Propinox: Mechanism of Action, Dosage, Contraindications, Side Effects, Interactions and Storage

Treatment of abdominal colic includes pain relievers such as non-steroidal anti-inflammatory drugs, as well as antispasmodic agents.

Propinox is an antispasmodic drug frequently used in the treatment of abdominal cramps , disorders of the gastrointestinal tract, uterus, and gallbladder, although little is known about its relaxing activity in gallbladder tissue.

The term abdominal colic is used to describe spasmodic abdominal pain, which arises as a result of distention, inflammation, or obstruction. It is often characterized as sharp, localized abdominal pain that increases, spikes, and subsides.

Although it is often a benign complaint, it can also be a sign of a more significant pathology, therefore a careful medical history and physical examination are crucial to the approach to a differential diagnosis.

Mechanism of action of propinox / pharmacokinetics

After administration of a parenteral dose, the plasma half-life of lysine clonixinate and propinox is approximately 1 hour.

Lysine clonixinate is extensively metabolized, eliminating more than 60% of the administered dose in the urine, while propinox is mostly excreted in the urine in unchanged form.

Propinox hydrochloride, also known as pargeverine hydrochloride, an antispasmodic substance that has a double mechanism of pharmacological action: musculotropic and anticholinergic.

Propinox also functions as a musculotropic agent, acting directly on visceral smooth muscle cells and conferring their antispasmodic activity. The anticholinergic (propinox activity) is derived from a moderate and non-selective blockade of cholinergic muscarinic fibers.
