Drug-induced Subacute Cutaneous Lupus Erythematosus Caused by a Topical Beta Blocker - Timolol.

Drug-induced lupus erythematosus (DI-LE) is an autoimmune condition secondary to a recent pharmacological intervention. There are no established specific diagnostic criteria for DI-LE, and the disease is recognized based on the medical history of the patient. Typically, the onset is closely related to a recent drug exposure, and the disease terminates after discontinuation of the inducing factor. ...

A transgenic mouse model for HLA-B*57:01-linked abacavir drug tolerance and reactivity.

Adverse drug reactions (ADRs) are a major obstacle to drug development, and some of these, including hypersensitivity reactions to the HIV reverse transcriptase inhibitor abacavir (ABC), are associated with HLA alleles, particularly HLA-B*57:01. However, not all HLA-B*57:01+ patients develop ADRs, suggesting that in addition to the HLA genetic risk, other factors may influence the outcome of the r...

Drug-Gut Microbiota Interactions: Implications for Neuropharmacology.

The fate and activity of drugs are frequently dictated not only by the host per se but also by the microorganisms present in the gastrointestinal tract. The gut microbiome is known to, both directly and indirectly, affect drug metabolism. More evidence now hints at the impact that drugs can have on the function and composition of the gut microbiome. Both microbiota-mediated alterations in drug met...

A comprehensive review on contact lens for ophthalmic drug delivery.

With the prevalence of electronic devices and an aging population, the number of people affected with eye disease is increasing year by year.

Modelling the delay between pharmacokinetics and EEG effects of morphine in rats: binding kinetic versus effect compartment models.

Drug-target binding kinetics (as determined by association and dissociation rate constants, k and k ) can be an important determinant of the kinetics of drug action. However, the effect compartment model is used most frequently instead of a target binding model to describe hysteresis. Here we investigate when the drug-target binding model should be used in lieu of the effect compartment model. T...

Nanogels as potential drug nanocarriers for CNS drug delivery.

Hydrogel-based drug delivery systems (DDSs) have versatile applications such, as tissue engineering, scaffolds, drug delivery, and regenerative medicines. The drawback of higher size and poor stability in such DDSs are being addressed by developing nano-sized hydrogel particles, known as nanogels, to achieve the desired biocompatibility and encapsulation efficiency for better efficacy than convent...
