Clinical study

Clinical study with impressive results1

Fast. Powerful. Well tolerated. Dorithricin® Throat Lozenges have provided effective and long-lasting relief for sore throats and swallowing difficulties for decades. A study1 shows good results and confirms the efficacy, which has already been clinically proven several times2,3,4.

In a clinical study, Dorithricin® impresses with its fast, effective and long-lasting efficacy

In a placebo-controlled, double-blind study1 with more than 300 patients, Dorithricin® once again confirmed its effectiveness and tolerability in the treatment of sore throat.

The study results show:


The efficacy of Dorithricin® was again confirmed by the present placebo-controlled study. Particularly noteworthy is the fact that Dorithricin® not only relieves the symptoms of a sore throat in the short term, but also has a positive effect on the entire course of the disease. In most cases, the course of a sore throat was significantly reduced: after three days, many patients were completely free of symptoms.

Dorithricin®: My fast throat-medicine

Fast. Powerful. Well tolerated.

Thanks to the medically intelligent composition, Dorithricin® has a broad spectrum of activity: Dorithricin® not only provides rapid and lasting pain relief, it also specifically targets bacteria and viruses. In doing so, Dorithricin® slows down the infection before a sore throat gets worse.

The special anaesthetic agent quickly and effectively relieves the nagging sore throat without creating an unpleasant numb feeling in the mouth. The two other active ingredients mutually complement and enhance one another in their anti-infective properties.

Good to know
Dorithricin® Throat Lozenges are well tolerated. Therefore, they are also suitable for children from the age of 2 as soon as they are able to suck on lozenges in a controlled manner.

Dorithricin® Throat Lozenges are also available with a wild-berry flavour – which children* find particularly tasty.

The approved age for Dorithricin® may vary in different countries. Please refer to the local package leaflet or ask your doctor or pharmacist.
