  • Title: [Efficacy and tolerance of a new calcium-channel blocking agent (nitrendipine) in the treatment of arterial hypertension].
    Author: Lopes HF, Silva HB, Bellotti G, Pillegi F.
    Journal: Arq Bras Cardiol; 1990 Mar; 54(3):227-9. PubMed ID: 2288512.
    Abstract:
    PURPOSE: Assess the efficacy and tolerability of nitrendipine, 20 mg/day, in mild to moderate essential hypertension (diastolic blood pressure 95 to 114 mmHg). MATERIAL AND METHODS: Twenty patients in an open comparative trial (drug x placebo) during six weeks. Blood pressure and heart rate were measured in orthostatic and supine position and after hand-grip maneuver every two weeks. RESULTS: Systolic and diastolic blood pressure fell significatively in the treated group by the end of the study-supine (161 mmHg +/- 11 to 138 mmHg +/- 13 and 105 +/- 5 to 81 mmHg +/- 7 p less than 0.05) and orthostatic position (153 mmHg +/- 13 to 132 mmHg +/- 13 and 104 mmHg +/- 15 to 81 mmHg +/- 7, p less than 0.05) and after hand grip maneuver (170 mmHg +/- 21 to 148 mmHg +/- 22 and 108 mmHg +/- 5 to 85 mmHg +/- 7 p less than 0.05). Significant modifications were not observed in systolic and diastolic blood pressure in placebo group under the following conditions: supine (168 mmHg +/- 8 to 168 mmHg +/- 17 and 107 mmHg +/- 5 to 107 mmHg +/- 3) and orthostatic positions (167 mmHg +/- 9 to 163 mmHg +/- 14 and 107 mmHg +/- 5 to 107 mmHg +/- 4) and after hand grip maneuver (178 mmHg +/- 17 to 173 mmHg +/- 16 and 107 mmHg +/- 4 to 108 mmHg +/- 6). Significant changes in heart rate did not occur in both groups after treatment. Heart rate elevation observed after hand grip maneuver did not change. Adverse effects like headache, palpitation and dizziness occurred in both groups. Electrocardiogram, x-ray and blood chemistries were not modified during the trial.
