Cardilock50 mg

Cardilock 50 mg is indicated- In the management of hypertension. It may be used alone or concomitantly with other antihypertensive agents, particularly with a thiazide-type diuretic. For the long-term management of patients with angina pectoris. In the management of hemodynamically stable patients with defnite or suspected acute myocardial infarction to reduce cardiovascular mortality.

Beta-adrenoceptor blocking drugs, Beta-blockers

The synthesis of Cardilock 50 mg resulted from attempts to produce a β-adrenoceptor antagonist that would competitively block β1 (cardiac) receptors but have no effect on β2-receptors. It is classified as a β1 selective (cardioselective) β-adrenergic receptor antagonist with no membranestability activity and no partial agonist activity. It is markedly the most hydrophilic of the currently available β- blockers and thus penetrates the lipid of cell membranes poorly

Hypertension: The initial dose of Cardilock 50 mg is 50 mg given as one tablet a day either alone or added to diuretic therapy. The full effect of this dose will usually be seen within one to two weeks. If an optimal response is not achieved, the dosage should be increased to Cardilock 50 mg 100 mg given as one tablet a day. Increasing the dosage beyond 100 mg a day is unlikely to produce any further benefit.Angina Pectoris: he initial dose of Cardilock 50 mg is 50 mg given as one tablet a day. If an optimal response is not achieved within one week, the dosage should be increased to Cardilock 50 mg 100 mg given as one tablet a day. Some patients may require a dosage of 200 mg once a day for optimal effect.Twenty-four hour control with once daily dosing is achieved by giving doses larger than necessary to achieve an immediate maximum effect. The maximum early effect on exercise tolerance occurs with doses of 50 to 100 mg, but at these doses the effect at 24 hours is attenuated, averaging about 50% to 75% of that observed with once a day oral doses of 200 mg.Acute Myocardial Infarction: n patients with definite or suspected acute myocardial infarction, treatment with Cardilock 50 mg I.V. Injection should be initiated as soon as possible after the patient's arrival in the hospital and after eligibility is established. Treatment should begin with the intravenous administration of 5 mg Cardilock 50 mg over 5 minutes followed by another 5 mg intravenous injection 10 minutes later. In patients who tolerate the full intravenous dose (10 mg), Cardilock 50 mg Tablets 50 mg should be initiated 10 minutes after the last intravenous dose followed by another 50 mg oral dose 12 hours later. Thereafter, Cardilock 50 mg can be given orally either 100 mg once daily or 50 mg twice a day for a further 6-9 days or until discharge from the hospital. If bradycardia or hypotension requiring treatment or any other untoward effects occur, Cardilock 50 mg should be discontinued.

Catecholamine-depleting drugs (eg, reserpine) may have an additive effect when given with beta-blocking agents. Patients treated with Cardilock 50 mg plus a catecholamine depletor should therefore be closely observed for evidence of hypotension and/or marked bradycardia which may produce vertigo, syncope, or postural hypotension. Calcium channel blockers may also have an additive effect when given with Cardilock 50 mg. Disopyramide is a Type I antiarrhythmic drug with potent negative inotropic and chronotropic effects. Disopyramide has been associated with severe bradycardia, asystole and heart failure when administered with beta blockers. Amiodarone is an antiarrhythmic agent with negative chronotropic properties that may be additive to those seen with beta blockers. Beta blockers may exacerbate the rebound hypertension which can follow the withdrawal of clonidine. If the two drugs are coadministered, the beta blocker should be withdrawn several days before the gradual withdrawal of clonidine. If replacing clonidine by beta-blocker therapy, the introduction of beta blockers should be delayed for several days after clonidine administration has stopped. Concomitant use of prostaglandin synthase inhibiting drugs, eg, indomethacin, may decrease the hypotensive effects of beta blockers. While taking beta blockers, patients with a history of anaphylactic reaction to a variety of allergens may have a more severe reaction on repeated challenge, either accidental, diagnostic or therapeutic. Such patients may be unresponsive to the usual doses of epinephrine used to treat the allergic reaction. Both digitalis glycosides and beta-blockers slow atrioventricular conduction and decrease heart rate. Concomitant use can increase the risk of bradycardia.

Cardilock 50 mg is contraindicated in- Sinus bradycardia, heart block greater than first degree, cardiogenic shock, and overt cardiac failure. Those patients with a history of hypersensitivity to the Cardilock 50 mg or any of the drug product’s components.

In a series of investigations in the treatment of acute myocardial infarction, bradycardia and hypotension occurred more commonly, as expected for any beta blocker. In addition, a variety of adverse efects has been reported with other beta-adrenergic blocking agents, and may be considered potential adverse efects of Cardilock 50 mg. Hematologic: Agranulocytosis. Allergic: Fever, combined with aching and sore throat, laryngospasm, and respiratory distress. Central Nervous System: Reversible mental depression progressing to catatonia; an acute reversible syndrome characterized by disorientation of time and place; short term memory loss; emotional lability with slightly clouded sensorium; and, decreased performance on neuropsychometrics. Gastrointestinal: Mesenteric arterial thrombosis, ischemic colitis. Miscellaneous: There have been reports of skin rashes and/or dry eyes associated with the use of beta-adrenergic blocking drugs. Discontinuance of the drug should be considered if any such reaction is not otherwise explicable. Patients should be closely monitored following cessation of therapy. Other: Erythematous rash

Pregnancy Category D. Caution should be exercised when Cardilock 50 mg is administered to a nursing woman. Clinically significant bradycardia has been reported in breast-fed infants. Premature infants, or infants with impaired renal function, may be more likely to develop adverse effects.

General: Patients already on a beta blocker must be evaluated carefully before Cardilock 50 mg is administered. Initial and subsequent Cardilock 50 mg dosages can be adjusted downward depending on clinical observations including pulse and blood pressure. Cardilock 50 mg may aggravate peripheral arterial circulatory disorders.Impaired Renal Function: The drug should be used with caution in patients with impaired renal function.Geriatric Use: Hypertension and Angina Pectoris: Due to Coronary Atherosclerosis: Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Acute Myocardial Infarction: Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Evaluation of patients with hypertension or myocardial infarction should always include assessment of renal function.

Overdosage with Cardilock 50 mg has been reported with patients surviving acute doses as high as 5 g. One death was reported in a man who may have taken as much as 10 g acutely. The predominant symptoms reported following Cardilock 50 mg overdose are lethargy, disorder of respiratory drive, wheezing, sinus pause and bradycardia. Additionally, common efects associated with overdosage of any beta-adrenergic blocking agent and which might also be expected in Cardilock 50 mg overdose are congestive heart failure, hypotension, bronchospasm and/or hypoglycemia. Treatment of overdose should be directed to the removal of any unabsorbed drug by induced emesis, gastric lavage, or administration of activated charcoal. Cardilock 50 mg can be removed from the general circulation by hemodialysis. Based on the severity of symptoms, management may require intensive support care and facilities for applying cardiac and respiratory support.

Do not use later than the date of expiry. Keep all medicines out of the reach of children. To be dispensed only on the prescription of a registered physician.

Pediatric use: Safety and effectiveness in pediatric patients have not been established.Renal: Some renal impaired or elderly patients being treated for hypertension may require a lower starting dose of Cardilock 50 mg: 25 mg given as one tablet a day.Hemodialysis: Patients on hemodialysis should be given 25 mg or 50 mg after each dialysis; this should be done under hospital supervision as marked falls in blood pressure can occur.

Elderly Patients or Patients with Renal Impairment: Cardilock 50 mg is excreted by the kidneys; consequently dosage should be adjusted in cases of severe impairment of renal function. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, refecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The following maximum oral dosages are recommended for elderly, renal impaired patients and for patients with renal impairment due to other causes: Creatinine clearance 15-35 ml/min/1.73 m2: Maximum dosage 50 mg daily Creatinine clearance <15 mL/min/1.73 m2: Maximum dosage 25 mg daily Some renal impaired or elderly patients being treated for hypertension may require a lower starting dose of Cardilock 50 mg: 25 mg given as one tablet a day. Patients on hemodialysis should be given 25 mg or 50 mg after each dialysis; this should be done under hospital supervision as marked falls in blood pressure can occur.
