Penicillin G is a natural penicillin and is obtained from cultures Penicillium chrysogenum and is available in several different salt forms. Penicillin G potassium (also known as benzylpenicillin potassium, aqueous or crystalline penicillin) occurs as colorless or white crystals, or white crystalline powder. It is very soluble in water and sparingly sol­uble in alcohol. Potency of penicillin G potassium is usually expressed in terms of Units. One mg of penicillin G potassium is equivalent to 1440-1680 USP Units (1355-1595 USP Units for the powder for injection). After reconstitution, penicillin G potassium powder for injection has a pH of 6-8.5, and contains 1.7 mEq of potassium per 1 million Units.
