Up to 80% of sore throats are caused by viruses. Several over the counter
products are available which provide symptomatic, not causal relief. For such
lozenges, containing the antiseptics and local anesthetics amylmetacresol (AMC)
and 2,4-dichlorobenzyl alcohol (DCBA) or hexylresorcinol (HR), recently an
additional virucidal effect was published. Therefore, we tested a set of
Strepsils(®) lozenges, containing either HR (Max [#2]) or AMC/DCBA (Original
[#3], Extra Strong [#4], Warm [#5], Orange and Vitamin C [#6], Sugar free Lemon
[#7], Children/Strawberry [#8] and Soothing Honey and Lemon [#9]) for their
antiviral efficiency against representatives of respiratory viruses known to
cause sore throat: human rhinovirus (HRV) 1a, HRV8, influenza virus A H1N1n,
Coxsackievirus A10, and human coronavirus (hCoV) OC43. The lozenges were tested
head to head with Coldamaris(®) lozenges (#1), which contain the patented
antiviral iota-carrageenan. None of the tested AMC/DCBA or HR containing lozenges
shows any antiviral effectiveness against HRV8 at the tested concentrations,
whereas all are moderately active against HRV1a. Only lozenge #5 shows any
activity against hCoV OC43 and Coxsackievirus A10 at the tested concentrations.
Similarly, only lozenge #3 is moderately active against influenza A H1N1n virus.
The data indicates that neither the isolated effect of the active ingredients nor
the pH but rather one or more of the excipients of the specific formulations are
responsible for the antiviral effect of some of the AMC/DCBA or HR containing
lozenges. In contrast, carrageenan-containing lozenges are highly active against
all viruses tested. In another experiment, we showed that binding and
inactivation of virus particles by iota-carrageenan are fast and highly
effective. During the residence time of the lozenge in the mouth, the viral titer
is reduced by 85% and 91% for influenza A virus and hCoV OC43, respectively.
Carrageenan-containing lozenges are, therefore, suitable as causative therapy
against viral infections of the throat.
