THERAPEUTIC GROUP: Nasal decongestants and other preparations for topical use

Indications Silver Protein

Proteinated Silver is used as an ear antiseptic, topical antiseptic and nasal decongestant

Mechanism of action Silver protein

Protein silver, often called vitellin silver, is an active ingredient consisting of organic molecules and silver ions used successfully in the clinical setting both as an antiseptic and as a decongestant of the nasal mucosa.
The mostly bacteriostatic effect is determined by the ability of this molecule to inhibit bacterial replication by exerting a visible pro-oxidant effect, such as to alter the normal metabolic capacity of the microorganism, firstly inducing the blocking of replication processes and subsequently its death.
The decongestant effect, on the other hand, has not yet been fully clarified, although the ability to determine a precipitation of the serum exudate proteins is hypothesized, resulting in a better compartmentalization of the water state and a reduction in associated edema.
All this is facilitated by the good pharmacokinetic properties of the silver proteinate, which limit the systemic absorption of the ion and the potential side effects.

Studies carried out and clinical efficacy

All the studies relating to the efficacy of colloidal silver in the clinical setting are particularly dated, demonstrating the common use of this active ingredient in clinical practice.
Despite this, recent scientific evidence, some of which published below, demonstrates the new potential uses of Silver in medicine, dispelling some myths and opening instead therapeutic perspectives of particular clinical interest.

It is also advisable to keep the drug out of the reach of children, to avoid its inappropriate use and potentially very dangerous ingestion.


The use of silver protein in pregnancy and lactation should be limited to cases of real need and obviously supervised by your gynecologist.


No drug interactions worthy of clinical note are currently known.

Contraindications Silver Protein

The use of Silver Protein is contraindicated in patients hypersensitive to the active ingredient or to structurally related drugs.

Undesirable Effects - Side Effects

The use of silver protein, especially if prolonged over time, could determine the onset of local adverse reactions such as burning, redness and pain.
