Tenormin is a prescription drug which was first approved by the FDA in 1981. It is rather useful in such conditions as hypertension or angina and helps to lower the risk of cardiovascular strokes and myocardial infractions. During Tenormin therapy it’s necessary to check the state of a patient on a regular basis to achieve the desired blood pressure level.
Mechanism of Action
The action of the medicine is determined by its active agent, atenolol. Tenormin belongs to beta-blockers, that is the agent which binds beta one adrenergic receptors selectively in the heart and vascular smooth muscles. Due to the blockage of beta one receptors, sympathetic stimulation is inhibited, which provides a relaxing effect on heart rates, pressure and cardiac output. However, it’s rather important to stick to the prescribed dosage as a huge amount of atenolol in the body may result in beta 2 blockage.
There are some people who mustn’t use beta-blockers, including Tenormin, because of the following conditions:
Allergy to any components, both active and inactive;
Heart block of second or third degree;
Sick sinus syndrome;
Peripheral arterial circulatory disorder;
When using Tenormin, it’s necessary to follow some rules to make the therapy safe and effective for you:
1. If you are going to have surgery, and beta-blockers administration must be stopped, it’s to be done at least 24 hours before the surgery.
2. If there is a decision to stop the therapy with Tenormin, it’s forbidden to withdraw abruptly.
3. Impaired renal function might influence the dosage of the medicine to make it safe for a patient.
4. Those patients who suffer from diabetes must take Tenormin with caution, as it may mask tachycardia which is a symptom of hypoglycemia.
5. Breastfeeding women should take the medicine only in case there is a reasonable necessity for taking Tenormin.
