A long-term, open-label study to confirm the safety of topical diclofenac solution containing dimethyl sulfoxide in the treatment of the osteoarthritic knee.

To assess the long-term safety of a topical solution of diclofenac sodium in a vehicle containing dimethyl sulfoxide (TDiclo), subjects with radiologically confirmed, symptomatic osteoarthritis of the knee(s) applied the clinical dose of TDiclo (40 drops, four times daily) to each painful knee for up to 52 weeks. Safety assessment included adverse events, skin irritation scores of the treated knee(s), ocular examinations, and routine laboratory tests. There were 793 subjects (mean age, 62.

Efficacy and safety of topical diclofenac containing dimethyl sulfoxide (DMSO) compared with those of topical placebo, DMSO vehicle and oral diclofenac for knee osteoarthritis.

While topical non-steroidal anti-inflammatory drugs are considered safe, their long-term efficacy for osteoarthritis has been suspect. We conducted a 12-week, double-blind, double-dummy, randomized controlled trial of topical diclofenac (TDiclo) in a vehicle solution containing dimethyl sulfoxide (DMSO) in 775 subjects with radiologically confirmed, symptomatic primary osteoarthritis of the knee. This 5-arm study compared TDiclo with a placebo solution, the DMSO vehicle, oral diclofenac (ODiclo) and the combination of TDiclo+ODiclo for relieving the signs and symptoms of knee osteoarthritis.

One-year outcomes and health care utilization in survivors of severe acute respiratory syndrome.

Background: Severe Acute Respiratory Syndrome (SARS) became a global epidemic in 2003. Comprehensive information on 1-year outcomes and health care utilization is lacking. Research conducted during the SARS outbreak may help inform research planning for future public health emergencies.

False-positive amplified Mycobacterium tuberculosis direct test results for samples containing Mycobacterium leprae.

Nucleic acid amplification tests are widely used in mycobacteriology laboratories to rapidly detect Mycobacterium tuberculosis complex directly in clinical specimens. A positive result provides an early diagnosis of tuberculosis, allowing initiation of appropriate therapy and public health measures.

Treatment of osteoarthritis of the knee with a topical diclofenac solution: a randomised controlled, 6-week trial [ISRCTN53366886].

Background: Topical NSAIDs have been proven to relieve the symptoms of osteoarthritis (OA) in short-term studies (2 weeks). To justify its chronic use, efficacy of a topical NSAID over a longer term of study should be demonstrated. The efficacy and safety of a topical diclofenac solution over a 6-week treatment course in symptomatic primary OA of the knee was investigated.

Efficacy and safety of a topical diclofenac solution (pennsaid) in the treatment of primary osteoarthritis of the knee: a randomized, double-blind, vehicle-controlled clinical trial.

Background: Oral nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to relieve the symptoms of osteoarthritis (OA) but can produce harmful systemic effects and end-organ damage. A topical NSAID formulation may provide symptom relief with fewer adverse effects. A new topical diclofenac sodium solution-containing the absorption enhancer dimethyl sulfoxide-was evaluated for the relief of the symptoms of primary OA of the knee.

Equivalence study of a topical diclofenac solution (pennsaid) compared with oral diclofenac in symptomatic treatment of osteoarthritis of the knee: a randomized controlled trial.

Objective: . To compare the safety and efficacy of a topical diclofenac solution versus oral diclofenac in relieving the symptoms of primary osteoarthritis (OA) of the knee, in a randomized, double-blind, double-dummy equivalence trial.

Methods: A total of 622 men and women with radiological evidence of primary knee OA and mild to severe symptoms were randomly assigned to treatment with a topical diclofenac solution plus placebo oral capsules, or placebo topical solution plus oral diclofenac (50 mg) capsules.

Effect of a topical diclofenac solution for relieving symptoms of primary osteoarthritis of the knee: a randomized controlled trial.

Background: Treatment of osteoarthritis with oral NSAID therapy provides pain relief but carries a substantial risk of adverse effects. Topical NSAID therapy offers an alternative to oral treatment, with the potential for a reduced risk of side effects. The objective of this trial was to assess the safety and efficacy of a topical diclofenac solution in relieving the symptoms of primary osteoarthritis of the knee.

Enhanced human nail drug delivery: nail inner drug content assayed by new unique method.

The purpose of this study was to develop an assay method of the human inner nail plate and to compare nail drug penetration by a penetrating enhancing formulation (the test carrier formulation). The test carrier and saline formulations were tested using radiolabeled urea, ketoconazole, and salicylic acid. After twice dosing daily for 7 days on human nail plates, the under inner section of the nail plate was assayed for absorbed drug content using a unique drilling/removal system.
