RP-HPLC-Based Bioanalytical Method Development and Validation for Tadalafil Identification in Spiked Human Plasma

For the purpose of determining the presence of Tadalafil in spiked human plasma, a precise, user-friendly, and repeatable RP-HPLC technique remained created & verified using Sildenafil as an internal reference. The Cromasil C18 (250mmx 4.6 ID, particle size:5 micron) column remained used to complete a chromatographic partition. The mobile phase used was methanol: water in a ratio of 15:85% v/v, at pH 2.5.0, with a binary gradient system maintaining a flow rate of 0.8ml/min. The drug sample’s discovery wavelength was 284nm. Ethyl acetate was used as the extracting solvent in the extraction process. It was discovered that Tadalafil has a retention time of 3.7 minutes. It was discovered that the procedure was liner within the concentraion series of 0.4-6.4ug/ml. The value of the lmit of quatation was discovered to 0.69. The precision and accuracy within the selected range are both intra- and inter-day. It was shown that the recovery studies ranged from 98.6 to 100.2%. It was discovered that the RSD ranged from 0.06-2.50%. The results showed that all parameters from the tampered human plasma were valid. The suggested RP-HPLC approach can be used for therapeutic medication monitoring and pharmacokinetic investigations. It is very quick and accurate at determining the presence of Tadalafil in human plasma.
