Aspra SR Tablet (Sustained Release)

Aspra SR belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the gastric mucosa, omeprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the final step of acid production. This effect is dose-related and leads to inhibition of both basal and stimulated acid secretion irrespective of the stimulus.

Clinical advantage of omeprazole mups tablet compared to conventional modified-release omeprazole tablets and pellet-filled omeprazole capsules:

  • Ensures greater bioavailability
  • Ensures uniform emptying of micro pellets from stomach into small intestine facilitates rapid dissolution of enteric coating and drug release resulting in early Tmax and Cmax (peak time and peak plasma concentration)
  • Ensures lesser possibility of dose dumping
  • Is a combination of fast acting and sustained action
  • Ensures uniform drug release
  • Once daily dosing
  • Ensures lesser chance of localized irritation
  • Ensures better and more uniform drug absorption
  • Better than capsules in reducing the esophageal residence time
  • Minimizes fluctuation in plasma concentration of drug


Each film coated MUPS tablet contains 20 mg Aspra SR enteric coated micro pellets

Aspra SR (Multiple-Unit Pellet System) is indixated in-

  • Duodenal and Gastric ulcers
  • NSAID-induced gastric and duodenal ulcers
  • Reflux Oesophagitis
  • GERD (Gastroesophageal Reflux Disease)
  • Eradication of H. pylori with appropriate antibiotics
  • Zollinger-Ellison Syndrome

MUPS is abbreviation for Multiple-Unit Pellet System. However, from pharmaceutical industry and research perspective, the term in general refers to MUPS compacted into tablets. Thus, the resulting tablets prepared by compaction of modified release coated multiparticulates or pellets are called as MUPS. It is the more recent and challenging technology that combines the advantages of both tablets and pellet filled capsules in one dosage form.

MUPS ensure rapid and uniform gastric emptying and subsequently uniform drug dissolution of pellets in the gastrointestinal tract due to their small size and larger surface, uniform drug absorption is facilitated which results in consistent and controlled pharmacological action.

A further reduction in inter- and intra-subject variability in drug absorption and clinical response is facilitated since the number of pellets per MUPS dosage form is much more than a conventional pellet-filled capsule and possibility of dose dumping(in stomach) and incomplete drug release is further minimized.
