There has been no experience of overdosage with Imunovir. However serious adverse effects apart from increased levels of uric acid in the body, seem unlikely in view of the animal toxicity studies. Treatment should be restricted to symptomatic and supportive measures.
5. Pharmacological Properties
5.1 Pharmacodynamic Properties
Imunovir is an agent demonstrating anti-viral activity and possessing immunopotentiating action in viral diseases.
5.2 Pharmacokinetic Properties
Following a single oral dose of inosine acedoben dimeparanol, peak plasma conditions of inosine occur after 1 hour. However, 2 hours after administration, plasma concentrations decrease to undetectable amounts. Inosine acedoben dimeparanol has a very short plasma half-life of 50 minutes following an oral dose. The major excretion product of the inosine moiety is uric acid, while the p-acetamidobenzoic acid and N,N-dimethylamino-2-propanol components are excreted in the urine as glucuronidated and oxidised products, respectively, as well as being excreted unchanged.
5.3 Preclinical Safety Data
There is no pre-clinical data of relevance to the prescriber which is additional to that included in other sections of the SPC.
