Removal of the widespread used drug paracetamol from water was investigated using activated carbon originated from dende coconut mesocarp and babassu coconut mesocarp. Kinetic and equilibrium data were obtained at different values of pH. Both activated carbons showed high efficiency when pH ≤ pHPZC as the carbonil group of paracetamol molecule are adsorbed due to positively charged carbon surfa...

BACKGROUND Ibuprofen and paracetamol differ in their mode of action and related therapeutic effects, suggesting that combined administration may offer improved analgesia. Reported here are the results of two studies on the pharmacokinetic properties of a novel ibuprofen (200 mg) and paracetamol (500 mg) fixed-dose combination tablet. METHODS Both studies were open-label, randomised studies in...

Background: Despite the widespread use of dose administration aids (DAAs) there is little available data on the stability of drugs during repackaging or storage in these devices. Aim: To investigate the physicochemical stability of paracetamol tablets repackaged in DAAs. Method: Physicochemical stability studies were performed on a commonly used paracetamol tablet directly after heat-sealing in...

In India, paracetamol is available in many formulations such as liquid suspension, drops, tablets, injection, rectal suppositories with varying concentrations (120/125/150/ 250/500 mg/5 mL). The usual cause of paracetamol overdose is frequent administration of the drug round the clock by an anxious parent who regards fever as a potential dangerous event and as a trigger for febrile seizures. Un...

Objectives: The aim of this prospective randomized, double-blind study was to evaluate the analgesic efficacy and opioidsparing effects of preemptive single dose of dexketoprofen trometamol in comparison with that of paracetamol or placebo for elective lumbar disc surgery, over a 24-hour (h) investigation period. Methods: After institutional approval and informed consent had been obtained, 75 p...

A woman aged 30, an inmate of a mental institution, was admitted to hospital two hours after ingesting at least 50 paracetamol tablets. She had been discovered while still swallowing some of the drug, and gastric lavage was carried out almost immediately. She had been under psychiatric care since adolescence and had received various drug therapies. Currently she was taking nortriptyline, 25 mg....

This study evaluates the disintegrant properties--tablet disintegration time (DT) and crushing strength--friability/disintegration time (CSFR/DT) ratio of a paracetamol tablet formulation prepared with sorghum and plantain starches in comparison with corn starch BP. The effects of disintegrant concentration, relative density of tablets and the mode of disintegrants addition were studied. The st...

A 23 factorial experimental design has been used to quantitatively study individual and interaction effects of the nature of binder (N), concentration of binder (C) and the applied pressure (P) on two mechanical properties, namely, tensile strength (TS) and brittle fracture index (BFI), of paracetamol tablets. The factorial design was also used to study the quantitative effects of coprocessing ...
