What is Minoxidil Sulfate API used for?

Minoxidil Sulfate API is the active sulfate metabolite of minoxidil (U-58838) that is required to exert the vasodilatory and hair-growth effects of minoxidil. It is used as the active pharmaceutical ingredient in medications for treating androgenetic alopecia (male and female pattern hair loss) and alopecia areata, and as a vasodilator in the management of hypertension.

What is the difference between Minoxidil and Minoxidil Sulfate?

Minoxidil is a prodrug that must be converted by sulfotransferase enzymes in the skin to its active metabolite, Minoxidil Sulfate. Minoxidil Sulfate is the active form that directly opens KATP channels and stimulates hair follicles. It possesses greater aqueous solubility than minoxidil and is a more potent vasodilator.

What are the brand names for Minoxidil Sulfate?

Minoxidil Sulfate is the generic name for the active metabolite. It is also known as Minoxidil Sulfate, U-58838, and MXS. The parent drug minoxidil is marketed under brand names including Rogaine®, Loniten®, and numerous generic formulations.

What purity level do you guarantee for Minoxidil Sulfate API?

We guarantee ≥98.0% purity (HPLC-verified), with ≥99.0% purity available for high-end formulations. Every batch is tested for identity, purity, and quality parameters in accordance with pharmaceutical industry standards.

What documentation do you provide with each order?

Every shipment includes a Certificate of Analysis (CoA), Method of Analysis (MOA), Material Safety Data Sheet (MSDS), and stability data. For regulatory submissions, we provide DMF access letters and complete manufacturing process documentation.

What is your minimum order quantity (MOQ)?

For pharmaceutical manufacturers, our MOQ is 1 kg, with volume discounts available for larger commercial orders. For R&D, analytical research, and compounding pharmacy applications, we offer smaller quantities starting from 5 mg, 100 mg, or 1 g.

Is your Minoxidil Sulfate API GMP-certified?

Yes. Our API is produced in facilities that adhere to strict current Good Manufacturing Practices (cGMP) for pharmaceutical APIs and fully comply with ICH Q7 guidelines. We maintain DMF filings with regulatory authorities.

What is the mechanism of action of Minoxidil Sulfate?

Minoxidil Sulfate is a potent activator of the ATP-sensitive K⁺ (KATP) channel. It opens KATP channels in vascular smooth muscle and dermal papilla cells, causing hyperpolarization and vasodilation. This increases blood flow to hair follicles and upregulates growth factors, including VEGF. It also promotes the survival of dermal papillary cells by activating ERK and Akt pathways.

What is the solubility and storage profile of Minoxidil Sulfate API?

Minoxidil Sulfate is a white crystalline solid that is soluble in DMSO at 55–100 mg/mL. It should be stored as a powder at -20°C (3 years) or 4°C (2 years). In solvent, it should be stored at -80°C for 6 months or -20°C for 1 month, protected from light and moisture.

What is the current market size for Minoxidil Sulfate API?

The global Minoxidil API market was valued at USD 1.2 billion in 2024 and is projected to reach USD 2.5 billion by 2034 at a CAGR of 7.5%. The Minoxidil Sulfate market was valued at USD 0.5 billion in 2024 and is projected to reach USD 1.2 billion by 2034 at a CAGR of 8.5%. Alternative projections indicate a valuation of USD 484 million in 2025, reaching USD 997 million by 2035 at a CAGR of 7.5%.

Is Minoxidil Sulfate FDA-approved?

Minoxidil is the only FDA-approved topical active pharmaceutical ingredient (API) for androgenetic alopecia in both men and women. While Minoxidil Sulfate is the active metabolite responsible for efficacy, the regulatory framework for minoxidil-containing products is well-established with multiple ANDA approvals.

What are the common side effects of Minoxidil Sulfate?

The most common side effects are itching and skin irritation at the treated area of the scalp. Other effects may include dryness, scaling, local irritation, and contact dermatitis. Pruritus (severe itching of the skin) and adverse drug reactions have been reported. In rare cases, systemic effects such as dizziness or lightheadedness may occur, especially if too much is applied or if it is accidentally ingested.

What are the contraindications for Minoxidil Sulfate?

Minoxidil Sulfate should not be used by individuals with known hypersensitivity to minoxidil or any excipients. Pregnant and nursing women should consult their healthcare provider before use. It is not recommended for individuals under 18 years of age without medical supervision.

What drug interactions should be considered?

Patients should inform their healthcare provider about all medications they are using, particularly other topical scalp treatments. Compounded formulations may include finasteride, tretinoin, and melatonin; a qualified healthcare professional should evaluate potential interactions.

Can you supply Minoxidil Sulfate API for compounding pharmacy applications?

Yes. We supply Minoxidil Sulfate API in quantities suitable for compounding pharmacies. Our API can be used to formulate patient-specific doses and combination therapies with ingredients such as finasteride, tretinoin, and melatonin to enhance effectiveness.

What is your typical lead time?
