Pharmaceutical Grade Ichthammol Medical Grade Ichthammol Complies with Pharmacopoeia Standards Sample Pack 500g per Bottle Dermatological Medication

Product Name: Ichthammol

Alias: Ichthammol, Ichthammonium

Physical Properties: A thick, viscous, dark brown liquid with a characteristic odor.

Indications: This product is a phenolic antiseptic with mild irritant, anti-inflammatory, and antiseptic effects. It can reduce inflammation, swelling, and inhibit secretion. Used for boils, psoriasis, eczema, cervicitis, vaginitis, lymphadenitis, thrombophlebitis, chronic ulcers, chronic dermatitis, radiation dermatitis, otitis externa, etc.

Ichthammol forms resinous masses when exposed to acids and releases ammonia when combined with alkaline substances. Therefore, it should not be mixed with acids, alkalis, alkaloids, or iron salts. It tends to expand and carbonize when exposed to high temperatures, which should be considered during preparation.

Quality Standards and Functions of Pharmaceutical Grade Aspirin
Aspirin, also known as acetylsalicylic acid, is a widely used non-steroidal anti-inflammatory drug (NSAID) commonly employed to relieve mild to moderate pain, reduce inflammation, and lower fever. As a common medication, the quality standards of pharmaceutical grade aspirin are established by regulations such as pharmacopoeias and Good Manufacturing Practices (GMP) to ensure its safety and efficacy in drug production.
Quality Standards of Pharmaceutical Grade Aspirin
The quality standards of pharmaceutical grade aspirin are typically based on the Pharmacopoeia and international standards. Its quality requirements involve multiple aspects, including appearance, content, impurities, dissolution rate, microbial limits, etc. Below are the key points of common quality standards for pharmaceutical grade aspirin:
1. Appearance and Characteristics
- Aspirin should be a white or almost white crystalline powder with a characteristic odor. It should be free of foreign matter and obvious contamination.
2. Content Determination
- The content of aspirin is usually required to be between 99% and 101% (on a dried basis). Content determination is generally performed using high-performance liquid chromatography (HPLC) or ultraviolet spectrophotometry.
3. Moisture Content
- The moisture content of pharmaceutical grade aspirin should be less than 0.5%. Excessive moisture may lead to degradation of aspirin, affecting its stability.
4. Acidity (Calculated as Salicylic Acid)
- The acidity of aspirin should comply with regulations, typically controlled to not exceed 0.2% (calculated as salicylic acid). High acidity may indicate hydrolysis of aspirin during storage.
5. Impurities
- The content of harmful impurities in aspirin should be controlled. For example, the content of the hydrolysis product salicylic acid should not exceed 0.5%. Additionally, the presence of other potentially toxic impurities should be tested.
6. Dissolution Rate
- The dissolution rate of pharmaceutical grade aspirin is an important indicator for evaluating its absorption rate and efficiency in the body. The Pharmacopoeia specifies the dissolution requirements for aspirin, typically requiring at least 80% of the active ingredient to dissolve within a specified time.
7. Microbial Limits
- The microbial content of pharmaceutical grade aspirin should comply with Pharmacopoeia requirements. The total microbial count should generally not exceed 100 CFU/g, and pathogenic microorganisms such as E. coli, Staphylococcus aureus, and Salmonella should not be detected.
8. Heavy Metals
- The heavy metal content of pharmaceutical grade aspirin must meet relevant standards, typically requiring total heavy metals not to exceed 10 ppm (parts per million). This ensures safety and avoids potential health risks from harmful heavy metals.
9. Packaging and Storage Requirements
- Pharmaceutical grade aspirin should be stored in a dry, cool, and well-ventilated place, avoiding direct sunlight. Packaging must be moisture-proof and contamination-resistant, using tightly sealed containers to ensure the product does not deteriorate during transportation and storage due to external factors.
