title: Abuse and pulmonary complications of injecting pentazocine and tripelennamine tablets.
abstract: A current practice among drug abusers in certain Midwestern and Eastern cities is the intravenous injection of aqueous mixtures prepared from tablets of pentazocine and tripelennamine. Patients present with acute hypoxic episodes and symptoms suggesting physical dependence to pentazocine. Two cases are presented illustrating acute respiratory distress with hypoxia. Available evidence indicates that the respiratory syndrome is produced by talc from the injected tablets. Respiratory support and short-term oxygen therapy have been effective in managing this syndrome. Approaches to the treatment of pentazocine dependence and the role of the antihistamine in potentiating the narcotic activity are also discussed. Physicians, drug abuse counselors, and others should be aware of the abuse potential and pulmonary damage which can result from the intravenous use of this drug combination.
