Randomized Controlled Trial Comparative Study
Premedication with sublingual morphine sulphate in abdominal surgery.
Treatment with analgesics before surgery may be effective in reducing post-operative pain. This approach is defined as "pre-emptive analgesia" and recent reviews show conflicting results. ⋯ In patients undergoing elective abdominal surgery, premedication with sublingual morphine sulphate results in a better control of post-operative pain, compared to premedication with sublingual midazolam. The beneficial effect of pre-operative sublingual morphine sulphate was apparent in the immediate post-operative period and was sustained over the 48-hour assessment period.

Monotherapy with any class of antihypertensive drug effectively controls blood pressure (BP) in only about 50% of patients. Consequently, the majority of patients with hypertension require combined therapy with two or more medications. This study aimed to evaluate the effectiveness (systolic BP [SBP]/diastolic BP [DBP] control) and tolerability of the fixed-dose combination enalapril/nitrendipine 10 mg/20 mg administered as a single daily dose in hypertensive patients. ⋯ The rate of SBP/DBP control achieved demonstrates the effectiveness of the fixed-dose enalapril/nitrendipine 10 mg/20 mg combination administered as a single daily dose in patients with essential hypertension not adequately controlled with monotherapy or with any combination other than enalapril + nitrendipine. The proportion and type of adverse events reported were as expected and have already been described for both components of the enalapril/nitrendipine 10 mg/20 mg combination. These results confirm the effectiveness of a strategy based on a fixed-dose enalapril/nitrendipine 10 mg/20 mg combination in reducing BP and achieving BP control goals.
