Chemical Information and Compositions of Dapoxetine 60mg

For researchers, biochemists, and wholesale distributors, the molecular structure of dapoxetine 60mg is a classic example of targeted pharmacokinetic engineering. Understanding its composition is vital for analytical testing, formulation, and predicting its biological behavior.

Official Chemical Nomenclature

  • Chemical Name (Base): (S)-N,N-dimethyl-3-(naphthalen-1-yloxy)-1-phenylpropan-1-amine
  • Chemical Name (HCl Salt): (S)-N,N-dimethyl-3-(naphthalen-1-yloxy)-1-phenylpropan-1-amine hydrochloride
  • Chemical Formula: C21H23NO · HCl (as the Hydrochloride salt)
  • Molecular Weight: 341.87 g/mol (as the Hydrochloride salt); 305.41 g/mol (as the Dapoxetine base)
  • CAS Number: 129938-20-1 (Hydrochloride salt); 38913-72-3 (Base)

Structural Composition Breakdown

dapoxetine 60mg is a structural analogue of Fluoxetine (Prozac), but with critical modifications that dictate its unique pharmacokinetic profile.

  1. The Naphthalene Ring: Unlike Fluoxetine, which utilizes a trifluoromethyl-substituted phenyl ring, Dapoxetine features a large, rigid naphthalene ring system connected via an ether linkage. This bulky, lipophilic moiety significantly enhances the molecule’s affinity for the Serotonin Transporter (SERT) while altering its metabolic pathways, making it highly susceptible to rapid hepatic oxidation.
  2. The Oxy-Propanamine Chain: The core of the molecule features the standard SSRI 3-carbon chain connecting the ether oxygen to the amine group.
  3. The Stereochemistry (S-Enantiomer): Dapoxetine exists as a chiral molecule. The commercial drug is the pure (S)-enantiomer. The S-enantiomer is responsible for the potent serotonin reuptake inhibition. The R-enantiomer is significantly less active and contributes only to metabolic burden, hence its exclusion from the formulation.
  4. The Hydrochloride Salt: The Dapoxetine base is a lipophilic, oily substance that is impossible to compress into a stable tablet. It is converted into the Hydrochloride salt to create a stable, water-soluble, crystalline powder suitable for oral bioavailability and precise tableting.

Physical and Chemical Properties

  • State at Room Temperature: Solid (Crystalline Powder)
  • Color: White to off-white
  • Solubility: Freely soluble in water, ethanol, and methanol; slightly soluble in chloroform and dichloromethane. Its high aqueous solubility as an HCl salt contributes to its rapid gastrointestinal absorption.
  • Melting Point: Approximately 192°C to 194°C (with decomposition).

Pharmacokinetics (The “On-Demand” Profile)

The pharmacokinetics of dapoxetine 60mg are its defining clinical feature, designed specifically for “as-needed” dosing.

  • Absorption: Rapidly absorbed. Peak plasma concentration (Cmax) is reached within 1 to 2 hours (Tmax) post-dose.
  • First-Pass Metabolism: It undergoes extensive first-pass metabolism in the liver (CYP2D6 and CYP3A4 enzymes). This means a significant portion of the oral dose is destroyed before reaching the systemic circulation, but what does reach the brain hits rapidly and potently.
  • Half-Life: The terminal elimination half-life is approximately 1.5 hours (range 1.3–1.6 hours). This is drastically shorter than Fluoxetine (2-4 days) or Paroxetine (21 hours). The short half-life ensures that the drug is almost entirely cleared from the bloodstream within 24 hours, preventing accumulation and eliminating the need for a washout period.
  • Excretion: Metabolites are primarily excreted in the urine.

Formulation Details: The 60mg Pill

When you source wholesale dapoxetine 60mg, you are sourcing the Hydrochloride salt formulation.

A critical formulation nuance for B2B buyers and analytical labs: A dapoxetine 60mg pill contains 60mg of Dapoxetine Hydrochloride, which equates to approximately 53.5mg of Dapoxetine base. When verifying API mass via HPLC, this salt-to-base conversion factor must be accounted for.

Standard excipients used in the tableting process include:

  • Lactose Monohydrate: Diluent/filler.
  • Microcrystalline Cellulose (MCC): Binder and filler.
  • Croscarmellose Sodium: Super-disintegrant.
  • Colloidal Silicon Dioxide: Glidant.
  • Magnesium Stearate: Lubricant.

For wholesale buyers, ensuring the uniform blending of 60mg of API within the excipient matrix via geometric dilution is critical to guarantee dosing consistency across massive batches.
