Actions of Pelidone in details
Pharmacology: Pharmacodynamics: Pelidone is a selective peripheral dopamine antagonist at the D2 dopamine receptors in the chemoreceptor trigger zone (CTZ) and stomach. It does not readily enter into the central nervous system (CNS) (the CTZ is considered to lie outside the blood brain barrier). It increases spontaneous gastric activity and antagonises dopamine inhibition of gastric emptying. Pelidone has been shown to increase lower esophageal sphincter pressure and promotes esophageal and antral peristalsis and also increases pyloric dilation. It increases the frequency, amplitude and duration of duodenal contraction and reduces the small bowel transit time. Pelidone has no acetylcholine-like effect.
Pharmacokinetics: Pelidone is rapidly and almost completely (93%) absorbed after oral administration. Peak plasma concentrations occur within 30 min after oral administration. Pelidone is strongly bound to plasma proteins (91-93%), lipoprotein binding being as important as albumin binding. Although tissue distribution studies are lacking in man, rat studies show widespread tissue distribution except to the CNS. Only small amounts of Pelidone cross the placenta or reach breast milk.
Pelidone undergoes extensive biotransformation with <1% excreted unchanged in urine. The effects of hepatic disease have not been documented; severe renal impairment may prolong the half-life (t½) of Pelidone. However, the contribution of renal clearance to total plasma clearance of Pelidone is so small that accumulation of Pelidone should not occur.
How should I take Pelidone?
Dosing
The dose of Pelidone will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of Pelidone. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
- For oral dosage form (tablets):
- Treatment of gastrointestinal motility disorders:
- Adults—10 milligrams (mg) three to four times daily. Some patients may require higher doses up to 20 mg three or four times daily.
- Nausea and vomiting:
- Adults—20 milligrams (mg) three to four times daily.
- Treatment of gastrointestinal motility disorders:
Missed Dose
If you miss a dose of Pelidone, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Storage
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Pelidone administration
Should be taken on an empty stomach. Take 15-30 min before meals.
Pelidone pharmacology
Gastrointestinal emptying (delayed) adjunct; peristaltic stimulant: The gastroprokinetic properties of Pelidone are related to its peripheral dopamine receptor blocking properties. Pelidone facilitates gastric emptying and decreases small bowel transit time by increasing esophageal and gastric peristalsis and by lowering esophageal sphincter pressure. Antiemetic: The antiemetic properties of Pelidone are related to its dopamine receptor blocking activity at both the chemoreceptor trigger zone and at the gastric level.
