Protamine Sulfate Mechanism of Action (API Function)
Protamine sulfate acts by electrostatic binding to heparin:
• Heparin is a strongly anionic glycosaminoglycan used as an anticoagulant.
• Protamine is a strongly cationic protein; when combined with heparin, they form a stable, inactive salt complex with no anticoagulant activity. Scrianen API+1
This neutralization is rapid (typically within ~5 minutes after IV administration).
Additionally:
• Unbound protamine itself can have a weak anticoagulant effect at high doses.
• Some interactions with clotting factors (e.g., factor Xa/antithrombin complexes) have been observed in experimental contexts

Chloroquinaldol Promestriene Vaginal Tablets is a drug combination that includes chloroquinaldol and an artificially synthesized estrogen - Promestriene. Their functions mainly have two aspects:
1. Antibacterial effect: Chloroquinaldol is a broad-spectrum antibacterial drug that has bactericidal or inhibitory effects on various bacteria, fungi, and parasites. Therefore, chloroquinaldol can be used to treat inflammatory diseases such as vaginal infections and cervicitis.
2. Hormone replacement therapy: Promestriene is a synthetic estrogen that can be used to replace natural estrogen that is lacking in the body. When women enter menopause or are in the later stages of menopause, due to ovarian dysfunction, hormone levels may decrease, leading to a series of uncomfortable symptoms such as vaginal dryness, frequent urination, irregular menstruation, etc. The use of estradiol can alleviate these symptoms and improve the health of the vaginal mucosa.

we manufacture promestriene API and chloroquinaldol API

Protamine sulfate is a highly basic, arginine-rich peptide/protein used as an active pharmaceutical ingredient (API), primarily to neutralize the anticoagulant effects of heparin. The API consists of a mixture of basic peptides derived from fish s***m — traditionally salmon milt — that form a sulfate salt suitable for pharmaceutical use.
CAS Number: 9009-65-8
Chemical Type: Polypeptide/biologic API
Physical Form: White to off-white powder (sparingly soluble in water; insoluble in ethanol/ether)
Composition: Rich in arginine residues, giving it a strong positive charge at physiological pH

L-5-Methyltetrahydrofolate calcium (L-methylfolate calcium)

⭐ 1. Chemical Structure
Chemical name:
Calcium (2S)-2-[[4-[[(6S)-2-amino-5,6,7,8-tetrahydro-4-hydroxy-6-methylpteridin-yl]methyl]amino]benzoyl]amino]pentanedioate
Molecular formula:
C₂₀H₂₁CaN₇O₆
Common abbreviation: L-5-MTHF-Ca or L-Methylfolate Ca
Structure components:
Pteridine ring
L-methyl group at carbon 5 (defining the biologically active form)
Glutamate tail
Calcium counter-ion to stabilize the molecule
Notes:
The calcium salt form is more stable and widely used in supplements.
Another form you may see is L-5-MTHF glucosamine salt —more soluble, but similar function.

L-5-Methyltetrahydrofolate calciumis is the active metabolite of folic acid and folate from food, directly usable by the body.Unlike folic acid, it does not need conversion by MTHFR (methylenetetrahydrofolate reductase) enzyme, which is often genetically impaired in some people.
Advantages Over Folic Acid
• Higher bioavailability
• Works even in individuals with MTHFR polymorphisms (C677T, A1298C)
• Crosses the blood–brain barrier more efficiently

Polydeoxyribonucleotide (PDRN)
Medical & Therapeutic Uses
• Tissue regeneration: Stimulates cell growth, angiogenesis (new blood vessel formation), and wound healing.
• Anti-inflammatory effect: Modulates cytokine release and reduces inflammation.
• Skin rejuvenation & aesthetics: Used in dermatology and cosmetic medicine to improve skin elasticity, hydration, and anti-aging effects.
• Orthopedics: Assists in tendon and ligament healing, and reduces pain in musculoskeletal injuries.
• Diabetic ulcers & chronic wounds: Enhances healing and tissue repair.
• Anti-hair loss：
• Reproductive Health and Male Infertility: Protamine is rich in arginine, which stimulates the pituitary gland to release gonadotropins, enhances liver function, and treats male infertility caused by insufficient semen secretion and s***m deficiency. Furthermore, the trace element zinc in fish s***m DNA can increase plasma testosterone levels and s***m count, synergizing with arginine and DNA to improve semen quality.

Acetazolamide Pharmacological Applications
Glaucoma: Used to reduce intraocular pressure in open-angle and secondary glaucoma, and as an adjunct in acute angle-closure glaucoma before surgery.
Edema: Manages edema due to congestive heart failure, though it is less potent than loop diuretics and often used in combination.
Altitude Sickness: Prophylaxis and treatment of acute mountain sickness (AMS) by inducing metabolic acidosis and respiratory alkalosis.
Epilepsy: Adjunctive therapy in certain types of seizures, particularly absence seizures.
Other Uses: Management of idiopathic intracranial hypertension, periodic paralysis, and as a urine alkalinizer.

Trihexyphenidyl hydrochloride is a synthetic anticholinergic agent primarily used in the treatment of Parkinson's disease and drug-induced extrapyramidal symptoms. It works by reducing the effects of acetylcholine, a neurotransmitter that is imbalanced in these conditions, leading to the alleviation of muscle stiffness, tremors, and spasms. Below is a detailed description of its properties, uses, and other attributes
