synthesis and biological evaluation of new 1, 4-dihydropyridines as antihypertensives agents in rats
new analogues of nifedipine, as a known calcium channel blocker, were synthesized by replacing the orthonitrophenyl group on position 4 with 1-(4-nitrobenzyl)-5-imidazolyl or 2-methylthio-1-(4-nitrobenzyl)-5-imidazolyl substituent. effects of the new synthesized compounds on blood pressure were studied at 15, 30 and 60 min after administration by indirect tail-cuff method and compared with nife...
Background: Calcium channel blockers have an important role in treatment of various cardiovascular diseases including hypertension, angina pectoris and cardiac arrhythmias, so study of cardiovascular effects of derivatives of these drugs are useful. Nifedipine is one of these drugs that used widely to treat hypertension and other cardiovascular diseases. The aim of the present study was to eval...

Background: Threatened preterm labor (TPL) is the leading cause of hospitalization during pregnancy. Tocolytic agents are the primary therapeutic options for TPL. The aim of this study is to compare intramuscular progesterone with oral nifedipine as a tocolytic agent. Methods: This randomized controlled trial was carried out in a teaching hospital (Shahid Akbarabadi) in Tehran, Iran, from De...
Background: The succinylcholine administration and tracheal intubation causes significant rise of intraocular pressure (I.O.P), which is of special concern in penetrating ophthalmic injuries. Different methods have been suggested to prevent this complication, but none of them were completely successful. Reports of use of calcium channel blocking agents specially nifedipine for prevention of I.O...
mice were rendered tolerant and dependent to morphine by subcutaneous injection of morphine over a period of 5 days. the effects of acute and chronic administration of dihydropyridine calcium channel antagonist nifedipine on the development of tolerance and naloxone-precipitated morphine withdrawal signs were investigated. a single injection of nifedipine proved to be effective in inhibiting so...
OBJECTIVE A calcium antagonist, nifedipine, causes gingival overgrowth as a side effect. It has been confirmed that the Japanese traditional medicine, Saireito, inhibits the nifedipine-induced proliferation of gingival fibroblasts in vitro. We performed an in vivo experiment to determine whether Saireito has a therapeutic use in the treatment of nifedipine-induced gingival overgrowth. METHODS...
In this study a comparison was made between the efficacy and side effects of nifedipine and magnesium sulfate in inhibition of preterm labor. 74 cases in preterm labor were randomized to either oral nifedipine (n = 34) or intravenous magnesium sulfate (n = 40). All cases were primigravid with singleton pregnancies and gestational ages of 23-36 weeks. Both groups were similar in terms of age, ge...
Depression, a bewildering and burdensome illness, is one of the commonest psychiatric diseases. It is expected to be the second leading contributor to Global Disease Burden by 2020. The objective of the study was to determine the effect of nifedipine on the responses of imipramine, sertraline and furosemide in the forced swim test (FST) and tail suspension test (TST) in mice. Groups of mice wer...
the electrochemical behavior of nifedipine (i), nitrendipine(ii) and their photodegradation products has been studied by employing electrochemical techniques in chloroform and in 1:4 mixture of chloroform-isopropanol using piperidinium perchlorate (ppc) as supporting electrolyte. it has been shown that i and ii undergo in a 4e, 4h+ irreversible reduction reaction, while the reduction product, p...
