Formulation, development, in vivo pharmacokinetics and pharmacological efficacy evaluation of novel vaginal bioadhesive sustained core-in-cup salbutamol sulphate tablets for preterm labor

A systematic review of mucoadhesive vaginal tablet testing

Drug administration through the vaginal tract is one of the oldest modalities of pharmacotherapy, and it is also one of the most explored. Since the vaginal cavity has a wide surface area, a plentiful blood supply, and a complex network of blood arteries, it can evade hepatic first-pass metabolism and obtain high local drug concentrations. Vaginal pills look to be a good dose form since they are simple to use, portable, and can easily deliver the required amount of medicine. Vaginal formulations, on the other hand, are vulnerable to rapid expulsion due to the vaginal tract’s self-cleaning action, which reduces the formulation’s efficiency. Currently, there is an increasing amount of focus on mucoadhesive vaginal formulation research and development to fix the formulation at the place where the medicine can be released and/or absorbed. This article examines all of the strategies used by researchers to develop a mucoadhesive vaginal tablet that is safe, effective, and comfortable for the user.

β-MnOOH nanoplate-enhanced chemiluminescence reaction and its application to the determination of amoxicillin and salbutamol sulfate

In this research, β-MnOOH nanoplates (NPLs) were hydrothermally produced and then identified using several spectroscopic methods. The β-MnOOH NPLs were used to catalyze the chemiluminescence (CL) reaction of NaHCO₃ -H₂ O₂ . To validate the capability of the CL reaction for pharmaceutical analysis, the CL reaction of β-MnOOH NPLs-NaHCO₃ -H₂ O₂ reaction was exploited to develop a new method of measuring antibiotics named amoxicillin (AMX) and salbutamol sulfate (SLB). This method is based on the attenuating β-MnOOH NPLs-NaHCO₃ -H₂ O₂ CL reaction by the antibiotics. Calibration curves were linear in the range 3.00 × 10^-5 to 1.00 × 10^-3  mol L^-1 for AMX and in the range 1.00 × 10^-5 to 1.00 × 10^-4  mol L^-1 for SLB. The limits of detections obtained using the CL method for AMX and SLB were 8.90 × 10^-6  mol L^-1 and 5.60 × 10^-6  mol L^-1 , respectively. The relative standard deviations for AMX and SLB, at the 5.00 × 10^-5  mol L^-1 concentration, were 2.44% and 2.57% (n = 5), respectively. The study of the effect of foreign species showed that the CL method developed has the appropriate selectivity for AMX and SLB. The success of the CL method in actual samples analysis was demonstrated by accurately measuring the selected antibiotics in the pharmaceutical formulations.

Biopolymers have gained tremendous attention in many daily life applications, including medical applications, in the past few years. Obstetrics and gynecology are two fields dealing with sensitive parts of the woman's body and her newborn baby, which are normally associated with many issues such as toxicity, infections, and even gene alterations. Medical professions that use screening, examination, pre, and post-operation materials should benefit from a better understanding of each type of material's characteristics, health, and even environmental effects. The underlying principles of biopolymer-based materials for different obstetric and gynecologic applications may discover various advantages and benefits of using such materials. This review presents the health impact of conventional polymer-based materials on pregnant women's health and highlights the potential use of biopolymers as a safer option. The recent works on utilizing different biopolymer-based materials in obstetric and gynecologic are presented in this review, which includes suture materials in obstetric and gynecologic surgeries, cosmetic and personal care products, vaginal health, and drug delivery; as well as a wound dressing and healing materials. This review highlights the main issues and challenges of biopolymers in obstetric and gynecologic applications.
