Glaucoma is an ocular condition characterized by elevated intraocular pressure (IOP). Conventional treatments of glaucoma face poor corneal permeability and bioavailability. To address these issues, a nanoemulsion in situ gel of Timolol maleate was developed in this study by adding the polymer Carbopol 934p. Using Carbopol 934p, a novel ophthalmic pH-induced nanoemulsion in situ gel was formulated. The formulation was liquid at pH 4 and quickly gelled when the pH was raised to 7.4 (Lacrimal pH). The pH-triggered in situ gelling mechanism demonstrated continuous drug release over a 24 h cycle. A total of nine trial formulations were prepared (NEI₁–NEI₉) and subjected to various physicochemical and in vitro evaluations. According to the in vitro release kinetics, the drug release of Timolol maleate nanoemulsion in situ gel NEI₅ followed zero-order kinetics, with a release exponent value of 0.902, indicating that the mechanism of release was non-Fickian diffusion regulated. In vivo results showed that Timolol maleate nanoemulsion in situ gel NEI₅ provided a better-sustained release of the drug, compared with the Timolet OD eye drops. The formulation is stable in storage, with no distinguishable change in appearance, physical properties, quality, and percentage drug release. NEI₅ also reduces drug administration frequency, which improves patient compliance. Timolol maleate nanoemulsion in situ gel NEI₅ achieved the goal of controlled drug delivery with extended-release and cost-effectiveness, lowering the dosage and frequency of drug administration, and thus may improve patient compliance. In conclusion, the stable nanoemulsion in situ gel of Timolol maleate NEI₅ decreases intraocular pressure (IOP) over a prolonged period.

Quetiapine Fumarate is potent, and the daily therapeutic dose can be delivered easily across the skin with the help of permeation enhancers. Quetiapine Fumarate-loaded transdermal patches were prepared by solvent evaporation technique. Various formulation parameters, excipients, and their combinations were optimized to get thin, translucent, smooth, stable, and high permeable character patches. A total number of 10 formulations were prepared. All formulations were subjected to various physicochemical evaluations. Three different formulations were prepared and F1, F2, and F3. Various physicochemical studies were carried out and found no significant difference between the three batches. The in vitro release study showed 74.29%, 82.73%, and 77.27%, respectively, up to 24 h. From the results, F2 has been selected as an optimized formulation and evaluated for skin irritation test. The results revealed that there is no irritation produced. The stability study results showed that there is no significant change from its initial nature till the period of three months in both temperatures. Quetiapine Fumarate Transdermal Patch F2 has achieved the goal of extended-release, cost-effectiveness, lowering the dose and frequency of drug administration, and thus may improve patient compliance.

The present study highlights the Bio activities and Pharmacology of Piper nigrum L. (Black Pepper). Piper nigrum L is commonly known as Kali Mirch, Pippali, Milagu Peppercorn, White pepper, Green pepper, Black pepper, and Madagascar pepper longum plant is a deciduous slender aromatic climber. The major source of bioactive constituents in black pepper is present in the fruits. It contains major pungent alkaloid piperine (1-peperoyl piperidine) which is known to possess pharmacological actions. Antimicrobial activity of black pepper evaluated the antibacterial potential of aqueous decoction of Piper nigrum L. (black pepper), against different bacterial isolates from oral cavity of individual volunteers.

Sodium is a key element for all living things, mainly animals, some plant species, and humans. In animals, sodium ions are necessary for the regulation of blood and body fluids, the transmission of nerve impulses, heart activity, and certain metabolic functions. Sodium is the chief cation in the extracellular compartment of an animal body. Sodium plays a vital role not only in the human body but also in various food types. Salt, also known as sodium chloride, is about 40% sodium and 60% chloride. It flavors food and is used as a binder and stabilizer. The sodium content in different brands of edible salts can be analyzed using flame photometry. Flame photometry, also called flame atomic emission spectrometry, is a branch of atomic spectroscopy in which the species examined in the spectrometer are in the form of atoms. The samples used for analysis are junk foods, which have become a common trend among all generations. A total of 13 brands were analyzed for iodine content. From that, two commonly used brands were selected and analyzed for estimating the sodium and potassium contents in them by flame photometry. The analysis helps in creating awareness among all generations to reduce the sodium intake in order to prevent problems like hypertension, hyponatremia, hypernatremia, and associated medical complications in the future.

The accessibility and low cost of herbal medicine are contributing to its growing popularity. The majority of pregnant mothers choose to use herbal remedies to treat pregnancy symptoms like nausea, headaches, and so forth. This study aims to determine how common it is for women to use herbal remedies while pregnant in Bahla, Sultanate of Oman. The study was a cohort study involving between 80 and 100 pregnant women. Along with the consent form, a questionnaire was used to gather the quantitative data (both English and Arabic). Face-to-face interviews were employed in the collection of qualitative data. It was reported that 17% of pregnant women have used herbal medicine. Forty-seven percent of them were taking herbal medicine at the time of delivery, according to the study. 43.8% of people believe that the primary cause is the inadequacy of modern medicine. As mentioned by 52.9% of pregnant women, the primary goal of using herbal medicine is to speed up labor. Additionally, 23.5% of them said that using herbal medicine is to start labor. The results of this study showed that women in Bahla frequently use herbal remedies during pregnancy. The most widely used herbal remedies were Verbenaceae, Fenugreek, Castor oil, Brown sugar, and Saffron. It is recommended that social media should be used to raise awareness of the pregnancy-related effects of herbal medicine. Additionally, those involved in antenatal care, in particular, should be aware of the evidence about the potential benefits or risks of herbal medicinal agents.
