What is Co-Tenidone?

Co-Tenidone tablets derive from a group of medicines called beta-blockers and diuretics, that is, it works on your heart and circulatory system. It is used in the treatment of high blood pressure, angina, cardiac arrhythmias (to achieve a regular and adequate heartbeat rhythm), and acute myocardial infarction (to protect the heart during and after the infarction).

How does it work?

This high blood pressure medication works because it combines the antihypertensive activity of two agents, ß-blocker (atenolol) and a diuretic (chlorthalidone). Atenolol is a selective beta1-blocker beta (that is, it acts preferentially on the beta1-adrenergic receptors of the heart. Chlorthalidone is a monosulfonamil diuretic that increases the excretion of sodium and chlorine. Natriuresis is accompanied by some loss of potassium. Unknown fully the mechanism by which chlorthalidone reduces blood pressure, but may be related to excretion and redistribution of body sodium.

What are the benefits of taking it?

The multiple Co-Tenidone uses include reducing the heart's oxygen needs by reducing heart rate, blood pressure, and the force exerted by the heart. They increase blood flow to the coronary arteries, which is why they reduce the symptoms of angina pectoris. This is thanks to its beta-blockers and its diuretic.

How do I use it and its dosage?

Always take Co-Tenidone tablets exactly as directed by your doctor. Ask your doctor or pharmacist if you have doubts. Your doctor decides the appropriate dose, the frequency of your condition, and whether you are taking other medications. It is very important to continue taking Co-tenidone tablets for the time recommended by the doctor. Co-tenidone tablets should be swallowed whole with a little water.

Adults: Essential hypertension (high blood pressure): The starting dose is 50 mg per day (half a tablet).

The maximum effect occurs after 1-2 weeks of treatment. If the response is not enough, you can increase the dose to 100 mg. Efficacy generally does not increase if this dose is exceeded. Blood pressure can be further reduced by combining Co-Tenidone tablets with other antihypertensive medications.

Angina pectoris: usually starts with a dose of 50 mg (half tablet) per day, but the effective dose is generally 100 mg in a single oral dose or two doses of 50 mg per day.

Cardiac arrhythmias: After controlling arrhythmias with intravenous treatment, the appropriate oral maintenance dose is 50-100 mg/day, administered in a single dose. Early intervention after acute myocardial infarction: in patients in whom atenolol treatment is indicated, it will start intravenously and then continue orally, with 50 or 100 mg daily. If you experience bradycardia (decreased heart rate) and/or hypotension (decreased blood pressure) that requires treatment or produce other unwanted effects, you should discontinue this treatment.

Late intervention after acute myocardial infarction: if several days have elapsed since acute myocardial infarction, an oral dose of atenolol of 100 mg/day is recommended as long-term maintenance.

Use in children:

The safety of atenolol in children has not been established and therefore it should not be used in children.

Use in the elderly:

The dose may need to be reduced, especially if kidney function is impaired.

Patients with kidney failure (failure of adequate kidney function): It will be necessary to adjust the determined dose of its severity:

Mild, no dosage modification necessary.

moderate, it is recommended to administer a maximum of 50 mg per day.

severe, it is recommended to administer 50 mg every other day or 100 mg every 4 days.
