Abstract

The invention discloses a sulfanilamide medicament composition for a wound surface. The medicament composition contains sulfadiazine zinc, sulfadiazine silver and laurocapram, and can further contain preservative and medicinal calcium salt. The medicament composition is prepared into clinically acceptable formulations such as gel, mucilage, film coating agent and the like according to a conventional process by adding medicinal auxiliary materials. The medicament composition has strong antibacterial and bacteriostatic effects, obviously shortens the healing time of the wound surface, has good pain easing effect, is safe, effective and convenient to use; and the composition has stable anti-freezing property.

Description

technical field [0001] The invention belongs to the field of pharmaceutical compositions, and in particular relates to a sulfonamide pharmaceutical composition, a preparation method thereof, and a pharmaceutical preparation prepared therefrom. Background technique [0002] Sulfadiazine silver (SD-Ag), the English name is Sulfadiazine Silver, the chemical name is N-2-pyrimidinyl-4-aminobenzenesulfonamide silver salt; the molecular formula is C 10 h 9 AgN 4 o 2 S, molecular weight: 357.14, chemical structural formula as follows: [0003] [0004] Silver sulfadiazine is white or off-white crystalline powder, which is easy to deteriorate when exposed to light or heat, and is insoluble in water, ethanol, chloroform or ether. [0005] Silver sulfadiazine has a strong inhibitory effect on the dominant burn bacteria Pseudomonas aeruginosa, and silver salt has astringent effect, which can make the burn wound dry, scab and heal early. [0006] Sulfadiazine zinc (SD-Zn), Englis...
