Patients should be titrated in dose increments of ≤ 2.4 μg/day, up to a maximum dose of 21.6 μg/day. The minimal interval between dose increases is 24 hours; the recommended interval, for safety reasons, is 48 hours or more. If necessary the dose can be decreased by any amount (including stopping the infusion) for the management of adverse reactions. Approximately 75% of patients who respond satisfactorily to treatment require a dose of ≤ 9.6 μg/day. 15 Section 4.2: Posology and method of administration Other posology requirements Section index Example 10-maximum dose-single Maximum recommended dose (single) Active substance X 6,000 units. Powder and solvent for solution for injection Active substance X should be administered on the basis of body weight, with a maximum dose of 10,000 units (50 mg active substance X). 16 Section 4.2: Posology and method of administration Other posology requirements Section index Example 11-maximum dose-daily Maximum recommended dose (daily) Active substance X 20 mg powder for solution for injection The recommended dose is 40 mg administered intravenously (IV) or intramuscularly (IM), followed every 6 to 12 hours by 20 mg or 40 mg as required, not to exceed 80 mg/day. 17 Section 4.2: Posology and method of administration Other posology requirements Section index Example 12-maximum dose-total Maximum recommended dose (total) Active substance X Squamous cell carcinoma Intramuscular or intravenous injection of 10-15 x 103 IU/m2 once or twice a week. Treatment can be continued in the weeks following this or, which is more common, with intervals of 3-4 weeks, up to a total cumulative dose of 400 x 103 IU. 18 Section 4.2: Posology and method of administration Other posology requirements Section index Example 13-dose titration Dose titration Active substance X 100 micrograms buccal tablets Dose titration Active substance X should be individually titrated to an “effective” dose that provides adequate analgesia and minimises undesirable effects. In clinical studies, the effective dose of active substance X for breakthrough pain was not predictable from the daily maintenance dose of opioid. Patients should be carefully monitored until an effective dose is reached. Titration in patients not switching from other fentanyl containing products The initial dose of active substance X should be 100 micrograms, titrating upwards as necessary through the range of available tablets strengths (100, 200, 400, 600, 800 micrograms). Titration in patients switching from other fentanyl containing products Due to different absorption profiles, switching must not be done at a 1:1 ratio. If switching from another oral fentanyl citrate product, independent dose titration with active substance X is required as bioavailability between products differs significantly. However, in these patients, a starting dose higher than 100 micrograms may be considered.

    USING RHEOLOGY MEASUREMENT AS A POTENTIALLY PREDICTIVE TOOL FOR SOLDER PASTE TRANSFER EFFICIENCY AND PRINT VOLUME CONSISTENCY Mitch Holtzer, Karen Tellefsen and Westin Bent Alpha Assembly Solutions South Plainfield, NJ, USA [email protected] ABSTRACT Commercially available solder pastes use an upper and Industry standards such as J-STD-005 and JIS Z 3284-1994 lower limit for viscosity. Generally, this viscosity is call for the use of viscosity measurement(s) as a quality measured at one shear rate, typically the shear associated assurance test method for solder paste. Almost all solder with a spiral viscometer rotating at 10 revolutions per paste produced and sold use a viscosity range at a single minute (RPM).

  • Mometasone Powder Rationale for Inclusion In
    MOMETASONE POWDER RATIONALE FOR INCLUSION IN PA PROGRAM Background Mometasone is a corticosteroid demonstrating potent anti-inflammatory activity able to decrease inflammation through a mechanism of action that is not known. However, corticosteroids are thought to act by the induction of phospholipase A2, which leads to the inhibition of a common precursor for potent inflammatory mediators. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin increase percutaneous absorption (1). Mometasone is commercially available in the following dosage forms: topical cream, topical lotion, topical ointment, nasal spray and as a powder for inhalation. Regulatory Status FDA approved topical indication: Mometasone is a corticosteroid indicated for the relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses in patients 2 years of age and older (1). The safety and efficacy of mometasone have not been established in pediatric patients below 2 years of age (1). Summary Topical steroids have anti-inflammatory, antipruritic, and vasoconstrictive properties. Mometasone is FDA-approved for inflammatory and pruritic manifestations of corticosteroid- responsive dermatoses in patients 2 years of age and older. The safety and efficacy of mometasone have not been established in pediatric patients below 2 years of age (1). Mometasone is commercially available in the following dosage forms: topical cream, topical lotion, topical ointment, nasal spray and as powder for inhalation. Mometasone powder may be considered medically necessary in a topical formulation for patients 2 years of age or older for the treatment of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses. Mometasone powder may be considered investigational in a topical formulation for patients Mometasone Powder FEP Clinical Rationale MOMETASONE POWDER under the age of 2 years, or in patients without a diagnosis of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.

  • SODIUM POLYSTYRENE SULFONATE, USP Cation-Exchange Resin
    Kayexalate® SODIUM POLYSTYRENE SULFONATE, USP Cation-Exchange Resin DESCRIPTION Kayexalate, brand of sodium polystyrene sulfonate is a benzene, diethenyl-polymer, with ethenylbenzene, sulfonated, sodium salt and has the following structural formula: The drug is a cream to light brown finely ground, powdered form of sodium polystyrene sulfonate, a cation-exchange resin prepared in the sodium phase with an in vitro exchange capacity of approximately 3.1 mEq (in vivo approximately 1 mEq) of potassium per gram. The sodium content is approximately 100 mg (4.1 mEq) per gram of the drug. It can be administered orally or in an enema. CLINICAL PHARMACOLOGY As the resin passes along the intestine or is retained in the colon after administration by enema, the sodium ions are partially released and are replaced by potassium ions. For the most part, this action occurs in the large intestine, which excretes potassium ions to a greater degree than does the small intestine. The efficiency of this process is limited and unpredictably variable. It commonly approximates the order of 33 percent but the range is so large that definitive indices of electrolyte balance must be clearly monitored. Metabolic data are unavailable. INDICATION AND USAGE Kayexalate is indicated for the treatment of hyperkalemia. CONTRAINDICATIONS Kayexalate is contraindicated in the following conditions: patients with hypokalemia, patients with a history of hypersensitivity to polystyrene sulfonate resins, obstructive bowel disease, neonates with reduced gut motility (postoperatively or drug induced) and oral administration in neonates (see PRECAUTIONS). WARNINGS Intestinal Necrosis: Cases of intestinal necrosis, which may be fatal, and other serious gastrointestinal adverse events (bleeding, ischemic colitis, perforation) have been reported in association with Kayexalate use.

Abstract Earlier methods adopted for the estimation of median lethal dose (LD50) used many animals (40 – 100). But for the up – and – down procedure, 5 – 15 animals can be used, the number I still consider high. So this paper seeks to adopt arithmetic, geometric and harmonic (AGH) mean for rough estimation of median lethal dose (LD50) using up – and – down procedure by using 2 – 6 animals that may likely give 1 – 3 reversals. The administrated doses should be summed up and the mean, standard deviation (STD) and standard error of mean (SEM) should be determined.

  • Test No. 408: Repeated Dose 90-Day Oral Toxicity Study in Rodents
    OECD/OCDE 408 Adopted: 25 June 2018 │ OECD GUIDELINE FOR THE TESTING OF CHEMICALS Repeated dose 90-day oral toxicity study in rodents INTRODUCTION 1. OECD Guidelines for the Testing of Chemicals are periodically reviewed in the light of scientific progress, changing regulatory needs, and animal welfare considerations. The original guideline 408 was adopted in 1981. In 1998 a revised version was adopted, to obtain additional information from the animals used in the study, based on the outcome of an OECD Consultation Meeting of Experts on Sub- chronic and Chronic Toxicity Testing held in Rome in 1995 (1). 2. This Test Guideline (TG) was updated in 2018 to add endocrine-sensitive endpoints intended to improve detection of potential endocrine activity of test chemicals and mirrors updates to TG 407 (Repeated Dose 28-Day Oral Toxicity Study in Rodents). INITIAL CONSIDERATIONS 3. In the assessment and evaluation of the toxic characteristics of a chemical, the determination of sub-chronic oral toxicity using repeated doses may be carried out after initial information on toxicity has been obtained from acute or repeated dose 28-day toxicity tests. The 90- day study provides information on the possible health hazards likely to arise from repeated exposure over a prolonged period of time covering post-weaning maturation and growth into adulthood of the test animals. The study will provide information on the major toxic effects, indicate target organs and the possibility of accumulation of test chemical, and can provide an estimate of a no-observed-adverse-effect level (NOAEL) of exposure which can be used in selecting dose levels for chronic studies and for establishing safety criteria for human exposure.
