DOSAGE & ADMINISTRATION
5 to 50 mg. 25 to 25 mg, the antihypertensive effects increased with increasing doses of either component. The adverse effects (see WARNINGS ) of bisoprolol are a mixture of dose-dependent phenomena (primarily bradycardia, diarrhea, asthenia, and fatigue) and dose-independent phenomena (eg, occasional rash); those of hydrochlorothiazide are a mixture of dose-dependent phenomena (primarily hypokalemia) and dose-independent phenomena (eg, possibly pancreatitis); the dose- dependent phenomena for each being much more common than the dose-independent phenomena.
The latter consist of those few that are truly idiosyncratic in nature or those that occur with such low frequency that a dose relationship may be difficult to discern. Therapy with a combination of bisoprolol and hydrochlorothiazide will be associated with both sets of dose- independent adverse effects, and to minimize these, it may be appropriate to begin combination therapy only after a patient has failed to achieve the desired effect with monotherapy.
On the other hand, regimens that combine low doses of bisoprolol and hydrochlorothiazide should produce minimal dose-dependent adverse effects, eg, bradycardia, diarrhea, asthenia and fatigue, and minimal dose-dependent adverse metabolic effects, ie, decreases in serum potassium (see CLINICAL PHARMACOLOGY ).
5-20 mg bisoprolol daily may instead be given bisoprolol fumarate and hydrochlorothiazide tablets. Patients whose blood pressures are adequately controlled with 50 mg of hydrochlorothiazide daily, but who experience significant potassium loss with this regimen, may achieve similar blood pressure control without electrolyte disturbance if they are switched to bisoprolol fumarate and hydrochlorothiazide tablets.
25 mg tablet once daily. 25 mg tablets) once daily, as appropriate. Replacement Therapy The combination may be substituted for the titrated individual components. Cessation of Therapy If withdrawal of bisoprolol fumarate and hydrochlorothiazide tablets therapy is planned, it should be achieved gradually over a period of about 2 weeks.
Patients should be carefully observed.
Patients with Renal or Hepatic Impairment:
As noted in the WARNINGS section, caution must be used in dosing/titrating patients with hepatic impairment or renal dysfunction. Since there is no indication that hydrochlorothiazide is dialyzable, and limited data suggest that bisoprolol is not dialyzable, drug replacement is not necessary in patients undergoing dialysis.
ADVERSE REACTIONS
25 mg is well tolerated in most patients. Most adverse effects (AEs) have been mild and transient. In more than 65,000 patients treated worldwide with bisoprolol fumarate, occurrences of bronchospasm have been rare. 25 mg and placebo-treated patients.
25 mg and 144 patients received placebo in two controlled trials. 25 mg was administered for 4 weeks. 25 mg was administered for 12 weeks. 25 mg-treated patients (plus additional selected adverse experiences) are presented in the following table: a) Averages adjusted to combine across studies.
b) Combined across studies. Other adverse experiences that have been reported with the individual components are listed below. Bisoprolol Fumarate In clinical trials worldwide, or in postmarketing experience, a variety of other AEs, in addition to those listed above, have been reported.
While in many cases it is not known whether a causal relationship exists between bisoprolol and these AEs, they are listed to alert the physician to a possible relationship.

WARNINGS
Cardiac Failure In general, beta-blocking agents should be avoided in patients with overt congestive failure. However, in some patients with compensated cardiac failure, it may be necessary to utilize these agents. In such situations, they must be used cautiously.
Patients Without a History of Cardiac Failure Continued depression of the myocardium with beta-blockers can, in some patients, precipitate cardiac failure. At the first signs or symptoms of heart failure, discontinuation of bisoprolol fumarate and hydrochlorothiazide tablets should be considered.
In some cases bisoprolol fumarate and hydrochlorothiazide tablet therapy can be continued while heart failure is treated with other drugs. Abrupt Cessation of Therapy Exacerbations of angina pectoris and, in some instances, myocardial infarction or ventricular arrhythmia, have been observed in patients with coronary artery disease following abrupt cessation of therapy with beta-blockers.
Such patients should, therefore, be cautioned against interruption or discontinuation of therapy without the physician’s advice. Even in patients without overt coronary artery disease, it may be advisable to taper therapy with bisoprolol fumarate and hydrochlorothiazide tablets over approximately 1 week with the patient under careful observation.
If withdrawal symptoms occur, beta-blocking agent therapy should be reinstituted, at least temporarily. Peripheral Vascular Disease Beta-blockers can precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease.
Caution should be exercised in such individuals. Bronchospastic Disease PATIENTS WITH BRONCHOSPASTIC PULMONARY DISEASE SHOULD, IN GENERAL, NOT RECEIVE BETA-BLOCKERS. Because of the relative beta 1 -selectivity of bisoprolol fumarate, bisoprolol fumarate and hydrochlorothiazide tablets may be used with caution in patients with bronchospastic disease who do not respond to, or who cannot tolerate other antihypertensive treatment.
CONTRAINDICATIONS
Bisoprolol fumarate and hydrochlorothiazide tablets are contraindicated in patients in cardiogenic shock, overt cardiac failure (see WARNINGS ), second or third degree AV block, marked sinus bradycardia, anuria, and hypersensitivity to either component of this product or to other sulfonamide-derived drugs.
Not medical advice. Always read the patient information leaflet and follow your prescriber or pharmacist.

Postmarketing Experience Non-melanoma Skin Cancer Hydrochlorothiazide is associated with an increased risk of non-melanoma skin cancer. In a study conducted in the Sentinel System, increased risk was predominantly for squamous cell carcinoma (SCC) and in white patients taking large cumulative doses.
The increased risk for SCC in the overall population was approximately 1 additional case per 16,000 patients per year, and for white patients taking a cumulative dose of ≥50,000 mg the risk increase was approximately 1 additional SCC case for every 6,700 patients per year.
25 mg are less frequent and of smaller magnitude than with HCTZ 25 mg. S. placebo-controlled trials are shown in the following table: a) Combined across studies. b) Patients with normal serum potassium at baseline. c) Mean change from baseline at Week 4.
d) Percentage of patients with abnormality at Week 4. Treatment with both beta blockers and thiazide diuretics is associated with increases in uric acid. 25 mg was smaller than in patients treated with HCTZ 25 mg. 25 mg. Total cholesterol was generally unaffected, but small decreases in HDL cholesterol were noted.
Other laboratory abnormalities that have been reported with the individual components are listed below. Bisoprolol Fumarate In clinical trials, the most frequently reported laboratory change was an increase in serum triglycerides, but this was not a consistent finding.
Sporadic liver test abnormalities have been reported. S. 5% for placebo. No patient had concomitant elevations greater than twice normal. 2%. 9%. 5%. 3%. In many cases these elevations were attributed to underlying disorders, or resolved during continued treatment with bisoprolol fumarate.
Other laboratory changes included small increases in uric acid, creatinine, BUN, serum potassium, glucose, and phosphorus and decreases in WBC and platelets. There have been occasional reports of eosinophilia. These were generally not of clinical importance and rarely resulted in discontinuation of bisoprolol fumarate.
As with other beta-blockers, ANA conversions have also been reported on bisoprolol fumarate. About 15% of patients in long-term studies converted to a positive titer, although about one-third of these patients subsequently reconverted to a negative titer while on continued therapy.
Hydrochlorothiazide Hyperglycemia, glycosuria, hyperuricemia, hypokalemia and other electrolyte imbalances (see PRECAUTIONS ), hyperlipidemia, hypercalcemia, leukopenia, agranulocytosis, thrombocytopenia, aplastic anemia, and hemolytic anemia have been associated with HCTZ therapy.
Since beta 1 -selectivity is not absolute, the lowest possible dose of bisoprolol fumarate and hydrochlorothiazide tablets should be used. A beta 2 agonist (bronchodilator) should be made available. Major Surgery Chronically administered beta-blocking therapy should not be routinely withdrawn prior to major surgery; however, the impaired ability of the heart to respond to reflex adrenergic stimuli may augment the risks of general anesthesia and surgical procedures.
, surgery, not eating regularly, or are vomiting). If severe hypoglycemia occurs, patients should be instructed to seek emergency treatment. Also, latent diabetes mellitus may become manifest and diabetic patients given thiazides may require adjustment of their insulin dose.
Thyrotoxicosis Beta-adrenergic blockade may mask clinical signs of hyperthyroidism, such as tachycardia. Abrupt withdrawal of beta-blockade may be followed by an exacerbation of the symptoms of hyperthyroidism or may precipitate thyroid storm.
Renal Disease Cumulative effects of the thiazides may develop in patients with impaired renal function. In such patients, thiazides may precipitate azotemia. In subjects with creatinine clearance less than 40 mL/min, the plasma half-life of bisoprolol fumarate is increased up to threefold, as compared to healthy subjects.
If progressive renal impairment becomes apparent, bisoprolol fumarate and hydrochlorothiazide tablets should be discontinued (See Pharmacokinetics and Metabolism ). Hepatic Disease Bisoprolol fumarate and hydrochlorothiazide tablets should be used with caution in patients with impaired hepatic function or progressive liver disease.
Thiazides may alter fluid and electrolyte balance, which may precipitate hepatic coma. Also, elimination of bisoprolol fumarate is significantly slower in patients with cirrhosis than in healthy subjects (See Pharmacokinetics and Metabolism ).
Acute Angle-Closure Glaucoma with or without Acute Myopia and Choroidal Effusions Hydrochlorothiazide, a sulfonamide, can cause an idiosyncratic reaction, resulting in acute angle-closure glaucoma and elevated intraocular pressure with or without a noticeable acute myopic shift and/or choroidal effusions.
Symptoms may include acute onset of decreased visual acuity or ocular pain and typically occur within hours to weeks of drug initiation. Untreated, the acute angle-closure glaucoma may result in permanent visual field loss. The primary treatment is to discontinue hydrochlorothiazide as rapidly as possible.
Prompt medical or surgical treatments may need to be considered if the intraocular pressure remains uncontrolled. Risk factors for developing acute angle-closure glaucoma may include a history of sulfonamide or penicillin allergy.
