Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of the analgesic effects of a fixed-dose combination of orphenadrine and diclofenac (Neodolpasse) with its single active ingredients diclofenac and orphenadrine: a placebo-controlled study using laser-induced somatosensory-evoked potentials from capsaicin-induced hyperalgesic human skin.
The aim of this study was to investigate the analgesic efficacy of Neodolpasse, a fixed-dose combination of orphenadrine and diclofenac, compared with those of its single active ingredients in a human pain model. ⋯ This study demonstrated the efficacy of Neodolpasse in a human pain model. The observed effect was mainly caused by central mechanisms and was found to be superior for the fixed-dose combination of orphenadrine and diclofenac compared with the individual ingredients. Both components contributed to the effect of the combination in an additive fashion, which can be explained by the different molecular mechanisms of action of each drug.

Efaproxiral [RSR 13, GSJ 61, JP 4, KDD 86, RS 4] is a synthetic, small-molecule, radiation-sensitising agent being developed by Allos Therapeutics primarily for the treatment of cancer. It works by binding and allosterically stabilising deoxyhaemoglobin in hypoxic regions of tumour tissue. This increases oxygen uptake of the tumour tissue and restores its sensitivity to radiation therapy, making therapy potentially more successful. ⋯ To penetrate the non-oncology market in the US, the company will seek partnership with one or more pharmaceutical companies with direct sales forces and with established distribution systems. Allos is also hoping to secure an oncology marketing partner for non-North American territories. At the time, the company had been issued 21 patents in the US, Canada, Europe and Japan.

Lasofoxifene [CP 336156] is a potent, nonsteroidal, tissue-selective estrogen receptor modulator (SERM). It has the bone-sparing and cardioprotective effects of estrogen, but lacks estrogen's uterine cancer risk. Lasofoxifene is under development with Ligand Pharmaceuticals and Pfizer (formerly Parke-Davis) for the prevention of postmenopausal osteoporosis and breast cancer. ⋯ Lasofoxifene is under clinical evaluation as a treatment for vaginal atrophy. According to Pfizer's pipeline in November 2004, the company anticipates regulatory submission for vaginal atrophy by the end of 2004. In June 2002, Ligand estimated that lasofoxifene has the potential to reach sales of US dollars 1-2 billion, pending approval.

To investigate the effects of mild to moderate hepatic impairment on the pharmacokinetics and pharmacodynamics of landiolol hydrochloride, a new ultra-short-acting beta1-adrenergic antagonist. ⋯ The pharmacokinetic and pharmacodynamic characteristics of this ultra-short-acting beta1-blocker were maintained even in the patients with hepatic impairment. Although we did not observe any drug-related adverse events in these patients, hypotension or bradycardia should be considered, necessitating continuous monitoring of both heart rate and BP in patients with hepatic impairment who receive landiolol hydrochloride.

Randomized Controlled Trial Comparative Study Clinical Trial
Volume efficacy and reduced influence on measures of coagulation using hydroxyethyl starch 130/0.4 (6%) with an optimised in vivo molecular weight in orthopaedic surgery : a randomised, double-blind study.
Different types of hydroxyethyl starch (HES) affect blood coagulation differently. We studied the effects of HES 130/0.4 on coagulation in major orthopaedic surgery in relation to the pharmacological parameter in vivo molecular weight. ⋯ HES 130/0.4 and HES 200/0.5 were found to be similar with regard to volume efficacy. Sensitive coagulation parameters returned more rapidly to normal in the HES 130/0.4 group. Lower in vivo molecular weight and more rapid excretion of HES 130/0.4 are the likely explanations for the smaller influence on coagulation in this group.
