Abstract:

In the present study, development of salbutamol sulphate nanoparticles that adhere to gastric mucus was investigated. Salbutamol sulphate has low bioavailability due to short transit time in gastric. It also has a positive surface charge that provides hurdles to be encapsulated by the positively strong mucoadhesive polymer of chitosan. To overcome the difficulties, the surface charge of active ingredient was modified using several nonionic and anionic stomach-specific polymers. The nanoparticles were prepared using ionotropic gelation technique. The evaluation involved determination of particle size, zeta potential, entrapment efficiency, in vitro drug release and in vitro mucoadhesion test. Results exhibited that the use of anionic alginate polymer was more satisfactory than that of nonionic polymer. Characteristics of the particles was nano-size, high encapsulation efficiency, fulfilled the drug release requirements and adhesive towards stomach for around 11 hours. This result shows that the salbutamol sulphate nanoparticles can be utilized for improvement its delivery.

Keywords: Mucoadhesive, salbutamol sulphate, nanosize, anionic polymer.

Abstract:

Aims of this research were to study the major religious festivals of merit making and joyful celebrations (nationwide) in each country of ASEAN countries and to compare the costumes for these major religious festivals among these countries. This documentary research employed qualitative research methodology. The findings of the research disclosed that there are 28 main religious festivals in ASEAN countries: 3 Islamic festivals in Brunei Darussalam such as Hari Raya Aidiladha Festival, Mauludin Nabi Festival and Hari Raya Aidilfitri Festival; 2 Buddhist festivals in Cambodia such as Pchum Ben Festival and Khmer New Year Festival; 3 Islamic festivals in Indonesia such as Eid al-Adha Festival, Maulid Nabi Festival and Eid ul-Fitr Festival; 5 Buddhist festivals in Laos such as Boun Awk Pansa Festival, Boun Pha Vet Festival, Boun Pi Mai Festival, Boun Khao Pradabdin Festival and Boun Khao Salak Festival; 3 Islamic festivals in Malaysia such as Hari Raya Aidil Adha Festival, Maulidur Rasul Festival and Hari Raya Aidilfitri Festival; 4 Buddhist festivals in Myanmar such as Thadingyut Festival, Tazaungmon Full Moon Festival, Htamane Festival, and Thingyan Festival; 2 Christian festivals in Philippines such as Christmas Festival and Feast of the Santo Niño; Only 1 Buddhist festival in Singapore: Festival of Vesak Day; 4 Buddhist festivals in Thailand such as Songkran Festival (Thai New Year), Sart Thai Festival, Khao Pansa Festival and Awk Pansa Festival; and only 1 Buddhist festival in Vietnam: Tet Nguyen Dan Festival. For the comparison of the costumes for these major religious festivals, it can be concluded that the most popular style of male costume for religious festivals in ASEAN countries consists of stand-up collar (100%), long sleeves (100%), shirt (90%), and long pants (100%), and the most popular style of male costume for religious festivals in ASEAN countries consists of round neck (90%), long sleeves (80%), blouse (60%), and maxi tube skirt (80%).
