- Mechanism of action
Colloidal bismuth subcitrate is very effective in the treatment of gastroduodenal disorders and appears to act via several mechanisms. It has little acid-neutralizing effect and does not affect acid secretion. It is uncertain whether it affects pepsin secretion, but it does inhibit peptic activity. It causes an increase in mucus glycoprotein secretion and may also bind to the gastric mucus layer to act as a diffusion barrier to HCl. It accelerates ulcer healing and causes an accumulation of epidermal growth factor around the ulcer. In addition, it has a cytoprotective effect and increases mucosal secretion of prostaglandins and bicarbonate. It has bactericidal effects against Helicobacter pylori (which is associated with gastritis and peptic ulcers). It also prevents adhesion of H. pylori to epithelial cells and can inhibit enzymes secreted by H. pylori, such as proteases, lipases, glycosidases, and phospholipases.
Target Actions Organism UATP-dependent Clp protease ATP-binding subunit ClpX antagonistHelicobacter pylori (strain ATCC 700392 / 26695) - Absorption
The mean peak whole-blood bismuth level after ingestion of colloidal bismuth subcitrate (214 mg bismuth) was more than 50 mg/liter and occurred at 30 minutes. After ingestion of bismuth subnitrate (205 mg bismuth), however, there was no evidence of bismuth absorption into blood, although in three of the volunteers who took bismuth subnitrate a week after colloidal bismuth subcitrate, baseline levels of blood bismuth were still elevated. Forty-five minutes after taking colloidal bismuth subcitrate, mean plasma levels for all five volunteers were also assessed and were 79.76 microg/liter as compared to blood levels of 47.6 microg/liter.

- Route of elimination
Elimination of bismuth is primarily through urinary and biliary routes.
- Half-life
The elimination half-life of bismuth is approximately 5 days
- Clearance
The rate of renal elimination appears to reach steady state 2 weeks after treatment discontinuation with similar rates of elimination at 6 weeks after discontinuation. The average urinary elimination of bismuth is 2.6% per day in the first two weeks after discontinuation (urine drug concentrations 24 to 250 mcg/mL) suggesting tissue accumulation and slow elimination.

- Avoid alcohol. Avoid ingesting alcohol during therapy with Pylera and for three days after discontinuation as it may cause flushing, nausea, and vomiting.
- Take after a meal. The overall exposure to bismuth subcitrate potassium was not significantly impacted by administration with food when tested in the combination product Pylera.
