Description
Ramosetron Hydrochloride is the only currently available drug indicated for the treatment of male patients with IBS-D in Japan. Ramosetron Hydrochloride was approved in July 1996 under a brand name of Nasea Injection 0.3 mg and in June 1998 under a brand name of Nasea OD tablets 0.1 mg for the treatment of gastrointestinal symptoms (nausea and vomiting) associated with therapy with antineoplastic drugs (e.g., cisplatin).Nasea was launched in Japan for chemotherapy-induced emesis. Nasea was prepared by a four step sequence via the Vilsmeier-type coupling of 1-methylindole and 5-( 1- pyrrolidoncarbonyl)-4,5,6,7-tetrahydro-Hl-benzimidazole hydrochloride. The antiemetic activity arises because it is a potent 5-HT3 receptor antagonist that is i.v. and orally active. The (R)-isomer was found to be 100 times more potent than the (S)-isomer. It was able to inhibit cisplatin-induce emesis and was 8670 times more potent than netoclopramide.

Uses
Ramosetron Hydrochloride is a selective serotonin 5-HT3 receptor antagonist and has structurally different from Ondansetron (O655000), Granisetron (G780000). It controls excessive bowel movement and diarrhea by inhibiting 5-HT3 receptors in the intestinal tract. Ramosetron Hydrochloride was approved as film-coated tablets in July 2008 and as orally disintegrating tablets in August 2013 for the indication of treatment of male patients with diarrhea-predominant irritable bowel syndrome.
Brand name
Nasea
Biochem/physiol Actions
Ramosetron is a tetra hydrobenzimidazole derivative, containing an indole ring. It inhibits colon contraction mediated by serotonin, competitively. this pharmacologic property confers the drug an application in improving diarrhea-predominant inflammatory bowel syndrome. Ramosetron hydrochloride is used for PONV prophylaxis and treatment. However, ramosetron is currently only licenced for use in Japan and selected Southeast Asian countries.
Check Digit Verification of cas no
The CAS Registry Mumber 132907-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,0 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132907-72:
(8*1)+(7*3)+(6*2)+(5*9)+(4*0)+(3*7)+(2*7)+(1*2)=123
123 % 10 = 3
So 132907-72-3 is a valid CAS Registry Number.

The R- and S-enantiomers of the 4,5,6,7-tetrahydro-1H-benzimidazole derivatives 3-8 were prepared by optical resolution. Each R-isomer, except for 3, was almost two orders of magnitude more potent than its S-isomer as a 5-hydroxytryptamine (5-HT3/su
