Hydrochloride is easily hygroscopic, with a melting point of 177.5°C (decomposition). Allergy testing is required before use.
Should be sealed and stored dry at 4°C.
Produced by degradation or synthesis of penicillin. It is derived from the hydrolysis of penicillin G potassium salt.
It is a detoxifying agent for heavy metals such as copper, mercury and copper. It is also used to treat autoimmune diseases such as hepatolenticular degeneration (Wilson’s disease) and rheumatoid arthritis caused by copper deposition in tissues. It is contraindicated in patients with penicillin allergy, hematopoietic dysfunction, and renal insufficiency.
