Switching from high doses of pure μ-opioid agonists to transdermal buprenorphine in patients with cancer: a feasibility study

Journal of Opioid Management

Abstract

Several myths on buprenorphine's pharmacology exist: possible analgesic ceiling effect, feasibility of combination with other opioid agonists, and the reversibility of side effects. Aim to evaluate: 1) if cancer patients receiving high doses of pure agonists could obtain adequate pain relief after switching to transdermal (TD) buprenorphine and 2) whether the numbers of breakthrough pain episodes after switching increased and whether they could be treated with the same doses of pure agonist as before switching. The prospective open multicenter study included outpatients with moderate-to-severe cancer pain satisfactorily controlled. Patients were switched from the usual pure agonist to TD buprenorphine and were titrated to a stable dose. The assessments were: 1) daily self-assessment of pain intensity, numbers of rescue medications, and pain interference with sleep; 2) brief pain inventory; 3) pain relief and pain intensity; 4) quality of life; and 5) adverse events and symptoms. Eighteen patients receiving 150-516 mg of morphine/day were included. The buprenorphine dose at the end of the study varied between 52.5 and 140 μg/h. No difference in pain before and after switching was shown. The level of rescue doses was maintained. ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
