Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Mannitol is an osmotic diuretic that increases plasma osmolarity, drawing water from tissues into the bloodstream and enhancing water excretion by the kidneys. It also reduces intracranial pressure by creating an osmotic gradient across the blood-brain barrier.
Android 25 contains methyltestosterone, a synthetic androgen that binds to androgen receptors, promoting protein synthesis and anabolic effects. It also inhibits gonadotropin secretion from the pituitary, reducing endogenous testosterone production.

Adults: 50-100 g intravenously over 30-60 minutes, typically as a 15-25% solution. For reduction of intracranial pressure, 1.5-2 g/kg as a 20% solution IV over 30-60 minutes. For promotion of diuresis, 50-100 g as a 5-25% solution IV.
Testosterone 25 mg subcutaneously or intramuscularly every 2 to 4 weeks. Alternatively, 125 mg intramuscularly every 10 days.
Terminal elimination half-life is 0.25–1.5 hours; prolonged in renal impairment (up to 36 hours).
Terminal elimination half-life: 10–100 minutes (testosterone); clinical context: rapid clearance necessitates frequent dosing or use of esters for sustained effect
Mannitol is not metabolized; it is excreted unchanged by the kidneys via glomerular filtration.
Primarily hepatic via reduction and oxidation; metabolites include androsterone and etiocholanolone; excreted in urine.
Renal: >90% as unchanged drug; minimal biliary or fecal excretion.
Renal: 90% (as glucuronide and sulfate conjugates, 5–10% unchanged); fecal/biliary: 10%
Negligible (<0.1%); no specific binding proteins.
97–99% (sex hormone-binding globulin and albumin)
0.2–0.5 L/kg; primarily confined to extracellular fluid; increases with dehydration.
0.3–0.6 L/kg; indicates distribution into lean muscle and sex organs
IV: 100%; oral: <10% due to poor absorption.
Oral: <5% (methyltestosterone: ~20–25% due to 17α-alkylation); IM: 100%
Contraindicated in anuria or severe renal impairment (GFR < 20 m L/min). For GFR 20-50 m L/min, reduce dose by 50% and monitor serum osmolarity and urine output. No specific dose for GFR >50 m L/min.
No dose adjustment required for GFR ≥30 m L/min. For GFR <30 m L/min, consider reducing dose or increasing interval; monitor for fluid retention and hypertension.
No specific dose adjustment for hepatic impairment. Caution in patients with cirrhosis due to risk of fluid overload.
Contraindicated in Child-Pugh class B or C cirrhosis. For mild hepatic impairment (Child-Pugh A), start with lower dose (e.g., 12.5 mg every 2 weeks) and titrate based on response and liver function.
Children: For reduction of intracranial pressure, 0.25-1 g/kg as a 15-25% solution IV over 30-60 minutes. For diuresis, 0.5-2 g/kg as a 5-25% solution IV every 6-12 hours. Maximum dose 2 g/kg/dose.
Not recommended for use in pediatric patients (safety and efficacy not established). For male adolescents with hypogonadism, individualize: start at 12.5 mg every 2 weeks and adjust based on testosterone levels and growth.
Elderly: Use lower doses and titrate carefully due to increased risk of fluid overload, electrolyte disturbances, and renal impairment. Monitor renal function and serum osmolarity. Start with the lower end of adult dosing range.
Start with lower initial dose (e.g., 12.5 mg every 2 weeks); monitor prostate-specific antigen (PSA) and hematocrit frequently. Avoid in patients with prostate cancer or untreated sleep apnea.
None

Known or suspected prostate cancer; male breast cancer; pregnancy; lactation; hypersensitivity to methyltestosterone; severe hepatic impairment.
No significant food interactions; maintain adequate hydration unless contraindicated.
Take with food containing fat (e.g., avocado, nuts, olive oil) to enhance absorption. Avoid grapefruit juice as it may increase testosterone levels via CYP3A4 inhibition. Limit alcohol due to potential liver effects.
Mannitol 10% is a hyperosmolar agent. Limited human data. No known teratogenic effects reported in animal studies. Fetal risk cannot be excluded; use only if clearly needed. First trimester: theoretical risk from osmotic shifts. Second/third trimester: monitor for maternal hemodynamic changes (e.g., pulmonary edema) that may affect placental perfusion.
Android 25 (methyltestosterone) is an androgen. First trimester: Virilization of female fetus, including clitoromegaly, labial fusion, urogenital sinus abnormalities if exposure occurs before 12 weeks gestation. Second and third trimesters: Continued risk of female pseudohermaphroditism, and potential for masculinization of female external genitalia. Androgens can cross the placenta and may also cause skeletal abnormalities and growth retardation. Pregnancy category X.
Unknown if excreted in human milk. No available data on M/P ratio. Consider benefits of breastfeeding vs. potential risk of osmotic effects or maternal dehydration. Caution advised.
Methyltestosterone is excreted into breast milk; M/P ratio not established. May cause virilization in female infants and premature sexual development in male infants. Androgens can suppress lactation. Use during breastfeeding is contraindicated.
No specific dose adjustments recommended for pregnancy alone. Consider increased plasma volume in pregnancy; monitor for volume overload. Dose based on clinical response and renal function. Avoid rapid infusion.
Android 25 is contraindicated in pregnancy, so no dosing adjustments are applicable. If used inadvertently, discontinue immediately. No pharmacokinetic data to guide dose changes; avoid use entirely.

"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."
