Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of m RNA and inhibition of protein synthesis.
Finerenone is a nonsteroidal, selective antagonist of the mineralocorticoid receptor (MR). It binds to the MR and inhibits the recruitment of coactivators, thereby reducing the expression of pro-inflammatory and pro-fibrotic mediators in the kidney and heart.

To reduce the risk of sustained e GFR decline, end-stage kidney disease, cardiovascular death, non-fatal myocardial infarction, and hospitalization for heart failure in adult patients with chronic kidney disease (CKD) associated with type 2 diabetes.
15 mg/kg/day IV divided every 8-12 hours (usual adult dose: 15 mg/kg/day).
10 mg orally once daily initially, then titrate to 20 mg once daily after 4 weeks if tolerated.
Terminal elimination half-life: 2–3 hours in patients with normal renal function; may be prolonged to 30–60 hours in anuria.
The terminal elimination half-life is approximately 2–4 hours in healthy subjects. In patients with renal impairment, the half-life may be prolonged up to 6–8 hours, allowing for once-daily dosing in chronic kidney disease.
Primarily excreted unchanged by glomerular filtration. Minimal hepatic metabolism.
Primarily metabolized by CYP3A4 (≈90%) and to a lesser extent by CYP2C8 (≈10%). No active metabolites.
Renal excretion of unchanged drug via glomerular filtration; >90% eliminated unchanged in urine within 24 hours. Biliary/fecal excretion <1%.
Approximately 80% of the dose is eliminated via feces (primarily as unchanged drug) and ~20% via urine (mostly as metabolites). Renal excretion of unchanged drug is minimal (less than 1%).
Low protein binding; 0–11% bound, primarily to albumin.
Approximately 92% bound to plasma proteins, primarily albumin and alpha-1 acid glycoprotein.
Vd: 0.25–0.4 L/kg; approximates extracellular fluid volume. Increased in edema, ascites; decreased in dehydration.
The apparent volume of distribution is approximately 50 L (about 0.7 L/kg in a 70 kg adult), indicating moderate tissue distribution, likely into kidney and heart tissues.
Intravenous: 100% bioavailable. Not administered orally (negligible absorption).
Oral bioavailability is about 90–95% in healthy subjects, indicating nearly complete absorption after oral administration. Food does not significantly affect absorption.
For GFR 30-59 m L/min: extend interval to every 12-24 hours; GFR 15-29 m L/min: every 24-48 hours; GFR <15 m L/min (not on dialysis): every 48-96 hours or consider dosing based on serum levels.
e GFR 25-59 m L/min/1.73 m²: Initiate 10 mg once daily; continue 10 mg if tolerated. e GFR <25 m L/min: Not recommended.

Adjust dose based on renal function; monitor serum creatinine and trough levels; usual starting dose: 15 mg/kg/day with extended intervals per renal function.
No specific dose adjustment required; monitor renal function closely.
Aminoglycosides can cause nephrotoxicity and ototoxicity. Neurotoxicity (including vestibular and auditory) may occur even at normal doses. Risk is greater in patients with renal impairment, pre-existing hearing loss, or prolonged use. Monitor renal function and eighth cranial nerve function.

Hypersensitivity to amikacin or other aminoglycosides,Myasthenia gravis (relative due to risk of neuromuscular blockade)
Concomitant use with strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin, ketoconazole, ritonavir).,Addison's disease (adrenal insufficiency).,Serum potassium > 5.0 m Eq/L at initiation.
No clinically significant food interactions. Maintain adequate hydration. Avoid excessive alcohol consumption.
Avoid grapefruit and grapefruit juice as they inhibit CYP3A4 and may increase finerenone exposure. No other food interactions noted.
Aminoglycosides like amikacin cross the placenta. First trimester: No evidence of major malformations, but risk cannot be excluded. Second and third trimesters: Potential for fetal ototoxicity (eighth cranial nerve damage) and nephrotoxicity, especially with high doses or prolonged use. Avoid unless compelling indication.
Based on animal studies, Kerendia (finerenone) is associated with fetal harm. In rats, embryofetal toxicity (reduced fetal weights, delayed ossification) and malformations (cardiovascular, skeletal) were observed at maternal exposures below the maximum recommended human dose. In rabbits, increased post-implantation loss and decreased fetal weights occurred. There are no adequate human studies. Use is contraindicated in pregnancy. Avoid in women of childbearing potential not using effective contraception.
Minimal excretion into breast milk (M/P ratio unknown but expected low). No reports of adverse effects in nursing infants from maternal amikacin use. Caution with infant renal impairment or premature infants due to potential accumulation. Use only if necessary.
No data on presence in human milk, effects on breastfed infant, or milk production. Excreted in rat milk. M/P ratio unknown. Due to potential for serious adverse reactions (e.g., hyperkalemia, hypotension), breastfeeding is not recommended during therapy and for 1 week after last dose.
Increased renal clearance in pregnancy may lower serum levels; consider higher doses based on therapeutic drug monitoring. Adjust for renal impairment if present. Standard initial dosing: 15 mg/kg/day IV/IM divided q8-12h, with level-guided adjustments.
Kerendia is contraindicated in pregnancy. No dose adjustments are provided due to lack of human data; use is not recommended. Pharmacokinetic changes in pregnancy are unknown, but dose modifications are not applicable as therapy should be discontinued if pregnancy occurs.
Amikacin is an aminoglycoside antibiotic with concentration-dependent bactericidal activity. Monitor peak (20-30 mcg/m L) and trough (<10 mcg/m L) serum levels to optimize efficacy and minimize toxicity. Adjust dose based on renal function (Cr Cl). Ototoxicity (vestibular and cochlear) and nephrotoxicity are dose-limiting; audiometry and renal function tests are mandatory. Extended-interval dosing (15-20 mg/kg once daily) is preferred for most indications. Avoid concurrent use with other nephrotoxic drugs (e.g., vancomycin, loop diuretics).
Monitor serum potassium closely, especially in patients with e GFR <30 m L/min/1.73m² or baseline K+ >5.0 m Eq/L. Avoid use with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir). Contraindicated with concomitant mineralocorticoid receptor antagonists (e.g., spironolactone, eplerenone). Use caution with moderate CYP3A4 inhibitors (e.g., erythromycin, verapamil) and moderate CYP3A4 inducers (e.g., rifampin, phenytoin). Assess e GFR and serum potassium before initiation and at 1 month after starting or adjusting dose.
