Clinical drug investigation
-
Achieving the maximum reduction in cardiovascular morbidity and mortality is the primary goal of blood pressure (BP) control. Current guidelines recommend several antihypertensive classes as first-line therapy for this purpose but the decision on which agent/s to use will likely be based upon the treating physician's clinical experience. Observational studies provide a useful way of ascertaining the efficacy and tolerability of an antihypertensive in a real-life clinical setting. ⋯ Long-acting nifedipine GITS/OROS, alone or in combination with other antihypertensive agents, provides effective and well tolerated treatment of hypertension in a broad spectrum of patients routinely seen in day-to-day clinical practice.

Randomized Controlled Trial Comparative Study
Metabolic and haemostatic effects of estradiol valerate/dienogest, a novel oral contraceptive: a randomized, open-label, single-centre study.
The hormonal components of combined oral contraceptives (COCs) have various metabolic and haemostatic effects. The objective of this study was to compare the metabolic and haemostatic effects of a novel COC comprising estradiol valerate/dienogest (E(2)V/DNG) with ethinylestradiol/levonorgestrel (EE/LNG). ⋯ E(2)V/DNG had a minimal impact on metabolic and haemostatic parameters, and a more favourable effect than EE/LNG on lipid markers.

Randomized Controlled Trial Comparative Study
Treatment comparison of budesonide/formoterol with salmeterol/fluticasone propionate in adults aged > or =16 years with asthma: post hoc analysis of a randomized, double-blind study.
Three fixed maintenance-dose inhaled corticosteroid/long-acting beta(2)-agonist (ICS/LABA) combinations for the treatment of asthma are currently available: salmeterol/fluticasone propionate (Seretide/Advair/Adoair) budesonide/formoterol (Symbicort) and beclometasone/formoterol (Foster). All of these combinations have proven efficacy in terms of controlling symptoms, improving lung function and reducing the rate of exacerbations compared with ICSs and LABAs administered separately. Budesonide/formoterol is also approved for use as maintenance and reliever therapy in a number of countries (Symbicort SMART). Many of the studies supporting the use of budesonide/formoterol combination therapies have included populations of adolescents and adults aged >11 years. ⋯ Budesonide/formoterol fixed maintenance dose or maintenance and reliever therapy provides similar improvements in current asthma control and reduces the future risk of hospitalizations/emergency-room treatments versus salmeterol/fluticasone propionate fixed maintenance-dose treatment, providing additional clinical benefit to asthma patients aged > or =16 years.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy and safety of Tapentadol extended release compared with oxycodone controlled release for the management of moderate to severe chronic pain related to osteoarthritis of the knee: a randomized, double-blind, placebo- and active-controlled phase III study.
Tapentadol is a novel, centrally acting analgesic with mu-opioid receptor agonist and norepinephrine reuptake inhibitor activity. ⋯ treatment with Tapentadol ER 100-250 mg twice daily or oxycodone HCl CR 20-50 mg twice daily was effective for the management of moderate to severe chronic osteoarthritis-related knee pain, with substantially lower incidences of gastrointestinal-related TEAEs associated with treatment with Tapentadol ER than with oxycodone CR.

Randomized Controlled Trial Multicenter Study Comparative Study
Ketoprofen versus paracetamol (acetaminophen) or ibuprofen in the management of fever: results of two randomized, double-blind, double-dummy, parallel-group, repeated-dose, multicentre, phase III studies in children.
Fever is a common symptom in children and one of the major concerns of parents of younger and preschool-age children. To compare the efficacy and safety of ketoprofen with that of paracetamol (acetaminophen) and ibuprofen in the treatment of febrile conditions in children. Two prospective, randomized, double-blind, double-dummy, repeated-dose, multicentre, phase III studies with two parallel groups in each study were conducted in primary-care outpatient clinics. ⋯ Use of ketoprofen was not associated with any increased risk of adverse events compared with the two reference compounds. Ketoprofen 0.5 mg/kg appeared to be equivalent to the standard antipyretic doses of the reference products ibuprofen 5 mg/kg and paracetamol 15 mg/kg. Ketoprofen at the 0.5 mg/kg dose should be an effective and safe option for symptomatic management of fever in children.
