What are the side effects of nifedipine short acting? Nifedipine is a dihydropyridine calcium channel blocker, the short acting formulation of which has been associated with reflex sympathetic nervous system (SNS) activation leading to flushing, tachycardia, worsening myocardial ischemia, and cerebrovascular ischemia; therefore only longer acting formulations should be used (Gibbons et al 2003).
How is Nisoldipine used as a replacement for nifedipine? The use of nisoldipine (10-20 mg b.i.d.) was evaluated as a replacement therapy for long-acting nifedipine (40-120 mg/day) in 21 patients with severe hypertension, who were resistant to or intolerant of nifedipine.
Is it safe to take nifedipine at high dosage? Nifedipine capsules should not be used to reduce blood pressure quickly as this may be fatal. The dosage of nifedipine must be established by slow titration as excessive dosages can result in hypotension, preferably over a 7 to 14 day period.

Excessive doses can result in hypotension.”
Is there an extended release version of nifedipine? Administration Nifedipine is available in both immediate and extended-release preparations. Its initial marketing was in a short-acting, immediate-release formulation that required multiple daily dosing.
How does nifedipine affect the infarct size? In the study by Muller et al, 4 nifedipine altered neither infarct size nor the 6-month follow-up, observations that are internally consistent and logical. In contrast, the 2-week data are atypical, and this short-term follow-up should at the very least be considered together with the longer-term data (Table ).
