It has a strong antitussive effect, and has antihistamine, smooth muscle spasm relief, anti-inflammatory and local anesthetic effects. The antitussive effect usually appears 30-60 minutes after taking the medicine, and the effect lasts for 4-6 hours or longer.

It can inhibit the synthesis of prostaglandins and has antipyretic and analgesic effects

It is a central nervous system stimulant that can enhance the antipyretic and analgesic effects of acetaminophen and reduce central nervous system inhibitory effects such as drowsiness and dizziness caused by other drugs.

It is an antihistamine that can relieve runny nose, nasal congestion, and sneezing symptoms.

It has antipyretic and sedative effects

Chloroquine mainly acts on erythrozoites, and after 48 to 72 hours, the schizonts in the blood are killed. This product is ineffective against the infrared stage of Plasmodium vivax malaria, so it cannot cure Plasmodium vivax malaria. It can cure falciparum malaria. Chloroquine is ineffective against the infrared stage and has no direct effect on gametocytes, so it cannot be used for etiology prevention and interruption of transmission.

Analgesic, anti-inflammatory, antipyretic, anti-rheumatic, inhibiting platelet aggregation

It is a medium-acting sulfonamide drug with a broad-spectrum antibacterial effect. It has antibacterial effects on some strains of Enterobacteriaceae such as non-enzyme-producing Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, Klebsiella, Salmonella, Shigella, gonococci, meningococci, and Haemophilus influenzae. In addition, it also has antimicrobial activity against Chlamydia trachomatis, Nocardia asteroides, Plasmodium falciparum, and Toxoplasma gondii in vitro. Sulfonamide drugs are broad-spectrum antibacterial agents. They are similar in structure to para-aminobenzoic acid (PABA). They can compete with PABA for dihydrofolate synthase in bacteria, thereby preventing PABA from synthesizing folic acid required by bacteria as a raw material, reducing the amount of metabolically active tetrahydrofolate, which is an essential substance for bacteria to synthesize purine, thymidine and deoxyribonucleic acid (DNA), thereby inhibiting the growth and reproduction of bacteria.
