The efficacy and safety of once-daily nifedipine coat-core when added to a regimen of atenolol (ATN; 50 mg/day) were compared with ATN and placebo in 251 patients with essential hypertension in this 12-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group study. Mean net reductions (ATN effect subtracted) in supine diastolic blood pressure at endpoint were 7.9 mmHg, 9.4 mmHg, and 9.9 mmHg at 30, 60, and 90 mg/day of nifedipine coat-core, respectively, and 4.1 mmHg on ATN+placebo. Beyond the first week of double-blind therapy, all reductions produced by nifedipine coat-core combined with ATN were statistically significant (P < 0.05) compared with ATN+placebo. On ambulatory blood pressure monitoring, trough-to-peak ratios of the change in diastolic blood pressure for the 30, 60, and 90 mg/day doses were 41%, 68%, and 78%, respectively. Adverse events were generally mild or moderate and most reflected the vasodilatory properties of nifedipine (eg, edema, headache). Nifedipine coat-core, when combined with ATN in patients not controlled by ATN alone, had significant antihypertensive activity for the entire 24-hour dosing interval and was well tolerated by the majority of patients in the study.

Cutaneous melanoma is least common (only about 1% of skin cancers) but is the deadliest malignant tumor. Moreover, amelanotic types of melanoma are very difficult for clinical diagnosis. The standard therapy can cause a lot of side effects, e.g., nausea, vomiting, and headaches, which means that novel and effective strategies are required. Interestingly, phenothiazine derivatives possess sedative, antiemetic, and anticancer activity. Our goal was to determine the effect of perphenazine and prochlorperazine on cell viability, motility, microphthalmia-associated transcription factor (MITF) and tyrosinase content in melanotic and amelanotic melanoma cells. The viability of C32 and COLO829 melanoma cells was evaluated by the WST-1 colorimetric assay; impact on motility of human melanoma was performed by wound-healing assay, while tyrosinase and MITF content were determined by Western blot. In the present study, we explore the anticancer effect of perphenazine and prochlorperazine in human melanotic (COLO829) and amelanotic (C32) melanoma cells concluding that prochlorperazine inhibits cell viability in a concentration-dependent manner, impairs motility, and decreases tyrosinase and MITF amounts. Moreover, the analyzed drugs decrease/increase MITF amount depending on the type of melanoma. We demonstrated that the decrease of MITF and tyrosinase protein induces motility inhibition of C32 cells, which suggests the ability of those drugs to restore cancer cell sensitivity to treatment. The ability of prochlorperazine to contain the spread of the amelanotic melanoma in vivo may be helpful in the development of a new and effective antimelanoma therapies.
