Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Effect of eprosartan and enalapril in the treatment of black hypertensive patients: subgroup analysis of a 26-week, double-blind, multicentre study. Eprosartan Multinational Study Group.
A double-blind comparator study was performed in 528 hypertensive patients [baseline sitting diastolic blood pressure (SitDBP) 95-114 mmHg]. The primary objective was to compare the incidence of drug-related cough in patients treated with enalapril and eprosartan. The secondary objective was to compare antihypertensive efficacy between treatments. ⋯ In conclusion, eprosartan is effective and appears to be safe in black hypertensive patients. The combination of eprosartan and HCTZ was also well tolerated and provided additional efficacy in those patients not responding to eprosartan alone. The incidence of treatment-associated cough in the black subgroup was low, but there were no apparent differences between treatment groups.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of etodolac (Ultradol) with acetaminophen plus codeine (Tylenol #3) in controlling post-surgical pain in vasectomy patients.
The efficacy and safety of etodolac (Ultradol) and acetaminophen plus codeine [A + C (Tylenol #3)] in controlling post-surgical pain were compared in an open-label, randomized, parallel-group outpatient study. Patients who were voluntarily having a vasectomy performed for sterilization were assigned to receive either etodolac 200 mg (20 patients) or A + C (20 patients). All medication was taken as required for up to 7 days. ⋯ Results of the study indicated that patients taking etodolac were more likely to say they could return to work 24 hours after their vasectomy (p = 0.04). There were no other statistically significant differences between the two groups of patients. The results from this study indicate that etodolac and A + C are equally efficacious and well-tolerated for the control of post-vasectomy pain and that patients may observe an increased benefit with etodolac by being able to return to work sooner.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Ibuprofen and diclofenac sodium in the treatment of osteoarthritis: a comparative trial of two once-daily sustained-release NSAID formulations.
An investigator-blind, parallel-group, multicentre study was undertaken to compare the efficacy and tolerability of once-daily, sustained-release (s-r) ibuprofen and diclofenac sodium in patients (mean age 59.8 years) suffering from painful osteoarthritis affecting chiefly the knee and/or hip. Patients attending eight Swiss centres received either two s-r tablets of ibuprofen (daily dose 1600 mg; n = 30) or a single s-r diclofenac 100 mg tablet (n = 31) each evening for 21 days. Clinical assessments were performed prior to initiating therapy and after 7 and 21 days of treatment. ⋯ In conclusion, although both NSAID treatments improved the clinical condition of patients with painful osteoarthritis, statistically significant differences in favour of once-daily s-r ibuprofen (1600 mg) were demonstrated in terms of efficacy, indicating a potential therapeutic advantage for this formulation. Ibuprofen was also better tolerated than diclofenac sodium (100 mg/day), the latter being associated with gastrointestinal side effects in a significant proportion of patients. Sustained-release ibuprofen (Brufen Retard) thus represents an important addition to the available therapeutic armamentarium of once-daily NSAID formulations.

Randomized Controlled Trial Comparative Study Clinical Trial
Investigation into the duration of action of sustained-release ibuprofen in osteoarthritis and rheumatoid arthritis.
The duration of action of sustained-release ibuprofen ('Brufen Retard') was investigated in a 14-day double-blind study involving 14 osteoarthritis and 10 rheumatoid arthritis patients. The recommended once-daily dosage of this preparation (1600 mg taken in the evening) provided effective control of arthritic symptoms for both patient groups, with significant overall improvements in pain and stiffness compared to baseline. ⋯ The 24-hour clinical action underlying these findings is consistent with ibuprofen plasma profiles obtained with the sustained-release preparation in earlier pharmacokinetic studies. It is likely that the greater sensitivity of rheumatoid patients to withdrawal of a single day's active treatment in this study reflects a more severe inflammatory disease process than that of the osteoarthritis patients.

Randomized Controlled Trial Multicenter Study Clinical Trial
The efficacy and tolerability of controlled-release dihydrocodeine tablets and combination dextropropoxyphene/paracetamol tablets in patients with severe osteoarthritis of the hips.
A double-blind, parallel group study was undertaken in general practice to compare the efficacy of and tolerability to controlled-release (CR) dihydrocodeine tablets and combination dextropropoxyphene/paracetamol tablets in patients with severe osteoarthritis of the hip(s). Eighty-six patients were randomly allocated to receive either CR dihydrocodeine (60 mg) tablets (1 tablet twice daily to 2 tablets daily) or combination dextropropoxyphene (32.5 mg)/paracetamol (325 mg) tablets (2 tablets 3-times daily to 2 tablets 4-times daily) for a period of 2 weeks. Patients recorded in a diary card 4 times a day the severity of their pain and each morning whether or not they woke during the night due to pain in their hip(s). ⋯ Tolerance in terms of withdrawals or side-effect profile did not appear to the dosage of each preparation administered. It is concluded that after 2-weeks' treatment CR dihydrocodeine provided superior analgesia to dextropropoxyphene/paracetamol with no difference in side-effects. Furthermore, CR dihydrocodeine has the advantage of twice rather than 3 or 4-times daily dosing.
