CARDENE SR vs TRIVARIS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nicardipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It produces relaxation of coronary vascular smooth muscle and dilation of coronary arteries, and also dilates peripheral arteries, reducing systemic vascular resistance and blood pressure.
TRIVARIS combines an opioid agonist-antagonist (buprenorphine) and a mu-opioid receptor antagonist (naloxone). Buprenorphine partially binds to mu-opioid receptors, reducing withdrawal and craving, while naloxone precipitates withdrawal if injected, deterring abuse.
Initial: 30 mg orally twice daily (SR capsules). Titrate up to 60 mg twice daily. Usual maintenance: 30-60 mg twice daily.
TRIVARIS 10 mg orally once daily, with or without food.
