Dosage

Children: Refer to the BNF for Children for specific dosing information based on the selected medication and age of the child.

Adults: Refer to the BNF for specific dosing information based on the selected medication and indication for cough.

Mechanism of action

Cough medications can act through various mechanisms depending on their classification. Cough suppressants (antitussives) like dextromethorphan inhibit the cough reflex in the brain, while expectorants like guaifenesin increase mucus secretion, making it easier to expel. Mucolytics, such as acetylcysteine, break down mucus structure, facilitating clearance from the airways.

Pharmacodynamics

The pharmacodynamics of cough medications vary widely. Antitussives primarily reduce the sensitivity of the cough reflex pathways in the central nervous system. Expectorants promote increased mucus production and reduce viscosity, aiding in expectoration. Mucolytics alter the physical properties of mucus, enhancing its clearance from the respiratory tract.

Pharmacokinetics

The pharmacokinetics of cough medications differ among classes. Antitussives are generally well-absorbed orally, with peak plasma concentrations occurring within 1-2 hours. They are metabolized in the liver and excreted primarily through urine. Expectorants and mucolytics also exhibit similar absorption profiles and are eliminated through renal pathways, although their metabolism may involve different enzymatic processes in the liver.

Dosage

Children: Pediatric dosing of herbal remedies is highly variable and should be determined by a healthcare professional knowledgeable in herbal medicine. It is essential to refer to specific guidelines or clinical resources.

Adults: Dosage of herbal medicines can vary widely based on the specific herb and formulation. It is important to refer to trusted herbal medicine guidelines or consult with qualified practitioners.

Mechanism of action

The mechanisms of action of herbal medicines can vary significantly based on the specific herb and its active constituents. Many herbs contain phytochemicals that can modulate biological pathways, including anti-inflammatory, antioxidant, and antimicrobial effects. Some herbs may influence neurotransmitter systems, immune responses, or hormonal activity, contributing to their therapeutic effects.

Pharmacodynamics

Pharmacodynamics of herbal medicines involves the interaction of their active components with biological systems. These compounds can bind to receptors, inhibit enzymes, or alter cellular signaling pathways. For example, flavonoids found in many herbs may exert antioxidant effects by scavenging free radicals, while alkaloids may interact with neurotransmitter receptors to influence mood or pain perception. The overall impact on physiological processes can lead to therapeutic benefits, but also potential side effects.

Pharmacokinetics

The pharmacokinetics of herbal medicines encompass absorption, distribution, metabolism, and excretion of the active components. Many herbal compounds are absorbed in the gastrointestinal tract and undergo first-pass metabolism in the liver. The bioavailability of these compounds can be affected by factors such as the formulation, presence of other food substances, and individual patient metabolism. Elimination may occur through urine or feces, and the duration of action can vary based on the herb and preparation.

Pregnancy

Consult a healthcare provider before use, as the safety of herbal products during pregnancy can vary greatly depending on the specific herb.

Breast-feeding

Consult a healthcare provider before use, as many herbal products may not be safe during breastfeeding.

Storage

Store in a cool, dry place, away from direct sunlight and moisture. Keep out of reach of children.

Indications

• Common cold
• Seasonal allergic rhinitis
• Non-allergic rhinitis
• Sinusitis
• Flu symptoms

Dosage

Children: Refer to specific product guidelines for dosing instructions for children, as it may differ based on age and weight.

Adults: Refer to specific product guidelines for dosing instructions, as it may vary by formulation.

Mechanism of action

Travisil's active components work by blocking histamine receptors, leading to a reduction in allergy symptoms. The decongestant component causes vasoconstriction of nasal blood vessels, decreasing swelling and congestion. The cough suppressant acts centrally to reduce the cough reflex, alleviating the urge to cough.

Pharmacodynamics

The antihistaminic effects reduce the physiological responses to histamine, such as vasodilation and increased vascular permeability. The decongestant properties relieve nasal congestion by causing blood vessel constriction in the nasal passages. The cough suppressant decreases the activity of the cough center in the brain, which results in reduced coughing. These combined effects help improve overall patient comfort during respiratory infections.

Pharmacokinetics

The pharmacokinetics of Travisil's components can vary, but generally, antihistamines are rapidly absorbed, with peak plasma concentrations occurring within a few hours. The duration of action typically ranges from 4 to 12 hours, depending on the specific antihistamine used. Decongestants are also absorbed quickly, with a similar duration of effect. Metabolism usually occurs in the liver, and elimination is primarily renal, with both unchanged drug and metabolites excreted in urine.
