IMRISEX is the IMMANX division's long-duration prescription therapy for erectile dysfunction. Tadalafil's extended half-life — well documented at 36 hours from a single dose — opens a category that sildenafil cannot serve: weekend-pill positioning, lower stigma, and a flexibility window that matches how real relationships actually work.

Each 5g sachet delivers a single 20mg dose of tadalafil in a pharmaceutical-grade oral jelly. The same format that made IMBOLDX a distributor favorite — now engineered for the longer pharmacological window.

5g ● Tadalafil 20mg
Tadalafil's hallmark. A single dose maintains plasma concentrations supporting therapeutic activity for up to 36 hours — by far the longest of any approved oral ED therapy. Distributor positioning writes itself.
A lower-strength 5mg daily formulation is in the IMRISEX product roadmap for distributor partners who want both weekend-pill and daily-management SKUs under one brand.
Same FDA-registered cGMP facility, same ICH Q7 documentation, same GS1-128 traceability. The IMMANX quality infrastructure scales by design — IMRISEX inherits everything from day one.
Tadalafil is one of the most extensively studied PDE5 inhibitors in clinical literature. The 36-hour pharmacological window — distinct from sildenafil's 4–6 hour window — is supported by FDA labelling and replicated across multiple Phase III trials.
Plasma concentrations maintain therapeutic activity for up to 36 hours after a single 20mg dose — the longest in-class duration available.
