Amikacin is also injected into the joints with the anti-arthritic medication Adequan in order to prevent infection.Side effects in animals include nephrotoxicity, ototoxicity, and allergic reactions at IM injection sites. Cats tend to be more sensitive to the vestibular damage caused by ototoxicity. Less frequent side effects include neuromuscular blockade, facial edema, and peripheral neuropathy.The half-life in most animals is one to two hours.Treating overdoses of amikacin requires kidney dialysis or peritoneal dialysis, which reduce serum concentrations of amikacin, and/or penicillins, some of which can form complexes with amikacin that deactivate it. Liposome inhalation suspension
Amikacin liposome inhalation suspension was the first drug approved under the US limited population pathway for antibacterial and antifungal drugs (LPAD pathway). It also was approved under the accelerated approval pathway. The U.S. Food and Drug Administration (FDA) granted the application for amikacin liposome inhalation suspension fast track, breakthrough therapy, priority review, and qualified infectious disease product (QIDP) designations. The FDA granted approval of Arikayce to Insmed, Inc.The safety and efficacy of amikacin liposome inhalation suspension, an inhaled treatment taken through a nebulizer, was demonstrated in a randomized, controlled clinical trial where patients were assigned to one of two treatment groups. One group of patients received amikacin liposome inhalation suspension plus a background multi-drug antibacterial regimen, while the other treatment group received a background multi-drug antibacterial regimen alone.
It does so in a time-dependent rather than dose-dependent manner, meaning that risk can be minimized by reducing the duration of use.Amikacin causes nephrotoxicity (damage to the kidneys), by acting on the proximal renal tubules. It easily ionizes to a cation and binds to the anionic sites of the epithelial cells of the proximal tubule as part of receptor-mediated pinocytosis. The concentration of amikacin in the renal cortex becomes ten times that of amikacin in the plasma; it then most likely interferes with the metabolism of phospholipids in the lysosomes, which causes lytic enzymes to leak into the cytoplasm. Nephrotoxicity results in increased serum creatinine, blood urea nitrogen, red blood cells, and white blood cells, as well as albuminuria (increased output of albumin in the urine), glycosuria (excretion of glucose into the urine), decreased urine specific gravity, and oliguria (decrease in overall urine output). It can also cause urinary casts to appear. The changes in renal tubular function also change the electrolyte levels and acid-base balance in the body, which can lead to hypokalemia and acidosis or alkalosis. Nephrotoxicity is more common in those with pre-existing hypokalemia, hypocalcemia, hypomagnesemia, acidosis, low glomerular filtration rate, diabetes mellitus, dehydration, fever, and sepsis, as well as those taking antiprostaglandins.
