AB A rat skeletal muscle cell line (L6) was evaluated for its utility in assessing cellular damage caused by parenteral administration of eight commercially available pharmaceuticals. The physical forms of the eight pharmaceuticals were diverse, including aqueous and non-aqueous suspensions and solutions. The L6 cells were exposed to therapeutic as well as diluted concentrations of methocarbamol, lorazepam, dimercaprol, phytonadione, menadiol sodium phosphate, penicillin G procaine, penicillin G benzathine, and iron dextran complex. Irritation assessment was based on the depletion of creatine phosphokinase (CK)from treated cultures versus untreated controls. The results obtained correlate well with reports of irritation and side effects noted in clinical use, and demonstrate the versatility of the model for testing suspensions and nonaqueous parenteral solutions. The L6 model is a useful tool to assist in determining the relative local irritancy of parenteral products.
