Impotence, or erectile dysfunction, is the inability of men to achieve or maintain an erect, hard penis suitable for sexual activity. Kamagra Effervescent tablets, which contain 100 mg of this medication, are used to treat insufficient blood flow into the penis. An erection is the body's natural reaction to sexual stimulation, and Kamagra 100mg relaxes the blood vessels in the penis, increasing blood flow. But, in order for these tablets to function, you must be sexually aroused. There are four flavors of Kamagra 100mg available in tubes, each containing seven effervescent tablets: banana, pineapple, orange, and strawberry.
