Drotaverine hydrochloride is a type 4 cyclic nucleotide phosphodiesterase (PDE4) inhibitor and an L-type voltage-dependent calcium channel (L-VDCC) blocker, blocks the degradation of 3',5'-cyclic adenosine monophosphate. Drotaverine (hydrochloride) exhibits in vivo antispasmodic efficacy without anticholinergic effects.

In Vitro

Drotaverine hydrochloride is a relaxant for pre-contracted airways that shows concentration-dependent and medium-dependent effects. The ED ₅₀ for histamine, methacholine, and potassium chloride as contractile agents are 4.7×10^-5, 4.3×10^-5, and 2.2×10^-5 mol/L^[1].
Drotaverine hydrochloride suppresses bronchial contractions in guinea pigs, with ED ₅₀ values for histamine, methacholine, and potassium chloride being 8.5×10^-5, 9.3×10^-5, and 7.4×10^-5 mol/L^[1].
Drotaverine hydrochloride shows higher selectivity for KCl-induced contractions^[1].
Drotaverine hydrochloride inhibits the specific binding of nifedipine and diltiazem, with IC₅₀ values of 5.6 and 2.6 μM^[2].
Drotaverine hydrochloride significantly increases the dissociation rate constants (k^-1 (min^-1)) for nifedipine and diltiazem from the uterine membranes of pregnant rats to 0.055 and 0.062, respectively, with corresponding half-lives (t_1/2 (min)) of 5.55 and 4.9^[2].

Animal Model:	STZ-induced AD white mice ^[3]
Dosage:	10, 20, 40, 80 mg/kg; single dose
Administration:	Intraperitoneal injection (i.p.)
Result:	Increased physical activity in a dose-dependent manner, with more time spent in the open arms, increased in the number of crossings and time spent in the north quadrant. Increased in brain antioxidant levels (SOD, CAT, GSH), a reduction in nitrite levels, and significant increased in serotonin, dopamine, and norepinephrine levels.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.08 mg/mL (4.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL Corn oil, and mix evenly.
