Crystapen contains benzylpenicillin, a narrow spectrum antibiotic which has a bacteriostatic effect at low concentrations (minimum of 0.03 units per ml) and is bactericidal at higher concentrations to organisms in the growth phase (0.5 units per ml). Penicillin is active primarily against gram-positive bacteria. Its action is unaffected by blood or pus and it does not affect leucocyte metabolism.
