Cialis and Malegra are both medications used to treat erectile dysfunction (ED), but they have different active ingredients and mechanisms of action.
Cialis (Tadalafil):
Cialis contains the active ingredient tadalafil, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors.
Tadalafil works by inhibiting the enzyme PDE5, which is responsible for the breakdown of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penis.
By inhibiting PDE5, Cialis helps to increase the levels of cGMP, leading to relaxation of smooth muscle cells in the penis, increased blood flow, and thus, improved erectile function.
Cialis is known for its longer duration of action compared to other ED medications, lasting up to 36 hours, earning it the nickname "the weekend pill."
Malegra (Sildenafil):
Malegra contains the active ingredient sildenafil citrate, which is also a PDE5 inhibitor.
Similar to Cialis, sildenafil works by inhibiting the enzyme PDE5, leading to increased levels of cGMP and relaxation of smooth muscle cells in the penis.
However, Malegra typically has a shorter duration of action compared to Cialis, lasting around 4 to 6 hours.
Malegra is available in different formulations, including Malegra 25, Malegra 50, and Malegra 100, each with varying strengths of sildenafil.
In summary, while both Cialis and Malegra work by inhibiting the enzyme PDE5 and increasing levels of cGMP to improve erectile function, they differ in their active ingredients (tadalafil vs. sildenafil) and duration of action (up to 36 hours for Cialis vs. 4 to 6 hours for Malegra).
