Hello and welcome to HCM.
Thank you for your query.
The main role of treatment in peptic ulcer disease
is at first killing any infections that are present, reducing acid production, reducing pain by treating the spasm, and treating the symptoms (gas, etc.)
DS: is an anti-spasmodic which will relax the region where the ulcer is present, and avoid pain and further worsening of the condition
Librax: It helps in treating abdominal cramps, spasms and relieves anxiety
related to gastric problems
Rabonik Plus: Helps in reducing acid production, which if high (acid) will irritate and further aggravate your condition.
I feel your therapy is slightly incomplete, as it concentrates only on symptoms management. I would suggest the addition of antibiotic therapy and bismuth compounds (which would help in ulcer healing).
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
