Pharmacodynamics
Oplex is a combination of substances which contains an antihistamine, antitussive and sedative (Oxomemazine), two expectorants (Guaifenesin and Sodium benzoate) and antipyretics (Paracetamol).

Pharmacokinetics
Guaifenesin is absorbed from the gastrointestinal tract. It is metabolized and then excreted in the urine.
Paracetamol is readily absorbed from the gastrointestinal tract with peak plasma concentrations occurring about 10 to 60 minutes after oral doses and is distributed into most body tissues. It crosses the placenta and is present in breast milk. Paracetamol is metabolised predominantly in the liver and excreted in the urine mainly as the glucuronide and sulfate conjugates. Less than 5% is excreted as unchanged paracetamol.
Sodium benzoate is absorbed from the gastrointestinal tract and conjugated with glycine in the liver to from hippuric acid, which is rapidly excreted in the urine.
