- Paracetamol: Analgesic and antipyretic
- Phenylephrine: Nasal decongestant
- Zinc Gluconate: Immune system modulator and antiviral
Mechanism of Action: The combined action of the ingredients targets various aspects of cold and allergy symptoms:
- Ambroxol: Reduces mucus viscosity, aiding expectoration.
- Desloratadine: Blocks histamine H1-receptors, mitigating allergic reactions.
- Paracetamol: Inhibits prostaglandin synthesis, reducing fever and pain.
- Phenylephrine: Constricts nasal blood vessels, relieving congestion.
- Zinc Gluconate: Supports immune function and exhibits some antiviral properties.

How It Works
Pharmacodynamics: The combined effects of the components produce symptomatic relief from cold and allergy symptoms.
Pharmacokinetics:
- Absorption: Each component has its own absorption profile; generally absorbed from the gastrointestinal tract.
- Metabolism: Primarily hepatic metabolism, with some renal excretion.
- Elimination: Primarily via urine, with some fecal excretion
Mode of Action:
- Ambroxol: Breaks down mucopolysaccharide fibers in mucus.
- Desloratadine: Competitively antagonizes histamine at H1 receptors.
- Paracetamol: Inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis.
- Phenylephrine: Stimulates alpha-adrenergic receptors in nasal mucosa.
- Zinc Gluconate: Influences immune cell activity and viral replication.
Elimination Pathways: Primarily renal and hepatic.
