Usage
This combination medication is primarily prescribed for the symptomatic relief of the common cold and flu. It targets multiple symptoms including nasal congestion, runny nose, sneezing, headache, body aches, fever, cough, and sore throat.
Pharmacological Classification: This combination drug encompasses multiple pharmacological classes:
- Mucolytic: Ambroxol
- Antihistamine: Levocetirizine
- Analgesic and Antipyretic: Paracetamol
- Decongestant: Pseudoephedrine
Mechanism of Action: The components work synergistically to alleviate cold and flu symptoms. Ambroxol reduces mucus viscosity. Levocetirizine blocks histamine receptors, reducing allergic symptoms. Paracetamol inhibits prostaglandin synthesis, lowering fever and pain. Pseudoephedrine constricts nasal blood vessels, relieving congestion.
Alternate Names
This combination medication is often marketed under various brand names (e.g., Festa, Lv Plus) depending on the region and manufacturer. There is no established non-proprietary name for this specific combination. Sometimes, it is referred to as quadruple therapy for cold and flu symptoms.
How It Works
Pharmacodynamics: Ambroxol breaks down mucopolysaccharides, thinning and loosening mucus. Levocetirizine selectively blocks peripheral H1 receptors, reducing histamine-mediated allergic responses. Paracetamol’s mechanism for reducing fever and pain isn’t fully understood, but it is thought to involve inhibition of prostaglandin synthesis in the central nervous system. Pseudoephedrine acts as an alpha-adrenergic agonist, causing vasoconstriction in the nasal mucosa, reducing congestion.
Pharmacokinetics: The pharmacokinetic parameters for this specific combination aren’t routinely evaluated, though individual drug profiles are available. Levocetirizine is rapidly absorbed and undergoes minimal metabolism, primarily excreted renally. Paracetamol is also rapidly absorbed and extensively metabolized in the liver, with primarily renal elimination. Ambroxol is well absorbed orally and metabolized in the liver. Pseudoephedrine is well absorbed and partially metabolized in the liver.
Receptor Binding, Enzyme Inhibition, or Neurotransmitter Modulation: Levocetirizine selectively binds to H1 receptors. Pseudoephedrine activates alpha-adrenergic receptors. Paracetamol’s mechanism may involve COX enzyme inhibition, though this is not definitively established.
Elimination Pathways: Levocetirizine is primarily excreted unchanged in urine. Paracetamol is primarily eliminated in the urine as glucuronide and sulfate conjugates. Ambroxol is primarily excreted in the urine as metabolites. Pseudoephedrine is partially metabolized and excreted in the urine.
Dosage
Dosage must be adjusted to individual patient needs and verified with reputable sources.
