Nitrendipine Tablets
Function and Efficacy
1This product is a dihydropyridine calcium channel blocker. 2This product inhibits the transmembrane calcium ion influx of vascular smooth muscle and myocardium, but its vascular action is mainly vascular, so its vascular selectivity is relatively strong. 3This product causes the dilation of systemic blood vessels such as coronary arteries and renal arterioles, producing a hypotensive effect.

Special Population Medication
Precautions for children: Not clear yet. Precautions for pregnancy and lactation: The research on the use of this product in pregnant women is not sufficient, and the existing clinical application has not caused any problems, but attention should be paid to adverse reactions. Precautions for the elderly: The blood concentration of the drug is higher in the elderly, but the half-life is not prolonged, so the dose should be appropriately reduced; patients who are taking beta-receptor blockers should be cautious when adding this product. It is advisable to start with a small dose when combined with other drugs to prevent inducing or aggravating systemic hypotension, increasing the incidence of angina pectoris, heart failure, and even myocardial infarction. The recommended initial dose for elderly patients is 10 mg (1 tablet) per day.
Drug Interactions
1. The combination of y-receptor blockers and this drug can enhance the antihypertensive effect in most patients and reduce the tachycardia that occurs after the blood pressure is lowered by this drug; however, some patients may induce and aggravate systemic hypotension, heart failure and angina pectoris. 2. The combination of angiotensin-converting enzyme inhibitors is well tolerated and the antihypertensive effect is enhanced. 3. The combination of long-acting nitrates is well tolerated, but there is still a lack of literature evaluating the effectiveness of this combination in controlling angina pectoris. 4. Some studies on digitalis suggest that taking this drug can increase the plasma concentration of digoxin in combination, with an average increase of 45%. Some studies believe that it does not increase the plasma concentration and toxicity of digoxin. It is suggested that we should monitor the blood concentration of digoxin when using it for the first time, adjusting the dose or stopping the use of nitrendipine to prevent digoxin overdose or underdose. 5. There are no reports that the combined use of nitrendipine can increase the prothrombin time of coumarin anticoagulants. At present, the interaction between them cannot be confirmed. 6. Cimetidine: Since cimetidine can mediate the inhibition of liver cytochrome P450 enzymes and change the first-pass effect of nitrendipine, it is recommended that patients who are taking cimetidine should pay attention to the adjustment of drug dosage when taking nitrendipine in combination.
