The expression of CBRs might be affected by the use of tocolytic agents or corticosteroid therapies, commonly used for fetal lung maturation. Research by Pagano et al. highlighted the possible tocolytic effects of cannabis consumption [49]. There are no studies directly linking tocolysis administration with changes in CBR expression. Similarly, the impact of betamethasone and dexamethasone on CBR expression in the placenta has not been explored. Interestingly, a study on broilers indicated an elevated expression of the CBR1 in the broiler hypothalamus after 72 hours of administration [50]. However, the effects on the hypothalamus and placenta might differ and further studies are needed to evaluate the influence of those factors. Our study did not reveal any significant influence of tocolytic or steroid administration during pregnancy.
