If sepsis is being considered, empiric therapy may be initiated prior to susceptibility testing.Medical uses include:
lower respiratory tract infections
acute bacterial otitis media
skin and skin structure infections
urinary tract infections
uncomplicated gonorrhea
pelvic inflammatory disease
bacterial sepsis
intra-abdominal infections
meningitis
surgical prophylaxis
Lyme diseaseCeftriaxone is also a choice drug for treatment of bacterial meningitis caused by pneumococci, meningococci, Haemophilus influenzae, and "susceptible enteric Gram-negative rods, but not Listeria monocytogenes. "In combination with doxycycline or azithromycin, ceftriaxone used to be recommended by the United States Centers for Disease Control and Prevention (CDC) for the treatment of uncomplicated gonorrhea. Due to increased risk of developing azithromycin resistant strains and the high efficacy of higher doses of ceftriaxone the guidance has been updated to mono-antibiotic therapy with a higher dose of ceftriaxone. Spectrum of activity
Like other third-generation cephalosporins, ceftriaxone is active against Citrobacter spp., Serratia marcescens, and beta-lactamase-producing strains of Haemophilus and Neisseria. However, unlike ceftazidime and cefoperazone, ceftriaxone does not have useful activity against Pseudomonas aeruginosa. It is generally not active against Enterobacter species, and its use should be avoided in the treatment of Enterobacter infections, even if the isolate appears susceptible, because of the emergence of resistance. Some organisms, such as Citrobacter, Providencia, and Serratia, have the ability to become resistant through the development of cephalosporinases (enzymes that hydrolyze cephalosporins and render them inactive). Available forms
Ceftriaxone is available for administration via the intramuscular or the intravenous routes. Diluents containing calcium should not be used to reconstitute ceftriaxone, and it must not be administered in intravenous lines containing other calcium-containing solutions, as a ceftriaxone-calcium precipitate could form.
Pramlintide (trade name Symlin) is an injectable amylin analogue drug for diabetes (both type 1 and 2), developed by Amylin Pharmaceuticals (now a wholly owned subsidiary of AstraZeneca). Pramlintide is sold as an acetate salt. Pharmacology
Pramlintide is an analogue of amylin, a small peptide hormone that is released into the bloodstream by the β cells of the pancreas along with insulin after a meal. Like insulin, amylin is completely absent in individuals with Type I diabetes.In synergy with endogenous amylin, pramlintide aids in the regulation of blood glucose by slowing gastric emptying, promoting satiety via hypothalamic receptors (different receptors than for GLP-1), and inhibiting inappropriate secretion of glucagon, a catabolic hormone that opposes the effects of insulin and amylin. Pramlintide also has effects in raising the acute first-phase insulin response threshold following a meal. Both a reduction in glycated hemoglobin and weight loss have been shown in insulin-treated patients with type 2 diabetes taking pramlintide as an adjunctive therapy. Research Applications
In the research field, pramlintide has been experimented with and used as a potential treatment drug. Pramlintide has demonstrated its ability to decrease amyloid beta plaques in Alzheimers disease mouse models. Approval
Pramlintide has been approved by the FDA, for use by type 1 and type 2 diabetic patients who use insulin. Pramlintide allows patients to use less insulin, lowers average blood sugar levels, and substantially reduces what otherwise would be a large unhealthy rise in blood sugar that occurs in diabetics right after eating.
