Descripción

El costo orientativo de Inyección intravítrea de ranibizumab en hospitales públicos generales de China es de aprox. ¥3150-5200, y en hospitales Clase 3A es de aprox. ¥4500-6500.

Usos Principales

Primary clinical use is intravitreal administration of ranibizumab (a recombinant humanized monoclonal antibody fragment) to inhibit vascular endothelial growth factor-A (VEGF-A) in the eye. Indications include: neovascular (wet) age-related macular degeneration (nAMD), macular edema following retinal vein occlusion (RVO), diabetic macular edema (DME), and myopic choroidal neovascularization (mCNV). Treatment aims to reduce vascular leakage, inhibit abnormal blood vessel growth, stabilize or improve visual acuity, and prevent disease progression.

Rango Normal

Not applicable — anti-VEGF intravitreal injection (ranibizumab) is a therapeutic procedure, not a diagnostic laboratory test with quantitative biomarker values. There is no 'normal range' for ranibizumab concentration in clinical practice; dosing is standardized (0.5 mg/0.05 mL per injection), and systemic drug levels are not routinely monitored.

Valores Bajos - Posibles Causas

N/A — this is not a measurable serum or ocular fluid assay; 'low value' does not apply. However, subtherapeutic effect may result from: 1) Inadequate dosing frequency (e.g., extended dosing intervals beyond disease activity), 2) Poor drug penetration due to vitreous opacities or fibrosis, 3) Development of neutralizing anti-ranibizumab antibodies (rare), 4) Non-adherence to treatment protocol, 5) Underlying disease resistance (e.g., persistent VEGF-independent angiogenesis).

Valores Altos - Posibles Causas

N/A — no clinically defined 'high value' exists. Potential concerns related to excessive exposure include: 1) Off-label repeated injections without evidence-based justification, 2) Accidental overdose (e.g., dosing error — extremely rare with prefilled syringes), 3) Systemic absorption leading to elevated free VEGF inhibition (theoretical risk of hypertension or thromboembolism), 4) Concomitant use of other anti-angiogenic agents, 5) Pre-existing systemic conditions exacerbating anti-VEGF effects (e.g., uncontrolled hypertension, recent stroke).
