What are the most safe drug classes combinations for patient with: dyslipidemia and hypertension ( i am a pharmacist ) ?

Separate problems: I'm not aware of any anti-hypertensive that also lowers lipids (or vice versa). If indicated (doubtful if you're 22), a statin is the only class that has valid outcome data for lipids. For htn, starting with a diuretic like hctz (hydrochlorothiazide) makes the most sense. Adding an ace or arb (as combination therapy), if needed, would be my next step.
