FILM COATING TECHNOLOGY: AN OVER VIEW

Film coating technology is now a days very important in the field of pharmacy particularly in formulation development. In the last 25 years tablet coating has undergone several fundamental changes. Many modifications were advocated to improve the basic process and film coating chosen in place of sugar coating. Film coating is the process whereby a tablet, capsule, or pellet is surrounded by a thin layer of polymeric material. Tablet film coating is performed by two types, one is aqueous film coating (generally water is used as a solvent) and non aqueous film coating (generally organic solvent are used). Film coating formulations usually contain Polymer, Plasticizer, Colourants / Opacifiers, Solvent / Vehicle. Many film coating materials have functional properties which enable the creation of sustained or delayed (enteric) release dosage forms. Coating solution composition may affect the quality of final coated tablets. Optimization of composition of film coating solution is also required. This article discusses tablet coating process, film coating, process parameters, film coating advantages and applications, components of film coating, evaluation of film coated tablets, film defects etc.


NEED FOR EFFICACY, SAFETY, QUALITY CONTROL AND REGULATORY GUIDELINES FOR PHYTOPHARMACEUTICALS

This review paper highlights the current advances in knowledge about the safety, efficacy, quality control and regulatory aspects of Phytopharmaceuticals. The growing use of Phytopharmaceuticals (drug and other products derived from plants) by the public is forcing moves to evaluate the health claims of these agents and to develop standards of quality and manufacture. At present there is almost no policy worth its name to regulate the procurement and sale of medicinal plants in developing countries. Finally, the trend in the domestication, production and biotechnological studies and genetic improvement of medicinal plants, instead of the use of plants harvested in the wild, will offer great advantages, since it will be possible to obtain uniform and high quality raw materials which are fundamental to the efficacy and safety of herbal drugs.It is clear that the herbal industry needs to follow strict guidelines and that regulations are needed. This paper presents the element of methods of different aspects on efficacy, safety, quality control and standardization of herbal drugs and formulation. It is followed by international guidelines of WHO for manufacture quality control and evaluation of botanicals. Herbal drugs regulations in India is discussed in detail, followed by an overview of regulatory status of herbal medicine in USA, China, Australia, Brazil, Canada and Germany.


PRENATAL NUTRITION; NUTRIENT RECOMMENDATIONS BEFORE, DURING & AFTER PREGNANCY

Nutrition  before and during pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life. Prenatal nutrition addresses nutrient recommendations before and during pregnancy. Birth weight of the newborn at delivery reflects the sufficiency and the quality of maternal nutrient for the fetus during pregnancy. Prenatal nutrition has a strong influence on birth weight and further development of the infant.The present paper reviews the role of  prenatal nutrition in pregnancy.

ANDROPAUSE-MALE MENOPAUSE

Andropause is an age-related decline of testosterone in men that is gaining recognition as the world population becomes more aged. The diagnosis is based on clinical signs and symptoms supported with laboratory confirmation of low serum testosterone levels. The benefit of testosterone replacement therapy (TRT) for andropause has been well documented, but it requires careful monitoring...\\
