Neonatal and pediatric oral drug delivery: Hopes and hurdles.

The neonatal and pediatric populations have long been neglected concerning the development of oral dosage forms. For close to two decades, caregivers have had to adjust the doses of the off-label medicines and drugs for adults to suit the neonatal and pediatric needs. This is due to the lack of rules and regulations regarding neonates and pediatrics clinical trials while pharmaceutical industries see this as a non-lucrative approach.

Development and evaluation of natural gum-based extended release matrix tablets of two model drugs of different water solubilities by direct compression.

The study was aimed at developing extended release matrix tablets of poorly water-soluble diclofenac sodium and highly water-soluble metformin hydrochloride by direct compression using cashew gum, xanthan gum and hydroxypropylmethylcellulose (HPMC) as release retardants. The suitability of light grade cashew gum as a direct compression excipient was studied using the SeDeM Diagram Expert System. Thirteen tablet formulations of diclofenac sodium (∼100 mg) and metformin hydrochloride (∼200 mg) were prepared with varying amounts of cashew gum, xanthan gum and HPMC by direct compression.
