Dosage

Children: There are no specific dosing guidelines for currants in children. They can be introduced into the diet according to age-appropriate recommendations.

Adults: There are no specific dosing guidelines for currants. They can be consumed in varying amounts as part of a balanced diet.

Mechanism of action

The health benefits of currants are largely attributed to their high content of anthocyanins, flavonoids, and vitamin C. These compounds exhibit antioxidant properties, which help in neutralizing free radicals in the body, thus reducing oxidative stress. Additionally, vitamin C is crucial for collagen synthesis and plays a significant role in the immune response.

Pharmacodynamics

The pharmacodynamic effects of currants are mainly due to their bioactive compounds. Anthocyanins enhance endothelial function and may improve blood circulation, while vitamin C is essential for immune function and acts as an antioxidant. The flavonoids present in currants also have anti-inflammatory properties, which can contribute to overall health.

Pharmacokinetics

The pharmacokinetics of currants is not well-documented in the literature, but it is known that their bioactive compounds are absorbed in the gastrointestinal tract. Once ingested, these compounds may undergo metabolic transformations in the liver before exerting their effects in the body. The elimination half-life of these compounds can vary based on individual metabolism and the form of currant consumed.

Pregnancy

Currants are generally considered safe to consume during pregnancy as they are a natural food source rich in vitamins and minerals. However, excessive intake should be avoided due to potential effects on blood sugar levels.

Breast-feeding

Currants can be consumed during breastfeeding as they are a nutritious food; however, moderation is advised to avoid any gastrointestinal discomfort in the infant.

Storage

Store currants in a cool, dry place. If fresh, refrigerate and consume within a few days. Dried currants should be kept in an airtight container to maintain freshness.

Formulations

• Fresh currants
• Dried currants
• Currant juice
• Currant jams or jellies

Indications

• Sore throat
• Dry cough
• Oral mucosal irritation
• Mild throat infections
• Local anesthetic effect

Dosage

Children: Refer to the BNF for Children for specific dosing information based on the child's age and weight, as lozenge formulations can differ significantly in active ingredient concentrations.

Adults: Refer to specific product labeling for dosage instructions, as lozenges can vary widely in formulation and strength. Generally, they are used as needed, with a typical recommendation being to dissolve one lozenge in the mouth every 2 to 4 hours.

Mechanism of action

Lozenges act primarily through local effects in the oral cavity. Ingredients like menthol produce a cooling sensation and can soothe irritation in the throat. Benzocaine acts as a local anesthetic by blocking sodium channels in the neuronal cell membrane, preventing the propagation of nerve impulses and thereby reducing the sensation of pain. Antiseptic components can help in reducing microbial load in the throat.

Pharmacodynamics

The pharmacodynamic effects of lozenges depend on their active ingredients. For instance, menthol can cause a sensation of cooling, which can alleviate discomfort, while benzocaine provides analgesia. Antiseptics can reduce inflammation and inhibit pathogen growth in the throat, contributing to symptomatic relief. The duration of these effects may vary based on the specific formulation and the rate of dissolution in saliva.

Pharmacokinetics

When lozenges dissolve in the mouth, the active ingredients are absorbed through the mucosal membranes of the oral cavity. Systemic absorption may occur but is generally minimal due to the localized application. The onset of action is usually rapid, providing quick relief, while the duration of effect can last from 30 minutes to several hours, depending on the formulation and the individual’s saliva production.

Adverse effects

• local irritation
• allergic reactions
• nausea

Precautions

• use with caution in patients with a history of allergies to any ingredients
• should be used with caution in patients with certain medical conditions affecting swallowing

Pregnancy

Lozenges are generally considered safe to use during pregnancy, but it is advisable to consult a healthcare provider before use.

Breast-feeding

Lozenges are typically safe during breastfeeding, but it is recommended to check with a healthcare provider.

Storage

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

Formulations

• sugar-free lozenges
• medicated lozenges
• herbal lozenges

Indications

• Providing energy in dietary supplementation
• Enhancing flavor in food products
• Replacement of carbohydrates in certain medical nutrition therapies

Dosage

Children: Refer to general dietary guidelines for carbohydrate intake in children. No specific dosing guidelines provided.

Adults: Refer to general dietary guidelines for carbohydrate intake. No specific dosing guidelines provided.

Mechanism of action

Sugar is metabolized in the body to provide energy. Upon ingestion, sucrose is broken down by the enzyme sucrase into its constituent monosaccharides, glucose and fructose, which are then absorbed into the bloodstream. These monosaccharides can be utilized by cells for energy or stored as glycogen in the liver and muscles.

Pharmacodynamics

As a simple carbohydrate, sugar elevates blood glucose levels rapidly after consumption, leading to increased insulin secretion from the pancreas. This insulin facilitates the uptake of glucose by tissues, promoting energy production. The rapid increase in blood sugar can provide quick energy but may also lead to potential negative effects on metabolism and weight if consumed in excess.

Pharmacokinetics

After oral administration, sugar is quickly hydrolyzed in the gastrointestinal tract. Peak plasma glucose concentrations typically occur within 30 minutes to 2 hours post-ingestion, depending on the amount consumed and individual metabolism. The half-life of glucose in the bloodstream is relatively short, as it is rapidly taken up by tissues or converted into glycogen.

Pregnancy

Sugar is generally considered safe for use during pregnancy, but excessive intake should be avoided to prevent gestational diabetes and excessive weight gain.

Breast-feeding

Sugar is safe during breastfeeding; however, excessive consumption should be avoided.

Storage

Store in a cool, dry place, away from moisture and direct sunlight.

Formulations

• Granulated sugar
• Brown sugar

Indications

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

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.
