Abstract
Introduction: In an attempt to circumvent the lipophilicity burden for the oral administration of new potent synthetic melatoninergic fluorine-substituted methoxyphenylalkyl amides, we conducted in vitro modified release studies using carefully selected matrix tablets’ biopolymeric materials in different ratios.
Method: In particular, we sought to attain release profiles of these analogues similar to that of the parent compound, the chronobiotic hormone Melatonin (MLT), and also of the commercially available drug, Circadin®.
Result: It was found that some of these systems, albeit being more lipophilic than MLT, mimic the in vitro release patterns of melatonin and Circadin®.
Conclusion: Moreover, a number of these derivatives were proven suitable for dealing with sleep onset problems, whilst others for dealing with combined sleep onset/sleep maintenance dysfunctions
Keywords: melatonin, synthetic melatoninergic analogues, lipophilicity, matrix tablets, in vitro dissolution studies
