Indications of Carvista 25
A medication called Carvista 25 is used to treat excessive blood pressure, angina, and heart failure. The blood arteries are relaxed as a result, allowing for easier blood flow to the heart. Blood pressure reduction aids in reducing the risk of future heart attacks and strokes.
Pharmacology
Carvedilol is a cardiovascular drug whose main pharmacological action is to non-selectively antagonize ?-adrenergic receptors, but it also has obvious adrenergic antagonist activity. It also has antiproliferative properties and is an active free radical scavenger. It is used to treat hypertension, angina pectoris, and congestive heart failure.
Dosage & Administration
In hypertension: Initially, 12.5 mg once daily, increased after 2 days to the usual dose of 25 mg once daily; if necessary the dose may be further increased at intervals of at least 2 weeks to a maximum of 50 mg daily in single or divided doses. In elderly patients, the initial dose of 12.5 mg daily may provide satisfactory control.
In angina pectoris: the recommended dose for initiation of therapy is 12.5 mg twice daily for the first 2 days. Thereafter, the recommended dosage is 25 mg twice daily. For elderly patients, the maximum daily dose is 50 mg daily in divided doses.
In heart failure: Initially, 3.125 mg twice daily (with food) may be given, the dose may be increased at intervals of at least 2 weeks to 6.25 mg twice daily, then to 12.5 mg twice daily, then to 25 mg twice daily. The dose may be increased to the highest dose tolerated, a maximum of 25 mg twice daily in patients less than 85 kg body weight and 50 mg twice daily in patients over 85 kg.
Interaction of Carvista 25
Digoxin: In normal healthy volunteers, a single dose of carvedilol and a single dose of digoxin will cause a significant increase in digoxin levels after 24 hours. Carvedilol was also administered to patients with stable congestive heart failure with digoxin without adverse reactions. When initiating, adjusting, or stopping the carvedilol dose, increased digoxin monitoring is recommended.
Rifampin: Pretreatment with rifampin causes Cmax and AUC to increase by 60 ?.
Warfarin: Carvedilol does not change the binding of warfarin to plasma proteins in vitro.
Clonidine: ?-receptor antagonists can enhance the pressure increase that may occur after abrupt cessation of clonidine treatment, although theoretically, the blocking effect of carvedilol should change the increase in pressure.
Contraindications
Carvedilol is contraindicated for decompensated heart failure, bronchial asthma or related bronchospasm, second or third-degree atrioventricular block, and sick sinus syndrome (unless it has been placed permanently). Pacemaker), cardiogenic shock, or severe patients with bradycardia.

The safety and efficacy of carvedilol in children have not been established. Carvedilol should not be used during pregnancy as it has not been studied in this group. Animal studies have shown that carvedilol can cross the placental barrier. There is no information on the safety and efficacy of carvedilol in newborns.
