OBJECTIVE To quantify the efficacy and safety of naproxen, ibuprofen, mefenamic acid, aspirin and acetaminophen (paracetamol) in the treatment of primary dysmenorrhoea through a systemic overview of randomised controlled trials. METHODS MEDLINE, EMBASE and the Science Citation Index were searched for randomised controlled trials. Efficacy was assessed by(More)
OBJECTIVES To review the outcome measures commonly used in phase III treatment trials of relapsing-remitting multiple sclerosis and to introduce a method of data analysis which is clinically appropriate for the often reversible disability in this type of multiple sclerosis. METHODS The conventional end point measures for disability change are inadequate(More)
A systematic literature search of clinical trials of evening primrose oil (EPO) for the treatment of the premenstrual syndrome (PMS) was carried out with a view to performing a meta-analysis. Only seven placebo-controlled trials were found but only in five trials was randomization clearly indicated. Inconsistent scoring and response criteria made(More)
OBJECTIVE To evaluate the comparative efficacy and tolerability of paracetamol-dextropropoxyphene combination and paracetamol through a systematic overview of randomised controlled trials. DESIGN Systematic retrieval of trials of paracetamol-dextropropoxyphene, paracetamol, and placebo to allow pooling of results from head to head comparison trials and(More)
The potencies of four proprietary corticosteroid creams were ranked using blanching measured by a tristimulus colour analyser as an index. Intra-subject variation was measured in a trial using a single subject while in a second study inter-subject variation was quantified using six volunteers. Discriminative parameters were derived from the extended(More)
The objective of this study was to quantify the analgesic efficacy of paracetamol and its combination with codeine or caffeine through a systematic overview and meta-analysis of relevant randomized controlled trials (RCTs). Systematic retrieval of relevant clinical trials was carried out using computerized searches, historical searches and communication(More)
A high-performance liquid chromatographic (HPLC) assay of paracetamol and its metabolites is described. The method for quantifying the metabolism of paracetamol in children with chronic liver disease and the good correlation between plasma and salivary concentrations of paracetamol is demonstrated. Despite an increasing bias between the two methods with(More)
In vitro absorption of three angiotensin converting enzyme (ACE) inhibitors, captopril, enalapril and lisinopril, and their stabilities in aqueous buffer as well as their resistance to intestinal and dermal tissue homogenates were investigated. The results demonstrate that the spontaneous oxidation of captopril, enalapril and lisinopril followed first-order(More)
Flupenthixol dihydrochloride in aqueous solution oxidized to trifluoromethylthioxanthone, ethanol, and piperazine via aldehydic and epoxidic intermediates in the presence of air. The formation rate of trifluoromethylthioxanthone increased with increases in pH and oxygen concentration. Buffer ions also affected the decomposition rate. Micelle formation by(More)
BACKGROUND Minocycline is a tetracycline antibiotic that is commonly used in the treatment of moderate to severe acne vulgaris. Although it is more convenient for patients to take than first-generation tetracyclines, as it only needs to be taken once or twice a day and can be taken with food, it is more expensive. Concerns have also been expressed over its(More)
