DissolvA™ — Predictive Dissolution Suite
4s
Powered by AI
Core Capabilities
Everything you need
in one place.
From raw vessel data to regulatory-ready reports — no Excel macros, no local installs required.
Intelligent Compliance Engine
USP/FDA monograph compliance verified at Q-time via interpolation. Instant OOS flagging with academic root-cause analysis and ICH Q6A recommendations.
f1 / f2 Similarity Analysis
FDA-compliant f1 and f2 calculation with 85% cutoff, Q-value and Q-time overlays, error bars, and automatic boundary-zone warnings when f2 is in the 45–55 range.
62 Kinetic Models
Zero-order to Gompertz, Weibull variants, sigmoid, burst-release, and fractal models. More models than DDSolver (40), KinetDS (15), or RKinetDS (36).
Excel Report Engine
8-sheet professional reports with logo upload, project metadata, bootstrap results, dissolution charts, and similarity reports — all generated in one click.
Smart Profile Management
Session persistence across all pages. Profile renaming syncs globally across all analyses. Project metadata — name, analyst, description — flows into report headers automatically.
Statistical Analysis
MDT, DE, pooled statistics, per-profile tables with SD/RSD. Individual profile plots with error bars, Q-line overlays, and USP acceptance criterion annotation.
Predictive Dissolution Suite

M. Sinan KAYNAK, PhD

Anadolu University, Faculty of Pharmacy

★★★★★

"DissolvA brings together everything pharmaceutical scientists need — kinetic modeling, regulatory compliance, and professional reporting — in a single, elegant web platform."

AY

Ayşe Yılmaz, PhD

Hacettepe University, Pharmaceutical Technology

★★★★★

"Bootstrap f2 analizi için artık ayrı bir yazılıma ihtiyaç duymuyorum. DissolvA ile tüm süreç tek platformda tamamlanıyor, hem hızlı hem güvenilir."

RK

Rahul Krishnamurthy

Senior Formulation Scientist, Mumbai

★★★★★

"The 62-model kinetic library is unmatched. I switched from DDSolver after the first session. The Excel report output alone saves me hours each week."

MB

Marta Borkowska

Regulatory Affairs, Warsaw Pharma CRO

★★★★★

"FDA and EMA compliance checks in one click. The USP monograph engine flagged an OOS result our team had missed. This tool has real regulatory depth."

JL

Jian Li, PhD

R&D, Shenyang Pharmaceutical University

★★★★★

"We use DissolvA for IVIVC preparatory work across multiple BCS Class II projects. The profile management and SD band visualizations are exceptional."

EO

Emeka Okafor

Bioequivalence Analyst, Lagos

★★★★★

"No install, no macro, no Excel version compatibility issues. Just open the browser and analyze. DissolvA is exactly what dissolution science needed."

SN

Sofia Navarro, MSc

PhD Candidate, Universidad de Barcelona

★★★★★

"As a PhD student I needed a tool that matched academic rigor. DissolvA cites the correct FDA and EMA guidance at every step — I can trust the output in my thesis."

TW

Thomas Weber

QA Lead, Swiss Generics Manufacturer

★★★★★

"The nonparametric bootstrap f2 with Shah 1998 methodology gives us the statistical confidence our QA submissions require. This is serious pharmaceutical software."

PR

Priya Rajan, PhD

Formulation Scientist, Bangalore

★★★★★

"Switched from DDSolver six months ago. The smart model recommendation feature alone saved my team dozens of hours of trial-and-error fitting. Remarkable tool."

KM

Kenji Matsuda

Dissolution Lab Manager, Osaka

★★★★★

"Our dissolution lab adopted DissolvA as the standard reporting tool. The branded Excel export with professional charts is exactly what our clients expect."
