Ritonavir

Very Low Risk for breastfeeding


Safe. Compatible.
Minimal risk for breastfeeding and infant.

Antivírico inhibidor de la proteasa del VIH. Utilizado, solo o potenciando al Lopinavir, en el tratamento del VIH/SiDA.
Se ha empleado de modo experimental en el tratamiento de la infección por coronavirus COVID-19 (Li 2020, Lim 2020, SEFH 2020).

Administración oral en dos dosis al día.

Sus datos farmacocinéticos (peso molecular moderadamente elevado y muy alto porcentaje de fijación a proteínas) explican el ínfimo paso a leche observado (Corbett 2014, Palombi 2012).
Los niveles en plasma de lactantes cuyas madres lo tomaban fueron indetectables (Corbett 2014) o muy bajos (Gandhi 2013, Palombi 2012).

Según la política adoptada en cada país, la lactancia materna en madres con VIH / SIDA está o no aconsejada. Con el tratamiento antirretroviral de gran actividad (TARGA) la carga viral para VIH se puede reducir a cero, reduciendo el riesgo de transmisión de VIH a través de la lactancia materna a niveles semejantes a los de la alimentación con fórmula artificial.

Alternatives

We do not have alternatives for Ritonavir since it is relatively safe.

It is not intended to replace the relationship you have with your doctor but to compound it.

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
