Its rapid onset of action and high potency make it valuable in emergency and systemic therapy.
Bromelain
Bromelain is a natural mixture of proteolytic enzymes derived primarily from the stem and fruit of the pineapple plant (Ananas comosus). It appears as a pale yellow to off-white powder with a characteristic mild odor and is water-soluble. Bromelain exhibits protease activity, breaking down proteins into peptides and amino acids, making it valuable in medical, food, and industrial applications. It is widely used as an anti-inflammatory agent, digestive aid, meat tenderizer, and in cosmetic formulations due to its enzymatic and therapeutic properties.
Colistin Sulphate BP
Colistin Sulphate BP is an antibiotic belonging to the polymyxin class, derived from the bacterium Paenibacillus polymyxa. It is a white to pale yellow powder, soluble in water, and used primarily for its potent bactericidal activity against Gram-negative bacteria, including multidrug-resistant strains. Colistin Sulphate BP is used in both human and veterinary medicine, often as a last-resort treatment for serious infections caused by multidrug-resistant Pseudomonas, Acinetobacter, and Klebsiella species. Due to its efficacy and narrow therapeutic index, its use is carefully monitored. The “BP” denotes compliance with the British Pharmacopoeia standards.
Diclofenac Sodium BP
Diclofenac Sodium is a nonsteroidal anti-inflammatory drug (NSAID) widely used for its potent analgesic, anti-inflammatory, and antipyretic properties. It is the sodium salt form of diclofenac, providing enhanced solubility and rapid absorption.

Folic Acid
Folic Acid, also known as Vitamin B9 or pteroylmonoglutamic acid, is a water-soluble vitamin essential for numerous physiological processes including DNA synthesis, repair, and methylation, as well as amino acid metabolism. It appears as a yellow to orange-yellow crystalline powder, odorless or with a faint characteristic odor. Folic Acid is vital for cell division and growth, making it critical during pregnancy and periods of rapid growth. It is widely used in the pharmaceutical, nutraceutical, food fortification, and cosmetic industries due to its role in preventing folate deficiency anemia, neural tube defects in newborns, and supporting overall cellular health.
Fructose
Fructose, also known as fruit sugar, is a naturally occurring monosaccharide found in many plants, fruits, honey, and root vegetables. It is a simple sugar with a sweet taste and is one of the three dietary monosaccharides, alongside glucose and galactose. Fructose appears as a white crystalline powder, highly soluble in water, and is commonly used as a sweetener in food and beverage industries due to its high relative sweetness. It plays important roles in metabolism and is used extensively in the production of high-fructose corn syrup (HFCS) and other sweetening agents.
Hydrocortisone Acetate
Hydrocortisone Acetate is a synthetic corticosteroid ester derived from hydrocortisone (cortisol). It is a white to off-white crystalline powder, practically insoluble in water but soluble in alcohol and acetone. This compound exhibits potent anti-inflammatory, immunosuppressive, and anti-allergic properties, making it widely used in pharmaceutical and dermatological formulations. Hydrocortisone Acetate acts by modulating gene expression to reduce the production of inflammatory mediators, thereby alleviating symptoms in various inflammatory and autoimmune conditions.
Manganous Dihydrogen Phosphate
Manganous Dihydrogen Phosphate is an inorganic manganese compound with the formula Mn(H₂PO₄)₂. It is typically encountered as a hydrated crystalline solid that is soluble in water. This compound serves as a valuable source of manganese and phosphorus in agricultural and industrial applications. It is primarily used as a micronutrient fertilizer component, an additive in animal feed, and a reagent in chemical syntheses. Its high solubility makes it effective for foliar sprays and soil applications to correct manganese deficiencies in crops.
