The enervating side effects of chemotherapeutic drugs have necessitated the use of targeted drug delivery in cancer therapy. To that end, thermoresponsive hydrogels have been employed to improve the accumulation and maintenance of drug release at the tumour site. Despite their efficiency, very few thermoresponsive hydrogel-based drugs have undergon...

Tuberculosis (TB) remains a life-threatening infection, and it is well-known that effective TB treatment is associated with multiple drugs administered to infected patients on a daily basis. Terizidone (TZD) is an anti-TB drug used in the treatment of multi-drug resistant and extensively drug-resistant TB but presents with polyneuropathic adverse e...

The risk of secondary bacterial infections resulting from dental procedures has driven the design of antimicrobial and antifouling dental materials to curb pathogenic microbial growth, biofilm formation and subsequent oral and dental diseases. Studies have investigated approaches based primarily on contact-killing or release-killing materials. Thes...

The conventional approach in the tablet formulation of acetaminophen (ACM) suggests the use of five or more different excipients in a wet granulation tableting process. The use of many excipients in tablet formulation may negatively create excipient-excipient interactions, excipient-drug interactions, exaggerated product side effects, and high drug...

Nanocrystalline materials (NCM, i.e., crystalline nanoparticles) have become an important class of materials with great potential for applications ranging from drug delivery and electronics to optics. Drug nanocrystals (NC) and nano co-crystals (NCC) are examples of NCM with fascinating physicochemical properties and have attracted significant atte...

The present work reports two novel pharmaceutical co-crystals; 2:1 isoniazid-glutaric acid (INHGA) and 2:1 pyrazinamide-glutaric acid (PGA). Isoniazid and pyrazinamide are key first-line drugs used for the treatment of tuberculosis. The co-crystals were produced via solid-state and solvent assisted grinding methods. Thermal characteristics of the s...

Two pharmaceutical solid state co-crystals EFZA and NEF of two non-nucleoside reverse transcriptase inhibitors (efavirenz, EFV and nevirapine, NVP) and a nucleoside reverse transcriptase inhibitor, zidovudine (AZT) were prepared. Currently, these drugs are essential in various front-line HIV treatment regimens due to their potential in the manageme...

The determination of catechol-O-methyltransferase (COMT) activity is considered valuable for various pharmaceutical and biomedical research projects. A specific high performance liquid chromatography-coulometric electrochemical detection method, for the assay of COMT activity was developed by measuring the formation of normetanephrine from norepine...

The monitoring of endogenous hormone plasma levels could be valuable in biomedical, veterinary and pharmaceutical research. A specific high performance liquid chromatography method with diode array detection, for the assay of cortisol, corticosterone and melatonin in animal plasma was developed and validated. The chromatographic separation was achi...

The monitoring of monoamines and their metabolites in CNS samples can be very valuable in pharmaceutical and biomedical research. A specific high performance liquid chromatography, coupled to a coulometric electrochemical detection method, for the assay of monoamines (dopamine, norepinephrine, epinephrine and serotonin) and their metabolites in rat...

The suitability of the use of acetanilide, meso-erythritol and In-48Sn as phase change materials (PCMs) in latent heat thermal storage systems (LHTES) for cooking applications has been investigated under high charging and heat retrieval conditions. In-48Sn showed the greatest thermal stability up to 289.68 °C with meso-erythritol showing stability...

Recently, considerable interest developed in using newer/improved antibiotics for the treatment of Acne vulgaris. During this study, different roxithromycin solid-state forms (i.e. crystalline and amorphous) were encapsulated into vesicle systems (niosomes, proniosomes, ufosomes and pro-ufosomes) for dermis targeted delivery. Characterization of th...

p> Objective: This study was aimed at developing an HPLC method that would be suitable and sufficiently robust to analyze clarithromycin or spiramycin from bulk materials, amorphous solid dispersions as well as when included into solid dosage forms. Methods: A C₈ column (250 x 4.6 mm, 5 µm) was used as stationary phase, the mobile phase...
