What is Tensyn SR?
Tensyn SR is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure may reduce the risk of stroke and heart attacks.
Tensyn SR is also used to treat severe chest pain (angina), migraine headaches, or hypertrophic subaortic stenosis (thickened heart muscle).
Tensyn SR may also be used to treat irregular heartbeats, tremors, or pheochromocytoma (adrenal gland tumor). It may also be used to reduce the risk of death in patients who have heart attacks.
Tensyn SR oral solution is used to treat proliferating infantile hemangioma.
Tensyn SR is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart.
Tensyn SR is available only with your doctor's prescription.
Tensyn SR indications
Hypertension
Tensyn SR is indicated in the management of hypertension. It may be used alone or used in combination with other antihypertensive agents, particularly a thiazide diuretic. Tensyn SR is not indicated in the management of hypertensive emergencies.
Angina Pectoris Due to Coronary Atherosclerosis
Tensyn SR is indicated to decrease angina frequency and increase exercise tolerance in patients with angina pectoris.
Atrial Fibrillation
Tensyn SR is indicated to control ventricular rate in patients with atrial fibrillation and a rapid ventricular response.
Myocardial Infarction
Tensyn SR is indicated to reduce cardiovascular mortality in patients who have survived the acute phase of myocardial infarction and are clinically stable.
Migraine
Tensyn SR is indicated for the prophylaxis of common migraine headache. The efficacy of Tensyn SR in the treatment of a migraine attack that has started has not been established, and Tensyn SR is not indicated for such use.
Essential Tremor
Tensyn SR is indicated in the management of familial or hereditary essential tremor. Familial or essential tremor consists of involuntary, rhythmic, oscillatory movements, usually limited to the upper limbs. It is absent at rest, but occurs when the limb is held in a fixed posture or position against gravity and during active movement. Tensyn SR causes a reduction in the tremor amplitude, but not in the tremor frequency. Tensyn SR is not indicated for the treatment of tremor associated with Parkinsonism.
Hypertrophic Subaortic Stenosis
Tensyn SR improves NYHA functional class in symptomatic patients with hypertrophic subaortic stenosis.
Pheochromocytoma
Tensyn SR is indicated as an adjunct to alpha-adrenergic blockade to control blood pressure and reduce symptoms of catecholamine-secreting tumors.
How should I use Tensyn SR?
Use Tensyn SR solution as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Tensyn SR solution comes with extra patient information sheets called a Medication Guide and Instructions for Use. Read them carefully. Read them again each time you get Tensyn SR solution refilled.
- Do NOT shake Tensyn SR solution before use.
- Use the syringe that comes with Tensyn SR solution to measure the dose. Ask the pharmacist for help if you are unsure of how to measure the dose.
- Give Tensyn SR solution right into your child's mouth. If needed, Tensyn SR solution may be mixed in a small amount of milk or fruit juice and given in a baby's bottle.
- Give Tensyn SR solution with or right after a feeding.
- Give doses of Tensyn SR solution at least 9 hours apart.
- The dose of Tensyn SR solution may need to be changed as your child's weight changes. Have your child's weight checked often. Talk with the doctor before changing your child's dose.
- Give Tensyn SR solution on a regular schedule to get the most benefit from it. Giving Tensyn SR solution at the same time each day will help you remember to give it.
- If your child spits up a dose or if you are not sure your child got all of the medicine, do not give another dose. Wait until the next scheduled dose.
- If you miss giving your child a dose of Tensyn SR solution, give it as soon as possible. If it is almost time for the next dose, skip giving the missed dose and go back to your child's regular dosing schedule. Do not give 2 doses at once.
Ask your health care provider any questions you may have about how to use Tensyn SR solution.

What other drugs will affect Tensyn SR?
Patients receiving catecholamine-depleting drugs such as reserpine should be closely observed if Beta-Tensyn SR HCl is administered. The added catecholamine-blocking action may produce an excessive reduction of resting sympathetic nervous activity, which may result in hypotension, marked bradycardia, vertigo, syncopal attacks, or orthostatic hypotension.
Caution should be exercised when patients receiving a beta blocker are administered a calcium-channel blocking drug, especially intravenous verapamil, for both agents may depress myocardial contractility or atrioventricular conduction. On rare occasions, the concomitant intravenous use of a beta blocker and verapamil has resulted in serious adverse reactions, especially in patients with severe cardiomyopathy, congestive heart failure, or recent myocardial infarction.
Blunting of the antihypertensive effect of beta-adrenoceptor blocking agents by nonsteroidal anti-inflammatory drugs has been reported.
Hypotension and cardiac arrest have been reported with the concomitant use of Tensyn SR and haloperidol.
Aluminum hydroxide gel: Greatly reduces intestinal absorption of Tensyn SR.
Ethanol: Slows the rate of absorption of Tensyn SR.
Phenytoin, phenobarbitone: and rifampin accelerate Tensyn SR clearance.
Chlorpromazine: When used concomitantly with Tensyn SR, results in increased plasma levels of both drugs.
Antipyrine: and lidocaine have reduced clearance when used concomitantly with Tensyn SR.
Thyroxine: May result in a lower than expected T3 concentration when used concomitantly with Tensyn SR.
Cimetidine Decreases the hepatic metabolism of Tensyn SR, delaying elimination and incre:asing blood levels.
Theophylline: Clearance is reduced when used concomitantly with Tensyn SR.

What are the possible side effects of Tensyn SR?
The following serious adverse reactions are discussed in greater detail in other sections of the labeling:
- Hypoglycemia and related events, like hypoglycemic seizure.
- Bronchospasm.
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug may not reflect the rates observed in clinical practice.
Clinical Trials Experience with Tensyn SR in Infants with proliferating infantile hemangioma
In clinical trials for proliferating infantile hemangioma, the most frequently reported adverse reactions ( > 10%) in infants treated with Tensyn SR were sleep disorders, aggravated respiratory tract infections such as bronchitis and bronchiolitis associated with cough and fever, diarrhea, and vomiting. Adverse reactions led to treatment discontinuation in fewer than 2% of treated patients.
Overall, 479 patients in the pooled safety population were exposed to study drug in the clinical study program (456 in placebo-controlled trials). A total of 424 patients were treated with Tensyn SR at doses 1.2 mg/kg/day or 3.4 mg/kg/day for 3 or 6 months. Of these, 63% of patients were aged 91-150 days and 37% were aged 35-90 days at randomization.
The following table lists according to the dosage the most common adverse reactions (treatment-emergent adverse events with an incidence at least 3% greater on one of the two doses than on placebo).
Table 2: Treatment-emergent adverse events occurring at least 3% more often on Tensyn SR than on placebo.
| Reaction | Placebo N=236 | Tensyn SR 1.2 mg/kg/day N=200 | Tensyn SR 3.4 mg/kg/day N=224 |
| Sleep disorder | 5.90% | 17.50% | 16.10% |
| Bronchitis | 4.7 | 8 | 13.4 |
| Peripheral coldness | 0.4 | 8 | 6.7 |
| Agitation | 2.1 | 8.5 | 4.5 |
| Diarrhea | 1.3 | 4.5 | 6.3 |
| Somnolence | 0.4 | 5 | 0.9 |
| Nightmare | 1.7 | 2 | 6.3 |
| Irritability | 1.3 | 5.5 | 1.3 |
| Decreased appetite | 0.4 | 2.5 | 3.6 |
| Abdominal pain | 0.4 | 3.5 | 0.4 |
The following adverse events have been observed during clinical studies, with an incidence of less than 1%:
Cardiac disorders: Second degree atrioventricular heart block, in a patient with underlying conduction disorder, required definitive treatment discontinuation.
Skin and subcutaneous tissue disorders: Urticaria, alopecia
Investigations: Decreased blood glucose, decreased heart rate
Compassionate Use Program
More than 600 infants received Tensyn SR in a compassionate use program (CUP). Mean age at treatment initiation was 3.6 months. Mean dose of Tensyn SR was 2.2 mg/kg/day and mean treatment duration was 7.1 months.
The adverse reactions reported in the CUP were similar to the ADRs observed during clinical trials but some were more severe.
Postmarketing Experience
The following adverse reactions have been identified during post-approval use of Tensyn SR. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
These adverse reactions are as follows:
Blood and lymphatic system disorders: Agranulocytosis
Psychiatric disorders: Hallucination
Skin and subcutaneous tissues disorders: Purpura
