Galantide do not activate the K ⁺ conductance but produces a concentration-dependent antagonism (IC ₅₀ =4 nM) of the galanin-induced increase in K ⁺ conductance. Galantide acts like galanin and inhibits the voltage-dependent Ba2+ current (IBa). The inhibition of IBa also is concentration dependent (IC ₅₀ =16 nM) and the maximum inhibition produced by galantide is approximately 40%.

Intracerebroventricular injection of galanin (5 micrograms/rat) inhibited sexual behavior in experienced male rats--without producing any other locomotor or behavioral deficit-, injection of the galanin antagonist, galantide, by the same route (1 or 2 micrograms/rat) stimulated sexual behavior (improving arousal, motivation and performance indexes) and antagonized the effect of galanin. Galantide ameliorates mild acute pancreatitis (AP). Galantide significantly reduces AP-induced hyperenzymemia by 41–49%. Galantide has been found to improve social memory in 'socialrecognition' test when i.c.v. administered at doses varying from 6-6000 nM.
