Abstract
Intoroduction:Prodrug approach deals with chemical biotransformation or enzymatic conversion or involves inactive or less active bio-reversible derivatives of active drug molecules. They have to pass through enzymatic or chemical biotransformation before eliciting their pharmacological action.Methods & Materials:The two different pharmacophores combine to give synergistic activity or may help in targeting the active drug to its target. Prodrug super seeds the problems of prodrug designing, for example solubility enhancement, bioavailability enhancement, chemical stability improvement, presystemic metabolism, site specific delivery, toxicity masking, improving patient acceptance, or eradicating undesirable adverse effects.Results:As an outcome the search for a prodrug or mutual prodrug with reduced toxicity has continued during recent years. This present review emphasizes the common help to revamp physiochemical, pharmaceutical and therapeutic effectiveness of drugs.Conclusion:This gives the researcher a common platform where they can find prodrugs of commonly used NSAIDs to overcome the gastrointestinal toxicity (irritation, ulcergenocity and bleeding).
Highlights
The term prodrug was first coined by Albert [1]
C) Site specific prodrug Such prodrug is used for targeting the active drug at specific site, e.g. sulfasalazine (Fig. 5) which consists of 5aminosalicylic acid and sulfapyridine
The prodrug is synthesized with morpholinoalkyl ester prodrugs of diclofenac for oral delivery (Fig. 28) and evaluated for in vitro and in vivo analysis for their potential use as prodrugs [21]
Summary
The two different pharmacophores combine to give synergistic activity or may help in targeting the active drug to its target. Prodrug super seeds the problems of prodrug designing, for example solubility enhancement, bioavailability enhancement, chemical stability improvement, presystemic metabolism, site specific delivery, toxicity masking, improving patient acceptance, or eradicating undesirable adverse effects
