Pharmacokinetics:

Paracetamol(Acetaminophen)

• Absorption:rapidly absorbed from the GIT and is distributed throughout most body tissues.
• the plasma half- life is 1.25 to 3 hours but may increased by liver damage and following overdose.
• Elimination: of Paracetamol(Acetaminophen) is  principally by liver metabolism (conjugation) and subsequent renal excretion of metabolites.

Chlorpheniramine+pseudoephedrine:

• Absorption: Co-administration of Chlorpheniramine and pseudoephedrine doesn’t significantly affect the bioavailability of other component.  
• Distribution: No plasma protein binding data in humans are available.
• Metabolism: 70% of the administered was recovered  in the urine and 10 % in the feces.
• Elimination : the mean elimination half- life of Chlorpheniramine was 7-9 hours and the mean  elimination half- life of pseudoephedrine was 6 hours.

Notes:

Sinusitis: Air trapped within a blocked sinus, along with pus or other secretions (liquid material) may cause pressure on the sinus wall. The result is the sometimes intense pain of a sinus attack. Similarly, when air is prevented from entering a paranasal sinus by a swollen membrane at the opening, vacuum can be created that also causes pain.

Allergic Rhinitis: Allergic rhinitis is a chronic immunoglobulin E–mediated (IgE-mediated) inflammatory disease of the nasal mucosa, a condition that mimics a chronic cold.

Common Cold: A contagious, viral infectious disease of the upper respiratory system, caused primarily by rhinoviruses and corona viruses. Common symptoms include a sore throat, runny nose, headache, nasal congestion and fever.
