Synthesis and Structure-Activity Relationships of Novel Benzofuran Derivatives with Osteoblast Differentiation-Promoting Activity.

Osteoporosis is caused by an imbalance between bone resorption and formation, which decreases bone mass and strength and increases the risk of fracture. Therefore, osteoporosis is treated with oral resorption inhibitors, such as bisphosphonates, and parenteral osteogenic drugs, including parathyroid hormone and antisclerostin antibodies. However, orally active osteogenic drugs have not yet been developed.

We describe the utility of 'folic and folinic acid load tests' in the investigation of a 26-year-old woman with persistently low serum folate and moderate hyperhomocysteinaemia unresponsive to folic acid supplements. Serum folate, plasma 5-methyltetrahydrofolate (5-MTHF), red cell 5-MTHF and plasma total homocysteine at baseline, 2-h, 4-h and 2- or 4-days (if applicable) post administration of a large dose of oral folic acid, or oral or parenteral folinic acid were measured. The tests confirmed non-compliance but also suggested an unsuspected possible defect in the folate pathway based on differential response to folic versus folinic acid supplements.

Cardiol Rev
October 2024
From the Department of Medicine, New York Medical College, Valhalla, NY.
Ophthalmologic drugs may be delivered to the eye via a number of ways, including topical drops and gels, intraocular injections, and parenteral or oral administration. The inadvertent systemic absorption of these drugs may lead to a myriad of side effects, ranging from benign cosmetic changes to potentially fatal cardiovascular complications. Historically, glaucoma treatment, including β-blockers and α-agonists, have been particularly examined for such events.

The authors conducted a trial to establish the efficacy and safety of glepaglutide in reducing parenteral support (PS) needs in patients with SBS with intestinal failure.
Methods: In an international, placebo-controlled, randomized, parallel-group, double-blind, phase 3 trial, patients with SBS with intestinal failure requiring PS ≥3 d/wk were randomized 1:1:1 to 24 weeks of glepaglutide 10 mg twice weekly or once weekly or placebo.
Does needle clogging change the spatial distribution of injected drug in tissue? New insights by X-ray computed tomography.

Prefilled syringes (PFS) are primary packaging materials that offer convenience and safety for subcutaneous injection of parenteral drug solutions. However, an increasingly common problem with the trend towards higher drug concentrations is the clogging of the needle during storage due to evaporative water loss and consequent solidification of the drug. In contrast to all previous studies on this topic, this work focuses on pharmacokinetically relevant aspects and investigates the effects of needle clogging on the spatial distribution of the injected drug in the tissue.
