Orodispersible tablets, usually prepared using freeze-drying method, are becoming a popular drug formulation for patients who have difficulties swallowing solid dosage forms. The influence of drug solubility and concentration on the physical characteristics of lyophilized tablets composed of mannitol and gelatin was investigated. Phenobarbital and phenobarbital sodium were studied as model drug...

Motivated by recent experiments on bilayer polyhedra composed of amphiphilic molecules, we study the elastic bending energies of bilayer vesicles forming polyhedral shapes. Allowing for segregation of excess amphiphiles along the ridges of polyhedra, we find that bilayer polyhedra can indeed have lower bending energies than spherical bilayer vesicles. However, our analysis also implies that, co...

Risperidone is a white to slightly beige powder. It is practically insoluble in water, freely soluble in methylene chloride, and soluble in methanol and 0.1 N HCl. RISPERDAL® tablets are available in 0.25 mg (dark yellow), 0.5 mg (red-brown), 1 mg (white), 2 mg (orange), 3 mg (yellow), and 4 mg (green) strengths.

Purpose: To evaluate a weakly cationic exchange poly(methacrylic acid-co-divinylbenzene) resin (PMD) as a new filler-binder for direct compression tablets. Methods: Powder properties of PMD and MCC were characterized. Tablets made from PMD and MCC with and without propranolol hydrochloride were evaluated for diameter, thickness, friability, assay, disintegration, dissolution and compression beh...

OBJECTIVES To assess the efficacy of Fuhuang Tablets in treating internal hemorrhoid hemorrhage and discussing the design and quality control of clinical trials of traditional Chinese medicine. METHODS According to two-center, randomized, blinded and controlled study, 144 patients with internal hemorrhoids were divided into 2 groups. Seventy-two patients were treated with Fuhuang Tablets (4 t...

OBJECTIVE Branding medication with a known pharmaceutical company name or product name bestows on the drug an added assurance of authenticity and effectiveness compared to a generic preparation. This study examined the impact of brand name and generic labeling on medication effectiveness and side effects. METHOD 87 undergraduate students with frequent headaches took part in the study. Using a...

The clinical application of sirolimus (SRL) as an immunosuppressive agent is largely hampered by its narrow therapeutic range. This study focused on developing SRL tablets with a sustained release profile for better safety. SRL was highly water insoluble and its solubility has been efficiently enhanced by preparing self-microemulsifying drug delivery system (SMEDDS). The SRL-SMEDDS was physical...

Rizatriptan benzoate has established its potential in controlling the symptoms of migraine. The present study aims formulate bilayer tablet rizatriptan multi release unit matrix embedded sustained layer achieve pulsatile drug control various phases A preliminary on four matrice...

Background: Ecstasy, mainly composed of 3,4-methylenedioxymethamphetamine (MDMA), is one of the most popular addictive synthetic drugs. This study was aimed to investigate the amount of MDMA in the ecstasy tablets seized in West Azerbaijan province, northwest Iran and also to assess the relationship between the physicochemical and morphological characteristics of the tablets. Methods: MDMA cont...
