The pharmaceutical research sector is highly interested in oral gastro-retentive dose formulations. The significance of gastro-retentive drug delivery systems (GRDDS) has grown as these systems enhance patient compliance and improve the therapeutic indices of medications. Various technical advancements in the design and production of gastro-retentive dosage forms can overcome physiological limitations, such as short gastric retention time and fluctuations in stomach emptying. Medications with shorter half-lives, instability or poor solubility at alkaline pH, or inadequate absorption in the lower gastrointestinal tract can greatly benefit from GRDDS. To achieve the desired retention period and release pattern, these systems can be developed using a range of innovative methods, including magnetic, bioadhesive, expandable, and floating systems. The use of GRDDS for oral drug administration has significantly increased in recent years, with innovative design strategies—such as the widely used floating drug delivery system—playing a major role. GRDDS offer several advantages, including the ability to provide drugs with a narrow absorption window, improved pharmacological effects, reduced dosing frequency, enhanced bioavailability, and prolonged drug residence in the stomach for local effects such as the treatment of peptic ulcer disease. This study provides a brief introduction to gastro-retentive drug delivery, covering its necessity, advantages, disadvantages, influencing factors, approaches, and applications.

The use of aromatherapy for the reduction of anxiety levels during dental treatment procedures has been well established in the literature; however, there is limited evidence regarding its efficacy. The present meta-analysis is an attempt to assess the association between the use of aromatherapy and anxiety levels among dental patients.A comprehensive search was conducted across Medline, Scopus, Web of Science, EBSCO host, Cochrane databases, and Google Scholar for studies evaluating aromatherapy and anxiety level among dental patients. PRISMA guidelines were followed for the meta-analysis. Randomized and cluster-randomized trials comparing aromatherapy with controls were included. The random-effects model was used to assess the mean differences in anxiety levels of patients visiting dental OPD. The significance value was set at P < 0.05. Six studies were identified that met the requirements for inclusion. Aromatherapy was significantly associated with reduction in patient anxiety levels during dental treatment (pooled mean difference: -3.36 [95% CI, -3.77 – -2.95, P = 0.00001). Low heterogeneity was noted between studies (I2 = 1%, P = 0.41) analyzed in the meta-analysis. High certainty of the evidence was obtained from the association between the use of aromatherapy and dental anxiety. This meta-analysis suggests that aromatherapy is effective in reducing dental anxiety. When used judiciously, the results of this work should encourage the use of aromatherapy to reduce patient anxiety levels during dental procedures
