Although contraindicated, coingestion of alcohol and opioids by patients or drug abusers is a major health concern because of dangerous additive and potentially life-threatening sedative and respiratory effects. In addition, alcohol has been shown to disrupt the extended-release characteristics of certain extended-release opioid formulations, releasing a hazardous amount of opioid over a short time period. Morphine sulfate and naltrexone hydrochloride extended release capsules (MS-sNT), which contain naltrexone sequestered in each pellet core, are indicated for management of chronic, moderate to severe pain.

If the product is tampered with by crushing, naltrexone, a μ-opioid antagonist, is intended for release to mitigate morphine-induced subjective effects.

Six drugs with a potential to interact with colesevelam were studied in open-label, randomized clinical studies. The presence of a drug interaction was concluded if the 90% confidence intervals for the geometric least squares mean ratios of AUC(0-t) (AUC(0-48) for levothyroxine) and C(max) fell outside the no-effect limits of (80.

This study evaluated the safety and pharmacokinetics of midostaurin following multiple oral doses of midostaurin for 28 days at 4 dose levels (25 mg bid, 50 mg bid, 75 mg bid, 75 mg tid), as well as a single oral 100-mg dose in patients with diabetes mellitus (n = 9-13 per dose cohort). Pharmacokinetic parameters were determined on days 1 and 28 based on the plasma concentrations of midostaurin and its metabolites, CGP62221 and CGP52421.

Because the available immediate-release formulation requires multiple daily dosing and has been associated with rebound hypertension on abrupt cessation, an extended-release (ER) formulation has been developed for study of efficacy and tolerability parameters in patients with ADHD.
Objective: This trial was primarily undertaken to determine the effect on blood pressure (BP) of abrupt cessation versus taper-down of guanfacine ER.
