"Impairment of male fertility was observed in reproductive studies performed in rats ["and rabbits" deleted] at a dose of 800 mg/kg/day (4800 mg/m2)."

ADVERSE REACTIONS:
Postmarketing Reports (new subsection):

"The following events have been identified during post-approval use of products which contain (or are metabolized to) mesalamine in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of seriousness, frequency of reporting, or potential causal connection to mesalamine:

"Gastrointestinal: Reports of hepatotoxicity, including elevated liver function tests (SGOT / AST, SGPT / ALT, GGT, LDH, alkaline phosphatase, bilirubin), jaundice, cholestatic jaundice, cirrhosis, and possible hepatocellular damage including liver necrosis and liver failure. Some of these cases were fatal. One case of Kawasaki-like syndrome, which included hepatic function changes, was also reported."

BRETYLIUM TOSYLATE Injection
[August 26, 1999: Abbott]

WARNINGS:
Hypotension: Text added as new third paragraph -

"Patients over 65 years may be at increased risk of developing orthostatic hypotension, especially when the recommended rate of intravenous infusion is exceeded. See DOSAGE AND ADMINISTRATION."

PRECAUTIONS:
Geriatric Use (new subsection):

"Clinical studies of bretylium did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or drug therapy.

"Intravenous infusion, especially if administered at a rate beyond that recommended in the DOSAGE AND ADMNISTRATION section, may produce an increased risk of orthostatic hypotension in the elderly. See WARNINGS.

"This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function, See CLINICAL PHARMACOLOGY."

DOSAGE AND ADMINISTRATION:
A. For immediately Life-threatening Ventricular Arrhythmias such as Ventricular Fibrillation or Hemodynamically Unstable Ventricular Tachycardia:

Second paragraph, last sentence revised (new text in italics) -

"More rapid infusion may cause nausea and vomiting, and in patients older than 65 years, may increase the risk of developing orthostatic hypotension."

B. Other Ventricular Arrhythmias: 1. Intravenous Use: Second paragraph, second sentence revised (new text in italics) -

"More rapid infusion may cause nausea and vomiting, and in patients older than 65 years, may increase the risk of developing orthostatic hypotension."

[Other information regarding these changes: Letter]

BOXED WARNING (new section):

"Hepatic Injury
There have been post-marketing reports of hospitalization and rarely death due to liver failure in patients taking flutamide. Evidence of hepatic injury included elevated serum transaminase levels, jaundice, hepatic encephalopathy and death related to acute hepatic failure. The hepatic injury was reversible after discontinuation of therapy in some patients. Approximately half of the reported cases ocurred within the initial 3 months of treatment with flutamide.

"Serum transaminase levels should be measured prior to starting treatment with flutamide. Flutamide is not recommended in patients whose ALT values exceed twice the upper limit of normal. Serum transaminase levels should then be measured monthly for the first 4 months of therapy, and periodically thereafter. Liver function tests also should be obtained at the first signs and symptoms suggestive of liver dysfunction, e.g., nausea, vomiting, abdominal pain, fatigue, anorexia, "flu-like" symptoms, hyperbilirubinuria, jaundice or right upper quadrant tenderness. If at any time, a patient has jaundice, or their ALT rises above 2 times the upper limit of normal, flutamide should be immediately discontinued with close follow-up of liver function tests until resolution."

CLINICAL PHARMACOLOGY:
Special Populations: Hepatic Impairment: subsection revised (new text in italics) -

"No information on the pharmacokinetics of flutamide in hepatic impairment is available (see BOXED WARNINGS, Hepatic Injury)."

Women, Pediatrics (new subsection):

"Flutamide has not been studied in women or pediatric subjects."

Stage B2-C Prostatic Carcinoma: First paragraph revised (new text in italics) -

"The effects of hormonal treatment combined with radiation was studied in 466 patients (231 Eulexin + ["LHRH-A" deleted] goserelin acetate implant+ radiation, 235 radiation alone) with ..."

INDICATIONS AND USAGE:
Stage B2-C Prostatic Carcinoma: Subsection revised (new text in italics) -

"Treatment with Eulexin and the ["LHRH agonist" deleted] goserelin acetate implant should start eight weeks ..."

CONTRAINDICATIONS:
Second paragraph added -

"Eulexin capsules are contraindicated in patients with severe hepatic impairment (baseline hepatic enzymes should be evaluated prior to treatment)."

WARNINGS:
Existing text deleted and replaced with -

"Hepatic injury: SEE BOXED WARNING

"Use in Women: This product has no indication for women, and should not be used in this population, particularly for non-serious or non-life threatening conditions.

"Fetal toxicity: Flutamide may cause fetal harm when administered to a pregnant woman (see Pregnancy).

"Aniline toxicity: One metabolite of flutamide is 4-nitro-3-fluoro-methylaniline. Several toxicities consistent with aniline exposure, including methemoglobinemia, hemolytic anemia and cholestatic jaundice have been observed in both animals and humans after flutamide administration. In patients susceptible to aniline toxicity (e.g., persons with glucose-6-phosphate dehydrogenase deficiency, hemoglobin M disease and smokers), monitoring of methemoglobin levels should be considered."

PRECAUTIONS:
General (new subsection):

"In clinical trials, gynecomastia occurred in 9% of patients receiving flutamide together with medical castration."

Laboratory Tests: Second paragraph deleted -

"Since transaminase abnormalities and rarely jaundice have been reported with the use of Eulexin, periodic liver function tests should be considered, e.g., when the patient has jaundice or laboratory evidence of liver injury in the absence of liver metastases. Eulexin therapy should be discontinued. Abnormalities are usually reversible upon discontinuation. See WARNINGS, Hepatic Injury above."

Animal Toxicology (new subsection):

"Serious cardiac lesions were observed in 2/10 beagle dogs receiving 25 mg/kg/day for 78 weeks and 3/16 receiving 40 mg/kg/day for 2-4 years. These lesions, indicative of chronic injury and repair processes, included chronic myxomatous degeneration, intra-arterial fibrosis, myocardial acidophilic degeneration, vasculitis and perivasculitis. The doses at which these lesions occurred were associated with 2-hydroxyflutamide levels that were 1 to 12-fold greater than those observed in humans at therapeutic levels."

Pregnancy: Pregnancy Category D:

Existing text -

"See WARNINGS section."

deleted and replaced with -

"There was decreased 24-hour survival in the offspring of pregnant rats treated with flutamide at doses of 30, 100, or 200 mg/kg/day (approximately 3, 9, and 19 times the human dose). A slight increase in minor variations in the development of the sternabrae and vertabrae was seen in fetuses of cats treated with higher doses. Feminization of the male cats also occurred at the two higher dose levels. There was a decreased survival rate in the offspring of rabbits receiving the highest dose (15 mg/kg/day, equal 1.4 times the human dose)."

ADVERSE REACTIONS:
Stage B2-C Prostatic Carcinoma: First paragraph, first and second sentences revised (new text in italics) -

"Treatment with Eulexin and the ["LHRH agonist" deleted] goserelin acetate implant did not add substantially to the toxicity of radiation treatment alone. The following adverse experiences were reported during a multi-center clinical trial comparing Eulexin + ["LHRH-A" deleted] goserelin acetate implant + radiation versus radiation alone."

Stage D2 Metastatic Carcinoma: Fifth paragraph, second sentence deleted -

"No causal relatedness of these reactions to drug treatment has been made, and some of the adverse experiences reported are those that commonly occur in elderly patients."

Paragraph beginning - "In addition, the following spontaneous adverse experiences have been reported..."

First sentence: - "sulfhemoglobinemia" added.

Last sentence revised (new text in italics) - "The hepatic conditions were ["usually" deleted] often reversible after discontinuing therapy... "

Last paragraph -

Text deleted and replaced with -

"Malignant breast neoplasms have occurred rarely in male patients being treated with Eulexin."

Text deleted -

"Two reports of malignant breast neoplasms occurring in male patients being dosed with Eulexin Capsules have been reported. One involved a pre-existing nodule which was first detected 3-4 months before initiation of Eulexin monotherapy. After excision, this nodule was diagnosed as a poorly differentiated ductal carcinoma. The other report involved gynecomastia and a breast nodule noted 2 and 6 months, respectively, after initiation of Eulexin monotherapy. The nodule was excised and diagnosed as a moderately differentiated invasive ductal tumor."

OVERDOSAGE:
Third paragraph, first sentence -

"Since flutamide is highly protein bound, dialysis may not be of any use as treatment for overdose."

deleted and replaced with -

"Flutamide is highly protein bound and is not cleared by hemodialysis."

FURADANTIN (nitrofurantoin) Oral Suspension
[August 25, 1999: Dura]

[Other labeling changes not appearing in 1999 PDR: Mar97, Feb98, Feb99]

[Click Here to see new labeling.]

CLINICAL PHARMACOLOGY:
Susceptibility Tests: Existing text deleted and replaced with -

"Dilution Techniques:
Quantitative methods are used to determine antimicrobial minimal inhibitory concentrations (MIC's). These MIC's provide estimates of the susceptibility of bacteria to antimicrobial compounds. The MIC's should be determined using a standardized procedure. Standardized procedures are based on a dilution method (broth or agar) or equivalent with standardized inoculum concentrations and standardized concentrations of nitrofurantoin powder. The MIC values should be interpreted according to the following criteria:

Microorganism

MIC (mcg/mL)

E. coli ATCC 25922

4-16

S. aureus ATCC 29213

8-32

E. faecalis ATCC 29212

4-16

"A report of "Susceptible" indicates that the pathogen is likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable. A report of "Intermediate" indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone which prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of "Resistant" indicates that the pathogen is not likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable; other therapy should be selected.

"Standardized susceptibility test procedures require the use of laboratory control microorganisms to control the technical aspects of the laboratory procedures. Standard nitrofurantoin powder should provide the following MIC values:

MIC (mcg/mL)

Interpretation

# 32

Susceptible (S)

64

Intermediate (I)

$ 128

Resistant (R)

"Diffusion Techniques:
Quantitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. One such standardized procedure requires the use of standardized inoculum concentrations. This procedure uses paper disks impregnated with 300 mcg nitrofurantoin to test the susceptibility of microorganisms to nitrofurantoin.

"Reports from the laboratory providing results of the standard single-disk susceptibility test with a 300 mcg trimethoprim disk should be interpreted according to the following criteria:

Zone diameter (mm)

Interpretation

$ 17

Susceptible (S)

15-16

Intermediate (I)

# 14

Resistant (R)

"Interpretation should be as stated above for results using dilution techniques. Interpretation involves correlation of the diameter obtained in the disk test with the MIC for nitrofurantoin.

"As with standardized dilution techniques, diffusion methods require the use of the laboratory control microorganisms that are used to control the technical aspects of the laboratory procedures. For the diffusion technique, the 300 mcg nitrofurantoin disk should provide the following zone diameters in these laboratory test quality control strains:

Microorganism

MIC (mcg/mL)

E. coli ATCC 25922

20-25

S. aureus ATCC 25923

PRECAUTIONS:
Pediatric Use (new subsection):

"The safety and effectiveness of lidocaine has not been established in pediatric patients (neonates to adolescents)."

Geriatric Use (new subsection):

"Clinical studies of Lidocaine HCl did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Lidocaine is substantially excreted by the kidney and clearance of Lidocaine is decreased in the elderly (see CLINICAL PHARMACOLOGY). In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased renal or cardiac function, and of concomitant disease or other drug therapy."

[August 6, 1999: Glaxo Wellcome]

CLINICAL PHARMACOLOGY:
Susceptibility Tests [subsection name changed from "Susceptibility Testing"]: Existing text deleted and replaced with -

"Dilution Techniques
Quantitative methods are used to determine antimicrobial minimal inhibitory concentrations (MICs). These MICs provide estimates of the susceptibility of bacteria to antimicrobial compounds. The MICs should be determined using a standardized procedure. Standardized procedures are based on a dilution method (broth or agar) or equivalent with standardized inoculum concentrations and standardized concentrations of trimethoprim powder. The MIC values should be interpreted according to the following criteria:

MIC (mcg/mL)

Interpretation

# 8

Susceptible (S)

$ 16

Resistant (R)

"A report of "Susceptible" indicates that the pathogen is likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable. A report of "Intermediate" indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone which prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of "Resistant" indicates that the pathogen is not likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable; other therapy should be selected.

"Standardized susceptibility test procedures require the use of laboratory control microorganisms to control the technical aspects of the laboratory procedures. Standard trimethoprim powder should provide the following MIC values:

Microorganism

MIC (mcg/mL)

S. aureus ATCC 29213

1-4

E. faecalis ATCC 29212

# 1

E. coli ATCC 25922

0.5-2

P. aeruginosa ATCC 27853

>64

"Diffusion Techniques
Quantitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. One such standardized procedure requires the use of standardized inoculum concentrations. This procedure uses paper disks impregnated with 5 mcg trimethoprim to test the susceptibility of microorganisms to trimethoprim.

"Reports from the laboratory providing results of the standard single-disk susceptibility test with a 5 mcg trimethoprim disk should be interpreted according to the following criteria:

Zone diameter (mm)

Interpretation

$ 16

Susceptible (S)

11-15

Intermediate (I)

# 10

Resistant (R)

"Interpretation should be as stated above for results using dilution techniques. Interpretation involves correlation of the diameter obtained in the disk test with the MIC for trimethoprim.

"As with standardized dilution techniques, diffusion methods require the use of the laboratory control microorganisms that are used to control the technical aspects of the laboratory procedures. For the diffusion technique, the 5 mcg trimethoprim disk should provide the following zone diameters in these laboratory test quality control strains:

Microorganism

Zone Diameter (mm)

E. coli ATCC 25922

21-28

S. aureus ATCC 25923

19-26

PROSCAR (finasteride) Tablets
[August 2, 1999: Merck]

PRECAUTIONS:
Effects on PSA and Prostate Cancer Detection: New fourth paragraph added -

"Percent free PSA (free to total PSA ratio) is not significantly decreased by Proscar. The ratio of free to total PSA remains constant even under the influence of Proscar. If clinicians elect to use percent free PSA as an aid in the detection of prostate cancer in men undergoing finasteride therapy, no adjustment to its value appears necessary."

SECTRAL (acebutolol HCl) Capsules
[August 22, 1999: Wyeth-Ayerst]

PRECAUTIONS:
Geriatric Use (new subsection):

"Clinical studies of Sectral and other reported clinical experience is inadequate to determine whether there are differences in safety or effectiveness between patients above or below age 65.

"Elderly subjects evidence greater bioavailability of acebutolol (See CLINICAL PHARMACOLOGY - Pharmacokinetics and Metabolism), presumably because of age-related reduction in first-pass metabolism and renal function. Therefore, it may be appropriate to start elderly patients at the low end of the dosing range (see DOSAGE AND ADMINISTRATION - Use in Older Patients)."

ZAROXOLYN (metolazone) Tablets
[August 13, 1999: Medeva]

PRECAUTIONS:
Pediatric Use:

"Safety and effectiveness in pediatric patients have not been established and such use is not recommended."

deleted and replaced with -

"Safety and effectiveness in pediatric patients have not been established in controlled clinical trials. There is limited experience with the use of Zaroxolyn in pediatric patients with congestive heart failure, hypertension, bronchopulmonary dysplasia, nephrotic syndrome, and nephrogenic diabetes insipidus. Doses used generally ranged from 0.05 to 0.1 mg/kg administered once daily and usually resulted in a 1 to 2.8 kg weight loss and 150 to 300 cc increase in urine output. Not all patients responded and some gained some weight. Those patients who did respond did so in the first few days of treatment. Prolonged use (beyond a few days) was generally associated with no further beneficial effect or a return to baseline status and is not recommended.

"There is limited experience with the combination of Zaroxolyn and furosemide in pediatric patients with furosemide-resistant edema. Some benefitted while others did not or had an exaggerated response with hypovolemia, tachycardia, and orthostatic hypotension requiring fluid replacement. Severe hypokalemia was reported and there was a tendency for diuresis to persist for up to 24 hours after Zaroxolyn was discontinued. Hyperbilirubinemia has been reported in 1 neonate. Close clinical and laboratory monitoring of all children treated with diuretics is indicated. See CONTRAINDICATIONS, WARNINGS, PRECAUTIONS."

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

"Store at ["room temperature" deleted] 25oC (77Fo); excursions permitted to 15-30oC (59-86Fo) [See USP Controlled Room Temperature]. ["Dispense in a tight-light resistant container." deleted]. Protect from light. Keep out of the reach of children."
