Description
Sources: https://www.accessdata.fda.gov/drugsatfda_docs/label/2009/016862s041s042lbl.pdf
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/6151117 | https://www.ncbi.nlm.nih.gov/pubmed/21215785 | https://www.drugs.com/propoxyphene.html

Propoxyphene is a centrally acting opiate analgesic. Propoxyphene is an odorless, freely soluble in water, white crystalline powder with a bitter taste. In vitro studies demonstrated propoxyphene and the metabolite norpropoxyphene inhibit sodium channels (local anesthetic effect) with norpropoxyphene being approximately 2 fold more potent than propoxyphene and propoxyphene approximately 10 fold more potent than lidocaine. Propoxyphene and norpropoxyphene inhibit the voltage-gated potassium current carried by cardiac rapidly activating delayed rectifier (hERG) channels with approximately equal potency. It is unclear if the effects on ion channels occur within therapeutic dose range. Propoxyphene is indicated for the relief of mild to moderate pain.

Sample Use Guides

In Vivo Use Guide

Darvon-N (Propoxyphene) is given orally. The usual dosage is one 100 mg propoxyphene napsylate tablet every 4 hours as needed for pain. The maximum dose of Darvon-N is 6 tablets per day. Do not exceed the maximum daily dose.

Route of Administration: Oral

In Vitro Use Guide

Cell membrane preparation (Chemiscreen™ MOR) expressing recombinant human MOR were used for activity evaluation. The assays were performed in microtiter plates with 40 mkL of binding buffer or Propoxyphene (1–100,000 mkM), 10 mkL of radioligand (2 nM (3H)-DAMG), and 50 mkL of diluted membranes with three wells per group. The plates were then incubated at room temperature for 2h. The binding incubation was terminated by the addition of 100 mkL cold binding buffer to each well. The glass fiber filter plates were presoaked for 30–45 min with 0.33% PEI buffer. The PEI solution was removed from the filter plate with a vacuum manifold (Millipore) and the filters washed with 200 mkL priming buffer (50 mM HEPES, 0.5% BSA, pH 7.4) per well. The binding reaction was transferred to the filter plate and washed with 200 mkL washing buffer (50 mM HEPES with 500 mM NaCl and 0.1% BSA, pH 7.4).
