Pharmacological Effect of API Powder Salicylic Acid

Methyl salicylate has a pleasant holly scent and is used to formulate perfumes and soap fragrances. When applied to the skin, methyl salicylate penetrates into the muscles and releases salicylic acid to relieve local pain, thus it can also be used as a topical remedy for pain, contusions and sprains. Isoamyl salicylate has an orchid-like aroma, while benzyl salicylate has a faint fragrance of vanillin, both of which can be used to make perfumes or soap fragrances. Phenyl salicylate, commonly known as salo, is hydrolysed in the intestine to phenol and salicylic acid and is an effective enteric preservative. Another drug related to salicylic acid is para-aminosalicylic acid (PAS, see 'para-aminosalicylic acid'), the sodium and calcium salts of which are used as an anti-tuberculosis agent for acute exudative and mucosal tuberculosis, a weak antibacterial agent with only 2% of the action of streptomycin, often used in combination with streptomycin and isoniazid to enhance its efficacy. Acetylated to produce aspirin.
