Arilol Tablet Uses

Arilol Tablet contains Carvedilol. Arilol uses:

(Carvedilol) is indicated for the treatment of mild or moderate {NYHA (New York Heart Association) class II or III} heart failure of ischemic or cardiomyopathic origin, in conjunction with digitalis, diuretics and ACE inhibitor, to reduce the progression of disease as evidenced by cardiovascular death, cardiovascular hospitalization, or the need to adjust other heart failure medications. Carvista (Carvedilol) may be used in patients unable to tolerate an ACE inhibitor. Carvista (Carvedilol) may be used in patients who are not receiving digitalis, hydralazine or nitrate therapy.

Arilol Tablet Doses

Arilol Tablet contains Carvedilol 12.5 mg. Arilol doses:

In heart failure, initially 3.125 mg twice daily (with food) may be given, 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 highest dose tolerated, maximum 25 mg twice daily in patients less than 85 kg body-weight and 50 mg twice daily in patients over 85 kg.In hypertension initially 12.5 mg once daily, increased after 2 days to usual dose of 25 mg once daily; if necessary the dose may be further increased at intervals of at least 2 weeks to maximum 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.

 

Side Effects

Postural hypotension, dizziness, headache, fatigue, gastro-intestinal disturbances, bradycardia; occasionally diminished peripheral circulation, peripheral oedema and painful extremities, dry mouth, dry eyes, eye irritation or disturbed vision, impotence, disturbances of micturition, influenza-like symptoms, rarely angina, AV block, exacerbation of intermittent claudication or Raynaud's phenomenon, allergic skin reactions, exacerbation of psoriasis, nasal stuffiness, wheezing, depressed mood, sleep disturbances, paresthesia, heart failure, changes in liver enzymes, thrombocytopenia, leukopenia are also reported.

Introduction

(Carvedilol) is a cardiovascular drug whose main pharmacological action is non-selective antagonism of β-adrenergic receptors but which also possesses appreciable α-adrenergic antagonistic activity. It also has antiproliferative properties and is a scavenger of reactive free oxidant radicals. It is used in the treatment of hypertension, angina pectoris and congestive heart failure.

Arilol Precaution

Take caution in hepatic impairment and in heart failure monitor clinical status for 2-3 hours after initiation and after increasing each dose. Before increasing dose ensure that the renal function and heart failure are not deteriorating.

Interaction

Drug interactions have been seen with co-administration of carvedilol and digoxin, resulting in an increased bioavailability of digoxin. This increase is not clinically significant and does not correlate with pharmacologic response. Pharmacokinetics studies demonstrated a lack of drug interaction between carvedilol and hydrochlorothiazide, cimetidine, torsemide and warfarin

Pregnancy Lactation use

Carvedilol should not be used during breast-feeding, since no studies have been performed in lactating women and animal studies have shown that carvedilol is excreted in breast milk. Safety and efficacy in children have not been established with carvedilol. Carvedilol should not be used during pregnancy as no studies have been performed in this group. Animal studies have shown that carvedilol crosses the placental barrier. No information is available on safety and efficacy of Carvedilol use in neonates.

Contraindication

Carvedilol is contraindicated in patients with severe chronic cardiac failure requiring intravenous inotropic therapy, bronchial asthma or related bronchospastic conditions, second or third-degree AV block, sick sinus syndrome (unless a permanent pacemaker is in place), cardiogenic shock, or severe bradycardia. Use of carvedilol in patients with clinically manifested hepatic impairment is not recommended. Carvedilol is contraindicated in patients with hypersensitivity to the drug.

Special Warning

The safety and efficacy of carvedilol in paediatric patients have not been established.

Acute Overdose

Symptoms: Severe hypotension, bradycardia, heart failure, cardiogenic shock and cardiac arrest. Resp problems, bronchospasms, vomiting, lapses of consciousness and generalised seizures. 

Management: Symptomatic and supportive treatment. Consider use of atropine for excessive bradycardia, IV glucagon or sympathomimetics to support ventricular function. Consider using norfenephrine or noradrenaline if vasodilation dominates the intoxication profile and IV inj of diazepam or clonazepam for seizures.

Interaction with other Medicine

Digoxin : In normal healthy volunteers a single dose of carvedilol taken together with a single dose of digoxin resulted in significantly increased levels of digoxin 24 hour later. Patients with congestive heart failure stabilized on digoxin have been given carvedilol concomitantly without any adverse effects. Increased monitoring of digoxin is recommended when initiating, adjusting, or discontinuing the dose of carvedilol.

Rifampin : Pretreatment with rifampin resulted in a 60% decrease in Cmax and AUC.

Warfarin : Carvedilol did not alter the in vitro plasma protein binding of warfarin.

Clonidine : b-receptor antagonists potentiate the pressor reaction which may follow sudden withdrawal of treatment with clonidine although, in theory, the a-blocking action of carvedilol should modify the pressure rise.

Storage Condition

Store in a cool and dry place. Protect from light and moisture.
