A review on analgesic and anti-inflammatory activities of various piperazinyl containing pyridazine derivatives

Most currently used nonsteroidal anti-inflammatory drugs (NSAIDs) have restrictions for therapeutic use since they cause gastrointestinal and renal side effects that are undividable from their pharmacological activities. In this review various piperazinyl containing pyridazine derivatives have been studied for their analgesic and anti-inflammatory activities and their side effects. Therefore, the synthesis of new compounds devoid of such side effects has become an important goal for medicinal chemists.
