Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Androgen receptor agonist; stimulates protein synthesis and growth of androgen-sensitive tissues.
Mannitol is an osmotic diuretic that increases plasma osmolality, drawing water from intracellular spaces into the extracellular fluid and bloodstream, thereby reducing cerebral edema and promoting diuresis. Dextrose provides a source of calories and may help prevent hypoglycemia.
Testosterone replacement therapy for male hypogonadism,Off-label: delayed puberty in males
Reduction of intracranial pressure,Reduction of intraocular pressure,Promotion of diuresis in oliguric acute renal failure (prophylaxis or treatment),Osmotic diuresis for drug overdose (e.g., salicylates, barbiturates),Irrigation solution during transurethral prostatic resection
2.5-10 mg orally once daily in the morning for androgen replacement therapy in adult males.
Adult: 50-100 g (500-1000 m L of 10% solution) intravenously over 1-2 hours, repeated as needed every 6-12 hours. Individualize based on urine output and serum osmolality.
Terminal elimination half-life is 3.5–5.5 hours; clinical effects may persist for several days due to active metabolites.
Terminal elimination half-life of mannitol is approximately 1.5-2 hours in patients with normal renal function. Clinically, duration of osmotic diuresis parallels half-life; in renal impairment, half-life may extend to 24-36 hours, increasing risk of fluid overload and electrolyte disturbances.
Hepatic via CYP3A4 and CYP2B6; undergoes first-pass metabolism.
Mannitol is not significantly metabolized; it is excreted unchanged by the kidneys. Dextrose is metabolized via glycolysis to pyruvate and lactic acid, and enters the Krebs cycle for energy production.
Primarily renal: ~90% as glucuronide and sulfate conjugates, 6% as unchanged drug; ~5% fecal via bile.
Primarily renal excretion: Mannitol is filtered by glomeruli and not reabsorbed, excreted unchanged in urine (approximately 80-90% within 24 hours). Biliary/fecal elimination is negligible (<5%). Dextrose is metabolized to CO2 and water; any excess is excreted renally as glucose if threshold exceeded.
98% bound to sex hormone-binding globulin (SHBG) and albumin.
Mannitol is not significantly bound to plasma proteins (<1%). Dextrose is not protein bound.
Vd approximately 1.0 L/kg; indicates extensive tissue distribution, especially to reproductive organs and bone marrow.
Approximately 0.5-0.6 L/kg. Mannitol distributes primarily in extracellular fluid (ECF); it does not enter cells significantly. Clinically, this low Vd indicates confinement to ECF, important for osmotic effects.
Oral: 15–25% due to first-pass metabolism; buccal or transdermal: higher, but not commercially available for this formulation.
Intravenous: 100% bioavailability. Oral bioavailability is negligible (<10%) as mannitol is poorly absorbed and acts as an osmotic laxative; Dextrose is well absorbed orally (100%) but not relevant for this IV formulation.
No specific dose adjustment required based on GFR; caution in severe impairment (Cr Cl <30 m L/min) due to potential fluid retention.
Contraindicated in anuria or severe renal impairment (GFR < 20 m L/min). For GFR 20-50 m L/min, use with caution and monitor serum osmolality; reduce dose or extend interval. No specific dose reduction formula established.
Contraindicated in Child-Pugh class B and C cirrhosis due to hepatotoxicity risk; in class A, use with caution and monitor liver function.
No specific adjustments required for hepatic impairment. Monitor fluid and electrolyte balance due to potential volume expansion.
Not recommended for use in children as it may cause premature epiphyseal closure and virilization; limited data.
0.25-1 g/kg (2.5-10 m L/kg of 10% solution) intravenously over 30-60 minutes, repeated as needed. Max dose 2 g/kg/day. Adjust based on response and serum osmolality.
Increased risk of prostatic hyperplasia and carcinoma; use lowest effective dose with regular prostate monitoring.
Use lower initial doses and monitor renal function and electrolytes closely due to age-related decline in renal function and higher risk of volume overload. Start at 25-50 g (250-500 m L of 10% solution) and titrate.
Warning: Prolonged use may cause virilization in women, premature epiphyseal closure, and increased risk of prostatic hypertrophy/carcinoma.
None.
Monitor liver function, lipid profile, and prostate-specific antigen; risk of edema in patients with cardiac disease; avoid use in patients with sleep apnea.
Monitor serum electrolytes, osmolality, and renal function during therapy,May cause fluid and electrolyte imbalances, including hyponatremia or hypernatremia,Administer cautiously in patients with renal impairment, heart failure, or pulmonary edema,Use with caution in conditions where increased intravascular volume may be harmful,Do not administer if solution contains particulate matter or is discolored
Known or suspected prostate cancer; breast cancer in males; hypersensitivity to androgens; pregnancy and lactation.
Anuria due to severe renal disease,Severe dehydration,Intracranial hemorrhage (unless during craniotomy),Active intracranial bleeding except during craniotomy,Hypersensitivity to mannitol or dextrose,Congestive heart failure,Pulmonary edema
Avoid grapefruit and grapefruit juice as they may increase drug levels. Limit salt intake to reduce fluid retention. Alcohol may increase risk of liver toxicity.
No clinically relevant food interactions.
Pregnancy Category X. ANDROID 5 (oxandrolone) is contraindicated in pregnancy due to teratogenic effects including masculinization of female fetus, clitoral enlargement, and labial fusion. Risk is highest during first trimester but applies throughout gestation.
No evidence of teratogenicity in animal studies; limited human data. Mannitol crosses the placenta; risk of fetal electrolyte disturbances and dehydration with maternal overdose. First trimester: theoretical risk only, no reported malformations. Second/third trimesters: monitor for maternal hyperosmolality and fluid shifts which may affect fetal hydration status.
Excretion into human milk is unknown. Due to potential for androgenic effects in nursing infants, breastfeeding is not recommended. No M/P ratio available.
Not known if mannitol or dextrose are excreted in breast milk. Consider risk of osmotic diarrhea in neonate if present in milk. M/P ratio not established.
Not applicable; contraindicated in pregnancy. No dose adjustment recommendations exist for pregnant patients.
No specific dose adjustment recommended; monitor maternal fluid status closely as pregnancy increases risk of pulmonary edema; adjust rate based on urine output and osmolality.
Android 5 (methyltestosterone) is an androgenic anabolic steroid used for hypogonadism and delayed puberty. Monitor liver function due to hepatotoxicity. Use with caution in elderly due to increased risk of prostatic hypertrophy and carcinoma. Can cause fluid retention in patients with cardiac, renal, or hepatic disease. Avoid in patients with breast cancer or known or suspected prostate cancer.
Monitor serum sodium and osmolality closely; risk of hypernatremia and acute kidney injury. Use an in-line filter to prevent crystallization. Administer by slow IV infusion to avoid fluid overload. Contraindicated in anuria and severe pulmonary edema.

No interactions on record
"Concomitant use of clonidine and mannitol may potentiate the hypotensive effect of clonidine, leading to an increased risk of severe hypotension, syncope, and orthostatic hypotension. Mannitol, an osmotic diuretic, can cause volume depletion and electrolyte disturbances, which may exacerbate clonidine's sympatholytic effects on blood pressure regulation. This interaction is particularly concerning in patients with pre-existing cardiovascular conditions or those receiving other antihypertensive agents."
"Mannitol, an osmotic diuretic, induces intravascular volume expansion followed by diuresis, which can cause electrolyte disturbances, particularly hypokalemia and hypomagnesemia. Nifedipine, a calcium channel blocker, can further lower blood pressure through vasodilation. The combination may enhance the hypotensive effect and increase the risk of arrhythmias due to electrolyte imbalances."
"Coadministration of candesartan cilexetil, an angiotensin II receptor blocker (ARB), with mannitol, an osmotic diuretic, can result in an additive hypotensive effect due to overlapping mechanisms that reduce blood pressure. Mannitol increases renal water excretion, decreasing plasma volume and preload, while candesartan inhibits angiotensin II-mediated vasoconstriction and aldosterone secretion, leading to vasodilation and reduced afterload. This combined effect may predispose patients to symptomatic hypotension, especially in those with volume depletion or renal impairment."
