Selective alpha-1A adrenergic antagonist targeting receptors in prostate and bladder neck smooth muscle. Uroselective with less vascular effects.
Limited veterinary data. More uroselective than prazosin (less hypotension). May facilitate ureteral stone passage. GI upset possible.
Species-specific contraindications and adverse-reaction reports for dog may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Tamsulosin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in dog — the rules above are the citations specific to this species, not generic recommendations.
