Sustained release system is types of modified drug delivery system that can be used as an alternative to conventional system. Among different dosage forms, matrix tablets are widely accepted for oral sustained release Metformin hydrochloride has relatively short plasma half-life, low absolute bioavailability. The need for the administration two to three times a day when larger doses are required can decrease patient compliance. Sustained release formulation that would maintain plasma level for 8-12 h might be sufficient for daily dosing of metformin. Sustained release products are needed for metformin to prolong its duration of action and to improve patient compliances. They are capable of reducing the dose intake, minimize the blood level oscillation dose related adverse effect and cost thus improves the patient compliance in the therapeutic management of diabetes. The Metformin hydrochloride matrix Sustained release tablets were prepared using different hydrophilic polymers in various proportions as release retarding agent to prolong the drug release and to improve the patience compliance. The tablets were evaluated for various tests like hardness, friability, disintegration and in-vitro dissolution studies.

The prevailing theory is that antidepressants increase the concentration of one or more brain chemicals (neurotransmitters) that nerves in the brain use to communicate with one another.The neurotransmitters affected by antidepressants are norepinephrine, serotonin, and dopamine. In order to address the need for new MAO inhibitors with less side effects, we can aim compounds previously discovered for their potential as MAOIs. Among them, safinamide was reported to be a potent anti-MAO B agent, and milacemide, which was found to be a potent MAO inhibitor and a prodrug for glycine. The present work deals with the aim because Currentely available MAO inhibitors {Isocarboxazid (Marplan), Phenelzine (Nardil), Selegiline (Emsam), Tranylcypromine (Parnate) etc} develop side effects because they do not selectively for MAO-A and MAO-B. So, the present study is focused to develop potent selective MAO-A inhibitors, to treat depression, that may be of better pharmacological activity with less adverse effect.
