Update: October 2018

No-SPA (NO-SPA) – a popular drug that provides fast
antispasmodic effect on smooth muscle.
It is applied for:

  • etiotropic therapy to eliminate muscle spasm,
    serving as the basis of the pathological condition;
  • symptomatic treatment of smooth muscle spasm which is
    a symptom of the disease, without affecting its pathogenesis;
  • premedication during the preparation of patients to some
    procedures (catheterization of ureters, urethra

Since the drug acts solely on smooth muscles, its
practice in situations where there are contraindications to
antispasmodics from the group of anticholinergic blockers (hypertrophy
prostate, glaucoma).

Pharmacological group: myotropic antispasmodic.

Drotaverinum or No-shpa

Surely each of us had to take the famous yellow
tablets with a special finish for those or other problems with
health The composition of the drug is the active substance.
Drotaverine, and it is under this name that the most
popular competitor No-shpy and similar in composition. What’s the difference
between Drotaverinum and No-spoy?

Having studied the instructions for the drugs, it becomes clear that the composition and
principle of action, and the effect is similar. therefore
a reasonable question arises – is there any sense to overpay for no-shpu?
No-shpa is an original drug patented drug

on the manufacturer: the quality of raw materials, production control,
The safety of the drug must be top notch. For,
to obtain a patent, the drug must comply with a number of strict
requirements and undergo the necessary clinical trials.

Drotaverine is a generic drug offered to consumers under
international, which means unpatented name. Clinical
The effectiveness of generics is not fully proven because
this group of drugs are put forward less stringent

It turns out that the patented drug is exposed to more
the number of tests before getting to the pharmacy counter. but
This does not mean that the generic negatively affects

pharmachologic effect

Drotaverine hydrochloride is an isoquinoline derivative with potent
antispasmodic effect on smooth muscle. This effect
possible by inhibiting an enzyme called PDE

PDE is involved in the hydrolysis reaction of cAMP to AMP. Inhibition
phosphodiesterase is characterized by an increase in the concentration of cAMP,
triggering a chain reaction. cAMP in high concentrations is
activator of cAMP-dependent phosphorylation of MLCK (lung kinase
chains of myosin). This leads to a decrease in the affinity of MLCK to
Ca2 + -calmodulin complex, and inactivated form KLCM
creates muscle relaxation.

cAMP affects the cytosolic concentration of the Ca2 + ion, lowering it.
This is due to the stimulation of Ca2 + transport to the sarcoplasmic
reticulum and extracellular space.

The effectiveness of drotaverine hydrochloride depends on the concentration
phosphodiesterase enzyme in tissues, which is significantly

Hydrolysis of cAMP in the muscle tissue of the heart and smooth muscles
vessels is performed using PDE3 isoenzyme. This explains
no serious adverse reactions from the CCC
antispasmodic activity.

Selective PDE4 inhibitors, which is Drotaverine, can
reduce the sensitivity of the uterus to the action of the hormone oxytocin and
lead to accelerated relaxation of the muscular tissue of the body that
allows you to stop preterm labor.

In addition to the antispasmodic effect, drotaverine reduces swelling and
muscle inflammation. Elimination of spasm leads to improvement
