Nimodipine is the current gold standard in the treatment of subarachnoid hemorrhage, as it is the only known calcium channel blocker that has been proven to improve neurological outcomes. In addition, nimodipine exhibits neuroprotective properties in vitro under various stress conditions. Furthermore, clinical studies have demonstrated a neuroprotective effect of nimodipine after vestibular schwannoma surgery.

In the present analysis, we investigated the association between alcohol consumption and ambulatory blood pressure (BP) control in male patients after 8 weeks of antihypertensive therapy with two dihydropyridine calcium channel blockers. The study participants were hypertensive (clinic systolic/diastolic BP of 140-179/90-109 mmHg and 24-hour ambulatory systolic/diastolic BP ≥ 130/80 mmHg) patients enrolled in a randomized controlled trial and treated with amlodipine 5-10 mg or nifedipine gastrointestinal therapeutic system (GITS) 30-60 mg once daily. Alcohol consumption was classified as non-drinkers and drinkers.

Novel, «green» and simple visible spectrophotometric procedures for the determination of six dihydropyridines CCBs (amlodipine besylate (AML), lacidipine (LAC), levamlodipine besylate (LAML), nifedipine (NIF), nimodipine (NIM) and nitrendipine (NIT)) through derivatization with the sulfophthalein dye bromophenol blue (BPB) have been developed. The optimal parameters for CCBs spectrophotometric analysis via complex formation using BPB were as follows: detection wavelength-596 nm, reaction time-5 min, ratio of reacting components-1:1, operating temperature-25 ± 2 °C. The concentration was linearly proportional to absorbance values in the range of 3.

Intermittent hypoxemia (IH), a pathophysiologic consequence of obstructive sleep apnea (OSA), adversely affects insulin sensitivity, insulin secretion, and glucose tolerance. Nifedipine, an L-type calcium channel blocker frequently used for the treatment of hypertension, can also impair insulin sensitivity and secretion. However, the cumulative and interactive repercussions of IH and nifedipine on glucose homeostasis have not been previously investigated.

Background: Several chemical studies described the physiological efficacy of 1,4- dihydropyridines (DHPs). DHPs bind to specific sites on the α1 subunit of L-type calcium channels, where they demonstrate a more pronounced inhibition of Ca2+ influx in vascular smooth muscle compared to myocardial tissue. This selective inhibition is the basis for their preferential vasodilatory action on peripheral and coronary arteries, a characteristic that underlies their therapeutic utility in managing hypertension and angina.
