Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Percorten (desoxycorticosterone pivalate) is a synthetic mineralocorticoid that binds to and activates the mineralocorticoid receptor (MR) in the renal distal tubule, leading to increased sodium reabsorption, increased potassium and hydrogen ion excretion, and water retention, thereby expanding extracellular fluid volume and increasing blood pressure.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of m RNA and inhibiting protein synthesis. Also disrupts bacterial cell membrane integrity.
Adjunctive therapy in adrenocortical insufficiency (Addison's disease) for mineralocorticoid replacement,Off-label: Treatment of orthostatic hypotension due to autonomic dysfunction
FDA-approved: Treatment of serious gram-negative bacterial infections (e.g., Pseudomonas aeruginosa, Escherichia coli, Klebsiella, Enterobacter, Serratia, Proteus) when other antibiotics are ineffective or contraindicated.,Off-label: Used in combination for enterococcal endocarditis, mycobacterial infections (e.g., tuberculosis), and severe neonatal sepsis.
1-5 mg intramuscularly or subcutaneously daily with dose adjusted based on clinical response and electrolyte monitoring.
15 mg/kg/day IV or IM divided every 8-12 hours; typical adult dose 500 mg IV/IM every 12 hours or 7.5 mg/kg every 12 hours.
Terminal elimination half-life is approximately 30-40 minutes. Clinically, the short half-life necessitates frequent dosing (e.g., every 6-12 hours) to maintain therapeutic effect in mineralocorticoid replacement.
Terminal: 2-3 hours (normal renal function); prolonged to 30-50 hours in anuria; neonates 4-8 hours.
Primarily hepatic via reduction and conjugation; excreted in urine as metabolites. Desoxycorticosterone pivalate is a prodrug that is hydrolyzed to desoxycorticosterone, which is then metabolized.
Amikacin is not significantly metabolized; it is excreted unchanged primarily by glomerular filtration. Minimal hepatic metabolism.
Renal (biliary/fecal negligible). Approximately 50-70% of a dose is excreted as metabolites in urine; <5% unchanged.
Renal: >90% unchanged via glomerular filtration. Biliary/fecal: <1%.
Approximately 90-94% bound to albumin and corticosteroid-binding globulin (CBG).
0-11% (low binding to albumin).
Vd approximately 0.5-0.8 L/kg. Clinical meaning: Distributes primarily into extracellular fluid; low Vd indicates limited tissue penetration.
0.25-0.4 L/kg; approximates extracellular fluid volume; increased in edema, decreased in dehydration.
Oral: Approximately 50-70% (high first-pass metabolism). IM/SC: 100% (assumed).
IM: nearly 100% (rapid and complete).
No specific GFR-based dose adjustments established; use with caution in renal impairment due to potential for fluid retention and hypertension.
Cr Cl 20-50 m L/min: 7.5 mg/kg every 24 hours; Cr Cl 10-20 m L/min: 7.5 mg/kg every 48 hours; Cr Cl <10 m L/min: 7.5 mg/kg every 72-96 hours; hemodialysis: 7.5 mg/kg post-dialysis with monitoring.
No specific Child-Pugh based dose adjustments; caution in severe hepatic impairment due to reduced metabolism and increased risk of adverse effects.
No dose adjustment required for hepatic impairment; monitor drug levels if severe dysfunction.
0.1-0.3 mg/kg intramuscularly or subcutaneously daily, divided every 12-24 hours, with titration based on clinical response.
Neonates <7 days: 15-20 mg/kg IV every 24-48 hours; neonates 7-28 days: 15 mg/kg every 24 hours; infants/children: 15-22.5 mg/kg/day divided every 8-12 hours; maximum 1.5 g/day.
Initiate at lower end of adult dose (1 mg daily) with careful monitoring for fluid overload and electrolyte disturbances due to age-related renal and cardiovascular changes.
Reduce initial dose based on renal function; usual dose 7.5 mg/kg every 24-48 hours with close monitoring of serum creatinine and drug levels due to age-related decreased GFR.
None
WARNING: Amikacin can cause neurotoxicity, ototoxicity, and nephrotoxicity. The risk of nephrotoxicity is greater in patients with impaired renal function and those receiving high doses or prolonged therapy. Ototoxicity may be irreversible and can occur even after drug discontinuation. Monitor renal function and drug levels closely.
May cause severe hypertension, edema, congestive heart failure, hypokalemia, or metabolic alkalosis. Monitor blood pressure, serum electrolytes, and body weight. Use with caution in patients with cardiac disease, renal impairment, or hepatic disease. Avoid excessive sodium intake.
Nephrotoxicity: Risk increased with advanced age, pre-existing renal impairment, concomitant use of other nephrotoxic drugs (e.g., amphotericin B, cyclosporine, NSAIDs).,Ototoxicity: Can cause irreversible bilateral hearing loss, tinnitus, and vestibular damage. Monitor audiometry in patients with risk factors.,Neuromuscular blockade: May exacerbate weakness in patients with neuromuscular disorders (e.g., myasthenia gravis, Parkinsonism). Use with caution during anesthesia or with neuromuscular blocking agents.,Hypersensitivity reactions: Including rash, drug fever, and anaphylaxis.,Superinfection: Prolonged use may lead to overgrowth of nonsusceptible organisms.,Pregnancy: Risk of fetal harm (ototoxicity) if administered during pregnancy.
Hypersensitivity to desoxycorticosterone or any component,Severe hypertension,Hyperkalemia,Edema or fluid overload states,Congestive heart failure,Severe renal impairment
Hypersensitivity to amikacin, other aminoglycosides, or any component of the formulation.,Preexisting severe renal impairment (unless life-threatening infection and no alternative).,Concurrent use of other nephrotoxic or ototoxic drugs (relative contraindication).,Myasthenia gravis (caution; neuromuscular blocking effect).
Avoid high-potassium foods (e.g., bananas, oranges, salt substitutes) as Percorten increases potassium retention. Limit sodium intake to manage fluid balance.
No significant food interactions. Avoid alcohol as it may increase side effects like dizziness.
Percorten (desoxycorticosterone pivalate) is a mineralocorticoid. Data in pregnant women are limited. In animal studies, corticosteroids have been shown to be teratogenic. Use during pregnancy only if clearly needed. First trimester: Possible increased risk of cleft palate and intrauterine growth restriction. Second and third trimesters: Potential for adrenal suppression in the fetus/newborn.
Aminoglycosides including amikacin have been associated with fetal ototoxicity and nephrotoxicity when administered during pregnancy. There is a potential for eighth cranial nerve damage and renal impairment in the fetus, particularly during the second and third trimesters. Animal studies have shown evidence of harm, but controlled human studies are lacking. Use only if clearly needed and if safer alternatives are unavailable.
Corticosteroids are excreted in breast milk in small amounts. Desoxycorticosterone pivalate specific data are lacking. M/P ratio not determined. At high maternal doses, monitor infant for signs of adrenal suppression. Use with caution.
Amikacin is excreted into human milk in low concentrations. The milk-to-plasma ratio is approximately 0.1–0.2. Due to low oral bioavailability from the gastrointestinal tract, systemic effects in the breastfed infant are unlikely. However, caution is advised due to the potential for altered infant gut flora and direct mucosal irritation. Use only if benefits outweigh risks.
Pregnancy may increase clearance of corticosteroids, potentially requiring dose adjustments. However, specific pharmacokinetic data for Percorten are lacking. Use lowest effective dose and monitor clinical response and serum levels if available.
Pregnancy does not typically require dosing adjustments for amikacin. However, due to increased glomerular filtration rate during pregnancy, levels may be lower; monitor drug concentrations and adjust doses to achieve therapeutic range. Standard dosing based on ideal body weight and renal function should be followed.
Percorten (desoxycorticosterone pivalate) is a mineralocorticoid used for adrenal insufficiency. Monitor for hypertension, hypokalemia, and edema. Titrate dose based on blood pressure and serum potassium. Use with caution in heart failure or renal impairment.
Monitor peak (15-30 mcg/m L) and trough (<5 mcg/m L) levels to avoid nephrotoxicity and ototoxicity. Adjust dose in renal impairment using Cr Cl. Synergy with beta-lactams for Gram-negative infections. Avoid concurrent loop diuretics.
Take exactly as prescribed; do not miss doses.,Report rapid weight gain, swelling, or shortness of breath.,Avoid excessive salt intake; follow a low-sodium diet if advised.,Do not stop abruptly; taper under medical supervision.
Take exactly as prescribed; do not skip doses or stop early.,Report any hearing loss, tinnitus, dizziness, or vertigo immediately.,Drink plenty of fluids to maintain hydration, unless contraindicated.,Avoid taking other medications without consulting your doctor, especially water pills or other antibiotics.
No interactions on record
"Amikacin, an aminoglycoside antibiotic, may competitively inhibit the renal tubular secretion and potentially reduce the clearance of masoprocol, a dicarboxylic acid derivative used as a chemotherapeutic agent. This interaction could lead to increased systemic exposure to masoprocol, elevating the risk of dose-dependent toxicities such as severe enteritis, myelosuppression, and hepatotoxicity. Given the narrow therapeutic index of masoprocol, even modest elevations in serum levels may result in clinically significant adverse outcomes."
"Amikacin, an aminoglycoside antibiotic, may competitively inhibit the tubular secretion of mycophenolic acid (MPA) in the renal proximal tubules, leading to reduced renal clearance of MPA. This interaction can result in elevated serum levels of MPA, increasing the risk of dose-related toxicities such as bone marrow suppression (leukopenia, thrombocytopenia), gastrointestinal disturbances, and increased susceptibility to infections. Patients receiving this combination should be closely monitored for signs of MPA toxicity, especially those with pre-existing renal impairment."
"Coadministration of Metocurine, a nondepolarizing neuromuscular blocking agent, with Amikacin, an aminoglycoside antibiotic, may result in enhanced and prolonged neuromuscular blockade. Aminoglycosides can impair acetylcholine release from presynaptic nerve terminals and reduce postsynaptic sensitivity, synergistically augmenting the effects of nondepolarizing agents. This interaction can lead to excessive muscle relaxation, including respiratory muscle paralysis, increasing the risk of apnea and postoperative respiratory depression."
