Calmasol 440 Solution for Infusion

Indications

• Vulvovaginal candidiasis
• Fungal infections
• Antiseptic for minor cuts and abrasions
• Ocular antiseptic
• Insecticide in pest control

Dosage

Adults: Refer to specific guidelines for formulations. Commonly used as a 2-3% solution

Mechanism of action

Boric acid exerts its antifungal effects by disrupting the cell membrane integrity of fungi. It interferes with the synthesis of essential cellular components, leading to cell lysis and death. The acid also has mild antibacterial properties, which can help in reducing bacterial load in infected areas. The exact molecular pathways involved in these actions are not fully elucidated, but it is known to alter the pH of the environment, making it less conducive for fungal growth.

Pharmacodynamics

Boric acid demonstrates a low toxicity profile in humans when used appropriately. Its antifungal activity is primarily effective against Candida species, and it can be used as a second-line treatment for vulvovaginal candidiasis, particularly in cases of recurrent infections. The effectiveness of boric acid is also attributed to its ability to maintain an acidic environment, which is unfavorable for the growth of many pathogens. Its antiseptic properties help in reducing inflammation and promoting healing in infected tissues.

Pharmacokinetics

Boric acid is poorly absorbed through the gastrointestinal tract but can be absorbed through the skin and mucous membranes. Once absorbed, it is distributed throughout the body, with a tendency to accumulate in various tissues, including the liver and kidneys. The elimination half-life of boric acid is variable, depending on dosage and route of administration. It is primarily excreted unchanged in the urine. Due to its potential for toxicity with high systemic exposure, it is important to adhere to recommended dosages.

Mechanism of action

Hexa functions primarily as a source of energy through beta-oxidation, where it is broken down into acetyl-CoA units that enter the citric acid cycle. This process ultimately leads to the production of ATP, which is essential for cellular energy.

Pharmacodynamics

Hexa contributes to the regulation of metabolic pathways involving fatty acids. It influences energy homeostasis and can impact lipid profiles in the body. The presence of medium-chain fatty acids like hexa can promote ketogenesis, especially in carbohydrate-restricted diets, providing an alternative energy source.

Pharmacokinetics

Hexa is absorbed through the gastrointestinal tract and is rapidly metabolized in the liver. It has a relatively short half-life, and its metabolites are efficiently utilized or excreted by the body. The pharmacokinetic profile may be affected by dietary factors and individual metabolic rates.

Pregnancy

Hexa should only be used in pregnancy if the benefits outweigh the risks. Consult with a healthcare professional.

Breast-feeding

It is unknown if hexa is excreted in human milk. Caution is advised when administering to nursing mothers.

Storage

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