GLUCOPHAGE (metformin HCl) Tablets
[November 6, 1997: Bristol-Myers Squibb]

CONTRAINDICATIONS:
Addition of text as new #2 -

"2. Congestive heart failure requiring pharmacologic treatment."

Current #2, #3, & #4 renumbered as #3, #4, & #5.

WARNINGS:
Boxed Warning - Lactic Acidosis: Second paragraph revised (new text in italics) -

The reported incidence of lactic acidosis in patients receiving metformin hydrochloride is very low (approximately 0.03 cases/1,000 patient-years, with approximately 0.015 fatal cases/1,000 patient-years). Reported cases have occurred primarily in diabetic patients with significant renal insufficiency, including both intrinsic renal disease and renal hypoperfusion, often in the setting of multiple concomitant medical/surgical problems and multiple concomitant medications. Patients with congestive heart failure requiring pharmacologic management, in particular those with unstable or acute congestive heart failure who are at risk of hypoperfusion and hypoxemia, are at increased risk of lactic acidosis. The risk of lactic acidosis increases with the degree of renal dysfunction and the patient's age. The risk of lactic acidosis may, therefore, be significantly decreased by regular monitoring of renal function in patients taking Glucophage and by use of the minimum effective dose of Glucophage. In particular, treatment of the elderly should be accompanied by careful monitoring of renal function. Glucophage treatment should not be initiated in patients > or = 80 years of age unless measurement of creatinine clearance demonstrates that renal function is not reduced, as these patients are more susceptible to developing lactic acidosis. In addition, Glucophage should be promptly withheld in the presence of any condition associated with hypoxemia, ["or" deleted] dehydration, or sepsis. Because impaired hepatic function may significantly limit the ability to clear lactate, Glucophage should generally be avoided in patients with clinical or laboratory evidence of hepatic disease. Patients should be cautioned against excessive alcohol intake, either acute or chronic, when taking Glucophage, since alcohol potentiates the effects of metformin hydrochloride on lactate metabolism. In addition, Glucophage should be temporarily discontinued prior to any intravascular radiocontrast study and for any surgical procedure (see also PRECAUTIONS)."

PRECAUTIONS:
General: Monitoring of renal function: First paragraph, addition of new last sentence -

"For patients > or = 80 years of age, see WARNINGS."

Geriatric Use: Last sentence revised (new text in italics) -

"Generally, elderly patients should not be titrated to the maximum dose of Glucophage (see also WARNINGS and DOSAGE AND ADMINISTRATION)."

DOSAGE AND ADMINISTRATION:
Specific Patient Populations: New text added as new second to last paragraph -

"Monitoring of renal function is necessary to aid in prevention of lactic acidosis, particularly in the elderly. (See WARNINGS.)"

PATIENT INFORMATION ABOUT GLUCOPHAGE (metformin hydrochloride tablets):
Question #10 revised (new text in italics) -

"Q10. Are there other risk factors for lactic acidosis?
Your risk of developing lactic acidosis from taking Glucophage is very low as long as your kidneys and liver are healthy. However, some factors can increase your risk because they can affect kidney and liver function. You should discuss your risk with your physician. You should not take Glucophage if:

INDERAL (propranolol HCl) Tablets & Injection
and
INDERAL LA (propranolol HCl) Long-Acting Capsules
[November 7, 1997: Wyeth-Ayerst]

WARNINGS:
Diabetes and Hypoglycemia: Text deleted and replaced with -

"Beta-adrenergic blockade may prevent the appearance of certain premonitory signs and symptoms (pulse rate and pressure changes) of acute hypoglycemia in labile insulin-dependent diabetes. In these patients, it may be more difficult to adjust the dosage of insulin. Hypoglycemic attacks may be accompanied by a precipitous elevation of blood pressure in patients on propranolol.

"Propranolol therapy, particularly in infants and children, diabetic or not, has been associated with hypoglycemia especially during fasting as in preparation for surgery. Hypoglycemia also has been found after this type of drug therapy and prolonged physical exertion and has occurred in renal insufficiency, both during dialysis and sporadically, in patients on propranolol."

PRECAUTIONS:
General: Text added at end of subsection -

Risk of anaphylactic reaction. While taking beta blockers, patients with a history of severe anaphylactic reaction to a variety of allergens may be more reactive to repeated challenge, either accidental, diagnostic, or therapeutic. Such patients may be unresponsive to the usual doses of epinephrine used to treat allergic reaction."

Carcinogenesis, Mutagenesis, Impairment of Fertility: Text deleted and replaced with -

"In dietary administration studies in which mice and rats were treaed with propranolol for up to 18 months at doses of up to 150 mg/kg/day, there was no evidence of drug-related tumorigenesis. In a study in which both male and female rats were exposed to propranolol in their diets at concentrations of up to 0.05%, from 60 days prior to mating and throughout pregnancy and lactation for two generations, there were no effects on fertility. Based on differing results from Ames Tests performed by different laboratories, there is equivocal evidence for a genotoxic effect of propranolol in bacteria (S. typhimurium strain TA 1538)."

Pregnancy: Pregnancy Category C: First paragraph deleted and replaced with -

"In a series of reproductive and developmental toxicology studies, propranolol was given to rats by gavage or in the diet throughout pregnancy and lactation. At doses of 150 mg/kg/day (> 10 times the maximum recommended human daily dose of propranolol on a body weight basis), but not at doses of 80 mg/kg/day, treatment was associated with embryotoxicity (reduced litter size and increased resorption sites) as well as neonatal toxicity (deaths). Propranolol also was administered (in the feed) to rabbits (throughout pregnancy and lactation) at doses as high as 150 mg/kg/day (> 15 times the maximum recommended daily human dose). No evidence of embryo or neonatal toxicity was noted."

Risk of anaphylactic reaction. While taking beta blockers, patients with a history of severe anaphylactic reaction to a variety of allergens may be more reactive to repeated challenge, either accidental, diagnostic, or therapeutic. Such patients may be unresponsive to the usual doses of epinephrine used to treat allergic reaction."

Carcinogenesis, Mutagenesis, Impairment of Fertility: Text deleted and replaced with -

"Combinations of propranolol and hydrochlorothiazide have not been evaluated for carcinogenic or mutagenic potential or for potential to adversely affect fertility.

"Propranolol hydrochloride (Inderal): In dietary administration studies in which mice and rats were treated with propranolol for up to 18 months at doses of up to 150 mg/kg/day, there was no evidence of drug-related tumorigenesis. In a study in which both male and female rats were exposed to propranolol in their diets at concentrations of up to 0.05%, from 60 days prior to mating and throughout pregnancy and lactation for two generations, there were no effects on fertility. Based on differing results from Ames Tests performed by different laboratories, there is equivocal evidence for a genotoxic effect of propranolol in bacteria (S. typhimurium strain TA 1538).

"Hydrochlorothiazide: Two year feeding studies in mice and rats conducted under the auspices of the National Toxicology Program (NTP) uncovered no evidence of a carcinogenic potential of hydrochlorothiazide in female mice (at doses of up to approximately 600 mg/kg/day) or in male and female rats (at doses of up to approximately 100 mg/kg/day). The NTP, however, found equivocal evidence for hepatocarcinogenicity in male mice.

"Hydrochlorothiazide was not genotoxic in vitro in the Ames bacterial mutagen assay (S. typhimurium strains TA 98, TA 100, TA 1535, TA1537 and TA 1538) or in the Chinese Hamster Ovary (CHO) test for chromosomal aberrations. Nor was it genotoxic in vivo in assays using mouse germinal cell chromosomes, Chinese hamster bone marrow chromosomes, and the Drosophila sex-linked recessive lethal trait gene. Positive test results were obtained in the in vitro CHO Sister Chromatid Exchange (clastogenicity), Mouse Lymphoma Cell (mutagenicity) and Aspergillus nidulans non-disjunction assays.

"Hydrochlorothiazide had no adverse effects on the fertility of mice and rats of either sex in studies wherein these species were exposed, via their diet, to doses of up to 100 mg/kg and 4 mg/kg, respectively, prior to mating and throughout gestation."

Pregnancy: Pregnancy Category C: Text deleted and replaced with -

"Combinations of propranolol and hydrochlorothiazide have not been evaluated for effects on pregnancy in animals. Nor are there adequate and well-controlled studies of propranolol, hydrochlorothiazide, or Inderide in pregnant women. Inderide should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

"Propranolol hydrochloride (Inderal): In a series of reproduction and developmental toxicology studies, propranolol was given to rats by gavage or in the diet throughout pregnancy and lactation. At doses of 150 mg/kg/day (> 30 times the dose of propranolol contained in the maximum recommended human daily dose of Inderide), but not at doses of 80 mg/kg/day, treatment was associated with embryotoxicity (reduced litter size and increased resorption sites) as well as neonatal toxicity (deaths).

"Propranolol was also administered (in the feed) to rabbits (throughout pregnancy and lactation) at doses as high as 150 mg/kg/day (> 45 times the dose of propranolol contained in the maximum recommended daily human dose of Inderide). No evidence of embryo or neonatal toxicity was noted. Intrauterine growth retardation has been reported in human neonates whose mothers received propranolol during pregnancy. Neonates whose mothers are receiving propranolol at parturition have exhibited bradycardia, hypoglycemia and respiratory depression. Adequate facilities for monitoring these infants at birth should be available.

"Hydrochlorothiazide: Studies in which hydrochlorothiazide was orally administered to pregnancy mice and rats at doses of up to 3000 and 1000 mg/kg/day, respectively, provided no evidence of harm to the fetus.

"Thiazides cross the placental barrier and appear in cord blood. The use of thiazides in pregnant women requires that the anticipated benefit be weighed against possible hazards to the fetus. These hazards include fetal or neonatal jaundice, thrombocytopenia, and possibly other adverse reactions that have occurred in the adult."

DOSAGE AND ADMINISTRATION:
Second sentence revised (new text in italics) -

"Hydrochlorothiazide can be given at doses of ["25 to 100" deleted] 12.5 to 50 mg per day when used alone."

Carcinogenesis, Mutagenesis, Impairment of Fertility: Text deleted and replaced with -

"No significant change in tumor incidence or type was observed following two years of oral administration of apraclonidine HCl to rats at dosages of 1 and 0.6 mg/kg/day, up to 50 and 30 times, respectively, the maximum dose recommended for human topical ocular use.

"Apraclonidine HCl was not mutagenic in a series of in vitro mutagenicity assays, including the Ames test, a mouse lymphoma forward mutation assay, a chromosome aberration assay in cultured Chinese hamster ovary (CHO) cells, a sister chromatid exchange assay in CHO cells, and a cell transformation assay. An in vivo mouse micronucleous assay conducted with apraclonidine HCl also provided no evidence of mutagenicity. Reproduction and fertility studies in rats showed no adverse effect on male or female fertility at a dose of 0.5 mg/kg (25 times the maximum recommended human dose)."

Pregnancy: Pregnancy Category C: Text deleted and replaced with -

"Apraclonidine HCl has been shown to have an embryocidal effect in rabbits when given in an oral dose of 3 mg/kg (150 times the maximum recommended human dose). Dose related maternal toxicity was observed in pregnant rats at 0.3 mg/kg (15 times the maximum recommended human dose). There are no adequate and well controlled studies in pregnant women. Iopidine 1% Ophthalmic Solution should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus."

[Other changes not reflected in 1998 PDR: Aug97

WARNINGS: (new section)
"Hepatic: Rare cases of severe idiosyncratic hepatocellular injury have been reported during marketed use (See ADVERSE REACTIONS, Postintroduction Reports). The hepatic injury is usually reversible, but very rare cases of hepatic failure, including death, have been reported. Injury has occurred after both short- and long-term troglitazone treatment.

"During all clinical studies in North America, a total of 48 of 2510 (1.9%) Rezulin-treated patients and 3 of 475 (0.6%) placebo-treated patients had ALT levels greater than 3 times the upper limit of normal. Twenty of the Rezulin-treated and one of the placebo-treated patients were withdrawn from treatment. Two of the 20 Rezulin-treated patients developed reversible jaundice; one of these patients had a liver biopsy which was consistent with an idiosyncratic drug reaction. An additional Rezulin-treated patient had a liver biopsy which was also consistent with an idiosyncratic drug reaction. (See ADVERSE REACTIONS, Laboratory Abnormalities).

"It is recommended that serum transaminase levels be checked within the first one to two months and then every three months during the first year of troglitazone therapy, and periodically thereafter. Liver function tests also should be obtained for patients at the first symptoms suggestive of hepatic dysfunction, e.g., nausea, vomiting, abdominal pain, fatigue, anorexia, dark urine. Rezulin should be discontinued if the patient has jaundice or laboratory measurements suggest liver injury (e.g., ALT > 3 times the upper limit of normal)."

PRECAUTIONS:
General: Paragraph on Hepatic moved to "WARNINGS, Hepatic" as second paragraph - see above.

Information for Patients: Addition of new third paragraph -

"Patients who develop nausea, vomiting, abdominal pain, fatigue, anorexia, dark urine or other symptoms suggestive of hepatic dysfunction or jaundice should immediately report these signs or symptoms to their physician."

SEREVENT (salmeterol xinafoate) Inhalation Aerosol
[November 26, 1997: Glaxo Wellcome]

CLINICAL PHARMACOLOGY:
Pharmacology and Clinical Trials: Third paragraph revised (new text in italics) -

"["Beta-agonists and methylxanthines administered concurrently" deleted] Studies in laboratory animals (minipigs, rodents, and dogs) ["cause" deleted] have demonstrated the occurrence of cardiac arrhythmias and sudden death (with histologic evidence of myocardial necrosis) when beta-agonists and methylxanthines are administered concurrently. ["Whether" deleted] The clinical significance of these findings ["are relevant to humans" deleted] is ["not known" deleted] unknown."

INDICATIONS AND USAGE:
First paragraph revised (new text in italics) -

"Serevent Inhalation Aerosol is indicated for long-term, twice-daily (morning and evening) administration in the maintenance treatment of asthma and in the prevention of bronchospasm in patients 12 years of age and older with reversible obstructive airway disease, including patients with symptoms of nocturnal asthma, who require ["regular" deleted] daily treatment with inhaled short-acting beta2-agonists. It should not be used in patients whose asthma can be managed by occasional use of short-acting, inhaled beta2-agonists."

WARNINGS:
6. Paradoxical Bronchospasm: Subsection revised (new text in italics) -

["As with other inhaled asthma medications," deleted] Serevent Inhalation Aerosol can produce paradoxical bronchospasm, which ["can" deleted] may be life threatening ["has been reported following the use of Serevent Inhalation Aerosol" deleted]. If ["it" deleted] paradoxical bronchospasm occurs, ["treatment with" deleted] Serevent Inhalation Aerosol should be discontinued immediately and alternative therapy instituted. It should be recognized that paradoxical bronchospasm, when associated with inhaled formulations, frequently occurs with the first use of a new canister or vial."

8. Upper Airway Symptoms: Subsection revised (new text in italics) -

"Symptoms of laryngeal spasm, irritation, or swelling, such as stridor and choking have been reported rarely in patients receiving Serevent Inhalation Aerosol.

"Serevent Inhalation Aerosol, like all other beta-adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms. Although such effects are uncommon after administration of Serevent Inhalation Aerosol at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the T wave, prolongation of the QTc interval, and ST segment depression. The clinical significance of these findings is unknown. Therefore, Serevent Inhalation Aerosol, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insuffiency, cardiac arrhythmias, and hypertension."

PRECAUTIONS:
General: 3. Metabolic Effects: First paragraph revised (new text in italics) -

Doses of the related beta2-adrenoceptor agonist albuterol, when administered intravenously, have been reported to aggravate preexisting diabets mellitus and ketoacidosis. No effects on glucose have been seen with Serevent Inhalation Aerosol at recommended doses. ["Administration of beta2-adrenoceptor agonists" deleted] Beta-adrenergic agonist medications may ["cause a decrease in serum potassium" deleted] produce significant hypokalemia in some patients, possibly through intracellular shunting, which has the potential to ["increase the likelihood of arrhythmias" deleted] produce adverse cardiovascular effects. The decrease is usually transient, not requiring supplementation."

Information for Patients: #2: Revised (new text in italics) -

"The action of Serevent Inhalation Aerosol may last up to 12 hours or longer. The recommended dosage (two inhalations twice daily, morning and evening) should not be exceeded.

#6: Revised (new text in italics) -

"6. Patients should be cautioned regarding ["potential" deleted] common adverse cardiovascular effects, such as palpitations, ["or" deleted} chest pain, rapid heart rate, tremor, or nervousness ["related to the use of additional beta2-agonist" deleted]."

#9 & #10: New points-

"9. If you are pregnant or nursing, contact your physician about use of Serevent Inhalation Aerosol.

"10. Effective and safe use of Serevent Inhalation Aerosol includes an understanding of the way that is should be administered."

Drug Interactions: Addition of two paragraphs at end of subsection -

"Beta-adrenergic receptor blocking agents not only block the pulmonary effect of beta-agonists, such as Serevent Inhalation Aerosol, but may produce severe bronchospasm in asthmatic patients. Therefore, patients with asthma should not normally be treated with beta-blockers. However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-andrenergic blocking agents in patients with asthma. In this setting, cardioselective beta-blockers should be considered, although they should be administered with caution.

"The ECG changes and/or hypokalemia that may result from the administration of nonpotassium- sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of beta-agonists with nonpotassium-sparing diuretics."

Use in Labor and Delivery: Subsection revised (new text in italics) -

"There are no well-controlled human studies that have investigated effects of salmeterol on preterm labor or labor at term. Because of the potential for beta-agonist interference with uterine contractility, use of Serevent Inhalation Aerosol for relief of bronchospasm during labor should be restricted to those patients in whom the benefits clearly outweigh the risks."

OVERDOSAGE:
Section revised (new text in italics) -

"["Overdosage with salmeterol may be expected to result in exaggeration of the pharmacologic adverse effects associated with beta-adrenergic agonists, including tachycardia and/or arrhythmia, tremor, headache, and muscle cramps." deleted] The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of any of the symptoms listed under ADVERSE REACTIONS, e.g. seizures, angina, hyperension or hypotension, tachycardia with rates up to 200 beats per minute, arrhythmias, nervousness, headache, tremor, muscle cramps, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, and insomia. Overdosage with salmeterol can lead to clinically significant prolongation of the QTc interval, which can produce ventricular arrhythmias. Other signs of overdosage may include hypokalemia and hyperglycemia.

"[In these cases, therapy with Serevent Inhalation Aerosol and all beta-adrenergic stimulant drugs should be stopped, supportive therapy provided, and judicious use of a beta-adrenergic blocking agent should be considered, bearing in mind the possibility that such agents can produce bronchospasm. Cardiac monitoring is recommended in cases of overdosage." deleted]

"As with all sympathomimetic ["pressurized" deleted] aerosol medications, cardiac arrest and even death may be associated with abuse of Serevent Inhalation Aerosol. Treatment consists of discontinuation of Serevent Inhalation Aerosol together with appropriate symptomatic therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of Serevent Inhalation Aerosol.

"Rats and dogs survived the maximum practicable inhalation doses of salmeterol of ["2.9" deleted] 17.4 and ["0.7 mg/kg" deleted] 14.0 mg/m2, respectively. The maximum nonlethal oral doses in mice and rats were approximately ["150 mg/kg" deleted] 450 mg/m2 and ["1,000 mg/kg" deleted] > 6,000 mg/m2, respectively.

["Dialysis is not appropriate treatment for overdosage of Serevent Inhalation Aerosol." deleted]"

HOW SUPPLIED:
Third paragraph revised (new text in italics) -

"For use with Serevent Inhalation Aerosol actuator only. The actuator with Serevent Inhalation Aerosol should not be used with other aerosol medications, and actuators from other aerosol medications should not be used with a Serevent Inhalation Aerosol.

[November 20, 1997: Muro]

[Other changes not appearing in the 1998 PDR: Oct97]
CLINICAL PHARMACOLOGY:
First paragraph, last sentence revised (new text in italics) -

"The precise function of these [", however, is" deleted] receptors has not ["yet" deleted] been established. (See WARNINGS).

INDICATIONS AND USAGE:
Section revised (new text in italics) -

"Volmax Extended-Release Tablets are indicated for the relief of bronchospasm in ["patients" deleted] adults and children 6 years of age and older with reversible obstructive airway disease."

CONTRAINDICATIONS:
Section revised (new text in italics) -

"Volmax Extended-Release Tablets are contraindicated in patients with a history of hypersensitivity to albuterol or any of ["their" deleted] its components."

WARNINGS:
Cardiovascular Effects: First paragraph revised (new text in italics) -

"["Controlled clinical studies and other clinical experience have shown that albuterol" deleted] Volmax Extended-Release Tablets, like all other beta-adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients, as measured by pulse rate, blood pressure, and/or ["electrocardiographic changes" deleted] symptoms. although such effects are uncommon after administration of Volmax Extended-Release Tablets at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the T wave, prolongation of the QTc, and ST segment depression. The clinical significance of these findings is unknown. Therefore, Volmax Extended-Release Tablets, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension."

Deletion of last paragraph in subsection -

"As with other beta agonists, cardiac arrhythmias and sudden death have been reported in patients receiving Volmax. Whether these adverse events are directly related to Volmax administration is unclear."

Addition of new last paragraph in WARNINGS -

"Rarely, erythema multiforme and Stevens-Johnson syndrome have been associated with the administration of oral albuterol in children."

PRECAUTIONS:
Drug Interactions: First paragraph revised (new text in italics) -

"The concomitant use of Volmax Extended-Release Tablets and other oral sympathomimetic agents is not recommended since such combined use may lead to deleterious cardiovascular effects. this recommendation does not preclude the judicious use of an aerosol bronchodilator of the adrenergic stimulant type in patients receiving Volmax Extended-Release Taablets. Such concomitant use, however, should be individualized and not given on a routine basis. If regular coadministration is required, then alternative therapy should be considered."

Carcinogenesis, Mutagenesis, Impairment of Fertility: First paragraph revised (new text in italics) -
