Abstract:
Oxybutynin is an important anticholinergic agent that prevents uncontrolled contractions in the treatment of overactive bladder (OAB). However, drugs containing oxybutynin have significant side effects such as dry eyes, dry mouth, increased heart rate, constipation, blurred vision, and confusion. In recent years, new delivery methods for this agent are being searched. One of them is vaginal delivery. In this study, we aimed to compare the effects of oxybutynin on oxidative parameters in the potential target tissues of the oral and vaginal delivery. Female New Zealand white rabbits (n=12) were divided into two groups: oral delivery and vaginal delivery. The animals were sacrificed 48 h after administration and nitric oxide (NOx), thiobarbituric acid-reactive substances (TBARs), and glutathione (GSH) levels were determined spectrophotometrically in the aorta, salivary gland, and small intestine tissue samples. Vaginal delivery significantly decreased NOx levels in all tissue samples as compared to oral delivery (p < 0.05). Moreover, it reduced TBARs levels in salivary gland and aorta tissue samples (p < 0.05). In the light on these findings, it can be said that vaginal delivery may decrease the oxidant-induced side effects of oxybutynin as compared to oral delivery.
Insights
Vaginal oxybutynin delivery may reduce oxidative stress and side effects compared to oral administration for overactive bladder. This study compared oral versus vaginal oxybutynin effects on oxidative parameters in rabbits.
Area of Science:
- Pharmacology
- Urology
- Toxicology
Background:
- Oxybutynin, an anticholinergic, treats overactive bladder (OAB) but causes side effects.
- New drug delivery methods are sought to mitigate oxybutynin's adverse effects.
- Vaginal delivery is explored as an alternative route for oxybutynin administration.
Purpose of the Study:
- To compare the effects of oral versus vaginal oxybutynin delivery on oxidative stress parameters.
- To investigate tissue-specific changes in nitric oxide (NOx), TBARs, and glutathione (GSH) levels.
Main Methods:
- Female New Zealand white rabbits (n=12) were divided into oral and vaginal oxybutynin delivery groups.
- Animals were sacrificed 48 hours post-administration.
- Spectrophotometric analysis of NOx, TBARs, and GSH levels in aorta, salivary gland, and small intestine tissues.
Main Results:
- Vaginal delivery significantly reduced NOx levels in all tested tissues compared to oral delivery (p < 0.05).
- Vaginal administration also decreased TBARs levels in salivary gland and aorta tissues (p < 0.05).
- No significant differences in GSH levels were reported between the groups.
Conclusions:
- Vaginal oxybutynin delivery demonstrates a potential to mitigate oxidative stress.
- This route may reduce the incidence of oxidant-induced side effects associated with oral oxybutynin.
- Further research into vaginal oxybutynin delivery for OAB management is warranted.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
