It is now acknowledged that Attention-deficit Disorder with Hyperactivity (ADHD) is not limited to children or adolescents. Regardless of culture, up to 4% of the adults in the general population might be diagnosed with ADHD, a disorder often accompanied by comorbid psychiatric disorders. Among those is Substance Abuse including cigarette smoking. Indeed, ADHD patients tend to start with drugs earlier than normal controls. Pharmacological treatments of ADHD chiefly encompass amphetamine salts, methylphenidate and atomoxetine with a good tolerance and effectiveness. These treatments are even better tolerated now that long-acting, extended-release formulations and transdermal delivery systems become available. But it is likely that some patients will still not respond, especially when comorbid disorders are associated. Other agents are being tested as future pharmacotherapies of ADHD. Here we propose a review of the literature concerned with the relationships between cigarette smoking and ADHD in adolescent and adult patients, and an overview of the future pharmacotherapies of ADHD related with nicotine receptor agonists.

The present study was aimed to develop an extended release tablet of metoprolol Succinate for the treatment of hypertension.  Four extended release formulations F1-F4 were developed using varying proportions of hydroxylpropyl-methylcellulose K100M, sodium carboxy methyl cellulose and Eudragit L30 D55 by wet granulation. Five extended release formulations F5-F9 containing HPMC K100M and HPMC 5 cps in varying concentration were developed by direct compression. The physicochemical and in vitro release characteristics of all the formulations were investigated and compared. Two formulations, F7 and F8 have shown not more 25% drug release  in 1st h, 20%-40% drug release at 4th hour, 40%-60% drug release at 8th hour and not less than 80% at 20th hour and the release pattern conform with USP specification for 24 hours extended release formulation. It can be conclusively stated that optimum concentration of HPMC K100M (58%-65%) by direct compression method can yield an extended release of metoprolol succinate for 24 hours.

Carcinosarcoma, leiomyosarcoma, melanoma and carcinoid as primary tumors in the ovary are extremely rare. In this paper, the authors reviewed the literature from 2010 to 2021, based on specific criteria, to analyze the treatment of these rare ovarian neoplasms. We also aimed to verify whether modern therapies have been found in recent years. For this article, 80 papers were finally selected. The vast majority of the articles were clinical case reports. Despite single mentions of new potential pharmacological treatments, surgery (radical or fertility-sparing) is definitely the mainstay of treatment. There are currently no treatment guidelines for these tumors. A review of the literature has revealed the use of various adjuvant treatments. We, therefore, believe that a more detailed understanding of the biology of these tumors is necessary in order to find new target points for treatment. We would like to emphasize the importance of creating an international database of rare ovarian tumors which would make it possible to gather data from various oncological centers and enable further research into these neoplasms.
