Patients of cirrhosis aged 18 to 75 years who have no esophageal varices will be enrolled. After baseline evaluation, the participants will be randomized to receive either Placebo or Carvedilol 6.25 mg BD. After randomization they will be followed up for one year.

The investigators hypothesized that efficacy of carvedilol is equal to the efficacy of placebo in the pre primary prophylaxis of esophageal varices in cirrhosis.

Primary Outcome Measures:
  • the proportions of patients who develop esophageal varices at 1 year in each group. [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • complications of cirrhosis (ascites, hepatic encephalopathy, SBP), [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Number of patient dying in a period of one year [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
  • Number of patients needing discontinuation of therapy due to adverse effects. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 132
Study Start Date: September 2010
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Carvedilol
Tablet 6.25 mg BD
Drug: carvedilol
Carvedilol will be administered orally at a start dose of 3.125 mg twice daily. After 1 week, this will increased if systolic blood pressure does not fall below 90 mm Hg. The patient will receive the maximum tolerated dose of carvedilol with a maximum of 6.25 BD.
Placebo Comparator: placebo
Placebo tablets 2 BD
Drug: Placebo
The placebo tablets will be identical to the carvedilol tablets. First the patients will receive placebo in the dose of 1 BD. Then depending on his tolerance it will be increased to a maximum of 2 BD.
