Autoimmune gastrits (AIG) is a chronic inflammatory disease of the stomach occurring in up to 8% of the general population.
It is a chronic inflammatory disease with destruction of parietal cells of the corpus and fundus of the stomach. The known consequence is vitamin B12 deficiency and, consequently, pernicious anemia. However, loss of parietal cells reduces secretion of gastric acid which is also required for absorption of inorganic iron; thus, iron deficiency is commonly found in patients with autoimmune gastritis. This usually precedes vitamin B12 deficiency and is found mainly in young women.
Despite symptomatic treatment of AIG based on iron infusions, vitamin B12 injections and endoscopic surveillance, there is no curative treatment for autoimmune gastritis at this moment.
The present invention provides a novel, efficient and locally effective treatment for autoimmune gastrits (AIG) using drug delivery system for gastroretentive release the glucocorticoids in a timely and locally controlled manner.
- improving activity span for short half-life drugs
- increased contact time for the drug
- increased bioavailability of drugs
- reduction of the number of dosages per period of time
- minimization or elimination of local and/or systemic side effects
- minimization of drug accumulation associated with chronic dosing
- improved efficiency and safety of treatment
- reduced fluctuation of drug level
and better patient compliance with overall disease management.
