CHROMITOPE SODIUM
[October 10, 1997: Bracco Diagnostics]
"Nuclear medicine procedures involving withdrawal and reinjection of blood have the potential for transmission of blood borne pathogens. Procedures should be implemented to avoid administration errors and viral contamination of personnel during blood product labeling. A system of checks similar to the ones used for administering blood transfusions should be routine."
COGNEX
[October 10, 1997: Parke-Davis]
"Cognex is contraindicated in patients previously treated with Cognex who developed treatment-associated jaundice ["confirmed by elevated total bilirubin greater than 3.0 mg/dL" deleted] ; a serum bilirubin > 3 mg/dL; and/or those exhibiting clinical signs or symptoms of hypersensitivity (eg, rash or fever) in association with ALT/SGPT elevations."
Cognex is an inhibitor of cholinesterase and may be expected to increase gastric acid secretion due to increased cholinergic activity. Therefore, patients are at increased risk for developing ulcers ["- eg," deleted]. Those with a history of ulcer disease or those receiving concurrent nonsteroidal anti-inflammatory drugs (NSAIDs) ["-" deleted] should be monitored closely for symptoms of active or occult gastrointestinal ["bleeding" deleted] disease.

"The limited usefulness of agents of this class (see ACTIONS) should be measured against possible risk factors inherent in their use such as those described below."
"Fastin capsules are indicated only as short-term monotherapy for the management of exogenous obesity. The safety and efficacy of combination therapy with phentermine and any other drug products for weight loss, including selective serotonin reuptake inhibitors (e.g., fluoxetine, sertraline, fluvoxamine, paroxetine), have not been established. Therefore, coadministration of these drug products for weight loss is not recommended.
"Primary Pulmonary Hypertension (PPH) - a rare, frequently fatal disease of the lungs - has been reported to occur in patients receiving a combination of phentermine with fenfluramine or dexfenfluramine. The possibility of an association between PPH and the use of phentermine alone cannot be ruled out; there have been rare cases of PPH in patients who reportedly have taken phentermine alone. The initial symptom of PPH is usually dyspnea. Other initial symptoms include: angina pectoris, syncope or lower extremity edema. Patients should be advised to report immediately any deterioration in exercise tolerance. Treatment should be discontinued in patients who develop new, unexplained symptoms of dyspnea, angina pectoris, syncope or lower extremity edema.
"Valvular Heart Disease: Serious regurgitant cardiac valvular disease, primarily affecting the mitral, aortic and/or tricuspid valves, has been reported in otherwise healthy persons who had taken a combination of phentermine with fenfluramine or dexfenfluramine for weight loss. The etiology of these valvulopathies has not been established and their course in individuals after the drugs are stopped is not known. There have been no reported cases to date of this valvular condition occurring with the use of phentermine alone."
Usage in Pregnancy: and Usage in Children: subsections deleted (see PRECAUTIONS below).
"Carcinogenesis, Mutagenesis, Impairment of Fertility: Studies have not been performed with Fastin (phentermine hydrochloride) to determine the potential for carcinogenesis, mutagenesis or impairment of fertility.
"Pregnancy - Teratogenic Effect: Pregnancy Category C. Animal reproduction studies have not been conducted with Fastin. It is also not known whether Fastin can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Fastin should be given to a pregnant woman only if clearly needed.
"Nursing Mothers: Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
"Pediatric Use: Safety and effectiveness in children have not been established."
"Primary pulmonary hypertension and/or regurgitant cardiac valvular disease (see WARNINGS) , palpitation tachycardia, elevation of blood pressure."

"In addition to adverse events reported from clinical trials, the following events have been identified during postapproval use of fluticasone propionate 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 either their seriousness, frequency of reporting, causal connection to fluticasone propionate, or a combination of these factors.
"Ear, Nose, and Throat: Throat soreness and irritation, hoarseness, laryngitis, aphonia.

"Norvir is indicated in combination with ["nucleoside analogues" deleted] other antiretroviral agents or as monotherapy for the treatment of HIV-infection ["when therapy is warranted" deleted]."
"Ritonavir co-administration is also expected to produce large increases in these highly metabolized sedatives and hypnotics: ["alprazolam," deleted] clorazepate, diazepam, estazolam, flurazepam, midazolam, triazolam, and zolpidem."
"New onset diabetes mellitus, exacerbation of pre-existing diabetes mellitus, and hyperglycemia have been reported during postmarketing surveillance in HIV-infected patients receiving protease inhibitor therapy. Some patients required either initiation or dose adjustments of insulin or oral hypoglycemic agents for treatment of these events. In some cases, diabetic ketoacidosis has occurred. In those patients who discontinued protease inhibitor therapy, hyperglycemia persisted in some cases. Because these events have been reported voluntarily during clinical practice, estimates of frequency cannot be made and a causal relationship between protease inhibitor therapy and these events has not been established."
"Ritonavir extensively inhibits the metabolism of saquinavir resulting in greatly increased saquinavir plasma concentrations. ["Co-administration of ritonavir 400 or 600 mg bid regimens produced greater than 20-fold increases in steady-state dose-normalized saquinavir concentrations in healthy subjects. The appropriate doses for this combination, with respect to activity and safety, have not been established." deleted] Following approximately 4 weeks of a combination regimen of saquinavir (400 or 600 mg bid) and ritonavir (400 or 600 mg bid) in HIV-infected patients, saquinavir AUC values were at least 17-fold greater than historical AUC values patients who received saquinavir 600 mg tid without ritonavir. When used in combination therapy for up to 24 weeks, doses greater than 400 mg bid of either ritonavir or saquinavir were associated with an increase in adverse events."

"The safety and efficacy of Omniscan at a single dose of 0.05 to 0.1 mmol/kg have been established in ["children 2 years of age and older (See INDICATIONS and USAGE and DOSAGE and ADMINISTRATION)" deleted] the pediatric population over 2 years of age. The safety and efficacy for doses greater than 0.1 mmol/kg and ["for" deleted] the clinical benefit of repeated procedures have not been studied in ["children" deleted] pediatric patients. ["The safety and efficacy for children under 2 years of age have not been established." deleted] The use of Omniscan in these age groups is supported by evidence from adequate and well controlled studies of Omniscan in adults, a pediatric study of the MR imaging of the central nervous system and additional safety data obtained in the literature.
"Pharmacokinetics of Omniscan have not been studied in the pediatric population. Literature reports that the glomerular filtration rate of neonates and infants is much less than that of adults. The pharmacokinetics volume of distribution is different as well. The effect of these differences on the elimination and dosing regimen in pediatric patients under 2 years of age has not been studied. Whether the dose administered or optimal imaging times should be adjusted has not been studied.
"However, in the 173 pediatric patients in the central nervous system Omniscan (see the Clinical Trials section) and the 144 pediatric patients in the literature, the adverse events were similar to those reported in adults."

"In 24-month carcinogenicity studies in rats, a dose-related significant increase in gastric carcinoid tumors and ECL cell hyperplasia was observed in both male and female animals (see PRECAUTIONS, Carcinogenesis, Mutagenesis, Impairment of Fertility). ["Hypergastrinemia secondary to prolonged and sustained hypochlorhydria has been postulated to be the mechanism by which ECL cell hyperplasia and gastric carcinoid tumors develop. Omeprazole may also affect other cells in the gastrointestinal tract (e.g. G cells), either directly or by inducing sustained hypochlorhydria, but this possibility has not been extensively studied." deleted] Carcinoid tumors have also been observed in rats subjected to fundectomy or long-term treatment with other proton pump inhibitors or high doses of H2-receptor antagonists.
"["Human gastric biopsy specimens from about 200 patients treated continuously with omeprazole for an average of over 12 months have not detected ECL cell effects of omeprazole similar to those seen in rats. Longer term data are needed to rule out the possibility of an increased risk for the development of gastric tumors in patients receiving long-term therapy with omeprazole" deleted]
"Human gastric biopsy specimens have been obtained from more than 3000 patients treated with omeprazole in long-term clinical trials. The incidence of ECL cell hyperplasia in these studies increased with time; however, no case of ECL cell carcinoids, dysplasia, or neoplasia has been found in these patients (See also CLINICAL PHARMACOLOGY, Pathogical Hypersecretory Conditions)."

"In approximately n=250 pediatric patients treated with Zoloft, the overall profile of adverse events was generally similar to that seen in adult studies, as shown in Tables 1 and 2. However, the following adverse events, not appearing in Tables 1 and 2, were reported at an incidence of at least 2% and occurred at a rate at least twice the placebo rate in a controlled trial (n=187): hyperkinesia, twitching, fever, malaise, purpura, weight decrease, concentration impaired, manic reaction, emotional lability, thinking abnormal, and epistaxis."
Other Events Observed During Postmarketing Experience with Zoloft: Increased coagulation times, bradycardia, AV block, atrial arrhythmias, hypothyroidism, leukopenia, thrombocytopenia, hyperglycemia, and priapism added to the list of adverse events temporally associated with Zoloft that have been received since market introduction, are not otherwise listed, and may have no causal relationship with the drug.
"In a placebo controlled, double-blind, randomized study of the comparative abuse liability of Zoloft, alprazolam, and d-amphetamine in humans, Zoloft did not produce the positive subjective effects indicative of abuse potential, such as euphoria or drug liking, that were observed with the other two drugs. Premarketing clinical experience with Zoloft did not reveal any tendency for a withdrawal syndrome or any drug-seeking behavior. In animal studies Zoloft does not demonstrate stimulant or barbiturate-like (depressant) abuse potential. As with any CNS active drug, however, physicians should carefully evaluate patients for history of drug abuse and follow such patients closely, observing them for signs of Zoloft misuse or abuse (e.g. development of tolerance, incrementation of dose, drug-seeking behavior)."
