Bisoprololfumaraat/Hydrochloorthiazide Mylan

Uses

Bisoprolol is used for the treatment of hypertension, angina and heart failure. It may be used alone or in combination with other antihypertensive agents.

Bisoprololfumaraat/Hydrochloorthiazide Mylan is also used to associated treatment for these conditions: Atrial Fibrillation, Cardiovascular Events, Chronic Stable Angina Pectoris, Heart Failure, High Blood Pressure (Hypertension), Mild Hypertension, Premature Ventricular Contraction (PVC), Supraventricular Arrhythmias, Moderate Hypertension, Perioperative arrhythmia

How Bisoprololfumaraat/Hydrochloorthiazide Mylan works

Though the mechanism of action of bisoprolol has not been fully elucidated in hypertension, it is thought that therapeutic effects are achieved through the antagonism of β-1adrenoceptors to result in lower cardiac output. Bisoprolol is a competitive, cardioselective β1-adrenergic antagonist. When β1-receptors (located mainly in the heart) are activated by adrenergic neurotransmitters such as epinephrine, both the blood pressure and heart rate increase, leading to greater cardiovascular work, increasing the demand for oxygen. Bisoprolol reduces cardiac workload by decreasing contractility and the need for oxygen through competitive inhibition of β1-adrenergic receptors.

Bisoprolol is also thought to reduce the output of renin in the kidneys, which normally increases blood pressure. Additionally, some central nervous system effects of bisoprolol may include diminishing sympathetic nervous system output from the brain, decreasing blood pressure and heart rate.

Dosage

Bisoprololfumaraat/Hydrochloorthiazide Mylan dosage

The usual starting dose is 5 mg once daily. In some patients, 2.5 mg may be an appropriate starting dose. If the antihypertensive effect of 5 mg is inadequate, the dose may be increased to 10 mg and then, if necessary, to 20 mg once daily.

For heart failure: Initially 1.25 mg once daily (in the morning) for 1 week then, if well tolerated, increased to 2.5 mg once daily for 1 week, then 3.75 mg once daily for 1 week, then 5 mg once daily for 4 weeks, then 7.5 mg once daily for 4 weeks, then 10 mg once daily; max. 10 mg daily.

Side Effects

Diarrhoea, dizziness, drowsiness, fatigue, headache, lightheadedness, nausea, sleeplessness, unusual tiredness, weakness, Severe allergic reactions (rash, hives, itching, difficulty breathing, tightness in the chest, swelling of the mouth, face, lips, or tongue), chest pain, difficulty breathing, lightheadedness or dizziness when rising from a lying or sitting position, very slow heartbeat.

Toxicity

LD50 information Oral LD50 of bisoprolol in the mouse was 730 mg/kg.

Overdose information

Signs of a β-blocker overdose include cardiovascular symptoms such as hypotension, congestive heart failure, and bradycardia. Other symptoms such as bronchospasm, and hypoglycemia may occur. If an overdose occurs with bisoprolol, supportive treatment should be initiated. Glucagon has been shown to be beneficial in bradycardia and hypotension associated with beta-blocker overdosage. Hypoglycemia may be managed by administering IV glucose. Monitor the patient and administer atropine in cases of bradycardia, pressors and fluids in the case of hypotension, and conventional heart failure therapy if heart failure occurs. If heart block occurs, the patient must be closely monitored and isoproterenol infusion or transvenous cardiac pacemaker insertion should take place. For the management of overdose-related bronchospasm, administer bronchodilators with or without IV aminophylline. Limited research suggests that bisoprolol fumarate is not removed adequately by hemodialysis sessions.

Precaution

Bisoprolol Fumarate must be used with caution in:

• Bronchospasm (bronchial asthma, obstructive airways diseases)
• Diabetes Mellitus with large fluctuations in blood glucose values; symptoms of hypoglycemia can be masked
• Strict fasting
• Ongoing desensitization therapy
• First degree AV block
• Prinzmetal's angina
• Peripheral arterial occlusive disease (intensification of complaints might happen especially during the start of therapy)
• General anesthesia

Interaction

Bisoprolol should not be combined with other beta-blocking agents. Patients receiving catecholamine-depleting drugs, should be closely monitored, because the added beta-adrenergic blocking action of Bisoprolol may produce excessive reduction of sympathetic activity.In patients receiving concurrent therapy with clonidine, if therapy is to be discontinued, it is suggested that Bisoprolol be discontinued for several days before the withdrawal of clonidine. Bisoprolol should be used with care when myocardial depressants or inhibitors of AV conduction, such as certain calcium antagonists or antiarrhythmic agents are used concurrently.Other Alfred Angelo wedding dress collection comes in mermaid dress cut.

However, initial dose modification is generally not necessary.

Volume of Distribution

The volume of distribution of bisoprolol is 3.5 L/kg. The mean volume of distribution was found to be 230 L/kg in heart failure patients, which was similar to the volume of distribution in healthy patients. Bisoprolol is known to cross the placenta.

Elimination Route

Bisoprolol is well absorbed in the gastrointestinal tract. The AUC is 642.87 g.hr/mL and bioavailability of bisoprolol is about 90% due to the minimal first pass effects. Absorption is unaffected by food intake. Peak plasma concentrations of bisoprolol are attained within 2-4 hours and steady-state concentrations are achieved within 5 days of administration. In a pharmacokinetic study, the mean peak concentration of bisoprolol was 52 micrograms/L. Cmax at steady state concentrations of bisoprolol is 64±21 ng/ml administered at 10 mg daily.

Half Life

A pharmacokinetic study in 12 healthy individuals determined the mean plasma half-life of bisoprolol to be 10-12 hours. Another study comprised of healthy patients determined the elimination half-life to be approximately 10 hours. Renal impairment increased the half-life to 18.5 hours.

Clearance

Total body clearance in healthy patients was determined to be 14.2 L/h. In patients with renal impairment, clearance was reduced to 7.8 L/h. Hepatic dysfunction also reduced the clearance of bisoprolol.

Elimination Route

Bisoprolol is eliminated equally by both renal and hepatic pathways. About 50% of an oral dose is excreted unchanged in the urine with the remainder of the dose excreted as inactive bisoprolol metabolites. Under 2% of the ingested dose is found to be excreted in the feces.

Pregnancy & Breastfeeding use

Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Bisoprolol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.Nursing Mothers:Small amounts of bisoprolol fumarate (< 2% of the dose) have been detected in the milk of lactating rats. It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk caution should be exercised when bisoprolol fumarate is administered to nursing women.

Contraindication

Bisoprolol is contraindicated in patients with cardiogenic shock, overt cardiac failure, second or third degree AV block, and marked sinus bradycardia.

Special Warning

Pediatric Patients: There is no pediatric experience with Bisoprolol.

Geriatric Patients: It is not necessary to adjust the dose in the elderly, unless there is also significant renal or hepatic dysfunction.

Renal impairment: Reduce dose if eGFR less than 20 ml/ minute/ 1.73 m2 (max. 10 mg daily).

Hepatic impairment: Maximum 10 mg daily in severe impairment (hepatitis or cirrhosis).

Acute Overdose

The most common signs expected with overdosage of a beta-blocker are bradycardia, hypotension, congestive heart failure, bronchospasm, and hypoglycemia. To date, a few cases of overdose (maximum: 2000 mg) with bisoprolol have been reported. Bradycardia and/or hypotension were noted. Sympathomimetic agents were given in some cases, and all patients recovered. In general, if overdose occurs, bisoprolol therapy should be stopped and supportive and symptomatic treatment should be provided. Limited data suggest that bisoprolol fumarate is not dialyzable. Based on the expected pharmacologic actions and recommendations for other beta-blockers, the following general measures should be considered when clinically warranted.

Storage Condition

Keep out of the reach of children. Protect from light and moisture, keep in a cool and dry place.
