomized trials studied the use of immediate-release nifedipine in patients who had just sustained myocardial infarctions. In none of these trials did immediate-release nifedipine appear to provide any benefit. In some of the trials, patients who received immediate-release nifedipine had significantly worse outcomes than patients who received placebo. Procardia capsules should not be administered within the first week or two after myocardial infarction, and they should also be avoided in the setting of acute coronary syndrome when infarction may be imminent.

For example, you may get a when you drive over a high mountain pass, hike to a high altitude, or arrive at a mountain resort. Common cold. There is some controversy about the effectiveness of vitamin C for treating the common cold. Experience with nifedipine overdosage is limited. Generally, overdosage with nifedipine leading to pronounced hypotension calls for active cardiovascular support including monitoring of cardiovascular and respiratory function, elevation of extremities, and judicious use of calcium infusion, pressor agents and fluids. Clearance of nifedipine would be expected to be prolonged in patients with impaired liver function. Since nifedipine is highly protein bound, dialysis is not likely to be of any benefit; however, plasmapheresis may be beneficial. This drug may also be used to treat certain blood circulation disorders Raynaud's syndrome.

Ranitidine produced smaller, non-significant increases. The effect may be mediated by the known inhibition of cimetidine on hepatic cytochrome P-450, the enzyme system probably responsible for the first-pass metabolism of nifedipine. If nifedipine therapy is initiated in a patient currently receiving cimetidine, cautious titration is advised. The manufacturer product information should be consulted.

Comparison of propranolol and hydrochlorothiazide for the initial treatment of hypertension: II. Results of long-term therapy. JAMA. Dosing regimens for most chronically used drugs are designed to provide plasma concentrations that are continuously greater than a minimally effective concentration. This strategy is inappropriate for organic nitrates. Several well-controlled clinical trials have used exercise testing to assess the antianginal efficacy of continuously delivered nitrates. In the large majority of these trials, active agents were indistinguishable from placebo after 24 hours or less of continuous therapy. Attempts to overcome nitrate tolerance by dose escalation, even to doses far in excess of those used acutely, have consistently failed. Only after nitrates have been absent from the body for several hours has their antianginal efficacy been restored. Wyeth Laboratories.
