Objective: The main objectives of the present investigation work included that the preparation of a suitable naproxen semi-solid dosage form by using different types of semi-solid bases (gel bases, ointment bases) for topical application for the effective treatment of muscle aches. Methods: Different types of semi-solid bases (gel bases and ointment bases) were successfully prepared by the incorporation method to know the effect of semi-solid bases on drug release from topical semi-solid formulations. In all formulations, the drug was added by the levigation method. An evaluation study of prepared formulations, includes physical appearance, spreadability, extrudability, pH was conducted according to official methods. Results: Percent drug release of all formulations was conducted by taking diffusion cells with cellophane membrane and results showed that gel-based formulations showed more drug release than ointment-based formulations. Carbopol gel base (F1) showed more drug release (98.76 %), simple ointment base formulation (F8) showed least drug release (25.11%). From the stability studies reports at various temperature and humidity conditions it is evident that all formulations are stable for one month. In all the formulations, the drug content was observed at 95.75%. Conclusion: Finally concluded that the NXN topical dosage forms can be prepared by using gel-type bases preferably than ointment bases to release more drug from formulations.

A review on a medicinal plant belong to family Labiatae has been made in the Kingdom of Saudi Arabia. Among the reported flora in the Kingdom of Saudi Arabia, Labiatae family has the highest species. A total of 23 species of Labiatae family has been reported with high medicinal value. A detail review on 12 species of Labiatae family had done to know their phytochemical constituents, medicinal uses and pharmacological properties. In this review we also explore the total chemical constituents present in each plant with a unique list of 3D chemical structures. (E)-2-Hexenal, 1,8-Cineole, Bicyclogermacrene, Borneol, Bornyl acetate, Bulnesol, Caffeic acid, Camphene, Camphor, Eugenol, Gallic acid, Quercetin, Terpinene, Thymol, etc are the important constituent in these 12 species of Labiatae family. This study also shows that Marrubium vulgare L, Ocimum basilicum L, Origanum majorana and Otostegia fruticosa plants had reported with many medicinal uses and pharmacological properties. Medicinal constituents include the highest phenolic, flavonoid content and strong aromatic essential oil. Further scientific investigations on these 12 species are needed to explore toxicity and clinical efficacy and as well as to explore the therapeutic effects of major secondary metabolites. The summarized information from the current review may be a useful tool for researchers to carry out further study and explore other scientific aspects of the herbs.
