Pyodine Sugical Scrub

Indications

• Hyperlipidemia
• Dyslipidemia
• Mixed dyslipidemia
• High triglyceride levels

Dosage

Children: Refer to the BNF for Children for appropriate dosing information in paediatric patients.

Adults: Refer to the BNF for specific dosing guidelines based on the clinical condition being treated.

Mechanism of action

Fenopan activates PPAR-alpha, a nuclear receptor that regulates the transcription of genes involved in fatty acid oxidation and lipoprotein metabolism. This activation leads to an increase in the oxidation of fatty acids, a reduction in triglyceride synthesis, and an increase in the clearance of triglyceride-rich lipoproteins from the bloodstream. As a result, fenofibrate effectively lowers triglyceride levels and raises HDL cholesterol levels.

Pharmacodynamics

The pharmacodynamics of fenopan include its effects on lipid metabolism and its ability to lower triglycerides and LDL cholesterol while increasing HDL cholesterol. Its action on PPAR-alpha enhances the catabolism of fatty acids and promotes lipoprotein lipase activity, leading to improved overall lipid profiles. These changes contribute to a reduced risk of cardiovascular diseases associated with dyslipidemia.

Pharmacokinetics

Fenopan is well-absorbed from the gastrointestinal tract, with peak plasma concentrations occurring within several hours after oral administration. It is extensively metabolized in the liver, primarily via ester hydrolysis to its active metabolite fenofibric acid. The elimination half-life is approximately 20 hours, and the drug is primarily excreted through the kidneys. Food intake can influence the bioavailability of fenofibrate, which is why it is often recommended to be taken with meals.

Pregnancy

Fenopan should only be used in pregnancy if the benefits outweigh the risks, as safety has not been established.

Breast-feeding

Use with caution while breastfeeding, as it is unclear if fenopan passes into breast milk.

Storage

Store at room temperature, away from moisture and heat.

Dosage

Children: Refer to specific guidelines for pediatric dosing; consult the BNF for Children for accurate dosage information.

Adults: Refer to specific guidelines for use; dosage may vary based on the context of use.

Mechanism of action

Hydroxide ions act primarily as bases, neutralizing acids to form water and salts. They participate in various biochemical pathways, including selenium metabolism and the degradation of reactive oxygen species. Hydroxide can influence enzyme activity and stability by altering the pH of the environment, thereby affecting metabolic reactions.

Pharmacodynamics

Hydroxide ions can impact biological processes by changing the local pH, which influences enzyme activity, ion transport, and the solubility of other compounds. Their ability to neutralize acids can help regulate physiological pH, contributing to homeostasis in living organisms.

Pharmacokinetics

As an inorganic ion, hydroxide does not undergo traditional pharmacokinetic processes like absorption, distribution, metabolism, or excretion. Instead, it is rapidly equilibrated in biological fluids and participates in acid-base reactions, having immediate effects on the local environment.

Pregnancy

There is limited information regarding the use of hydroxide during pregnancy. Consult a healthcare professional for advice.

Breast-feeding

Limited data is available on the excretion of hydroxide in breast milk. Consult a healthcare professional before use.

Storage

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

Indications

• Iodine deficiency
• Goiter
• Hypothyroidism
• Thyroiditis
• Fibrocystic breast disease

Dosage

Children: Refer to the BNF for Children for appropriate dosing guidelines based on age and weight.

Adults: Refer to the BNF for appropriate dosing guidelines based on condition and clinical judgment.

Mechanism of action

Molecular iodine inhibits the induction and promotion of carcinogenesis in mammary tissues and has shown beneficial effects in fibrocystic breast disease. It temporarily decreases thyroid hormone production through the acute Wolff-Chaikoff effect, followed by a return to normal hormone synthesis due to down regulation of the sodium-iodide symport. This mechanism can lead to a transient hypothyroid state in some individuals with underlying thyroid conditions.

Pharmacodynamics

Iodine is vital for the synthesis of thyroid hormones thyroxine (T4) and triiodothyronine (T3). It affects the metabolism of amine-derived hormones and plays a role in amino acid metabolism. The acute excess of iodide can lead to decreased circulating levels of T4 and T3 in susceptible individuals, while most people can escape this effect and maintain normal thyroid function.

Pharmacokinetics

Iodine is absorbed primarily in the gastrointestinal tract and is distributed throughout the body, particularly in the thyroid gland, where it is concentrated for hormone synthesis. The kidney plays a significant role in the excretion of excess iodine. The half-life of iodine in the body varies and can be influenced by dietary intake and underlying health conditions.

Adverse effects

Mechanism of action

Povidone acts by forming a complex with iodine when used as an antiseptic, which releases iodine slowly to exert its antimicrobial effect. The iodine disrupts microbial cell walls and interferes with protein synthesis, leading to cell death. Additionally, as a polymer, povidone can enhance drug solubility and stability by forming a hydrophilic matrix.

Pharmacodynamics

Povidone has a broad spectrum of antimicrobial activity against bacteria, viruses, and fungi. Its antiseptic properties are primarily due to the release of iodine, which is effective in reducing microbial load and preventing infection. The polymer's ability to bind to various substances allows it to be utilized in formulations that require improved stability and solubility.

Pharmacokinetics

Povidone is not absorbed systemically when applied topically, as it remains localized at the site of application. Its pharmacokinetics are largely dependent on the formulation and route of administration, with the polymer being metabolized by hydrolysis and excreted in urine as low-molecular-weight compounds. The release and activity of iodine are influenced by the concentration of povidone and the presence of organic matter.

Adverse effects

• Local irritation
• Allergic reactions
• Skin rashes
• Hypersensitivity reactions

Precautions

• Use with caution in patients with known allergies to iodine or povidone-iodine
• Avoid use in deep puncture wounds or serious burns

Pregnancy

Povidone is generally considered safe for use during pregnancy, but it is advisable to consult a healthcare professional before use.

Breast-feeding

Mechanism of action

Surfadone acts by disrupting the bacterial cell membrane integrity, leading to cell lysis and death. It also interferes with bacterial metabolic processes, inhibiting the synthesis of essential proteins and nucleic acids. This dual action makes it effective against diverse microbial species.

Pharmacodynamics

The pharmacodynamic properties of surfadone include its ability to exhibit bactericidal effects at appropriate concentrations. It displays rapid action against susceptible organisms, with a minimum inhibitory concentration (MIC) that varies based on the specific microbial strain. Its effectiveness is also influenced by factors such as pH and the presence of organic matter.

Pharmacokinetics

Surfadone is generally well-absorbed when administered topically, with systemic absorption being minimal. Its distribution throughout the body is variable, depending on the route of administration. The drug undergoes hepatic metabolism and is excreted primarily via the kidneys. The half-life of surfadone is influenced by factors such as age, renal function, and the specific formulation used.

Pregnancy

Limited data is available on the safety of surfadone during pregnancy. It is advised to use caution and consult a healthcare provider.

Breast-feeding

It is unknown whether surfadone is excreted in human milk. Caution is advised when administering to breastfeeding mothers.

Storage

Store at room temperature, away from moisture and heat. Keep out of reach of children.

Mechanism of action

Molecular iodine is known to inhibit the induction and promotion of N-methyl-n-nitrosourea-induced mammary carcinogenesis, to regress 7,12-dimethylbenz(a)anthracene-induced breast tumors in rats.It has also been shown to have beneficial effects in fibrocystic human breast disease. An acute iodide excess (above the preexisting dietary intake) transiently decreases the production of thyroid hormones in the thyroid gland; this is referred to as the acute Wolff-Chaikoff effect. In normal people, this is followed by a return to normal levels of hormone synthesis, referred to as escape from the acute Wolff-Chaikoff effect, without a significant change in circulating hormone levels. Escape is thought to be the result of down regulation of the sodium-iodide symport (NIS), the iodide transporter in the thyroid gland, resulting in a decrease in the intrathyroidal iodine and the resumption of normal hormone synthesis. An acute or chronic excess of iodide can also decrease circulating T4 and T3 levels and induce a hypothyroid state in some people who have underlying thyroid disorders. These effects are the result of a failure to escape from the acute Wolff-Chaikoff effect. Most people who experience iodine-induced hypothyroidism recover when the excess iodine intake is discontinued.
