Typical dose
2-3mg/kg Weekly for 6 weeks then PRN
Route
Subcutaneous, Oral
Cycle length
6 weeks loading, then maintenance
Evidence
Limited human data

Mechanism

How it works

PPS works like a protective blanket for joints and bladder — it covers damaged cartilage and bladder lining, reducing inflammation and preventing further wear.

PPS is a semi-synthetic glycosaminoglycan that reduces cartilage degradation, inhibits inflammatory cytokines (IL-6, TNF-α), and restores bladder glycosaminoglycan layer.

In depth

Full profile

What it does

Less joint pain, easier movement, and less bladder pain.

How it works

PPS works like a cozy blanket for your joints and bladder. It covers the sore, worn-out spots, calms down swelling, and stops them from wearing out more.

It stops the things that break down your joint cushion. It also grabs onto and protects the worn-out parts of your joints.

What to expect

Less pain in 2-4 weeks. Joint cushion help shows up in 6-12 weeks.

  • Weeks 2-3: Your joints hurt less.
  • Weeks 4-6: You can move around better and more easily.
  • Weeks 8-12: Long-term help that protects your joint cushions.

Good to know

  • Get your blood checked to watch the tiny cells that help you stop bleeding
  • Don't use it with blood-thinning medicines
  • Tell your doctor if you get bruises for no reason

Staying safe

  • A sore spot where you got the shot
  • A little upset tummy
  • Hair getting thinner for a while (it grows back)

Avoid if you have:

  • People who bleed too easily
  • People with too few of the cells that help stop bleeding
  • People who are pregnant or breastfeeding
  • People who just had surgery

Qué hace

Menos dolor articular, movimiento más fácil y menos dolor vesical.

Cómo funciona

El PPS actúa como una manta acogedora para tus articulaciones y vejiga. Cubre las zonas doloridas y desgastadas, calma la hinchazón y evita que se desgasten más.

Detiene las sustancias que descomponen el cojín de tus articulaciones. También se une y protege las partes desgastadas de tus articulaciones.

Qué esperar

Menos dolor en 2-4 semanas. La ayuda para el cojín articular se nota en 6-12 semanas.

  • Semanas 2-3: Tus articulaciones duelen menos.
  • Semanas 4-6: Puedes moverte mejor y con más facilidad.
  • Semanas 8-12: Ayuda a largo plazo que protege los cojines de tus articulaciones.

Bueno saber

  • Hazte análisis de sangre para vigilar las plaquetas
  • No lo uses con medicamentos que adelgazan la sangre
  • Avísale a tu médico si te salen moretones sin razón

Manteniéndose seguro

  • Un punto doloroso donde te pusiste la inyección
  • Un poco de malestar estomacal
  • El cabello se adelgaza un poco por un tiempo (vuelve a crecer)

Evitar si tienes:

  • Personas que sangran con facilidad
  • Personas con muy pocas células que ayudan a detener el sangrado
  • Personas que están embarazadas o en lactancia
  • Personas que acaban de someterse a una cirugía
